DC OUTLET

PROBLEM TO BE SOLVED: To provide a DC outlet capable of acquiring adapted voltage value information of DC equipment to be connected, and coping with a difference of an adapted voltage.SOLUTION: A DC outlet 1 comprises: a plug connection part 3, to which a plug 102a of DC equipment 102 operating by receiving DC power is connected detachably; and a voltage information acquisition part for acquiring adapted voltage value information indicating the adapted voltage of the DC equipment 102 from the DC equipment 102 connected to the plug connection part 3. The voltage information acquisition part includes a reader 8 for non-contact reading the adapted voltage value information from an RF tag 102e provided on the plug 102a and storing the adapted voltage value information so that the information can be non-contact read from outside.
