Mine stopped working altogether.  No sign of life even with the power plugged in.  I had tried  the "reset" steps I found on the internet (holding big button down then plugging into power) and also a USB cable still with no lights or signs of life.

I disassembled it, unplugged the battery, plugged it into power without the battery and it worked.  Then I unplugged the power, plugged the battery back in, and plugged it back into power.  It fully charged in a couple of hours and the battery measured 12.58v (with no load) after it was fully charged.  It works fine now.

I think the battery is probably three 18650's in series with a protection circuit.
