Mophie are probably best known for their Juice Pack Air battery cases for the iPhone and for good reason too as there aren't any other battery cases out there that comes close in terms of design and performance. Mophie also make a universal range of batteries for the people who like their existing case (or no case at all) or just want a portable emergency charger.
Today we are looking at the Juice Pack Boost (specifically the Product RED version). The Boost is about the size of a small chocolate bar and made from soft-touch plastic. The built-in dock connector swivels so it can double as a stand. Battery capacity for the Boost is 2000mAh (it should just be enough for a charge of the iPhone 4S) and the Boost is charged using an included micro-USB cable. Battery capacity is shown using an LED indicator which is activated by pressing the only button on the unit.
The Mophie Juice Pack Boost is $59.95, the pictured (PRODUCT) RED edition donates part of the net profits go towards The Global Fund to Fight AIDS and is available from the Apple Online and Retail stores.
