Abstract

A case for use with a portable electronic device includes a shell, an internal electrical connector, and first and second external electrical connectors. The internal electrical connector is accessible at the interior surface of the shell and adapted for electrically interfacing to a port of the portable electronic device when the portable electronic device is inserted into the shell. The first external electrical connector is accessible at the exterior surface of the shell and adapted for conducting first electrical signals from the inserted portable electronic device through the internal electrical connector and through the first external electrical connector to a first external electrical device. The second external electrical connector is accessible at the exterior surface of the shell and adapted for conducting second electrical signals from a second external electrical device to the inserted portable electronic device through the second external electrical connector and through the internal electrical connector.
