Mophie's long-awaited battery case for the iPhone 5 has arrived. The Juice Pack Helium follows a close line made by its iPhone 4/S predecessors that boasts a familiar and favorable design. Mophie is considered to be the name when it comes to picking up an iPhone battery case. Now while Mophie's Juice Pack line of battery cases aren't known to carry the largest internal battery capacities on the market, we think they have a lot to give despite the fact. Juice Packs are generally the most reliable and pleasing to use iPhone battery cases, so naturally we have very high expectations for the new Helium model. Be sure to catch up on our full review down below if your iPhone 5 is in need for an extra serving of Mophie juice!
