A case for an eyewear device having a conductive interface includes a housing that receives the eyewear device. A multi-purpose interface, supported by the housing, includes at least one contact arranged to couple with the conductive interface of the eyewear device when the housing receives the eyewear device. Circuitry is coupled to the at least one contact and includes a processor that detects a connection of the conductive interface of the eyewear device to the multi-purpose interface of the case. The processor performs a charging process during a charge state of the case in which an electrical charge is provided at the multi-purpose interface of the case to the eyewear device. Data is exchanged with the eyewear device during a communication state of the case.
