Type-C Charging Module TP4056 Set of 2 Lithium Battery Charger Module Input Voltage: 4.5V-5V Maximum Charging Current: 1000mA Charge Termination Voltage: 4.2V ± 1% Battery Over-Discharge Protection Voltage: 2.5V/3A Board Size: 28 x 17 x 4mm Made in China When connecting the battery for the first time, there may be no voltage output on the OUT terminal. You need to connect 5V to the power input and charge it slightly to activate the protection circuit. I have confirmed that the LED lights up when connecting power to Type C and connecting it to this module. However, I have not performed any further checks. Please understand the above before purchasing.
