I've been using one of these with the wife and kids on the end of year trip. While in the car we can stream movies and songs to their iPads and iPods while powered through a 2.1A cigarette lighter USB adapter. Great for the drive between Sydney and Melbourne. Also used it with an Apple TV while staying at the mum-in-law's. Wife managed to catch up on literally a season or so worth of TV shows - and not just one series.
