Battery-operated charger working with iPhone


Jul 1, 2007
Has anybody found and used successfuly a battery-operated charger for the iPhone? It would be great to have on a plane flight, when there's no other source of power (that rules out the Sun-out of reach- and the MacBook Pro, with a dead battery after 3 hours of use, as a potential source of power).

There are plenty of those chargers for the iPod. I even bought one that is advertised for use with the iPod Touch: the Griffin Tunejuice2.
Well, don't get it. It is a life-sucking device! Each time I connected it to the iPhone, it (the phone) was completely drained in less than 1 hour.

If you have found something that actually works, please share your experience here.
