It is in order. - Power supply accessory

I found that charging stops at around 4.10-4.15V too soon (I score 3 out of 5 on this purchase). The charging current was about 700mA. The idle current is 11.5 µA with a battery voltage of 4V. The micro USB connector, which should be an input, outputs 5V when the board is connected to the battery. Update 08/27/2018: I bought it again because I was looking for a small board with a 5V Li-Ion amplifier and Li-Ion charging function. I couldn't find any in this size.

Pros

Easy setup

Cons

Everything OK
