Instructions
Place the 3 AA batteries into the battery holder. The batteries must be positioned properly, so the charge flows from negative to positive.
Cut the AC adapter wire 4 to 8 inches away from the plug that fits into the PSP, not the wall plug. Leave yourself enough room on the wire to work with, because you can always cut more wire off if it is too much.
Strip 2 to 4 inches of the wire with the wire strippers. Inside of the cord there will be two wires, a negative, which usually has a white stripe on the plastic coating, and the positive, which is usually red or has no stripe. For each wire, twist the individual copper strands together so it resembles a solid wire with no little wires sticking out of it.
Tape the positive wire to the positive output terminal on your battery holder. Tape the negative wire to the negative output terminal on the battery pack. Secure both connections with extra tape.
Tape the batteries into the pack if they are loose.
Plug the cord into the PSP socket. If the light on the PSP turns orange and the battery indicator on the PSP screen blinks, then the PSP is receiving a charge.
