OK, I’m going to go out on a limb here and ask if you remember the song “Jump Start My Heart” by Natalie Cole, hit of hers from 1987, well she speaks about a guy that jump starts her heart when she feels down. That’s what this juice pack does, except it does it for your phone. We are always moaning about how long our phone batteries last, no matter how long they last. Whether it’s a day (HTC, I’m looking at you) to a week (Nokia = win), it’s just never long enough! So the Mophie has a portable juice pack reserve that gives your phone a boost when it’s about to die and you are nowhere near a power outlet or your charger. Unfortunately the Mophie recharges only Apple products like the iPod or iPhone.
