Abstract

Techniques for an interchangeable modular design for mobile device accessories by separating a mobile device accessory into two modules are disclosed herein. The power and data interfaces between a power module and an expansion adapter are predetermined as a standardized design. The power module includes a battery to supply electrical power. The power module has a form-fitting shape adapted to secure a particular mobile device with the power module. The expansion adapter includes interfaces to be connected to the mobile device and the power module. The power module can receive electrical power supplied from the battery of the power module. The expansion adapter and/or power module may include additional hardware functionalities.
