If you’re not impressed by Mojo’s recharging case, then try Mophie Juice Pack Helium. It simply adds 80% more juice to iPhone 5 using its 1500mAh battery, which can be recharged using mirco-USB. An LED light indicates the battery level. It is thin and lightweight. Juice Pack Helium will be available in March for $80.
