TP4056 USB Type-C 5V 1A Li-ion Battery Charger Module with Protection – 3.7V 1S

TP4056 USB Type-C 5V 1A Lithium Battery Charger Module

Charge compatible single-cell 3.7V lithium-ion and lithium-polymer batteries using the TP4056 USB Type-C charging module. Designed for DIY electronics, portable devices and rechargeable battery projects, this compact board accepts a 5V input and uses a constant-current/constant-voltage (CC/CV) charging method to charge a standard single-cell lithium battery to approximately 4.2V.

The charging current can be configured up to 1A, depending on the module's current-setting resistor, input supply and thermal conditions.

Key Features

• USB Type-C Input: Convenient 5V DC input using a compatible USB Type-C cable and power supply.

• Single-Cell Charging: Designed for compatible 1S, 3.7V nominal Li-ion or Li-Po batteries.

• Up to 1A Charging: The TP4056 controller supports programmable charging current up to 1A; actual current depends on the board configuration and operating temperature.

• CC/CV Charging: Uses constant-current and constant-voltage charging, with a nominal 4.2V charge regulation voltage for standard Li-ion cells.

• Charging Status Indicators: Many versions use onboard LEDs to indicate charging and charge completion. LED colors and behavior depend on the actual board.

• Optional Integrated Battery Protection: Protection-equipped versions may include a DW01A-family protection IC and dual MOSFETs to help protect against specified overcharge, over-discharge, overcurrent and short-circuit conditions.

• Compact DIY Design: Suitable for integration into compatible rechargeable electronics and battery-powered projects.

Typical Applications

• Single-cell 18650 lithium-ion battery projects

Important Usage and Safety Notes

1. Use only with a compatible single-cell lithium-ion or lithium-polymer battery. Do not use this module to charge a multi-cell series battery pack.

2. Supply the module with the specified 5V input. Do not connect a higher voltage to the USB input.

3. Confirm the correct battery polarity and terminal labels before connecting the battery.

4. Do not assume the module can safely charge every battery at 1A. Check the battery manufacturer's recommended charging current.

5. The TP4056 is a linear charger and can become warm during charging. Adequate thermal management and suitable operating conditions are important.

6. A charging controller is not the same as a battery protection circuit. Confirm that the specific module includes protection before relying on overcharge, over-discharge, overcurrent or short-circuit protection.

7. Do not leave lithium batteries charging unattended in unsafe conditions. Stop using damaged, swollen or overheating cells.
