New Mophie Juice Pack Plus doubles your iPhone 4 battery life

Mophie has long been the leader in iPhone battery power cases – and with their new Juice Pack Plus, they will probably keep that position for some time.

The new Juice Pack Plus provides 2000mAh of extra battery capacity, more than doubling the battery life of your phone. Best of all, it does this in a case that does not make the phone all that much thicker.

Charging and syncing is taken care of with a MicroUSB port, and the phones speakers are “enhanced” through a virtual speaker box.

The case is available right now in black, with the three colors you see above arriving “soon”. The Juice Pack Plus is available directly from Mophie, and retails for $99.95.
