Diymore 5PCS TP4056 Type-C USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions

Great price and works as expected.

If charges the batteries as expected! It's acting funny with this tiny battery, flashing both blue and red lights when the battery is charged/closed to charged, but I believe that the problem is the battery that don't charge on a stable tension when it is close to charged! With the other battery it works as expected, turn blue when it is charged!

Great little boards for hobbyists ez to work with

I used this with a 3.7v 1c lipo and powered a raspberry pi with it - it provided enough power to the pi along with connected devices. I greatly recommend this to anyone trying to make project that requires a rechargeable battery rather then trying to make this charger yourself. It also has a led which indicates if it’s charging or full. Also has some easy solder points

Works well but very sensitive. They will charge. Batteries with a USB A to C cable. NO USB PD support. Very sensitive to voltage on wrong pins or lack of voltage on pins. A few of mine have died.

As described as well as a very pleasant follow up message from the seller.

I only needed one of them for my needs. However, I had to buy 5 of them, but the price is great. No issues so far. I was able to charge my 18650 battery with this controller using an old solar panel from the LED motion detection panel (the solar panel produces about 10 VDC in full sunlight).

I tried two and both were defective. They appear to charge the battery but get dangerously hot doing so, and they shut off and started smoking with a 0.5A load connected to the output. Also these are not standards compliant USB C, they have a USB C input but don't work with C to C cables or C power supplies, only A to C.
