Unable to output USB power

We sincerely apologise for the inconvenience caused. Please follow the troubleshooting steps below:
If you could send us a photo or video showing the issue, we’ll be able to assist you more quickly.
1. Please check whether the battery is sufficiently charged.
2. Is the LED indicator on the USB output button illuminated?
3. If the USB output port fails to power your device, please let us know the device’s name, model number, and power rating (in watts).
4. Also, please check the portable power station’s LCD display for any warning symbols or error messages.
5. After disconnecting your device from the USB output port, reset the portable power station: press and hold the DISPLAY button for 10 seconds until the screen briefly shows “8888”, then returns to the normal interface — this confirms a successful reset.
6. Please verify whether your device charges correctly using its original charging cable.
7. Finally, check whether the USB output port can successfully power other devices.
