An electricity supply device for transport containers such as refrigerator containers, comprising a structure adapted to be arranged on one said container, the structure comprising:

• twistlock securing elements in a lower part thereof adapted to be secured and inserted into upper corner castings of the one said container;
• and
• a main cabling attaching a front end to a rear end of the device, the main cabling comprising:
• a first connector at one of the ends;
• and
• a second connector at the other of the ends;
• wherein said main cabling allows said electricity supply device to be connected in series with at least one other electricity supply device, and said electricity supply device to be connected to an electrical energy supply source;
• a secondary cabling connected to the main cabling by which electricity is supplied to electrical equipment of the one said container via a connector of said secondary cabling;
• an articulated arm arranged on each of smaller front and rear sides of the structure, wherein the main cabling and the secondary cabling are attached to the arm in such a manner that the arm is movable between two positions, including a first position parallel and horizontal to the structure, and a second position perpendicular and vertical to the structure, in which in one of the positions of the arm, the twistlock securing elements are secured to the one said container, and in the other one of the positions the twistlock securing elements are free.
