Ensure the magnetic connection is stable. If the watch or bracelet does not have a magnetic connector, the metal contact instability may prevent charging.
5. Operating Instructions
Once the cable is securely connected to both the power source and the smartwatch, the charging process will begin automatically. Most smartwatches will display a charging indicator, such as a battery icon with a lightning bolt or a percentage increase, to confirm that charging is in progress.
No further action is required during the charging process. Disconnect the cable once your smartwatch is fully charged or when you need to use it.
6. Maintenance
To ensure the longevity and optimal performance of your charging cable, please observe the following maintenance guidelines:
- Keep Clean: Regularly wipe the magnetic contacts on the cable with a soft, dry cloth to remove any dust or debris that may interfere with the connection.
- Avoid Bending: Do not excessively bend or crimp the cable, especially near the connectors, as this can damage the internal wires.
- Proper Storage: When not in use, store the cable in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tangling the cable.
- Handle with Care: Always pull from the plug, not the cable itself, when disconnecting from a power source or smartwatch.
While the cable is designed to be compatible with IP67 waterproof smartwatches, the cable itself is not rated for immersion. Keep the cable dry to prevent damage.
7. Troubleshooting
If you encounter issues while using your charging cable, consider the following troubleshooting steps:
- Cable Not Charging:
- Ensure both the USB-A end and the magnetic end are securely connected.
- Try a different USB power source (e.g., another USB port on your computer, a different wall adapter).
- Verify that your smartwatch has a magnetic charging interface. This cable is specifically designed for smartwatches with magnetic contacts. If your watch uses a different charging method (e.g., 2-pin, clip-on, or USB-C directly), this cable will not be compatible.
- Clean the charging contacts on both the cable and the smartwatch to ensure good conductivity.
- Unstable Magnetic Connection:
- Ensure there is no debris or foreign material between the cable's magnetic head and the smartwatch's charging port.
- Confirm that the smartwatch's magnetic charging area is intact and not damaged.
If the issue persists after attempting these steps, please refer to the support information provided in Section 9.
