Electronics:

This sections deals with all electronics and where to buy them for cheap. There are tons of electronics that you can buy, but most of them have no utility or are a subset of some other electronic, doing the same thing. I think, a laptop and a phone are electronic that justify their existence. Apart from that a TV or projector is nice to watch and get entertained on big screen (although for most people, a laptop screen is big enough to satisfy them). But since TV and Projectors have gotten so cheap, it won't make a big hole in your pocket. Then there are hard disk or USB sticks that you might need for making a backup of your data. Everything else out there under the pretext of smart electronics is non sense junk. I buy this junk too, so I've listed them below :(

Lastly, the real innovation in electronics for the past decade has been LED bulbs. Those are worth your money more than anything else, as they really have innovated if you know what innovation means !!

 

 

Laptops:

Laptops shouldn't cost more than $300 in general. You can usually get very good laptops in this price range. Walmart Black friday sales are one the best times to buy these sub $300 laptop. Other than that, ebay seller "vipoutlet" also has refurshied (but like new) laptops for sale every once in a while. I've bought multiple laptop, TV from them, and they all looked like new. They also have 20% off coupon from time to time, which can fetch you a pretty good laptop for less than $250. I've come to know that vipoutlet is a resale arm of walmart (i.e items returned at Walmart are sold here), so all the items are inspected and most of them are in nearly new condition.

This is the link to vipoutlet store: https://www.ebay.com/str/vipoutlet

Other good place to buy laptop is at Walmart. They have decent sales all year along, and you can always return it without any hassle in store. Sometimes, you will find incredible deals on laptops by looking on brickseek for laptops on clearance. BestBuy used to have some good sales, but as of 2021, I haven't found a single laptop priced to sell for the last 2-3 years (since 2019).

DELL: One other good place to buy laptop is www.dell.com, as they have sales all year around. Around BF, you can get a lot of good deals. Their laptops are sturdy. Their customer service is also very good. I've one Dell laptop in my possession that I bought used for $95. It has been running fine for the last 5 years with Linux installed on it. These laptops are built to last based on my limited experience. Look in "stores" section for more details.

When you buy a laptop or a desktop, it has 2 kinds of memory. One is the permanent memory, which is the hard drive, while the other one is volatile memory which is the DDR Memory. Read in "Memory section" for more details.

Performance of your computer is mostly determined by the processor type and the DDR memory connected to it.  Laptops with large DDR memory and faster Hard drives with a decent processor run faster than those with lower specs. A decent DDR memory requirement is 8GB (4GB DDR memory laptops run too slow with Windows, though they do just fine with Linux. However if you open a lot of tabs in Firefox, you may see that 4GB memory is used up completely, and laptop comes to a near stall). Regards to Hard drive, a faster Hard drive improves performance. SSD are faster than mechanical Hard drive, so go with SSD if possible. A decent Hard drive size is 500GB or so. You will never need more than 500GB (unless downloading popular paid games). If you do run out of space, start compressing your files using open source programs as gzip, etc. That will reduce your file size by a factor of 5. If you still run ou of space, buy some external Hard drive or USB drives, those are really cheap. You can get 1TB drives for <$80 as of 2021.

It's possible to replace both DDR memory and Hard drive in most laptops. Replacing DDR memory is super easy and is a 10 minute job. Replacing Hard drive is tricky, and not always possible. So, I always try to buy a laptop with low DDR memory (since they are usually cheaper), and then replace the DDR memory myself (buying 2X8gb memory modules cost about $50). Don't bother with Hard drive. It has a little effect on how much time it takes for your laptop to start. Most of the laptops I've are with Hard drives, and I never see any issue with performance. See below for details.

So, for extra $150, you can buy 16GB DDR memory and 1TB SSD drive, making your $250 laptop a power house.

 

 

DDR Memory Modules:

You will need to buy DDR memory module if you plan to replace the DDR memory for your laptop to get better performance. Once you get to 16GB of DDR memory, adding additional memory doesn't help, as 99% of the users are never going to exceed 16GB of memory requirement, no matter how many apps you have open. Laptop memory are usually SODIMM, so look for those modules only. Many memory modules are exclusively for desktop, they won't fit in a laptop.

You can get 4GB memory modules for around $20. So, for 8GB memory, you may buy 2X 4GB modules for $50 or less. For 16 GB memory, you can buy 2X 8GB modules for $80 or less (amazon often has these on sale for less than $50). I would recommend buying 2X 8GB as these are usually on sale and heavily discounted. You can even even get 2x16GB for less than $100. You don't have to go for the fastest speed, as speed of memory has negligible effect on performance for everyday activities. Below is a recent deal on amazon for a fast 32GB DDR module. 2X 32GB modules (for a total of 64GB) on sale for $286. Going by the rate of $10 for 4GB, it should be around $10*16=$160 for 64GB. So, it's very expensive to start with, as these bigger modules sell for a premium. Of course you never need these large memories for any laptop (and lower end laptops may not even support such large memories). So, don't go for a deal, just because a lot of sites are heavily promoting it. It may still be a pretty bad deal for your laptop.

  1. 2X 8GB:
  2. 2X16GB:
  3. 2X32GB:

Usually you need to buy 2 modules of same size, as most laptops have 2 memory slot. The easiest way to find out compatible memory for your laptop is to take out existing memory, look at the model number, brand and size. Then look for same brand, or some other brand similar is size. Not all processors support, all Memory type, so you may be limited in what DDR memory modules you can put in there. You don't need to replace both memory modules at same time, you can have 2 different brands. Although it's recommended to have both modules the same. I've never encountered issues myself having 2 brands in the 2 slots.

PRICE:

2021: Good Price to buy DDR module is around $2/GB - $3/GB as of 2021.

2023: As of Apr 2023, price for 2x16GB modules is ~$60, or < $2/GB. These prices are crashing hard.As of July, 2023, good price to buy is $1/GB.

 

 

Hard Drives:

There are 2 kinds of hard drives on market.

