Good to know they can start the car on their own, I might just buy one. I guess because the cables are short there is not much voltage drop( my jumper cables are 5 or 6 feet long and even if they are thicker there is too much drop to start car with totally flat battery, I think they were 'rated' up to 2000cc engines) and because they starting time is short they do not heat enough to burn or melt insulation. You can look at them kind of like fuse, fuses are also thin and short but still can handle a lot of current.
As far as the box in the middle of cable I guess that is no voltage until connected to battery and reverse voltage protection box to prevent accidental short circuit and wrong connection. So there is no power to crocodile clips until they are connected with correct polarity, override button is for totally flat or missing battery.
I also like the idea of powering laptop on some of them.
