Here’s a quick, cheap solution for building your own portable battery pack. You’re going to
spend about $25 on this solution, but it’s easy to build a number of
battery packs and the batteries are interchangeable and charge quickly.
Unlike when you use the Pelican Power Brick,
you can put the 15-minute rechargeable battery solutions available from Energizer, Rayovac,
and many others, in this battery pack and have it ready to go in under 20 minutes (after it’s
built, of course).
Here’s what you need:

Step 1: Charge the Batteries and
Place Them in the Battery Holder
Charge the batteries with their associated charger and place them in the battery pack. This is
where you will be glad you purchased the quick-charge batteries, because they can be charged
right before you go to school, to work, or on a trip (no more overnight charging).

Do not charge quick-charge batteries at the same time with other non–quick-charge batteries or
other quick-charge batteries of a different brand. Most chargers warn you about this, but I’m
reiterating the fact. Some batteries were not made for quick-charge chargers, and the results can
be anything from all batteries charging slowly, to battery leakage or battery explosions. Be careful
and read the instructions that came with your charger!

Step 2: Solder the Snap Connector to the DC Plug
Unscrew the power plug casing and you will see two connections—one on the outside and one
on the inside. On the PSP, positive (+) is the center pin while the outside is ground (-), so you
need the red wire from the snap connector soldered to the inside contact, and the black wire to
the outside connector. Before you start soldering, make sure you run the wires through the DC
plug’s casing

!!Make
sure the wires and their respective solder don’t touch each other or
you will short your batteries and possibly damage your PSP!!.

Step 3: Play
Well, that’s it! Plug the power cable from your battery holder into your PSP and you’re good to
go. Your new battery pack charges your PSP’s lithium-ion battery
while you play. Your PSP should automatically stop drawing power from the battery pack once
it is charged. However, I suggest unplugging the external battery pack when it’s not in use, or
when the light on your PSP goes from orange (charging) to green (charged). You should also
consider buying a battery pack cover from Radio Shack for additional protection.

I followed this tutorial myself and its pretty useful if you
can't find a Outlet or Car Outlet. Charge on the Go, useful yet simple.
