Dexim (http://www.dexim.net) has released the US$79.95 DCA199 Foldable Solar-Powered P-Flip for the iPhone 3G and 3GS. It’s purportedly capable of extending talk time up to eight hours, video or game time up to 15 hours, or audio playing time up to 60 hours.
The DCA199 is equipped with a 2000 mAh lithium polymer battery and two camouflage-colored solar panels that receive a charge from the sun. It can flip horizontally or vertically for hands-free video viewing, or fold together for storage and carrying.
To obtain a full charge, the DCA199 takes around 15 hours of exposure to natural sunlight. Users can also still charge and sync their device using the included micro USB cable.
