The charger adopts TP4056X lithium battery charging IC, which guarantees you quick and safe charging, and also you can easily switch between 3 output currents (the default output current is 50mA) by selecting different bonding pads on the back. The thermal feedback inside the TP4056X can automatically adjust the charging current to limit the chip temperature under high power operation or high ambient temperature conditions.
Plug this charger into power source via its Type-C port, the LED on the charger will flash when no battery is not connected; keep on when charging and go off when the battery is fully charged. So, this LED will consume nothing of your battery.
