Maintenance
- Keep the charger clean and dry. Use a soft, dry cloth to wipe the surface.
- Avoid exposing the charger to extreme temperatures, humidity, or direct sunlight.
- Do not attempt to disassemble or repair the charger yourself. This will void the warranty and may cause damage or injury.
- Store the charger in a cool, dry place when not in use.
Troubleshooting
If you encounter issues with your HyperJuice 100W GaN Travel Charger, please refer to the following common solutions:
- No Power Output:
- Ensure the charger is securely plugged into a working wall outlet.
- Verify that the correct regional adapter is firmly attached to the charger unit.
- Check if the power outlet itself is functional by plugging in another device.
- Slow Charging:
- Confirm that your device and cable support fast charging protocols (PD 3.0, PPS, QC 2.0+/3.1).
- Ensure you are using a USB-C port for high-power devices like laptops, as USB-A ports have lower output.
- If multiple devices are connected, the power is distributed. Disconnecting less critical devices may increase charging speed for primary devices.
- Device Not Recognized:
- Try a different charging cable.
- Connect the device to a different port on the charger.
- Restart your device.
- Overheating:
- While the charger has optimized thermal management, ensure it is used in a well-ventilated area and not covered.
- If the charger feels excessively hot, disconnect it immediately and allow it to cool down before reuse.