  1. Mechanical Hard drives: These are traditional ones and have mechanical moving parts, i.e they have a spinning disc, motor, moving pin, etc. These hard drives are the ones that used to be in laptops, and make a sound when spinning. They have spinning speed specified as 5400 rpm or so. If the name of a hard drive doesn't say "SSD" on it, that means it's a mechanical hard drive. However, these hard rives are very susceptible to damage due to hard disk falling down, getting knocked off, getting dirt/moisture, etc. I had 3 of these external hard drives that were just used for archive purpose couple of times a year, and they all died within 2-5 years. They die so suddenly, that your backup may be lost forever, unless you made a backup of the backup. I've completely given up on mechanical hard drives, since they are so unreliable and die so fast. Once you lose data, you will never buy these again. Also, it's impossible to recover data without paying hundreds and thousands of dollars to the manufacturer. Surprisingly, the mechanical hard disk that come pre attached in a laptop, last much longer. So, not sure why the quality of these external hard disk is so poor. These have gotten very cheap, and you can grab a 5TB HD < $100. Deals abound all the times on amazon, bestbuy, walmart, etc.However stay away from these even if they go for free.
    1. One such deal is here: https://slickdeals.net/f/15183859-5tb-wd-easystore-external-usb-3-0-portable-hard-drive-89-99-free-shipping?src=frontpage
  2. SSD Hard drives: These are counterpart of mechanical hard drives, but with no moving parts. They are similar to USB sticks, where solid state transistors store data, so it's like DRAM, but with permanent storage. The used to be very expensive (about 10X the price of mechanical hard drives), but as of 2021, you can find 1TB SSD disk for < $100. As of 2022, 2 TB SSD are around $100. Most of the time, you don't need more than 1TB for archiving purpose. If 1 TB gets small, compress your data before you store it on hard drive. then uncompress it while using. Compression/uncompression is very fast, and save you 2X-5X the space.  Other thing to watch out for an SSD is how many times can you write to an SSD, before it fails. This is expressed as how many TB can you write on it. Most 1TB SSD have 500 TBW rating meaning you can write 500TB of data on it, before it will start degrading. Since the drive size is only 1TB, it implies you can write the whole drive 500 times over it's usable life. This sounds like a short life, but writing 500 times on that full size will usually take 10 years or so with normal use. NOTE that the SSD hardware/software inside will make sure to spread writes evenly over all locations, so you don't end up writing unevenly - i.e too many writes to one particular location, and too few writes to other. There are 2 kinds of SSD hard drive interfaces:
    • HDD type interface: This has same size and same connector pins as you would see in a "mechanical hard drive". That makes it easy for replacing a "mechanical hard drive" from an existing laptop/desktop with this SSD drive. People usually buy these to make their older laptops run faster, as SSD even with this slower interface are still 10X faster than spinning drives. These slower i/f are needed to keep compatibility with existing connectors.
    • M.2 interface: This is the interface that is supported by all newer laptops that come with SSD in them. This looks more like DDR memory modules, and has connectors on 2 short sides. This interface supports many protocols over it's pins, most common being PCIE Express protocol and less common being SATA. On this PCIE Express architecture, support for NVMe (Non Volaile Memory Express) spec is provided. Before NVMe, SSD were made using PCI Express bus, but using non std interface spec. NVMe came as a standard, which made it easy to have just one driver for supporting SSD communication. Support for NVMe comes from hardware controller attached on the SSD side. These kind of SSD are sold in market as "M.2 NVMe PCIE SSD". These are the one that you should buy if your laptop has a M.2 slot.

As we noted above, speed of your laptop is determined by the speed of your hard drive (NOT the size). Since these SSDs ar 10X faster than mechanical hard drives, your laptop boots up within seconds, and never seems to be crawling to death (that usually happens beacause older mechanical hard drives over time get very slow). If storing files is is your primary purpose, then an external hard drive would be better as it would have longer life.

Brand wise people seem to prefer Crucial and Samsung for Hard drives, as they have very reliable performance and are top of the line. Samsung EVO series is usually more expensive than Crucial MX 500 series, so get Crucial MX 500 as difference in performance and reliability is negligible.

Other thing to note is that DDR memory go for $10 for 4GB or $2.5K per TB. SSD Hard drives go for $100 per TB, while mechanical hard drives go for $20 per TB. So, DDR memory modules are about 100X more expensive than mechanical hard drives for same stiorage capacity. This is  all due to differences in design of Volatile and Flash Memory, and Volatile memory using 6 Transistor design compared to 1 transistor design for Flash. and changes to tech to make the memory non volatile.

Replacing or upgrading with an SSD:

If you have a older laptop, you may have HDD, or a SSD. You may also have extra slots in your laptop for an additional HDD or SSD. Upgrading your laptop to take advantages of SSD is very simple.

  1. Adding Memory to Extra slot: In such cases, you should use the extra slot and install a new SSD. The extra slot may either support 2.5 inch memory or M.2 memory. If you have HDD currently, then the extra slot will support 2.5 inch HDD/SSD, while if you have M.2 SSD currently, then extra slot will support either 2.5 inch SSD or M.2 SSD. Look what your laptop by searching on youtube and how to replace it.
    1. No cloning or anything else is required. Just open the laptop, put right kind of 2.5 inch or M.2 SSD. 2.5 inch SSD can use exiting screws and cover, so nothing new to buy. For M.2 SSD, you may need to buy "bracket" to hold the SSD in place. sometimes, these are provided with the laptop, but generally ot. You can buy them on ebay for $2-$3. No need to buy heastsink, it's not needed.
      1. Bracket for Dell laptop (4 will cost around $11) => https://www.ebay.com/itm/284399831280
    2. Attach the memory to newly bought bracket (which itself should be attached to the motherboard), close the cover, and turn on your laptop. Search for "format partition" on windows. You will have to format the partition, before Windows will start seeing it (it's not automatic).
  2. Replacing Memory in Existing slot: In such cases, we want to replace the existing hard drive or existing M.2 Memory. This is tougher, as all data and OS is on existing HDD or SSD, so we'll need to make sure that all this data and OS is transferred to the new SSD.
    1. Manufacturers of SSD provide free clning software. Use that to clone all data from existing drive to new SSD. New SSD will need to be attached to the USB port or some other port of the laptop, so that copying can take place between the old and new drive. Make a backup copy of existing drive in a spare standalone USB or some other storage device. This will save your day, in case something goes terribly wrong, and data gets corrupted on existing drive.
    2. Once cloning is done, open the laptop, replace the existing HDD or SSD with the new one. Restart the laptop, and it should boot up seamlessly.

PRICE:

2021: Good Price to buy SSD Hard disk is around $0.07/GB - $0.08/GB as of 2021.

2022: As of 2022 end, you may get these for $0.05/GB, so a 1TB SSD for $50) - So, these are about 50X cheaper than DDR modules of same capacity.

2023: 1 TB SSD is going for ~$35 on amazon. So, prices are crashing hard.

