A power connector facilitates mounting and repositioning an electronic device via a magnetic field. The power connector can include a receptacle surface comprising a curved surface operable to mate with a curved contact surface of an electronic device, and a device-coupling mechanism operable to hold the curved contact surface of the electronic device pressed against the curved surface of the power connector device, while an angle of the electronic device changes with respect to the power connector. The power connector can also include a power-transfer mechanism operable to transfer at least power to the electronic device, without an electrical wire between power connector and the electronic device, while the angle of the electronic device changes with respect to the power connector.

An electrical receptacle including a body having a plurality of electrical connections, a device face connected to the body, and wherein the device face is movable with respect to the body from an electrically inactive position to an electrically active position. The electrical receptacle may further include at least one pair of electrical contacts which are in electrical continuity when the electrical receptacle is in an electrically active position.

A connection assembly for rotateably and electrically coupling an accessory to a main device includes a housing portion, a rotatable port assembly, and a wire assembly. An end of the port assembly is coupled to the accessory. The port assembly includes an electrical connector member having a first connector end electrically coupled to the accessory. The wire assembly has an electrical wire member having a first end electrically coupled to a second connector end of the electrical connector member and a second end electrically coupled to a power supply. The wire member is spooled around the port assembly and encased in a chamber defined between the housing portion and the port assembly. Rotation of the port assembly in opposite directions causes the electrical wire member to spool more and less tightly around the port assembly without causing pinching or tangling of wires.
