What we have here is a solar-powered iPhone case/charger, from Brando.com.hk, an Asian technology importer. And if you think about it, it's really not too shabby an idea.
The cost of this clever case is $48 and it is made of black leather, includes a 3.7-volt rechargeable battery, and a built-in photocell. Two versions are available, a flip-top and a side holster.
