The Universal USB Charger Cable can charge the Nintendo DS, Sony PSP, iPod or any device that supports USB charging, all with a single cable. While I don’t know if that makes it truly “universal,” it does handle a pretty wide variety of portable gadgets. You can’t charge multiple devices at the same time, but it’s still more convenient than carrying separate chargers for all of these devices.

The cable costs about $28, and for an additional $21 you can add on USB wall charger that lets you use the cable without any computer at all.
