Ayup. They're meant to charge the battery, -not- start the car.
Trying to crank over a vehicle with one would likely blow one or
both
fuses for the lighters.

The one I have, likely from Radio Shack, is 16 AWG and 4' long, so
it's more of a lab bench jumper. They sold a series of power supplies
with lighter sockets for outlets. I don't know what they meant it to
deliver power to, but it works well to charge my tractor battery
through the dash outlet I added for the flasher. Cats prowl the place
I store it so I don't like to leave the hood raised and charger wires
clamped on the battery.

The jumper box on the tow truck I used to run (which ended my
automotive career) had a molded bakelite shell with welding style
connectors inside. They always made a really solid connection.

Something like that.
