The iPhone 3G is a wonderful device to behold. That is, if you have some kind of charging adapter to keep its thirst for power quenched. Bluetooth, Wi-Fi, GPS, high-speed data, and don't forget that it makes phone calls too. Let's face it, the iPhone can't get too far from a real power source... until now.
Solar Arcadia, a company devoted to solar power alternatives, has developed a curious and seemingly very useful solar charging accessory for the iPhone.
Cleverly disguised as a leather case for your iPhone, there is a large solar cell embedded in the front flap of the case, and a thin lithium ion polymer battery that snaps into the bottom of your iPhone. The battery pumps out an impressive 1500mah at 3.7 to 5 volts and can juice your iPhone when its battery gets low, however the directions are never clear on exactly how long the built-in battery can keep the phone going. Of course, the solar cell is really intended to charge the case battery, not power your iPhone directly even though it can.
Keeping the charger in the sun or any artifical light source can recharge its internal battery in about 3 hours. If light is not conveniently available, the internal battery can be charged with the iPhone's included charger.
At only $45.95, it certainly won't break the bank and it's available in several colors. They also offer a vertical flip style that has a belt clip built in. Check it out here.
