If the display shows “Device already bound” but you’re unable to connect to the app, please try the following steps:
1. Restart your smartphone.
2. Reset the portable power station.
To reset: Press and hold both the Power button and the USB button simultaneously for 5 seconds. The screen will briefly turn off and then relight, showing the remaining battery percentage — this confirms the reset is complete.
When trying to connect to portable power, it shows 'Device is bound', unable to connect. What should I do?
