If you're on the road a lot, chances are you've got a couple of different adapters that plug into the lighter socket of your car. There's a pretty good chance, too, that said adapter is super bulky. I hate that.
The space inside your vehicle is already at a premium, so why not make the most of it? This Micro USB Car Charger by iLuv fits snugly in the space for your cigarette lighter, with no sticking out. The trade-off: it can charge only one of your gadgets at a time — as opposed to larger units that make up for the added bulk by adding ports.
That, and it's cheap at only $10. No more silent road trips after your iPod runs out of batteries, which — after spending pretty much all of a weekend in a car — I can tell you is pretty brutal.
