It comes with an AC adapter and a car adapter, so you can use it on the move though the driver shouldn\'t use it because you kind of need to be alert on the road. This mini shiatsu massager is awesome for working out those aches and pains, speeding up post-workout recovery, or just relaxing after a long day! | Shiatsu Mini Massager by Sharper Image
