I recently purchased this power bank . I had already bought the Anker Power Port 5 previously and I am trying to charge it with this . The circular lights go all the way around, again and again without stopping at the charge level it has inside ( one light ) . After a long time it’s not charging .
I tried a cable charger combo from a Sony smartphone ( with much smaller Watts outage than the Anker ) and that worked once ( the very first charge of the power bank ) and charged it , very slowly but did charge it .
Now for the second charge of the power bank, neither the Power Port 5 , nor the Sony charger are charging it. The same indication , the lights go around but don’t stop at the level of charge inside .
