It's not charging!
Well, from the computer it is. But from my AC charger, it's not. I have a wall adapter for USB devices. I have 2 MP3s. I used my MPIO and charged it via the wall outlet, and that worked well. Charged fully within a couple of hours. MY brother used his iPod and charged it. Worked fine. My P2, uh, didn't work well. I charged it while it had one bar left. It said it was charging. I didn't turn it on to play music or anything. Came back around 5 hours later (on my computer, 5 hours is enough to fully charge my P2), but the bar was still at 1. Anything I'm doing wrong?
