A:Answer If possible, please try the following steps to see if the issue persists:
- Plug both ends of the USB-C cable into the input and output port of the battery at the same time for 3-5 seconds.
- Fully recharge and use up the battery again to see if everything works properly.
- Try a different wall charger and cable.
