Easy Quick Jumper: Cigarette Lighter Car Jumper
This is sooo smart, especially for women who are afraid to get under the hood. I'm not sure if it's strong enough to work with a completely roached battery, but it will definitely get you going again after you leave your lights on while you're in the store (again!). Not that I know anyone who would do that...
NEVER get caught without the portable jumper on hand. This nifty little gadget only needs to plug into your car's cigarette to give your weak battery a jump and then gentlemen, start your engines!
