TP4056 Lithium Battery Charger 1A Type C Micro USB 4.5V 5V

The TP4056 Lithium Battery Charger Module is a compact, efficient 1A charging solution designed for lithium battery projects. From Choice, this small yet capable charger offers a safe, auto-regulating charge with a 4.2V cutoff and over-discharge protection. Its slim footprint (28 x 17 x 4 mm) fits neatly into tight spaces while delivering reliable charging performance via a Type-C input connection. The module supports a wide input range of 4.5V–5V and can deliver up to 1000mA of charging current, helping you charge Li-ion or Li-poly batteries quickly and safely. It includes multiple protection features to guard your cells from overcharging and over-discharging, and its intelligent current control ensures optimal charging safety during use. A blue indicator light shows power availability, while a red light indicates charging status, giving you clear feedback at a glance.

Benefits & Tips

• Fast, safe charging for lithium batteries (Li-ion/Li-poly) with a 4.2V cutoff and over-discharge protection at 2.5V/3A.
• Compact, flexible design—small board size fits into battery packs, portable gadgets, and microcontroller projects while maintaining reliable charging performance.
• Easy usage tips: when using the first connection, apply 5V to the input to activate the protection circuit. If powered by a USB charger, ensure it can output >1A for proper charging, otherwise charging may be slow or fail to start. Connect B+ to the battery positive, B- to the battery negative; OUT+ and OUT- go to the load. A blue LED means power is present; a red LED indicates charging (steady when complete). If a load is connected, the red LED stays on as long as power is available.
