Things You'll Need
Instructions
Place the four AAA batteries into the battery holder. Make sure that all the batteries are placed in the proper way, with negative and positive ends where they are supposed to be.
Cut the DC power cord with the wire strippers. You will want to leave at least five inches of cord from the tip of the power plug, not the wall adapter.
Strip the wire casing from two inches of the wire of the cut end of the cord. Tape the negative wire, which is usually black or has a black line on it, to the negative end of the battery holder. Tape the positive end of the wire to the positive end of the battery holder.
Plug the adapter plug into your PSP adapter port.
