TP4056 USB-C Panel Mount – Flush USB Type-C Charging Port for DIY Li-Ion Battery Projects

The TP4056 USB-C Panel Mount is designed for projects that need a convenient external USB Type-C charging connection. Instead of leaving a charging connector buried inside an enclosure, the panel-mount arrangement allows the charging port to be positioned through a wall or custom case for easier access.

It is suitable for projects based on the widely used TP4056 single-cell lithium battery charging system. Typical TP4056 Type-C charging modules accept approximately 5V USB input and provide a regulated 4.2V charging voltage for a single-cell Li-ion/LiPo battery. Many common protected versions support charging at up to 1A.

How to Use

1. Install the panel-mount USB-C interface into the prepared opening of your enclosure.
2. Secure the panel mount using the appropriate mounting method for your enclosure design.
3. Connect the charging section to the appropriate TP4056 input and battery connections.
4. Connect a compatible single-cell Li-ion/LiPo battery according to the charging module's polarity markings.
5. Connect a 5V USB-C power source.
6. Check the charging-status indicator if your TP4056 module provides LED indicators.
7. Verify the battery voltage and charging behavior before closing the enclosure permanently.

Important Notes

• This product is intended for single-cell Li-ion/LiPo battery charging applications when used with a suitable TP4056 charging circuit.
• Do not use a TP4056 charger designed for a single cell to charge a 2S or higher battery pack.
• Use the correct battery polarity; reverse battery connection can damage charging electronics.
• The actual charging current depends on the TP4056 board configuration and programming resistor.
• A typical TP4056 module charges to approximately 4.2V and should be used only with compatible rechargeable lithium cells.
• Do not assume every TP4056 board includes battery protection; protection circuitry varies between module versions.
• Provide adequate ventilation and avoid enclosing a charging circuit where heat cannot dissipate.
• Use a suitable 5V USB power source and appropriate cable.
• Never leave damaged, swollen, or otherwise unsafe lithium batteries connected to a charger.
