After reading reviews around the net and on amazon I finally decided to order what many sites are saying is the largest external battery pack for mobile devices. the New Trent IMP 1000 http://www.newtrent.com/Best-IPhone-IPad-Battery-Pack-p/imp1000.htm This thing on paper at least sounds like a BEAST. But I ordered it today and once I get it I'll have to give a review. They offer a 30 day money back guarantee and 6 month product replacement warranty. I have an iPod Touch 3rd generation 32 gig MC model device, so when the battery arrives I will update to let everyone know how well it works, any problems or whatnot. I personally thought it was a great deal though getting a 11,000 mAH battery pack for under $100 You can visit that link to see pics of it, it looks pretty small and compact.
