I have an old PSP GO that I'm trying to use with an n340 cradle. The cradle takes a PSP 3000 charger, which is different than the PSP GO charger.
I happen to have another Sony adapter that fits - however it supplies 5.2 volts, which is a bit above the GO's recommended limit of 5 volts. Is this enough of a difference to cause damage over time? I don't think the GO has an internal voltage regulator but I have heard that the battery does..
