mophie is launching a new juice pack air (model 1145_JPAXP4-VZ) that works with both AT&T and Verizon iPhone 4. The new model offers same features as the original juice pack air, but is re-built to fit both iPhone 4 versions. It combines external battery with a protective form-fitting hard-shell case.
The juice pack air has 1500mAh battery capacity and has a 4-light LED battery status indicator. Using the included USB cable, you can charge and sync the iPhone 4 without removing it from the juice pack air. Other than providing extra power and full protection, the battery case also has a case design that “acts as a virtual speaker box, redirecting sound from the bottom of the iPhone 4 to the front, resulting in a richer, fuller sound quality.”
The dua-compatibility juice pack air is available for $79.95.
