Lots of battery power,
Verified Purchase(What is this?)
This review is from: Mophie Juice Pack Helium 1500mAh Extended Battery Charging Case for iPhone 5 - Silver (Wireless Phone Accessory)
I'm very happy with the increased battery life of my iPhone 5 using this charger case. I get double the battery life using this. The only downside is that the case does require an extension cable to plug it in to charge up the phone and case at night and also an adapter for the headphone socket. The case does make the phone slightly heavier to carry and not as slimline. This isn't a big problem as I feel the battery benefits are worth overlooking these few issues.
