Troubleshooting
No Power to Outlets/USB Ports:
- Ensure the power strip is securely plugged into a working wall outlet.
- Check if the master power switch on top of the tower is in the "ON" position.
- Verify that the wall outlet itself is functional by plugging in another device.
- If the "Protected" indicator light is off, the surge protection may have been activated due to an overload or surge. Disconnect all devices, reset the unit (if applicable, by unplugging and replugging), and if the light remains off, the surge protection is no longer active.
Slow USB Charging:
- Ensure your device's charging cable is not damaged and is properly connected.
- The total current for all USB ports is 3A. If multiple devices are connected, the charging speed may be reduced. Try charging fewer devices simultaneously.
- Some devices require higher charging currents than others. Check your device's specifications.
Maintenance
- Disconnect the power strip from the wall outlet before cleaning.
- Wipe the exterior with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Avoid blocking the ventilation openings (if any) to prevent overheating.
