Abstract
Techniques are disclosed for aiding in charging an electronic device using a charging case. The charging case includes a conductive contact and may connect to a conductive contact of the electronic device while still allowing user access to the main connector port of the electronic device. The charging case includes a power module that may receive power from an external power source. The power module may include an inductive coupling coil, photovoltaic cells, or a power cable port. Circuitry within the charging case may control and transmit power from the power module to the electronic device through the conductive contacts. The charging case may include a battery. The charging case may also include a data module for receiving data from an external data source, and the case circuitry may process and transmit data from the data module to the electronic device through the conductive contacts.