 

 

Monitors:

Monitors are not really needed if you have laptop. Get a 17 inch laptop if you need bigger screen. Sometimes you do need a > 22 inch screen or dual screen. In that case, attaching a monitor to a laptop makes sense. You can easily get a 1080P monitor with 27 inch for < $100. 4K monitors are expensive and usually run north of $200. My price target for any 1080P monitor is around $50.

 

 

USB memory sticks:

These USB memory sticks are similar to SSD hard disk as far as physics of storage is concerned. They have USB 2 or USB 3 as their transfer interface. USB 3 is faster speed, so those cost more than USB 2 sticks. USB 2 sticks are mostly obsolete now. These are also very reliable. However, their sizes are limited, with max size memory stick that you find being limited to 256 GB or so. Most of the memory sticks that you see on sale are smaller sized memory sticks as 32GB. As of 2021, you can find 128GB memory sticks for < $10, with 32GB memory sticks going for a dollar or two. I love USB memory sticks for multiple reasons:

  1. They are cheaper than SSD. You can find 10 USB memory sticks (each 128GB) for < $100, while equivalent SSD for 1TB will cost at least $100.
  2. They are very reliable. I had around 10 USB memory sticks for more than 10 years now, and none of them have failed. By contrast, mechanical hard drives failed with 100% certainty in first 5 years. I would suggest to store all your archive data in these USB memory sticks. Of course you can't store everything in one stick, but if you have around 10 of them, you can store all your data by compressing them.

USB interface: When looking for a USB stick, try to get with USB-C interface. Those are usually expensive, but as of 2022, you can get them for almost the same price as USB-A  interface ones. Since most laptops/phones now come with USB-C interface, it's future proof. USB-A ones are OK to get when on fire sale, as most newer laptops still have at least 1 USB-A interface (though this might change in next few years, possibly by 2025)

PRICE: Good Price to buy USB Memory sticks is around $0.10/GB as of 2021. Of course 4GB memory stick is going to be more costly (per GB) than larger sized stick. A 4GB memory stick for $1 is a good price, as you can use it to burn Linux OS and keep it burnt for ever. These are slightly more expensive than SSD Hard disk.

 

 

SD Memory cards:

These are similar to USB memory sticks. But instead of being a stick with USB interface, they are meant to be inserted in cameras, with a SD interface for memory. Their cost is similar to USB memory sticks as it's the same technology. I use these memory sticks too for storing data too (instead of just using to store pics). They are equally reliable as USB memory sticks. They come in 3 different physical sizes asshown below:

  • Standard SD: This is the largest size measuring 32mm x 24mm. These cards are not sold anymore.
  • Mini SD: This is the smaller size measuring 21.5mm x 20mm. This is the slot you see in your PC and in your camera for inserting SD cards,
  • Micro SD: This is the smallest size measuring 15mm x 11mm. This is the most common SD card being used. It's used everywhere in phones. You should always buy a Micro SD card that comes with a mini adaptar. Mini adaptar allows this Micro SD to be inserted into Mini SD slots, so that you don't have to buy a separate Mini SD card to use in your camera or laptop. 

Here's one recent deal for SD Memory cards at Costco:

 PRICE: Good Price to buy SD memory cards is around $0.10/GB as of 2021. These are same price as USB memory sticks.

 

 

Phones:

Phones shouldn't cost more than $100, and that also for a very powerful phone. Many times your phone provider (Tmobile, etc) allow you to buy a phone for free via 24 month monthly credit, but you still have to pay sales tax. Those phones are decent phones, but usually cheap ones. You end up paying around $30-$40 in taxes itself (depending on your states sales tax rate), so I avoid buying these from carriers. Tmobile usually has offer for free phone by exchanging a used ones. You can buy these elgible used phones for $10 on amazon or ebay, and use that to get a new phone. One such phone is here: https://www.amazon.com/dp/B084GXS58R. Net cost might be $50 or so after accounting for everything. ebay is another place to buy cheap refurbished phones from authorized sellers.

I look for 3 things when buying a phone: a replaceable battery, a replaceable SD card and of course a low price. You don't need a high end phone with fastest processor, as phones from 20 years back still work as phones for making calls, texting, etc. Chips have gotten 1000X more powerful in the last 20 years, and there is nothing that we can do on a phone, that requires 1000X more computation. It's still just making calls, getting texts and browsing internet.

  • Battery: Unfortunately very few phones have replaceable battery now a days. LG V30 was the last phone with replaceable battery. There are few older phones from Samsung that have replaceable battery. You need replaceable battery to keep your phone running beyond 4 years, as batteries die within 4 years. Replaceable battery are also good to keep as spare, so that if your battery dies in middle of no where, you can swap the dead battery with spare one and keep going (instead of waiting to find a charging spot).
  • Memory card: You may find a lot more phones with replaceable SD card than the ones with replaceable batteries. Replaceable SD card for your phone allows you to increase the memory size of your phone. A phone that has soldered memory card, charges you a lot of money to go to a larger sized memory (~$200 or so). if you have replaceable memory card, you can just buy a 256GB card for $25 or so, instead of paying $200 more. A replaceable memory SD card is also very handy to move contents from your phone to your PC, as you just take out the memory card, transfer all the contents to your PC, and wipe out the card. With soldered memory cards, I always spend a lot more time and effort transferring content to my laptop.
  • USB-C Port: Look for a phone that has USB-C port, as those charge the phone fast, and chargers for USB-C are getting cheap now (<$10). The USB-C cable as well as the charger come with the phone most of the time (unless you are buying an expensive phone). Also, 1 cable and charger can work for all phones that has USB-C port, so it's convenient to carry just 1 charging accessory for all phones.
  • 4G vs 5G: 4G and 5G refers to the generation of cellular transmission used. Look in "cellular standards" section for details. Look for a phone with 5G since prices have come down a lot for 5G phones. 4G phones are the older ones, produced before 2020. For me, 4G phones work just fine, as I'm not on the road for long, and don't use internet a lot. Personally, I haven't noticed speed difference when browsing on 4G vs 5G. However, 5G makes your phone future proof, so buy it if you can get one for < $100. Prices for 5G phones will possibly come down to < $100 by 2023. For now and for next few years (as of 2022), 4G phones will suffice.
  • GSM vs CDMA: Phones in USA used to either work on CDMA or GSM for pre 4G tech. T-mobile, A&T used GSM, while Verizon used to use CDMA. Sprint also used to have CDMA phones, but with it being a part of T-mobile now, it will be using GSM (CDMA will be phased out over time) GSM phones had sim cards, while CDMA phones were tied to the carrier with no sim cards to switch. These CDMA phones won't work in countries like India, since you can't switch SIM cards (GSM phones were fine). Now, all phones starting from 2018 onwards have chips for 4G and 5G, which don't rely on GSM or CDMA, but have common 4G-LTE chips or 5G NR chips (since that is what all carriers in USA support). All these phones also support 2G tech (GSM or CDMA) as fall back method which may have issues depending on your phone type. But if you ignore the fall back method, they should all work fine in 4G. In conclusion, whenever you buy a phone, buy a phone with a SIM card (i.e newer phones made in 2018 and beyond).
  • UNLOCKED: Always try to buy unlocked phones which cost a little bit more than locked phones. If you are with T-mobile, you are in luck. You can buy a T-mobile locked phone, which usually sell for lower price than locked phones. T-mobile will allow you to unlock the phone, after a month or two of service for free. Never hurts to save a few extra bucks.

