I was going to recharge my Pandora, and I plugged it kinda wrong. I plugged the USB in the Pandora, and almost plugged the psp outlet in my computer when I realized this mistake.
HOWEVER! I thought "Huh, wonder if this works.." and I plugged it in my Pandora and BOM! It recharged
I use my PSP charger to charge my Pandora as well. Though I'm not quite sure if it's safe or not to plug both the power supply and the USB charger at the same time. Maybe it does bad things as too much power can corrupt
