TP4056 USB-C 1S 1A Lithium Battery Charger Module with Protection

Description

TP4056 USB-C Charger Module with Protection The TP4056 USB-C Charger Module provides a compact charging solution for a single lithium-ion or LiPo cell. Connect a suitable 5V power source through the USB-C port to charge the battery. The module uses a constant-current and constant-voltage charging method. It charges the battery up to 4.2V and displays the charging status through two onboard LEDs. Key Features Charges one 3.7V lithium-ion or LiPo cell Modern USB-C power input Charging current up to 1A Full-charge voltage of 4.2V Constant-current and constant-voltage charging Overcharge protection Over-discharge protection Overcurrent and short-circuit protection Red and green status indicators Compact size for portable projects Technical Specifications Charging Controller: TP4056 Supported Battery: Single-cell lithium-ion or LiPo Battery Configuration: 1S Nominal Battery Voltage: 3.7V Input Voltage: 4.5V–5.5V DC Recommended Input: 5V DC Maximum Charging Current: 1A Full-Charge Voltage: 4.2V Charging Accuracy: Approximately 1.5% Operating Temperature: -10°C to +85°C Input Connector: USB-C Approximate Size: 25 × 19mm LED Indicators Red LED: Battery charging Green LED: Charging complete Terminal Connections B+: Connect to the battery’s positive terminal. B-: Connect to the battery’s negative terminal. OUT+ or P+: Positive protected output for the load. OUT- or P-: Negative protected output for the load. How to Use Connect the battery to the B+ and B- terminals. Check the battery polarity carefully. Connect the load to OUT+ and OUT-. Supply 5V through the USB-C port. Monitor the onboard LEDs during charging. Disconnect the power after completing the required test or installation. Applications Use this charger module for: Rechargeable 18650 battery projects Single-cell LiPo battery charging DIY power banks Portable electronic devices Robotics projects Arduino battery-powered systems Emergency lights Battery repair projects Package Contents 1 × TP4056 USB-C 1S Charger Module with Protection Important Notes The module supports only one 3.7V lithium cell. Do not connect multiple cells in series. Check the positive and negative terminals before connection. The module does not provide reverse-polarity protection. Select a charging current that matches the battery capacity and specifications. The module may become warm because it uses linear charging. Do not use damaged, swollen, or deeply discharged batteries. Product dimensions may vary slightly between manufacturing batches.
