Yesterday after work, I tried plugging my phone into the device to charge, but noticed that no charge was being given. Upon looking at the charger, the lights were blinking as if the battery was plugged into a wall and being charged (to try and give a visual, the lights were lighting up sequentially in the circle, then the last light would blink, indicating that it was almost charged). I didn't know what to do, so I plugged the battery into the wall to see if anything would change. Eventually, the lights on the battery stopped blinking, so I assumed it was fully charged.
Now that I try to use the battery today, the lights do not light up at all, whether I press the button, plug it into a phone, or even to the wall. I've tried using different cables, different ports, continuously pressing the button on the battery, and the lights do not show, nor does the battery provide any power to my phone.
Is there a way to troubleshoot this device, or is it broken? Thanks for the help!
