Stitchway iPhone / iPod Ultrapower Backup Battery Charger - 3 Pack
Product Review (submitted on August 10, 2012):
Now like others said this will give me ~40% - 60% charge increase, not fill it all the way up. That said I keep these in the car, the GF's purse, and in any travel bag I take. I cannot tell you how useful they are when you are out and about and loosing battery, just pop it on and you'll have enough juice to finish going about your business. They are pretty small, inexpensive enough to not worry about if you lose one, and perfect for the job. Will definitely be getting some more in the future!
