For multitaskers who want to power up while tanning
Solar iPhone Leather Case
Besides being more "green" than many other cases, this solar-powered charging case lets you recharge your iPhone battery far away from any external power sources -- if you have sunshine and plenty of time to kill. To fully charge the case's built-in lithium-ion 3.7-volt battery requires 12 hours of exposure to light. (It charges with artificial light in addition to sunlight.)
If you are near a USB power source, you can use the included USB cable to charge the case's battery. Once the case is fully charged, its battery reportedly takes less than 3 hours to in turn fully charge an iPhone.
The black leather case comes in flip-top or side-open designs, and solar-powered cases are available in a few other colors and textures.
