TP4056 Type-C Li-ion Battery Charging Module – 1A Charger

The TP4056 Type-C Li-ion Battery Charging Module is a compact charging solution designed for single-cell 3.7V lithium-ion and lithium-polymer batteries. Based on the TP4056 charging IC, it utilizes a constant-current/constant-voltage (CC/CV) charging algorithm to ensure safe and efficient battery charging. The module features a USB Type-C input, onboard charging status indicators, and a default charging current of approximately 1A, which can be adjusted through an onboard resistor. Available in versions with battery protection circuitry, it is suitable for portable electronics, DIY battery packs, IoT devices, and rechargeable embedded systems.
