    Powerful DIY power bank.
    This compact board has all the electronic you need to build a power bank. Just add the batteries on it and voila. DIY power bank with many good features like: LCD with back light, (charge %, in, out) display indicators, two USB outputs (1 & 2 A), one micro USB input, battery current and charge protection, simultaneous charge and discharge, button for on/off and a simple LED torch (hold it to ON OFF, two click for LED switch), auto power off after a while without use. I did it myself, a two battery power bank, as you can see in the pictures. The 18650 type batteries I've got from an old laptop battery block, but one can buy them at Gearbest, if not used to disassemble old things. The most difficult part is the coverage, but I found TIC-TAC candy's box fits the board and for the rest I used isolation tape.I really appreciated this small great board and for sure I will order more. Highly recommend it for anyone with basic electronic skills.

    works fine
    Works great, automatically turns off when the battery reaches 3V and stops charging it at 4.2V.It will not charge and output power at the same time.The led is a bit useless.
