Great Li-Ion Battery Charger
I have built these Li-Ion battery charger in over a dozen projects so far. They ranged from 1200 mAh to 40 mAh batteries. To accommodate the different battery capacities, I unsoldered the surface mount resistor that sets the charging current and replaced it with one appropriate to the battery size. These chargers stop the charge reliably at the required 4.2 V, which is important for battery life. At first, having the charge LEDs mounted on the board was a problem, but now I just drill a small hole in the enclosure near the LEDs and put frosted Scotch tape on the inside of the hole. The light shows up even off axis. With a small battery, the "off" drain on the battery is important. These had a drain in the low microamps, which is great. They are a great way to incorporate USB-charged batteries into projects and a great price as well.

Great charging for the price.
it works as advertise.

Great simple project
Super useful for lipo cells re-purposed from old products. Pulled these cells from Temu under cabinet lights to replace 2-AAA/AA alkaline batteries in common devices

Good value
Decent boards for the very low cost, but they only work with A-to-C charging cords, and are a bit cantankerous

Use a non PD charger and a Heat Sink.
These do not work at all with a PD charger. I expected them to charge at the basic slow rate, but they actually don't even turn on with the PD unit. These also get extremely hot during use. I had to add heat sinks to them, after noticing that ones without a heat sink would occasionally stop charging. With the heat sink, they charge as expected.

Great for messing around with electronics
I was getting tired of using disposable batteries for my hobby electronics, so I purchased these along with some lithium batteries to solder onto them. At first I was having some trouble getting them to work, but then I figured out that it won't work if your cord sends more than around 5 volts, so try to make sure you use cords connected to a USB A port since those are limited at that voltage. Super handy being able to just recharge my batteries with USB C, highly recommend.
