Hic only I had not thought, it is the length of the male part, it was a bit short for my strip and I would have liked to have in the description. I planned to connect 2 chargers Belkin multi 1 and another on a strip cigarette lighter but I could not.
For info it would be good either add in the description, the total length is 70 mm excluding the metal pine tip that it is about 4-5mm. The male placing himself into the cigarette lighter is approximately 32mm. In the car, but no worries in a multi-socket, be careful.
Otherwise EXCELLENT product I am delighted
