Pining for some added juice on your iPhone 4? Mophie has now officially released their next Juice Pack, which is compatible with Apple’s latest handset. It doubles the battery life and features some sort of 500 mAh quick charge in case you’re in a rush. There are 4 LED battery status indicator lights and some finishing that mimics the iPhone 4′s.
You can grab one from Mophie for $80.
