Totally works.

No Balance leads. Unsafe.
The entire point of a multi-cell BMS is to have balance leads to charge each cell evenly. You should never charge multiple Li-Ion batteries in series without balance leads. t's not if they will, it's they will, it's when they will go Chernobyl on you. Don't buy these. I'm returning mine. unsafe.

Worked perfectly to charge my 3S1P battery pack
This is a review of a 2x USB-C 3S 1A 18650 battery charger board.I've been looking for a way to charge a 3S1P battery (in my case, a battery for an Elecraft KX2) which would let me leave my bulky brick charger at home. Now I'm able to carry this tiny board with me all the time and use it with the USB charger I always have with me - a huge win. I ended up sticking it in transparent heat shrink tubing to protect it while still being able to see the status LEDs, and I soldered on a pigtail which matches the barrel plug of my battery.I'm deducting one star because despite having a USB-C input, it can't use a USB-C power source. It doesn't seem to have a 5V PD trigger, so you end up needing to feed it with a USB-A to USB-C cable (or I suppose anything else that's only 5V).Pros:* VERY small* Charged my battery successfully* Put out a nice, slow charge to not stress out the battery* Able to detect a full battery (i.e. it doesn't keep pushing current after the battery is charged)Cons:* Requires a 5V source (i.e. you can't use a USB-C to USB-C cable, but you can use USB-A to USB-C)

Charging cable must be USBA to USB-C or it doesn’t work.
Charge Cable does not work if it is USB-C to USB-C.Charge Cable works properly if it is USBA to USB-C.

Nothing happens.
3s 4a version, pack of 2. Connected to 3s 18650 and plugged in to a dc5v 5.1a power supply. Nothing. Neither one will turn on at all. Meter reads no voltage or amperage passing through the device.

Over charges
Charges past 8.45v.... that's where I stopped it. Tried twice.Not a 2s charger. Works if you are gonna watch the voltage, but it's voltage target is to high to be left alone.Also the single mosfet gets very hot above 2amps

Does not have low-short battery protection, uses CN3304 4-cell charging chip
Used this for a home project with cheap Li Ion battery chargers. With the CN3304 chip, there's no easy way to reconfigure it to a different number of cells. You're stuck with 16.8V charging, which is 4 cells at 3.7V nominal per cell. Fine for my application, though I would have preferred 3S rather than 4S. In my case, the extra cost to pay regular price for the 3S module was more than the cost of the extra cell! Includes blue input power LED and red charging LED on board. Very easy to wire up, already has the USB-C connector on board.
