Abstract: An interface system for a portable structure, at least one power supply, at least one wired functional device, and at least one wireless functional device. A power interface is operatively connected to the at least one power supply. A wired interface is operatively connected to the at least one wired functional device. A wireless interface is wirelessly connected to the at least one wireless functional device. A controller is operatively connected to the power interface, the wired interface, and the wireless interface. The controller controls the power interface to distribute power from the at least one power supply to the at least one wired functional device. The controller controls the wired interface to distribute at least one of commands and data to the wired functional device. The controller controls the wireless interface to distribute at least one of commands and data to the wireless functional device.

Abstract: A portable power supply adapted to be connected to an external power source and to an electronic device comprises a main module comprising a battery, a satellite module comprising an input port, and output port, and an interface panel, and a tether cable, and a controller. The controller a first mode to allow the battery to be charged when the external power supply is connected to the input port, a second mode to allow power to be supplied to the electronic device from the battery when the electronic device is connected to the output port, and a third mode to allow the battery to be charged and power to be supplied to the electronic device when the external power supply is connected to the input port and the electronic device is connected to the output port.
