Being an iPhone junky, I am all too familiar with this situation, as the battery of the iPhone leaves much to be desired when longevity is concerned. This has left me to own a small army of chargers and sync cables to try and keep my iPhone up and running during the extensive use that it sees. Anything short of a backup battery source to plug into it means that I need to be relatively close to a car, laptop, or wall outlet to plug in my phone. This leads me to an exciting product that I just received from Mophie. The Mophie Juice Pack Air is a hard iPhone case featuring an internal battery pack. The Mophie Juice Pack Air features on the fly charging for the iPhone with a flip of the switch. The battery backup helps to recharge your iPhone's battery remotely, extending the life up to twice what you are used to from the iPhone. The stylish case is gloss black and gives the iPhone a nice, stylish look while adding to its battery life.
