7. Maintenance

• Cleaning: Disconnect the charger from the power outlet and all devices before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or aerosols.
• Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures.
• Handling: Avoid dropping the charger or subjecting it to strong impacts. Do not attempt to disassemble or modify the charger.

8. Troubleshooting

• Device not charging:
  • Ensure the charger is securely plugged into a working power outlet.
  • Verify that the charging cable is properly connected to both the charger and the device.
  • Try a different cable or port to rule out a faulty cable or port.
  • Ensure your device is compatible with the charger's power output.
• Slow charging:
  • For laptops requiring high power, ensure you are using the USB-C1 port and a PD 100W compatible cable.
  • When multiple devices are connected, the total 120W power is shared. This may result in slower charging for individual devices compared to single-device charging.
  • Ensure your device supports fast charging protocols compatible with the charger.
• Charger pauses briefly when connecting a new device:
  • This is normal behavior. The charger intelligently re-negotiates power distribution to ensure safe and optimal charging for all connected devices.
• Charger feels warm:
  • It is normal for the charger to become warm during operation, especially under heavy load. If it becomes excessively hot or emits smoke/unusual odors, disconnect it immediately and contact customer support.
