<p>Taking a five day hike, and I want to take a bazillion pictures. It would be nice to have the compass & GPS functionality too, and I want something really small. The obvious choice is my iPhone.</p> <p>As everyone knows, however, an iPhone sucks juice like a baby waking up from a night's sleep. Even if I turn off all the radio transmitters, I just can't imagine my iPhone holding a charge for more than a day.</p> <p>I've poked around looking at hand-crank chargers (not recommended for smart phones), and solar panels seem to have really mixed results. I've also seen chargers that take 9-volt batteries and convert them into juice, but realistically don't know how many batteries I'd need to drain to keep my electronics going.</p> <p>So, what is my best option for having this device last the whole hike, with no recharge?</p>
