1. Introduction
This manual provides instructions for the USB-C Magnetic Charger Adapter, designed as a replacement or spare charging accessory for POLVCDG X6 and other compatible bone conduction headphones. This adapter features a strong N52 magnetic connection for easy and instant charging, a universal Type-C input, and built-in safety protections to ensure the longevity of your headphone battery.

2. Setup
- Connect to Power Source: Insert the USB-C end of the charger adapter into a compatible USB-C power adapter (not included) or a USB-C port on a computer or power bank.
- Prepare Headphones: Ensure your bone conduction headphones are clean around the charging port.
- Magnetic Connection: Bring the magnetic charging end of the adapter close to the four-pin charging port on your bone conduction headphones. The N52 magnetic force will automatically align and securely attach the adapter to the headphones.
- Verify Connection: A built-in power indicator light on the adapter will illuminate, confirming that the connection is established and charging has begun.


3. Operating Instructions
Once connected, the adapter provides a stable 5V-1A output, optimized to protect your headphone battery during charging. The built-in power indicator light allows you to easily monitor the charging status, even in low-light conditions.

4. Maintenance
- Keep the magnetic contacts and the USB-C port clean and free from dust or debris.
- Avoid exposing the adapter to extreme temperatures or moisture.
- Do not bend or apply excessive force to the cable or connectors.
- Store the adapter in a dry, safe place when not in use. The integrated keyhole allows for easy attachment to keychains, preventing loss.

5. Troubleshooting
- No Charging Indicator:
- Ensure the USB-C end is fully inserted into a working power source.
- Check that the magnetic end is correctly aligned and securely attached to the headphone's charging port.
- Try a different USB-C power adapter or port.
- Slow Charging:
- Ensure your power source provides sufficient output (e.g., 5V-1A).
- Clean the magnetic contacts on both the adapter and the headphones.
- Adapter feels warm: It is normal for the adapter to feel slightly warm during charging. If it becomes excessively hot, disconnect it immediately and contact support.
The adapter includes built-in protections against overvoltage, short circuit, over temperature, overcurrent, and overload to safeguard your headphones.