IMEI (International Mobile Equipment Identity) number: Many times when getting tech support for your phone or activating a new phone, you will be asked for IMEI number of your phone. IMEI number is a unique identification or serial number that all mobile phones and smartphones have. GSM phones have IMEI number while CDMA phones have MEID number. It is normally 15 digits long. It's tied to the device and has nothing to do with your phone number or your carrier. IMEI number reveals a lot of hardware details about your phone, and phone carriers may enable/disable phones based on IMEI number (i.e if the phone is lost or stolen). It's always a good idea to keep IMEI number of your phone written and stored in a safe place, incase your phone is lost.

There are several ways to get a IMEI number: Some of these are:

  • To get the IEMI number, dial *#06# (on the keypad of your phone), and it will pop up a box with IMEI number.
  • Under "settings" section of phone, you will find something similar to "About phone". This usually has the make/model and IMEI number.
  • If that doesn't work, you can just look on the sticker on the box, which will show the IMEI number.
  • If your phone back cover may be taken off, then the back side (right under the battery pack) also has the IMEI number written on it.

Here are few good phones I've bought in the last couple of years from ebay:

  • Motorola XT1925-6 Moto G6 32GB: https://www.ebay.com/itm/113248617461 All motorola phones have worked flawlessly for me. This one is very sturdy built, I bought it for $80 from ebay as a "open box" item from seller "vipoutlet". It was almost new. Has been working for 3 years with no issues. Since then I've bought few more of these, and all are still working great. This does NOT have a replaceable battery, though it does have a replaceable SD card slot. It does have a USB-C port which is a plus. This is a 4G phone.

  • LG V20: https://www.ebay.com/p/18007923729?iid=112731504843 => This is the last LG phone with replaceable battery. All LG phones since LG G series (LG G2, G3, G4, G5, V10, V20, etc) have this bootloop issue where the LG logo will appear on powering up, and this logo will not go away. The bootloader is just looping around, and going nowhere. Each and every phone that I bought from LG had this issue, with the exception of V20 (so far). The phone may show up the issue in a year,or 2 year. So, you can still use the phone for a couple of years, but once the phone shows bootloop issue, it's done. There's no fix, no way to recover anything from your phone. LG denies that their phones have this issue. it's not widely reported, since people move on to a newer phone after 2 years, so very few people get to report the issue. LG V20 is the first phone that hasn't shown the issue even after 2 years. I'll have to give it 2 more years to say for sure that the issue is resolved. The phone does have removable battery and removeable SD card, which is great. The later LG V30, LG V40, LG V50 may not have this bootloop issue, but they don't have removable battery anymore (they do have removable SD card though). LG V20 also has USB-c port, which is a great feature to have, since all newer phones are moving to USB-C charging ports, which charge pretty fast (90% or so charge in less than 1 hour). I bought LG V20 for $100 in 2019 for a open box item (almost brand new), but now you can get these for < $70 (as of 2021). LG V20 is a 4G phone. LG V50 onwards are 5G phones.
  • LG V35 Thin Q: This phone doesn't have a replaceable battery, but is a nice upgrade from LG V20. LG V30, LG 35 and LG V40 are highly rated 4G phones. It costs about $100 buying used (like new) from amazon.

 

UPDATE (May 2022): LG phone issue: Since LG has gotten out of phone business, there are issues that can impact LG phones with little traction. One such issue was "LG IMS has stopped" issue that showed up on various models of LG phones, when an update was pushed by T-mobile. The fix below by Tmobile works for all LG phones, so try this method, and do not rely on other fix provided elsewhere on internet: https://www.t-mobile.com/support/devices/lg-ims-stopped

 

 

Power bank:

These are one of those things that you absolutely need. Most laptops/phones have batteries soldered to them, so there's not an option to swap the battery with a spare one. Power banks generally have a storage capacity of certain Energy. Energy=Voltage*Current*time. This is in units of Watt-hr. However, in practice, Energy is quoted in current*time, ignoring the voltage altogether. That's OK as Voltage is usually 3.7V for most phones, and is assumed to be that level. So, the unit used is A-hr, or generally mAh (1000mA=1A). I would generally go with any power bank that has a capacity of at least 10,000mAh. Phone batteries are generally 3000mAh-5000mAh, so 10K mAh guarantees at least 2 full charges of phone. Even if the power bank is drained to half because it has been sitting idle for a couple of months, we are still guaranteed to get 1 full charge on a phone. If you plan to use a power bank for a laptop (only laptops with USB-C power interface), those power banks will need to have at least 25,000 mAh, so that they can survive 1 charge (~2-4 hrs)

Interfaces: Power banks have 2 interfaces. 1 interface is for charging which you connect to wall outlet, while other is for discharging which you connect to your phone or laptop. A lot of power banks have both interfaces as USB-A interface. USB-A interface supports smaller current only, so charging/discharging is slow. They provide a cable along with the power bank which have USB-A on one side on USB-C on other side so that you can charge your USB-C phones. Power banks which have inbuilt USB-C interface are more expensive, but better for faster charging/discharging. Those with USB-C interface use USB-C for both charging and discharging, which makes it very fast to charge. They laso provide additional USB-A ports (optional) for discharging, so that we can still use these with devices that have USB-A interface. Buy USB-C interface ones if you can find them close in price to USB-A ones.

 PRICE: Good Price to buy power bans is around $1/A-hr (with cables included) as of 2021. A lot of power banks are on ebay and amazon for cheap going for this price. However, not sure about longevity, so buy reputed brands when on sale.

