TP4056 CHARGING BOARD

Description

The TP4056 Charging Board is a compact single-cell lithium-ion/lithium-polymer battery charger module designed for safely charging 3.7V Li-Ion and Li-Po batteries. Based on the TP4056 charging IC, it uses a constant-current/constant-voltage (CC/CV) charging method to provide efficient and reliable battery charging from a 5V power source. It is widely used in power banks, portable electronics, IoT devices, DIY projects, and battery-powered systems.
