Adjustable current lithium battery charging module tp4056x

Overview

tp4056x is used for charging small-capacity lithium batteries. It supports up to 1a current switching by switching different gears. tp4056x has battery reverse connection protection.
You can realize your own gear design by changing the resistor.

Due to the low efficiency of this chip, it is not recommended to use too high a current because it will generate heat. Very large, originally designed for charging small-capacity batteries, so it is not recommended to charge for 1a for a long time
