Eton has made a name for itself with a line of emergency devices—like flashlights and radios—that don't require an outlet to stay powered. And its new BoostTurbine backup batteries promise to keep your other devices perpetually powered too, as long as you've got the energy to crank its built-in folding handle.

The BoostTurbine is available in two models differentiated by the capacity of their internal batteries: the BoostTurbine1000 with a 1000mAh battery for $49, and the BoostTurbine2000 for $59 which can store twice as much power. They're each wrapped in a light but strong aluminum housing to keep them safe during travels, and both offer standard USB and microUSB ports for connecting your mobile devices. Just a minute of cranking generates enough power for a quick phone call or a handful of texts, so just keep in mind that if you need to bring a device back to a full charge you're looking at a pretty gruelling workout.

My issue would be that once your iPhone actually dies, it needs 5+ minutes plugged into a full-power wall socket to even turn itself back on again. I have one of those battery dongles for the iPhone, and when that thing isn't fully charged itself, it wont supply enough juice to start up the phone. So you'd presumably be cranking for a really long time, just to build up enough charge to supply the phone with enough charge to boot up.
