Does this exist? I've been through the backup battery threads, and it seems like all of the options require you to either charge via USB, or you have to lug around an extra power adapter.
Any batteries out there that have a retractable set of prongs that you can plug directly into the wall to charge? (and of course, a USB port to charge the iPhone/other devices)
