Abstract: In some embodiments, a connectivity device is configured to provide electrical power to a first electrical device and facilitate communications between the first electrical device and at least one second electrical device. The connectivity device further is configured to couple to a cigarette lighter and an external electrical power source. The connectivity device can include: (a) a first removable cigarette lighter adapter having: (1) a first electrical output interface; and (2) a power interface configured to removably couple to the cigarette lighter; (b) a base module having: (1) at least one first interface; (2) a second interface configured to removably couple to the first electrical output interface of the first removable cigarette lighter adapter and configured to also couple to the external electrical power source; (3) a third interface configured to removably couple to the first electrical device; and (4) a first control configured to receive operational instructions for the first electrical device.

Abstract: Some embodiments disclose an electrical accessory configured to transmit one or more first data signals from a first electrical device to a receiving device. The electrical accessory is also configured to transmit second data signals to the first electrical device. The first electrical device can include a first electrical connector and a second electrical connector.
