Hello. I inherited a PSP without a charger or anything. I just wanted to know what the output is of the adaptor you plug into the wall. On the PSP it says 5V and I've been using a charger around the house that gives it that amount. It charges, but I feel like it's taking a long time to charge than it should. I just wanted to know the amperage output of the official PSP charger to compare the two. Thanks in advance.