 

 

Wall Chargers for phones:

These are wall chargers to charge your phones. Most phones have USB-C interface now, which can be used to charge phone faster. These are universal, meaning they can be used anyhwere in the world as they accept worldwide voltage from 100V-240V AC, and convert it to the needed DC voltage. Input side of the charger is the AC outlet voltage, while output side is usually a USB-A interface, USB-C interface, or a combination of the two. You should always look for wall chargers that have at least one output port as USB-C. That means these are going to be fast chargers as USB-C has ability to drive more or less current depending on the need of the phone battery.

Nowadays many laptops are charged via USB-C interface, and don't have traditional power outlet+adaptar any more. Such laptops can be charged via these wall chargers, if the wall charger has a USB-C output. That's one more reason to look for chargers with USB-C output port.

PRICE: Price for wall chargers depend on the wattage and whether or not it has USB-C output port. I would say wall chargers should have at least 25W of power (5V*2A for USB-A port to charge a phone, and assuming 2 such ports). Such chargers usually come for free with the phone. Most phones don't provide USB-C chargers. You should buy USB-C ones with wattage of at least 25W. Make sure they come with a USB-C cable (USB-C on both ends) as those cables runs expensive. These sell on ebay for $5 or so (without the USB-C cables). Good ones would be ones with 65W-100W of power rating, as they could charge a laptop too and are future proof. These go for around $10 for 65W charger to $25 for 100W charger (without the USB-C cables). I would say never pay more than $10 for any kind of USB-C charger. Price of these chargers go exponentially high as the wattage increases. 65W ones are more than enough for our needs, and that's also a sweet spot price wise. Few such links on ebay:

Link (65W): https://www.ebay.com/itm/363733309997 => 65W USB-C PD charger for $10 on sale (usual price is $20 for this, but similar ones sell for $12-$14)

Link (100W):  https://www.ebay.com/itm/334324277790 => 100W USB-C PD charger for $25

 

 

TV:

Prices of TV have fallen so much in the last couple of years, that you can now find 65 inch TV for $200 or so (as of 2020). TVs smaller than 40 inch regularly go on sale for < $100. TCL,

Black Friday 2020 had Target selling 65 inch 4K TV for $229. Fast forward 2021, and there were barely any > 65 inch TV for < $500.

Below are the prices I would expect for TVs:

This is based on a 65 inch TV which has an area of ~1800 inch^2, while a 75 inch TV has an area of ~2400 inch^2. So, you get 33% more area, implying about 1/3rd higher price for a 75 inch TV compared to a 65 inch TV. However, there is a premium as you you go to larger size, as making larger LCD panels cost more per inch^2 than smaller LCD panels.

TV < 40 inch => price < $100

TV 40 inch to 65 inch => price < $200

TV 65 inch => price < $250

TV 70 inch => price < $300

TV 75 inch => price < $350

TVs larger than 75 inch are still very expensive to consider. A projector is a better option at that point. Look in the Projector section below.

 

 

Projector:

Projectors are best when you have a wall big enough with height x width > 5ft X 7 ft. Usually you can find at least 1 wall with those dimensions. At that point, the diagonal is about 8 ft, which is equivalent to 96 inch TV. Any TV > 75 inch diagonal costs close to $1K (as of 2022), but a nice projector could be had for under $500. Projector bulbs are the weakest link in making a projector affordable. A projector bulb lasts 3-4 years, and is very expensive (>$100) to replace. However, if your projector usage is very low (which usually is after you had a projector for a couple of years), then your bulb will last longer. They rate the bulb for 3000-4000 hrs. So, if you watch 1 movie everyday, then your bulb will last 3-4 years. More practical use is 3-4 hrs/week, in which case, yor bulb should last 10 years. It's probably better to buy a new projector, then spend money on a new bulb. Don't spend money on extra bulb when buying a projector (all projectors come with a bulb). The extra bulb will just sit idle for a long time, and may have a much shorter life when it's time to use.

Below are few items you need for a projector:

  • 4K projector: Even a 1080P projector would serve fine. There are tons of projectors out there, and hard to decide. I would suggest go with any entryline 1080P projector from Epson.
    • Epson PowerLite 2045 Full HD: This is a very good 1080P projector. I bought it for about $360 ($375 - 5% in Extrabucks) way back in 2018, when ebay used to have good deals. Good old times !! It's 4 years, and still runs great. https://www.ebay.com/itm/31206136056
  • Projector Screen: It's a big screen made of fabric on which your projector displays the picture, as picture displayed on the wall doesn't look good (depends on the wall though). People buy really fancy motorized screens, what you need is just a white thick sheet. That way you can fold and keep it when not in use. The big flat screns are not only expensive but also permanent attachment to wall. There's no visible difference in display quality for fabric screen vs solid expensive screens. I
    • Excelvan 150 inch Projector screen: I bought this on amazon, and it's as good display as you can get. It's made of PVC or something, but much thicker and no crease on the screen. It cost me $20. https://www.amazon.com/gp/product/B0719SVHDF
  • Projector holder: A table or something to keep your projector on. I had always kept my projector on a table on floor, which served fine. I was always scared of making a hole in the roof to attach the projector and NOT knowing what I'm doing. Recently, I switched to the below projector holder which attaches to a wall, so is very easy as a DIY:
    • Wali Entertainment Shelve: Very easy to attach to a wall. Make sure you have a stud finder, so that you nail this thing on to the stud and not to the drywall. It's price is ~$20. I bought it used for $15. You can buy 2 of these, if you want to have more flexibility on different shelves to put the projector on: https://www.amazon.com/gp/product/B00UB062ZQ

 

 

Wireless in ear head phones (aka earpods):

These are the wireless headphones. Instead of going over your head, they go in your ears. Most people call them Earpods, even though that name seems to be reserved for Apple branded ones. Almost all other companies refer to them as "wireless in ear head phones". They aren't worth anything > $30, since you can get good quality headphones for < $30.

A. JLab: JLab isa relatively new audio company founded in 2005. It started by making in ear head phones, but since then has branched into making other audio products. They make economical audio products, and made it in top 5 audio brands in USA. They are based in California. They were purchased by Noritsu, a big japanese company in 2021. They are growing somewhat reputed company making great products at reasonable prices. However, some reviews consider them at the bottom of the pile, with SkullCandy being the worst ones. However, reviews for their headphones are usually great. Their regular price is around $20. If you find them on sale or clearance for < $10, grab them as they usually don't go for much below their regular price. Below are some of their headphones:

1. JLab - GO Air POP True Wireless In-Ear Headphones:

These sell at bestbuy for $20. That's the regular price !! They have 4.5 star rating there, and are the most value that you can get on these in ear headphones.

