The mophie spacestation combines the functionality of a mophie space pack and a mophie powerstation. The two major features are power and storage with the added benefits of the powerstation form factor (portability and universal compatibility). The product will ship with a 6000 mAH battery @ 2.4A output in variants of 32, 64, and 128GB of additional storage. As a premium product the design will be similar, yet, more premium than the powerstation w/cables 2014 line. The product will ship with BLE as well accompanying free iOS and Android apps. The current iOS Space app will be redesigned to work with the spacestation and a new Space android app will be ready at launch. Use cases The mophie spacestation has the following use cases:
Supplies up to an additional 60% battery capacity for the iPad Air, 85% battery capacity for the iPad mini retina and 300% battery capacity for iPhone 5/5s Supplies additional memory capacities of 32, 64 and 128GB for tablets and smartphones Pass-through charging with priority for the connected device File transfer from the spacestation to the connected device and vice versa File management via included Application allows for content management between devices (space pack, tablet/smartphone, PC/Macs, iOS/third party apps, cloud solutions via API) Compatible with iOS and Android tablets and smartphones Features:

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help. NOTE 2: Any changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
