Set of 2 pieces.
Genderbender Inverting DC Cable (Pack of 2)
This will change the polarity of any DC output. Converts the center negative DC outputs of the Strom Mobile to center positive.
You can also change the polarity of a PSU’s output with these cables: Plug it into a center negative DC output and this cable will change it into center positive (and vice versa).
Both plugs are white color for easier recognition.
