Mophie's Juice Pack Air Plus for the iPhone 4 ups the ante with a 2,000 mAh battery
Now you can even get more battery life out of your iPhone 4 with Mophie's Juice Pack Plus combination iPhone 4 case and extended battery. Even though the previous iteration boasted a reasonable 1,500 mAh lithium polymer battery in its casing, there is actually a larger 2,000 mAh one inside of the Juice Pack Plus for the iPhone 4.
Essentially, it still manages to retain a similar footprint at 1mm thick and even sports the same design with the speaker which routes the audio from the bottom of the smartphone towards the front. Furthermore, it is charged the same way through its pass-through microUSB port which not only charges the handset, but also allows you to sync it to iTunes on a computer. Finally, there is a manual switch that will enable you to charge the iPhone 4 – with a four-light LED indicator which lets you know how much juice is stored on the Juice Pack Plus.
So for those power users out there, they can probably find some kind of solace dishing out $100 for the accessory as it'll only increase their usage out of the venerable phone. Additionally, it'll soon be available in a variety of colors like cyan, magenta, and yellow.
