5. Safety Information & Important Notes
Important Note: This device is NOT a voltage converter. It is suitable only for dual-voltage or global devices with an input voltage range of 100-250V. It does not perform voltage conversion or frequency modification. Using it with devices that are not dual-voltage or do not match the local voltage can damage your device or the adapter.
- Always check the voltage requirements of your devices before plugging them into the adapter.
- Do not exceed the maximum power rating of the adapter (e.g., 1000W at 100V, 2500W at 250V).
- Avoid using the adapter in wet environments.
- Keep out of reach of children.


6. Maintenance
6.1 Fuse Replacement
The adapter is equipped with two 10A overload fuses. If the adapter stops functioning, one of the fuses may have blown. A spare fuse is included for replacement.
- Locate the fuse compartment on the adapter.
- Carefully open the compartment.
- Remove the blown fuse and replace it with the spare 10A fuse.
- Close the compartment securely.
6.2 Cleaning
To clean the adapter, disconnect it from the power outlet and all devices. Wipe the exterior with a dry, soft cloth. Do not use liquid cleaners or immerse the adapter in water.
7. Troubleshooting
- Adapter not powering on:
- Ensure the adapter is fully plugged into the wall outlet.
- Check if the fuse needs replacement (refer to Section 6.1).
- Device not charging:
- Verify that your device is properly connected to the adapter.
- Confirm that your device is dual-voltage and compatible with the local power supply.
- Check if the charging cable is functional.
- Ensure the total power draw does not exceed the adapter's maximum rating.
- Slow charging:
- Ensure you are using a high-quality charging cable.
- If multiple devices are connected, the power output may be distributed, leading to slower charging for individual devices.
- For optimal fast charging, use a single USB-C port for high-power devices.
