According to some embodiments, there is provided a controller that performs communication with a plurality of power supply units each of which outputs electric power to a load. The controller includes a receiving unit, a control information generating unit and a transmitting unit. The receiving unit receives operation information from the power supply units by radio, the operation information being information on electric power output to the load from the power supply units, respectively. The control information generating unit generates control information to control the power supply units based on the operation information. The transmitting unit transmits the control information to the power supply units by radio.

A method of controlling a plurality of outlets and a first and a second non-transitory medium for use in connection with in a power distribution. The power distribution system includes a handheld device, a power distribution device, and the plurality of outlets. The handheld device includes a first controller. The power distribution device includes a second controller and is coupled to the plurality of outlets to provide electrical power thereto. The power distribution device is physically separated from the plurality of outlets and is located not in close proximity to an outlet of the plurality of outlets. Each outlet of the plurality of outlets includes a socket and indicia located proximate to the socket. The first non-transitory medium includes instructions that when executed by the first controller cause the first controller to scan indicia of a first outlet and receive a set of input data. The first non-transitory medium also includes instructions that when executed by the first controller cause the first controller to determine and transmit a target setting of the first outlet based on the first set of input data and the scanned indicia. The second non-transitory medium includes instructions that when executed by the second controller cause the second controller to receive the target setting, and provide electrical power to the first outlet based on the target setting.
