6. Compatibility

The BESTEK Universal Travel Adapter is compatible with a wide range of low-to-medium wattage electronic devices. However, it is crucial to understand its limitations:

• Compatible Devices (under 250W): Cellphones, Cameras, Power Banks, Laptops, Tablets, Bluetooth speakers, etc.
• NOT Compatible Devices: Hair dryers, hair straighteners, curling irons, coffee machines, electric kettles, electric toothbrushes (some models), or any appliance with a heating element or motor that exceeds 250W. These devices require direct voltage compatibility or a higher wattage converter.

7. Maintenance

To ensure the longevity and optimal performance of your BESTEK Universal Travel Adapter:

• Cleaning: Disconnect the adapter from the power source before cleaning. Use a dry, soft cloth to wipe the surface. Do not use liquid cleaners or abrasive materials.
• Storage: Store the adapter and its accessories in a cool, dry place away from direct sunlight and moisture. Keeping it in its original packaging or a protective bag can prevent damage during travel.
• Handling: Avoid dropping the unit or subjecting it to strong impacts. Do not attempt to disassemble or repair the unit yourself.

8. Troubleshooting

If you encounter issues with your BESTEK Universal Travel Adapter, try the following:

• No Power/LED Off: Ensure the power cable is securely connected to both the converter and the wall outlet. Check that the power switch on the unit is in the 'ON' position. Verify the wall outlet is functional.
• Device Not Charging: Confirm that your device is compatible with the converter (under 250W, not a heating appliance). Check the device's charging cable for damage. Ensure the total wattage of all connected devices does not exceed 250W.
• Unusual Noise: Some users may notice a slight fan noise during operation. This is normal as the internal fan helps dissipate heat, especially when multiple devices are connected or under heavy load. If the noise is excessively loud or accompanied by other issues, discontinue use and contact support.
• Overload Protection: If the converter automatically shuts off, it may be due to an overload. Disconnect some devices, turn the unit off and then on again.
