Ordered one of these today. This thing charges your iPod, iPhone, or PSP from the headphone jack in any airplane seat. Perfect. I have a couple of 14 plus hour flights coming up, so that is the last place that I want any of my stuff to take a shit. Nothing worse than seeing that dead battery icon pop up when your less than 100 miles into your first flight. That will make your backpack with $6000 worth of electronics in it useless instantaneously.
