I'm halfway through my experiments in AC-to-USB charging and so far, despite the little red light coming on, the 505 didn't take any charge (or lose any) after being plugged in for 8 hours last night. I have one more AC-to-USB charger to try (different maker with slightly different numbers but both for PSP 1000, 2000, 3000) tonight and see if that one works. If not, then it's Hats off to Harry, who gets top marks for accuracy, and I have to go for the heavy brick and little round plug...
(I'd sure like to know why the 505 can charge via USB from a computer but not from a charger!!! Harry, any ideas?)
