Solar iPhone Battery Charger
If you have an iPhone and you're a greenvangelist, do you want to show off how green you are with a solar-powered iPhone case?
In sunlight, the case can grab enough juice in two-hours for 30 minutes talk time on 3G and an hour on 2G. That’s enough to make this case useful on its own, especially as outdoors is exactly the place you can’t plug in a charger. The case also has a hole for hooking onto a carabiner and hanging from a backpack — a bad idea in the city, but out in the wilderness and away from pickpockets it is ideal.
