I do not regret this investment. After searching and watching some tests, my choice was quickly focused on this version of Mophie Juice Pack. Indeed, the version "Hellium" is thinner than the "Juice Pack Air" and you will recharge up to 80% of the battery. It naturally adds to the iPhone but also protects.
Another advantage, she charged at the same time as the iPhone when you plug all on the sector.
Excellent investment.
Warning: Prefer a purchase "by amazon" rather than a seller "third party" who "break" the prices and most of the time provide you with a counterfeit battery shell.
