My AC adapter for my psp died. I was charging the PSP with my laptop but I forgot like a week and died. My cousin has the adapter but for the PS vita, will it work?
Unfortuantely this wont work.
The PSP uses a AC adapter with a specialized tip for AC charging:
The PS vita uses a unique output port to the PSvita from a USB input:
Basically you would need a USB input that leads to a AC Tip output, which wont happen because a) they don't make these cables, b) USB output's at most 500mA which wouldn't be enough to charge the battery in most cases.
