One of the biggest problems with the iPhone is running out of battery life. If you use yours with any zeal, you'll know the horror of leaving your Apple phone charger at home for the day or (traumatizing) going out of town without it. But thankfully, iPhone battery cases do exist.
Incipio makes a high-quality external battery case, with the OffGrid Battery Case. But, for the moment, it's only available for iPhone 4 and iPhone 4S. In fact, look around and you'll find that the iPhone 5 is still new enough that there aren't many cases out there that promise to extend your iPhone 5's battery life.
But there are at least two. Mobile accessories maker Mophie touts itself as the maker of the first iPhone 5 battery case, first with the JuicePack Helium, and now again with the Juice Pack Air.
At 1700mAh, the Juice Pack Air is a two-part case with integrated battery and lightning adapters. Available in either red, black or white, you charge it up via USB. But the nice thing is, when you plug it in to charge, it'll charge you Iphone 5's battery first.
It's got LED's on the back that let you keep track of its charge, should you actually need to draw on the the backup battery, which is pretty handy.
Something else we like about this case is that it really does seem to pull double duty, in that the case is more than just a vehicle for attaching an external battery back. It seems solid enough as a case in its own right, so it should give your iPhone 5 a pretty good level of protection.
The drawback is, Mophie's Juice Pack Air certainly isn't cheap. Hitting the market this week at around $100, not everyone going to think it's a great deal.
But external battery cases for iPhone 4 and 4s were pretty steep when that device was new too. And now, a good model, like Incase's OffGrid, is totally affordable (we've got it for less than $40.) So hopefully, as more and more similar iPhone 5 accessories start rolling out, the price will drop as well.
