My power bank has been working great for a year and a half and I use it regularly, but it suddenly doesn’t want to receive a charge. When I plug it in, the first of the four green lights flashes, and it keeps flashing that one light until I unplug it. It does not appear to be charging at all. I have tried a variety of different cables (USB C and micro-usb), so I don’t think it’s the cable that is the issue.
Model: AUKEY PB-Y23 20000mAh Universal Power Bank
Any advice on how I can get it working again? Thanks in advance,
