Links to various products I often bought/buy, Part 2

Part two of a list of various products I bought on AliExpress. I bought some of them more than once, so I can comment on both the product itself and the store.

You can find the previous part here.


Rather than start a new thread, I'll make a brief announcement here.
I spotted the 150 W electronic load board I reviewed a while back on AliExpress for $8.66 including shipping — link
Might come in handy.


2S protection board without balancing, 8.4 V, current up to 20 A, price $0.83 — link.
I've bought a lot of these, though I could probably say the same about most of the items here. I buy them for other people, but some pass through my hands.

5S protection board, continuous current 15 A, peak current 50–60 A, 21 V. It costs $1.90, but shipping is extra, so buying just one isn't worthwhile — link.

Recommended


Another 5S protection and balancing board, current up to 100 A, voltage 21 V. It costs $3.59; shipping is extra, but inexpensive — link.
At this store, when you order different items, the shipping costs aren't added together; they only go up a little. So it's worth buying several different items. They also have coupons.

Recommended.


Battery charge indicators for different voltages — link.
I reviewed these indicators before and buy them very often.

Definitely recommended.


2S protection board (8.4 V), current up to 3 A, no balancing. It's great for small DIY projects and costs just $0.29 — link.
I received it not long ago; I'll review it.


Another little board from the same store, also 2S (8.4 V), but rated for 5 A—and it's round :)
It costs just $0.44, with free shipping — link.
I received it along with the previous one. I'll review this one too; it looks good. By the way, this board and the previous one have reinforced contacts, with small plates soldered onto the copper.



Another board from a store with free shipping: 1S, up to 3 A. But it costs $1.52 for 10 pieces. I bought it mainly because of the price, just to have some on hand — link.
Like the previous ones, it has reinforced contacts.



This one's from a different store. It's also a 1S board, but rated for up to 15 A. I got it just “for the collection” too; it costs $0.45 — link.
It looks excellent, with six MOSFETs in the power section and reinforced contacts.



3S board with balancing, current up to 10 A. A lot of 5 costs $4.96, but shipping to us is extra — link.
The boards have arrived, but I still haven't found time to test them.


6S, 7S, and 8S balancers. I bought them for a battery analyzer; they cost $1.70–1.83 — link.
They look excellent; I'll definitely review them.


5S balancer. I bought it as an add-on to the ones shown above; it costs $0.90 — link.
No complaints about the appearance either. Overall, the store is pretty good. I recommend it.



Some kind of hybrid charger and step-up converter. I bought it out of curiosity and want to try it as a small UPS. It costs $0.80, but shipping is extra, so buying just one isn't worth it - link.



A power bank board, rated for up to 2 A. It costs just $0.81, but unfortunately shipping is extra, so again, buying just one is expensive - link.




Another power bank. It cost $1, with free shipping, but the seller couldn't ship it in time because of the holidays, so the system automatically closed the order. The seller later wrote to apologize and offered me a coupon - link.
Looks pretty good, and the price is reasonable.



Just some small boards with microUSB connectors for various projects. A lot of 50, priced at $3.61 - link.



A step-down converter with CC/CV mode. A friend was buying one, so I picked one up too, since readers had questions about this converter. So, there'll be a review.
It costs $1.16, with shipping extra - link.



Another converter, and not just one. I bought them more for a review than for actual use, just out of curiosity.

24 V input, 5 V 3 A output, priced at $0.93 - link



An adjustable converter, rated for 1.8 A continuous and up to 3 A maximum. It costs $0.30, with shipping extra, so buying just one isn't worth it - link.



Another adjustable converter, which I again bought out of curiosity. It costs $0.52, with shipping extra - link.
I often mention that shipping costs extra, but I either buy a lot or order different items from the same store, which makes shipping cheaper. I also try to find discount coupons from sellers.




This one's a classic: a small step-up converter. I even modified one into a SEPIC converter once. A lot of 20, priced at $10.22 - link.
I wasn't buying this one for myself; I think the seller also offers them individually.



A 20 A step-down converter. I bought it, but it's still on the way. It looks nice, which is probably why I bought it. It costs $5.91, with shipping extra, but if you buy several different items from the seller, the shipping charges aren't added together - link.



I also picked up a 15 A step-up converter for a review. I've tended to avoid these, so I decided to fill that gap. It costs $5.54, link.



A converter with a 5 V, 3 A output. Because of a mistake by the seller, I'm waiting for a second package. It costs $0.68, link.



The second version of the same converter, with a different inductor design. I ordered it just out of curiosity, from another seller. It costs $0.68 - link.



A small, handy USB tester. It costs $6.08, link.
By the way, these testers were extra prizes in the blog's pre-New Year giveaway.



That's all for now. And again, this isn't even half of what I order for myself, so, as they say, to be continued.
