A folding, 30 watt panel capable of charging my Macbook Air, or a car battery, or a deep cycle battery costs about the same, though it needs a bit more space to lay out.
Of course, no need to buy 'refills' as long as the sun is up there shining. Even on most cloudy days, you can charge.
Not to say a 'fuel cell' wouldn't be useful in an arctic winter, or deep under ground... but good luck getting a signal. Still, you could enjoy your mp3 tunes until the end....
BTW, if it can charge a cell phone, it can run a small LED light, or charge one.

Does it have a standard mAh rating cos saying it can charge a smartphone for 2 weeks isn't very accurate. What if you want to plug in a portablt USB HDD and a smartphone, how long would it last?
