Features:
The input end has a Type-C USB socket, which can be used directly with a mobile phone charger to charge the lithium battery, and the input voltage wiring solder joints are still retained, which is very convenient for DIY.

Parameters:
Input voltage: 5V
Charging cut-off voltage: 4.2V ±1%
Maximum charging current: 1000mA
Battery over-discharge protection voltage: 2.5V
Battery over-current protection current: 3A
Board size: 26mm*17mm

How to use:

Note:
1. When the battery is connected for the first time, there may be no voltage output between OUT+ and OUT-. At this time, connect a 5V voltage to charge and the protection circuit can be activated. If the battery is short-circuited from B+ B- and then connected, it also needs to be charged to activate the protection circuit.

2. When using a mobile phone charger for input, please note that the charger must be able to output 1A or more, otherwise the module may not charge normally.

Connection method:
The Type-C USB socket and the + - pads next to it are the power input terminals, connected to 5V voltage;
B+ connects to the positive pole of the lithium battery;
B- connects to the negative pole of the lithium battery;
OUT+ and OUT- connect to the load, such as the positive and negative poles of the mobile booster board or other loads;
Connect the battery to B+ B-, insert the mobile phone charger into the USB socket, the red light is on for charging, and the green light is on for full.

Package Included:
10PCS TP4056 5V 1A Type-C USB Charging Module Charging Board
