This 1pcs TP4056 Lithium Battery Charging Board is a dual-function charger module, featuring Type-c USB interface, 5V 1A charging current, and built-in protection functions, specifically designed for 18650 lithium batteries. It integrates both charging and protection capabilities, making it a practical and reliable power solution for DIY projects, portable devices, and Arduino-based battery-powered applications.
At the core of the module is the TP4056 lithium battery charging management chip, a high-performance chip that supports constant-current and constant-voltage charging modes. It provides a stable 5V input voltage via the Type-c USB interface and delivers a charging current of 1A, ensuring fast and efficient charging for 18650 lithium batteries—significantly reducing charging time compared to low-current chargers.
The module features dual core functions: charging and battery protection. On the charging side, it automatically detects the battery voltage and switches between constant-current (CC) and constant-voltage (CV) modes to ensure safe and full charging. When the battery is fully charged, the module automatically stops charging, preventing overcharging and extending the battery’s service life.
Equipped with comprehensive protection functions, the TP4056 module effectively safeguards both the battery and the module itself. It includes overcharging protection, over-discharging protection, over-current protection, and short-circuit protection. These protections prevent damage caused by abnormal working conditions, such as battery overcharge, excessive discharge, short circuits, or current overloads, ensuring safe and stable operation.
The module adopts a Type-c USB interface, which is reversible and widely compatible with modern USB chargers, power banks, and computer USB ports. Its compact design allows for easy integration into portable devices, DIY kits, and Arduino projects that require a compact power supply solution. It also features clear pin labeling (VCC, GND, BAT, OUT) for simple wiring, making it easy to connect to 18650 batteries and load devices.
Designed for 18650 lithium batteries (the most commonly used rechargeable lithium battery in DIY projects), the module is fully compatible with 3.7V 18650 batteries of various capacities. It supports both charging and discharging functions, allowing the battery to be charged via the Type-c interface and power external devices (such as Arduino boards, sensors, and LEDs) through the output terminal.
This TP4056 charging module is widely used in Arduino projects, portable electronics, DIY power banks, smart wearables, and battery-powered devices. It is easy to install and use, requiring no complex configuration, making it suitable for both beginners and professional developers. With its Type-c interface, 1A fast charging, dual functions, and comprehensive protection, it is a cost-effective and reliable choice for powering your 18650 lithium battery-based projects.
