I completely agree with yours suspicions too.

800amp is a lot of juice, and to put it through cables those size is not sustainable.

The unit has the box with the green led mid cable and i suspect it current limits for safety but I could be wrong.

If the main battery is completely flat you have to override the little box with button on the side.

There is another type of jumper that uses capacitors to start the car intead of a battery, its quite a clever piece of kit that boosts the voltage to charger the capacitor bank enough to give you start power.

I have seen a video of it start a car entirely on its own once charged which is impressive.

Also came across this which was interesting
