Hi there. Just got my Anker 10000 and it worked, as expected, for just a few charges. Now, when I plug my Powercore into a wall charger, it shows all 4 blue lights as fully charged. When I plug it into my phone or computer or a speaker, nothing happens. It shows no charging.
- I’ve tried several power cords.
- I pushed the button on the side?
- I tried 3 different devices.
What am I missing??
