Battery life on the iPad 2 got you down? This Solar iPad Case from Hammacher Schlemmer should brighten your day. The case promises 10 days of use for the iPad 2, using a solar panel on the case made from photovoltaic ink. That tech can convert both outdoors and indoors light into energy for your iPad 2 to feed on.
Aside from the performance bonus of the solar panel, the case has a stainless steel stand for movie watching and USB and HDMI ports. You can use the former to use your iPad 2 and the case to charge another mobile device.
