Here's something that I never thought of but am shocked that it's taken this long to appear: a 4-port USB car charger. Since most gadgets and cell phones can be charged via USB, it only makes sense that this would be the perfect accessory for the gadget hound on the go.

It retails for a mere $12, which is a pretty sweet deal for something that'll make sure that you're always full of juice when you're out on the road.
