iPhone Solar Charger is one of the coolest gadgets that i come across! Given iPhone 3GS's hunger for power, solar power is the ideal continuous charging for our precious iPhone 3GS. Currently i have been using iPhone 3GS with my 3G and Wifi on 24/7. As such, my iPhone is using alot of energy. This high consumption of energy has caused my iPhone to use more than 50% battery energy by end of the day. Recharging everynight is a must for me. This iPhone Solar Charger will definitely solve my problem. A good gadget to get!
