Maintenance and Care

• Cleaning: Use a soft, dry cloth to clean the surface of the power bank. Do not use harsh chemicals or abrasive materials.

• Avoid Drops: Protect the device from drops and impacts, which can damage internal components.

Troubleshooting

Common Issues and Solutions

• Power Bank Not Charging:
  

  Ensure the charging cable is securely connected to both the power bank's input port and the wall charger. Verify that the wall charger is functioning correctly and provides sufficient power (e.g., 18W or 30W for fast charging).

• Device Not Charging from Power Bank:
  

  Check if the power bank has sufficient charge. Ensure the charging cable connecting your device to the power bank is not damaged and is securely connected. Try a different output port or cable. If charging a low-power device, ensure low-current mode is activated.

• Flashlight Not Working:
  

  Ensure you are long-pressing the light switch button for 3 seconds to toggle the flashlight on/off. If the power bank's battery is critically low, the flashlight function may be disabled.

• Slow Charging:
  

  Ensure both the power bank and your device support fast charging protocols (PD, QC). Use a compatible fast-charging cable. The charging speed can also be affected by the number of devices being charged simultaneously and the remaining battery level of the power bank.
