Today I plugged my 2000 mAh PCC at 4 PM. It's 2:14 AM and the light is still on. 10 hours seems a little too much to still be charging. I unplugged it and plugged it again several timess but the red light is still on. I know for sure the outlet works, changed cables and it's still charging. The night before that it charged perfectly well and the green light was on, and charged my batts just fine.
