I got a factory 2.6 PSP(dont think that relevant) that i got in the US. I bought it now to Europe and as you might know the volts in US is 110 and in europe is 220, I use an adapter that allows me to place my charger into the european outlets for charging. Heres where my question comes. I have a MadCatz USB that also has a line that i can connect to the PSPs AC port and draws electricity from the computer to charge the PSP, well first can i connect the USB to the computer and transfer files from the computer to the PSP without damaging the PSP or the MEM stick because of the voltage difference and also can i connect the other part of the USB wire to the AC port of the PSP to charge the PSP from the computers electricity. I was just wondering if all of this is safe because the computer is of course running on a 220 volts of electricity. WELL YOU GET MY POINT.
