(1) Solar panels: 27 amorphous silicon solar panels

(5) Electrical output: USB plug + AC plug
Just to give you a clearer pic, a HTC Sensation XE has 1730 mAh battery capacity while iPhone 4 has 1420mAh. Thats mean when your Electree is fully charge, if the Sun you can still charge your HTC Sensation XE for at least 7 times and iPhone 4 9 time XD
How much time needed for Electree to fully charge a device (such as phone)?
Maybe you wanna design a panel that can auto-tilt to gain the maximun sun light instead of hoping the user to tilt it manually?
The price of the Electree is still unknown, but ask yourself: would you buy an art piece to charger your phone?