Link: https://www.bestbuy.com/site/jlab-go-air-pop-true-wireless-in-ear-headphones-black/6472667.p?skuId=6472667

Also at walgreens for $19. Link: https://www.walgreens.com/store/c/jlab-audio-go-air-pop-true-wireless-earbuds/ID=300421313-product

 

B. JBL: JBL is a audio company known for making great audio products. They are a subsidiary of Harman, which is the parent company that has other brands under it too. Harman is a big company employing 30K people in USA, Europe and Asia. In March 2017, HARMAN became a wholly-owned subsidiary of Samsung Electronics and is mentioned on harman.com site as "Harman - A Samsung company". JBL is a very old company (around 80 years) and much bigger than JLab, it's a great brand that makes great reliable economical products (though expensive than JLab). JBL is considered reputed company, and though you pay a little more, but they are considered amongst the top ones for cheap earbuds. I've used JBL. They come in a very nicely packed box, and look and sound amazing. They are the best amongst all the other brands I listed. Some of their great products are:

I. JBL Reflect Flow True Wireless Sports Headphones:

These are usually $60-$70, but go on sale for $30 or so. These are the best according to some reviews, even better sounding than $200 ones from expensive brands. Available in 3 colors. 2 colors show under 1 link, while the black color has a different link, just absurd.

II. JBL Live 300TWS True Wireless Bluetooth In-ear Headphones:

This is also very similar to JBL Reflect. Somepeople claim that it has better sound quality than JBL Reflect. One advantage this has is that it USB-C port for charging, compared to USB mini (type A) that JBL Reflect has. However, JBL Reflect is the newer one. Both sell for about the same price though, when not on sale. On sale, 300TWS goes for about $38.

C. SkullCandy:

People say they are at the bottom of the pile. They are the cheapest ones, but quality is also low. However, reviews seem good

I. Sesh wireless earbuds:

These are also decent and go for $15 on woot quite often.

II. Jib 2 wireless earbuds:

These sell for $30 new on amazon, but refurbished ones may be had for $10 or so. Not bad for the price.

D. TOZO:

This looks like a cheap brand and I found it by accident on amazon. All their earbuds are highly rated on amazon. They all sell for $20-$30 when on sale.

I. T6, T10 and T12 True wireless earbuds:

T6 are highly rated on amazon (200K+ reviews)). I bought these for $22.50+tax, and they regularly go on sale for close to that. There are other versions as  T10, T12. According to a reviewer on reddit, "T12 is best sound-wise, T6 is best for calls, T10 is the cheapest, the differences between them aren't big". They all sell for $20-$30, so go with what suits you. T10 has even more reviews at 300K+, and is highly rated too, but looks like T6 is the newer model, so should perform better.

Link for T6: https://www.amazon.com/TOZO-T6-Bluetooth-Headphones-Waterproof/dp/B07RGZ5NKS => $22.50 on sale (regular price is $60, but never saw them selling for over $30)

Link for T10: https://www.amazon.com/TOZO-Bluetooth-Wireless-Headphones-Waterproof/dp/B07J2Z5DBM => $22 on sale (regular price is $26)

Link for T12: https://www.amazon.com/TOZO-Bluetooth-Headphones-Intelligence-Waterproof/dp/B085DL3KMR => $25 on sale (regular price is $30)

Don't forget to get the $2.99 "3 year protection plan" provided by Asurion LLC on amazon (there's a button to add the protection plan on right side of screen, just below "add to cart"). This will make sure you have the device protected for 3 years for any mishaps. I don't know if they will pay or not, as I've never used them before. Reviews are mixed on that.

 

CONCLUSION: Headphones go for $10 or so. Wired in ear headphones go for free (airlines, audio tours, etc give them for free). Wirless in ear headphones may cost some money due to it's wireless circuitry. In any case, I wouldn't expect wireless earbuds headphones to cost anything > $10 to manufacture. Considering that, I would say go with JBL as they are reputed. They cost about $30 or so, but you don't get reupted brands for less than that. I had no issues with Tozo, JLab and SkullCandy. However, I haven't kep any of these long enough to make a comment on their longevity. The biggest issue with cheap brands is that they die too soon.

 

 

Smart Watch:

Watches became useless with arrival of phones, saving you moneyon watches. Fast forward from 2000 to 2020, and watches are back and ridiculously expensive, and the usage of which was questionable when they came out, and now they are the one of the big fashion accessories. They aren't worth anything > $50, as they practically have no known use except fashion.  Anyway, here are your most economical smart watches:

1. Popglory Smartwatch:

These sell on amazon for $30, but usually go on sale for $25. They have 4 star reviews. Good thing is that they have all measurement devices inbuilt in watch which are only seen in expensive watches (as measuring blood pressure, oxygen level, pulse rate, etc). They are regularly in top 10 best sellers in smart watch. You will need to download their app "heroband III" in order for the watch to work. there are many apps with similar name "heroband 3", those won't work with this watch. You may add a "3 yr protection plan" for only $3 when buying from amazon, so defintely do that, as these things get in harm's way easily. This only comes in 1.4 inch size.

Link for 1.4 inch watch: https://www.amazon.com/gp/product/B08DXS7VCK

2. Donerton Smart Watch:

These sell for $38 for 1.4 inch watch, and $42 for 1.7 inch watch on amazon. However they go on sale or have coupons frequently, bringing the prices down to $30 for 1.4 inch and $35 for 1.7 inch. They have 4 star revies, and look similar to PopGlory ones above. They use the same "heroband III" app to work. They have "3 yr protection plan" for $5 for the 1.4 inch watch. Weird that they don't provide protection plan for 1.7 inch watches. They are regularly in top 10 best sellers in smart watch (along with Popglory). Not sure why the premium of $5 on these watches compared to popglory for same size watch with similar functionality.

LED bulbs:

These LED bulbs have virtually replaced traditional as well as CFL bulbs. LED bulbs are even more efficient than CFL bulbs. These now come in various shapes, sizes and wattage. They also come in dimmable version now. You can find equivalent of 65W and 90W bulbs for a dollar or less. They usually go on clearance at HomeDepot and Lowes for 75% off multiple times a year, which results in a price of $1 or less. Each of this LED bulb uses energy of about 10W or so. Assuming the bulbs are ON 5 hours a day, 365 days a year, they will consume about 20KWhr. since 1 Kwhr costs about 10 cents, They will cost about $2/year in electricity cost. Assuming you have 20 such bulbs which are ON for about 5 hours/day, you will spend about $40/year. These bulbs themselves will cost about $10-$20 assuming you buy 20-50 of them. These will last at least 5 years, so effective cost per year is about $4 or so for replacing these 20 bulbs. You can't buy any bulb, incandescent or CFL, anywhere which cost anywhere close to these (since filament or CFL bulbs last at most a year and cost atleast $5 for 20 bulbs).

