Kudocase solar case for iPad

Kudo is trying a different approach to solar energy. The new Kudocase for iPad besides solar energy it uses the light inside a room to produce energy.
Kudo claims that if you use your iPad daily in a room with medium light then the tablet will last about 10 days. This sounds interesting since an iPad needs to be charged after 2 or 3 days of use.
Kudocase costs 199,95 $ but it is so much more than a solar case. It has a battery to save the remaining energy, an HDMI port and a USB port for you to charge your smartphone or another device.
Kudocase is expected this June and will be available in black, grey, pink, blue and green color.
