I'm currently in dorm rooms at a summer camp, and am trying to charge my ipod during the night, as I usually do. However, I'll plug it in, it's around 25%-50% (estimate) charged, but when I wake up in the morning (7-8 hours later), it's been drained to around 5-10%. Even if I plug it in and it's almost full, it drains. Why is this? I also try to plug it in the morning after, and it will charge to 50%, then drain back down to 10%. I don't understand. The charger works in outlets at my house and in the main building, but not in the dorms. Is it a problem with the outlet itself, or my charger? Someone said it might be power surges, but I'm not sure. Help?
