I was thinking about getting a Mophie for my IPhone and a friend told me about a new solar back up power source from someone called SolMarketplace (never heard of them). While solar is a fantastic idea because it's green and I don't have to find a wall socket, I'm a little skeptical about just how well it could possibly perform. I went to their website (http://www.solmarketplace.com/products/SoL-Solar-Charging-Case-for-iPhone-iPod.html) and checked out the specs. If what they are saying is true, then my friend could be right and this solar charger/backup source not only performs as well as Mophie, it significantly outperforms it. But I'm still skeptical and I can't find this in stores yet to see if for myself. Has anybody else heard of this?? Has anybody bought one and can tell me what they think?? Should I try this or just get a Mophie?
