Most iPhone users will agree the biggest problem with an iPhone is the battery life. Each new version of the phone has improved, but it is still easy to drain the battery before noon. So what is a person to do? Carry around the cord to recharge it on your computer? Or from the nearest outlet? If you are working from a desk, that is no problem. But for the rest of us that use our phone while traveling, we need an alternative. And one of those alternatives is Mophie's Juice Pack Air series. One of the most popular items in this line is the Mophie Juice Pack Boost. This lightweight design is easy to carry with you, which means you’re always prepared for that dreaded "low battery" warning. Inside the Boost is an ultra-compact 2000mAh rechargeable lithium-ion polymer battery that more than doubles the battery life of your iPhone or iPod. There are lots of smaller, less expensive chargers on the market, but most don't have the power to charge your iPhone back to 100%. The Juice Pack Boost does. And it does it fast. One of the unique aspects of the Boost is its design. The battery can act as a base so your screen is displayed and your phone is easy to use. The Mophie Juice Pack Boost is compatible with all generations of iPhone and iPods. (It will charge an iPad, but not to 100%. For that, you'll need Mophie Juice Pack Powerstation.) And for only $49.95, it can be your lifesaver! And if you are looking for a case for your phone and Mophie Boost, check out our Double Decker case!
