Thanks for the info. Is one terminal cable 35cm long or both together (black and red). I ask because in my plug-in car I can't connect the cables directly to the battery. But at predetermined points of the manufacturer.thank you.

35cm - is perfectly sufficient, for this the box is so compact that the booster has room in the door compartment :-)

They are short. In any case, shorter than starter cables. Just long enough so that with a normal starter battery you can place the device on top of the battery and connect it.
