Hello to all... My daughter has an MP3 player that charges by the usb cord that hooks up to the computer. I also have a cell phone charger that is also a USB charger but plugs into the wall socket to charge the cell phone. my question is can I use the same carger for my MP3 player and my PSP, with out messing anything up? anything would help
if your cell phone has to be plugged into the wall socket then it's usb cable is not a charger but just a data cable. what is the output voltage of the cell phone charger as usb ports are only 5v dc?
