From Makers Electronics's description
TP4056 Micro USB Lithium Battery Charger Module 5V 1A The TP4056 Micro USB Lithium Battery Charger Module (5V 1A) is a compact and efficient charging solution designed specifically for single-cell 3.7V lithium-ion and lithium-polymer batteries. Built around the TP4056 charging IC, this module offers a complete constant-current/constant-voltage linear charging system with high accuracy and reliability, making it ideal for DIY electronics, portable power systems, and embedded battery-powered devices. The module is powered via a standard Micro USB port or through soldered input pins, allowing flexible integration with various power sources such as USB adapters, power banks, or solar panels. It supports a charging current of up to 1A, which is set by the onboard configuration and is suitable for charging most common Li-ion batteries with capacities ranging from 500mAh to 2000mAh and beyond. Safety is a key feature of the TP4056 module. It includes built-in overcharge protection, over-discharge protection, short circuit protection, and overcurrent protection, thanks to the inclusion of protection ICs like DW01 and dual MOSFETs. These features prevent battery damage and ensure reliable operation during charging and discharging cycles. The module also features onboard LED indicators that provide real-time feedback: a red LED lights up during charging, and a blue (or green) LED indicates when charging is complete. The small size and straightforward design make it an excellent choice for beginners and hobbyists working on compact battery-powered devices.