LED bulb light type: LED bulbs which have white light (NOT the yellowish light) are my preferred ones, as they are so much better lighting and easier on eyes when reading, etc.

  • Warm White or Warm Light (3000K): These are the ones that give yellow light (similar to what incandescent bulbs used to give, i.e similar to what's emitted at 3000K temperature)
  • Day Light or Cool Light(5000K): These are the ones that you should buy. The light is white (similar to what tubelights give, i.e similar to what's emitted at 5000K temperature). Note: it's called cool light, even though the temperature is higher.

LED bulb Power: The power of the bulb decides the amount of light or intensity of light.

  • 40W/50W LED replacement (consumes 6W-7W) => These are low wattage. Brightness is also low at 500 lumens.Not suitable for big areas, OK for closets, etc.
  • 60W/65W LED replacement (consumes 8W-9W)  => These are the most common ones, regular size bulbs. These are the ones mostly on discount, and available everywhere. Brightness is 600 lumens.
  • 75W/90 W LED replacement (consumes 10W-13W) => 90W is most bright, is bigger size, but is very suitable for ceilings, and places where you read, work, etc. Brightness is really high at 900 lumens. My 90W bulbs show current=137mA @120V (RMS), so Pwr=V*I=0.137*120=16W. Not sure why the pack says 13W. May be current is not RMS current. There are 100W LED bulbs also which are more expensive. These 90W ones will suffice for everything. I haven't seen anything  > 100W equivalent.

 PRICE: Good Price to buy LED bulbs is around $0.50/bulb for 65W equivalent, and $1/bulb for 90W equivalent. 90W equivalent are rare to find, so grab them fast when they go on clearance.

 

 

Batteries:

There are AA (larger diameter, thicker batteries) and AAA (smaller diameter, thinner batteries) batteries which are most commonly used in devices. There are 2 kinds of batteries => Rechargeable and non-recharable. Rechargeable batteries cost more than non rechargeable batteries.

Re-Chargeable batteries:

These cost about $1 to $1.50 per battery. You need to buy a charger too, which will cost $5 or so. Eneloop batteries are the best.

Non Rechargeable batteries:

These cost about about 10 cents per battery.Their regular prices are lot higher, but you can find them for 5 to 10 cents during sale.Some folks think that rechargeable batteries are cheaper in long run, so why bother with non rechargeable batteries. This may be true in some of the items, that drain a lot of battery. But in most of the cases, non rechargeable batteries are cheaper. Rechargeable batteries die in about 5 years. So, in order to cost the same as Non rechargeable batteries, you have to completely use the battery once every 3 months. If your batteries aren't getting drained that fast, it's better to stick to non rechargeable batteries. The only places I put rechargeable batteries are kids toys with motors, portable lights, drones, etc. Everything else, just buy non rechargeable at these sale price, and you would be better off.

These usually come on sale at bestbuy (pack of 48 for $6).

These also come on sale at OfficeDepot+OfficeMax (They are one company now) for free after rewards (you get back rewards for the price you paid for battery). Rewards expire in 3 months, and you get them immediately after pickup. You can buy almost anything with rewards, except gift cards. Also rewards can't be rolled, i.e if you use your older reward points to buy batteries which are free after rewards, your reward amount will be reduced by the older reward points you used. As an example, if you buy batteries and pay for it completely using reward points, you will earn nothing in new reward points (no 100% rewards back). Since everything is expensive at OfficeDepot + OfficeMax, you can always buy postage stamps with these rewards (if you can't find anything else for a reasonable price). However, don't amass too much in rewards, else you will be stuck with stamps to pass on to your grandkids.

PRICE: Good Price to buy Batteries is around $0.10/battery for non rechargeable ones and $1 for rechargeable ones (both for AA batteries). AAA batteries should go for lower price since they have less than half the capacity of AA ones, butunfortunately they sell for only a little bit cheaper than the AA ones.

 

 

3D Printers:

3Dprinters have been in press and availed as the next big thing for the last 5 years. However they never took off in a big way probably because there are no big and fashionable electronics companies in it. I've never owned a 3D printer, but I would like to buy one someday when the prices go to < $100. They can be used to make plastic parts for things that break in your appliances, eletronics, etc that make that device unusable. Of course making these replacement parts using 3D printers is neither cheap nor easy. However, it may serve as good learning experience. 3D printers do require a lot of tinkering to get it working right. Expensive ones come ready out of the box. These are some popular 3D printers (taken from the web, I've no personal experience):

  • Creality: Bet for a beginner to learn and make mistakes. Ender 3 is low end and regularly sells for $99 at microcenter. Highly recommended on slickdeals
  • Prussa: Used in a lot of companies. It allows you to minimize your early mistakes, so better than Creality
  • Ultimaker: Best printer, and is ready out of the box (no diy abilities or tinkering needed) but it's expensive

These are some of the recent deals. Read thru comments as they have a lot of valuable feedback on what works, info for beginners, etc

PRICE: Good price, depending on the brand is under $100. It's hard to justify the investment for anything over that.

 

 

Wires/Cable, Outlets, Extension cords, etc:

I'm talking about wires that you need to run around your house. You will need to buy these if you are going to be running wiring outside or inside your house. Electricians are very expensive, so doing it yourself is not only easy on pocket, but also really simple. An ex of when you might need to run wires around your house is when you are installing a mini split AC (if you need a dedicated outlet or disconnect box). Look in "Power Transmission" section under "Education" for more in depth understanding of the wires. Our price target should be 50 cents/foot for the wires running inside the house. These are called "Romex" wires. Not sure, why these wires are more expensive than similar rated "extension cord" wires. Maybe they have better insulation, and better built ground wire.

There are also various "outlet wall adaptar" that have 6 outlets or so that plug into the wall. These go for $3 or so when on sale (though I was told that Dollar stores carry these for a dollar).

Extension cords are thick wires that you run when you have an external equipment that can't reach an outlet. These are somewhat inexpensive costing $20 or so, for 100 ft wire. Our price target should be < 20 cents/foot. These come in both outdoor/indoor variety.

