TP4056 Type-C Lithium Battery Charging Module

GST

The TP4056 Type C Charging Module is a compact charging module designed for charging 3.7V lithium-ion batteries such as 18650 Li-ion Battery using a USB Type-C input.

The TP4056 Type-C Charging Module is based on the TP4056 charging IC, designed specifically for single-cell lithium-ion and lithium-polymer batteries.

It provides constant-current / constant-voltage (CC/CV) charging with built-in charging management and status indication LEDs.

Most versions also include:

Overcharge protection
Over-discharge protection
Short-circuit protection

The module is commonly used in DIY power banks, portable electronics, robotics, and battery-powered IoT projects.
