The Dexim P-Flip is an interesting solar charger for your iPhone 4, 3G, or 3GS because it is both a dock and a solar charger. The Dexim DCA 223 P-Flip folds into a compact package that’s easy to take with you. Flip it open and the cool looking camouflage-colored solar panels can fully charge your iPhone.
There’s a 2000mAh battery within the dock, so you don’t need to be charging your iPhone exclusively while the sun is out. It takes about 15 hours of natural sunlight to fully charge your phone, or you can simply plug the P-Flip into the wall or a car charger. A USB cord allows you to sync your iPhone to your computer while it’s in the P-Flip dock. You can use it either horizontally or vertically. $79.99 from SkyMall.