 

 

 

Sticky Deals:

 

 

OfficeDepot / OfficeMax - Free Non Rechargeable AA/AAA batteries after rewards  => every few months

This deal is there almost every month. Lately, as of 2023, it's more and more uncommon. Comes every few months now. Limit is 2. Better to buy 2 sets of 24 batteries (AA or AAA depending on need, you can mix and match). Everything is overpriced at OD, so use rewards to buy stamps. Below are the deals:

07/10/2022: Energizer indoor wifi security camera for $17 at walmart: 

Decent price for a security camera. It's indoor and no battery (so need to have power plug close by). You may put a SD memory card in it, and get recordings saved whenever there's motion. Hard to find any security cam for this price.

05/14/2022: Walmart - 65 inch 4K Series 4 TCL TV for $400:

This deal is for Series 4 TV. Comments state that Series 6 is lot better than Series 4, but Series 6 is more expensive too. Similar TCL TV sold in 2020 Black Friday for $230 (see 2020 BF deals section). This is an OK price for 65 inch TV considering prices have gone up a lot in 2021 and 2022.

Another deal is for refurbished version of this laptop sold by walmart. This looks to be out of stock most of the time (3rd party sellers sell it for more than the price of new one).

https://slickdeals.net/f/15750811-17-3-hp-laptop-refurb-i5-1135g7-1920x1080-ips-8gb-ram-512gb-ssd-379-free-shipping

Walmart link: https://www.walmart.com/ip/seort/353306478

Conclusion: I've used this laptop. It's very nicely made, and RAM can easily be upgraded (look in slickdeals comments). This is good price. It has come on sale at $500 multiple times in the past couple of months. I haven't seen refurbished one for $379 though.

 

 

05/01/2022: Home Depot - 6 outlet wall adaptar for $3:

https://slickdeals.net/f/15749617-woods-6-outlet-wall-tap-adapter-3-25-free-store-pickup

I've used this. This is good price. It sticks to the outlet firmly. It has no USB-C/USB-A, but you don't need those. You can always buy those USB adaptars for < $10. Amazon sells these wall adpatars with USB-C/USB-A for $10 or so, but those are not worth the extra $7.

 

 

04/13/2022: Woot - skullcandy wireless earbuds for $14 (free shipping for Amazon Prime Members):

https://slickdeals.net/f/15720454-skullcandy-sesh-true-wireless-bluetooth-earbuds-13-99-free-shipping-for-prime-members-13-99?src=frontpage

It's hard to find USB-C drives for price of USB-A drives. It's a good price for 64GB ones. Kingston is a known brand.

 

 

04/09/2022: BestBuy - USB-C 90W wall charger with 8 feet cable for $25 (Now as of 04/11/2022, it's $11):

https://slickdeals.net/f/15717088-insignia-90w-usb-c-wall-charger-w-8-cable-in-store-pickup-24-99-at-bestbuy?src=frontpage

This is a great deal. You can charge or laptop/phone, etc very fast. It has 8 feet USB-C cable too, which by itself would cost about $10.

UPDATE: As of 04/11/2022, price has dropped to $11. There's a limit of 5 for online ordering. Get all of them, as it's crazy deal !!

04/09/2022: BestBuy - USB-C Portable Powerbank (~100Whr) for $40 :

https://slickdeals.net/f/15718651-insignia-26-800mah-usb-c-portable-charger-w-65w-power-delivery-39-99-free-shipping

This is a great deal. You can charge or laptop/phone, etc, and never have to worry about losing power. Best part is it's power capacity is just 100W-hr, so you can carry it on planes as carry on luggage. Airlines rules don't allow any battery over 100W-hr to be carried on flights (neither checkin nor carryon). Batteries are never allowed checkin luggage anymore, they always have to be in carryon luggage). "Open box- like new" are also avilable for $32.

UPDATE: As of 04/10/2022, the :open box like new" ones selling for $32 aren't available anymore for shipping. Orders getting cancelled.

 

03/31/2022: Microcenter (in store only) - MSI Katana laptop for $800:

https://slickdeals.net/f/15699310-new-customers-15-6-msi-katana-gf66-gaming-laptop-i7-11800h-rtx-3060-16gb-ram-1tb-ssd-144hz-ips-799-w-text-coupon-in-store-only-at-microcenter?src=frontpage

I usually don't go for laptops over $500, but with prices going up so high in 2021 for laptops, and dearth of laptops for < $500, this is a good deal as MSI makes good quality gaming laptops. You spend a bit more, but get lot more. 1 year std warranty + use your chase credit card to pay for it (that extends the warranty by an additional year). This is instore only deal, so you are out of luck if there's no microcenter store close by to you.

03/29/2022: Target - 10 pack LED bulbs for $6 => expiry unknown

https://slickdeals.net/f/15694411-target-has-led-60w-10pk-light-bulbs-soft-white-up-up-free-store-pickup-or-free-shipping-for-red-card-holders-5-49

Not the cheapest, but at 50 cents per bulb, it's a good price. However, this is target brand, up&up, and based on reviews these may not last 5 years or more. They do have 1 yr warranty though. Better to wait for branded ones like GE, etc to go on clearance at Home Depot, Lowes, etc.

 

 

03/17/2022: BestBuy - Asus 17.3 inch chromebook laptop for $189:

https://slickdeals.net/f/15684649-asus-17-3-chromebook-intel-celeron-n4500-4gb-ram-32gb-emmc-189-or-less-w-sd-cashback-free-s-h

I'm not a fan of chromebook, and have always avoided buying them. However, this laptop just works great. It has 1080p screen, has usb-c charging (no separate power port,  but uses usb-c as power port), runs sleek even with multiple tabs open. The only downside is that permanent storage, (which is eMMC in this case, and NOT a hard drive) is small at 32GB. It can't be expanded as it's soldered. You can insert SD card upto 128GB (may be higher is also supported) and use that as extra hard drive storage. At $189 + 6% SD cashback, it's a very good value. Open box-Excellent is $10 less. You can always install linux and use it for your everyday task.

UPDATE 03/27/22: Now going for $149. A steal at this price, as it would cost more to make it for $149. Open box-Excellent is $10 less.

This is not the lowest price for a 2X 8GB DDR4 memory, but decent enough if you need one.

 

 

11/14/2021: Walmart - 256 GB USB 3.0 flash drive for $20

https://slickdeals.net/f/15399019-sandisk-256gb-ultra-usb-3-0-flash-drive-19-28

This is the lowest price for a 256GB drive. It costs $0.08/GB. 1 TB of such drives will cost around $80 about on par with SSD drives. As I said, these are good to have as a backup to SSD. Buy at least 2 to get free shipping.
