Anker Powercore 3 Elite Stopped Working

Powercore 3 has worked flawlessly for a year. Now it won’t charge any devices. Only time it comes alive is when I plug it in, the lights all light up
One at a time all the way around clockwise then this pattern repeats once again. Then all the lights stay on except the one to the left of top center which blinks intermittently. Once before this happens and I was able to reset it by connecting the loop usb a to c but this time it has no effect or somehow I’m doing it wrong. Any insight would be greatly appreciated

Interesting is, that you were able to do a reset
and this helped.
You could ask the support, may be they have an ideal
