How to Make Your Own PSP Emergency Battery Pack

If you're traveling long distance or anywhere where you can't recharge your PSP's battery, you may find it running out of juice sooner than you think. You can solve this problem by creating an emergency battery pack to power the PSP. You can do this by using a battery pack for four AAA batteries and wiring it so it will plug into the PSP power socket that you would normally plug into the wall. This emergency battery pack can actually run longer than the PSP's regular battery.

Difficulty: Moderate

Instructions

Things You'll Need:

• 4 AAA batteries
• Voltmeter (optional)
• 4 AAA-size battery holder
• 4.0 x 1.7 mm adapter plug
• Adapter plug and wire
• Soldering iron (optional)
• Electrical tape
• Other adhesive tape (optional)

1. Take a battery holder that will hold four AAA-size batteries. Test the holder by inserting four new batteries and connecting the wire leads on the holder to a voltmeter. Make sure you get a voltage reading of 4.5 to 5.12 volts.

2. Get or assemble an adapter cord with a connector plug that fits the PSP's power socket. The PSP takes a size 4.0 x 1.7 adapter plug. You will likely need to get the connector and a wire to connect it to, both of which you can get from an electronics store.

3. Connect the battery holder's wires to the adapter wire. You night need to solder the wires or twist them together and secure them with electrical tape. Some wires from a commercial vendor can be connected by just inserting the battery wire leads into the open insulation on the adapter wire.

4. Insert the batteries back into the holder. Tape them down into the holder to keep them in place if needed.

5. Disconnect the PSP's battery pack to test your new battery pack. Plug your pack into the PSP by connecting the adapter plug to the power socket. Turn on the PSP. The AAA batteries should power the device.

Tips & Warnings

• You can even use rechargeable AAA batteries in the pack, turning your emergency battery pack into a rechargeable one.
