- Connect one end of the cable to your device and the other end to one of the power bank's USB-A or USB-C output ports.
- The power bank will automatically detect the connected device and begin charging. The LED display will show "OUT" when discharging.
Wireless Charging
To charge your Qi-compatible device wirelessly:
- Ensure your device is Qi-compatible.
- Place your device directly onto the wireless charging pad located on the power bank.
- Adjust the device's position to ensure it is centered on the charging pad for optimal contact.

Note: This power bank does not support magnetic charging. For best wireless charging performance, remove any thick phone cases.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your power bank:
- Cleaning: Use a dry, soft cloth to clean the surface of the power bank. Avoid liquid cleaners or abrasive materials.
- Storage: Store the power bank in a cool, dry place, away from direct sunlight and extreme temperatures.
- Handling: Avoid dropping the power bank or subjecting it to strong impacts.
- Disassembly: Do not attempt to disassemble, repair, or modify the power bank yourself. This can void the warranty and pose safety risks.
- Charging Cycle: For optimal battery health, fully charge and discharge the power bank at least once every three months if not in regular use.
Troubleshooting
If you encounter issues with your Charmast power bank, refer to the following common solutions:
- Power Bank Not Charging:
Ensure the charging cable is securely connected to both the power bank's input port and the power adapter. Try using a different USB cable and a different power adapter to rule out faulty accessories. Verify the power adapter is functioning correctly. - 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 functional and securely connected. Confirm your device is compatible with the power bank's output ports (USB-A, USB-C). - Slow Charging:
For fast charging, ensure both your device and the charging cable support PD or QC 3.0 protocols. Using standard cables or non-fast charging compatible devices will result in slower charging speeds. - Wireless Charging Not Working:
Verify that your device supports Qi wireless charging. Ensure the device is placed centrally on the power bank's wireless charging pad. Remove any thick phone cases or metallic objects between the device and the power bank that might interfere with charging. - LED Display Not Working:
If the display is unresponsive, try charging the power bank for a short period. If the issue persists, contact customer support.
