Car electricity runs on direct current, but almost everything else is alternating current. What you need: an inverter. Some cars have them built in, but you can get one at a store for less than $40. Use the clamps to attach the inverter directly to the terminals on your car battery. Let the car run at idle and you have 110-volt AC power for as long as you have gas. With a 300-watt inverter, you'll have enough amps to run a laptop or even a television.
