When talking about giving your device a boost in battery percentage when it is running out, you either have power banks or battery cases. While power banks are preferred largely as they can be stored away, the same cannot be said about battery cases, as they attach to your phone and quite simply, add bulk to your device, as well. Mophie is known for creating such battery cases, and they are popular, to say the least. However, the latest invention from Mophie is a bit different.

Mophie has launched the Juice Pack Connect battery that attaches to your phone with an anchor and provides you with enough power to get through a day or a couple based on what use you have.
