K. So, I bought a PSP without a charger about a few days ago. Fair game. I bought a $4 off eBay. Well, for some odd reason, when playing the PSP while plugged into the AC adapter, the psp still drains battery. Slowly, but still drains. Is this normal for psps? Or is it just that my psp charger sucks? 'Cause I left my psp on one time, with the AC charger plugged in, and set it down. The screen turned off, but I came back a few hours later. I checked my battery at it was at 22%! Something definately not right.
