Yes, the juice you’re already crankin’ out thanks to the undulating energy resource provided by your car’s gas-powered alternator, that is. That nifty little cigarette lighter you no longer use to flame up tasty Newports (because you quit smoking, right?) is now a handy cell phone or iPod charger, sparing your wall outlets from the energy hogging task. Unplug those outlets when not in use, by the way. They don’t stop sucking just because nothing’s plugged into ‘em.

Thanks to Winston Ross for suggesting this tip!
