Powerless? Juice up your phone with elbow grease.

Charger plugged into phone, being cranked

Giving your phone, tablet, or iPod a boost whenever power's not an option (camping, natural disasters, long weekends hanging with your Amish buddy Josiah...), the SOS Charger's a Walkman-sized hand-cranked turbine generator that, when turned for 3-5mins, can provide an additional 5-12mins of talk time for an iPhone -- a significantly quicker charge-up time than you'd receive using any similar, solar-powered rig.
