Mini USB Battery Charger TP4056 Module (5V Micro USB, 1A Li-Ion/Li-Po Charger with Protection)

The Mini USB Battery Charger TP4056 Module is a compact charging board designed for safely charging single-cell 3.7V lithium-ion and lithium-polymer batteries. Based on the TP4056 linear charging IC, it uses a constant current/constant voltage (CC/CV) charging algorithm to ensure efficient and reliable battery charging. Powered through a 5V Micro USB input, the module features onboard charging and full-charge status LEDs, making it ideal for DIY power banks, portable electronics, IoT devices, rechargeable battery packs, and embedded systems. Selected module variants also include overcharge, over-discharge, overcurrent, and short-circuit protection.
