The invention discloses a direct current (DC) charged transition box which comprises a box body and a circuit board arranged on the box body, wherein the circuit board is provided with a plurality of feed-out circuits arranged in parallel, and a plurality of power supply circuits which are respectively connected by a first air switch; each power supply circuit is provided with a first voltage meter used for monitoring the supply voltage, and each feed-out circuit is provided with a second voltage meter used for monitoring the fed out voltage; incoming line ends of the plurality of power supply circuits are connected onto a master incoming line circuit in parallel; the master incoming line circuit is provided with a main switch; and the starting end of the master incoming line circuit as well as the positive pole and the negative pole at the tail end of each feed-out circuit are respectively provided with a jack. According to the DC charged transition box, the first voltage meter and the second voltage meter are arranged, so that the DC voltage and the polarity can be conveniently checked, and the accidents caused by error of measurement can be avoided; and the DC charged transition box can be rapidly and firmly connected with a transition line by the jacks, and the dangerous operations such as stripping an electric wire are not needed to be specially carried out, so that the personal safety of constructors can be improved.
