If you are the lucky owner of the new iPhone 3G (yes even at the Reunion island where I live, there is a 3G now…) you may be dissapointed with quite little battery life. You should know that there are solutions – solar solutions – on your problem.
The solution is a solar powered case which not only protects your iPhone from everyday scratches and hits but also provides a nice solar charger. Apparently if there is a direct sunlight this charger can provide enough power to operate your iPhone in less then 3 hours. To fully recharge the iPhone it’ll take 10 hours.
Every case has built-in battery which can re-charge once your iPhone. This battery has a 1500 mAh capacity and will recharge itself through the solar panel which we can see on the front of the case, or via Mini USB.
The iPhone 3G Solar cases are available in black or white colors.
