5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the charger. Do not use liquid cleaners or aerosols.
- Storage: When not in use, ensure the retractable cable is fully retracted to prevent damage and keep your car tidy. Store the charger in a cool, dry place away from direct sunlight.
- Cable Care: Avoid excessive force when extending or retracting the cable. Do not yank the cable or allow it to snap back forcefully, as this can damage the retraction mechanism.
- Temperature: Do not expose the charger to extreme temperatures.
6. Troubleshooting
- Charger Not Powering On:
- Ensure the car charger is fully inserted into the 12V power outlet.
- Check if the vehicle's power outlet is functioning correctly (e.g., test with another device).
- Verify the vehicle's ignition is on, as some outlets only receive power when the engine is running.
- Device Not Charging:
- Confirm that your device is compatible with USB-C charging.
- Ensure the cable is securely connected to both the charger and your device.
- If using the additional USB-C port, try a different cable to rule out cable malfunction.
- Restart your device.
- Slow Charging:
- Ensure your device supports fast charging via USB-C Power Delivery.
- Charging multiple devices simultaneously may distribute power, potentially reducing individual charging speeds.
- Check the cable for any damage or wear.
- Cable Not Retracting/Extending Smoothly:
- Avoid pulling the cable at an extreme angle. Pull directly outwards.
- Ensure there are no obstructions preventing the cable from moving freely.
- If the issue persists, contact customer support.
