The first digital interface is configured to provide power to a mobile device connected thereto in order to charge the mobile device, and the digital audio signal from the mobile device is passed to a digital to analog converter. A second digital interface or an analog jack may be incorporated, which is connectable to a headphone or other audio output device. ## Claims ### Claim 1 A device for charging a mobile device, comprising: a housing defined by a distal side and a proximal side separated by a perimeter wall; a battery internal to the housing, the battery being receptive to power from an alternating current power source; a single digital interface integrated in to the housing and in electrical communication with the battery; a digital to analog converter with an input connected to the single digital interface and an output, the digital to analog converter being receptive to a digital signal from the single digital interface; an analog audio jack integrated in to the housing and connected to the output of the digital to analog converter, the analog audio jack being receptive to a two channel analog signal from the digital to analog converter to drive a load with an impedance of an audio transducer preamplifier; and a digital port which passes power from a power source to the battery; wherein with the mobile device connected to the single digital interface, the power from the battery is relayed to the mobile device via the single digital interface, and concurrently, the digital signal being received on the single digital interface from the mobile device is relayed to the input of the digital to analog converter, and connecting a first sensor to the digital port and a second sensor to the single digital interface which sense when there is a connector in the digital port or when the single digital interface is connected to a mobile device, or both. ### Claim 2 (depends on 1) The device of claim 1, wherein the analog audio jack is a 3.5 mm stereo adapter jack. ### Claim 3 (depends on 1) The device of claim 1, wherein the analog audio jack sends the two channel signal through connectors to the tip and sleeve of an analog audio connector. ### Claim 4 (depends on 1) The device of claim 1, further comprising a sensor integrated in to the housing and connected to the analog audio jack, the sensor being detecting the presence of a connector in the analog audio jack. ### Claim 5 (depends on 1) The device of claim 1, further comprising: an amplifier circuit, the analog signal output from the digital to analog converter being amplified thereby. ### Claim 6 (depends on 1) The device of claim 1, wherein the single digital interface is connected to a cable with a connector on the opposite end of the cable, the connector configured to connect to the mobile device. ### Claim 7 (depends on 6) The device of claim 6, wherein the single digital interface and the analog audio jack are disposed in the perimeter wall of the housing. ### Claim 8 (depends on 7) The device of claim 7, wherein the single digital interface and the analog audio jack are disposed on the same side of the perimeter wall. ### Claim 9 (depends on 7) The device of claim 7, wherein the single digital interface and the analog audio jack are disposed on opposite sides of the perimeter wall. ### Claim 10 (depends on 1) The device of claim 1, wherein the housing defines a proximal side and a distal side. ### Claim 11 (depends on 10) The device of claim 10, wherein the proximal side comprises at least one adhesive patch. ### Claim 12 (depends on 10) The device of claim 10, wherein the proximal side comprises three adhesive patches. ### Claim 13 (depends on 1) The device of claim 1, wherein the digital port passes power from a power source to the battery and passes a digital audio signal to an external device. ### Claim 14 (depends on 1) The device of claim 1, wherein the single digital interface is an Apple Lighting® plug. ### Claim 15 (depends on 1) The device of claim 1, wherein the single digital interface comprises 8 pins.
