I’ve heard of truckers cooking meatloaf with a lighter plug, but it took hours and was well insulated. I’m calling BS on this one.

And a truck is likely 24v, so twice the power for the same current. It’s also not unheard of for trucks to have high power devices like inverters in the cab, so may have much more current and power available.

12v car battery and alternator is more than enough. The limiting factor is the fuse and/or melting wires. Thats why giant 1000w subwoofers use thick wire and larger fuses directly from the battery.

Vehicles like that will usually have an upgraded alternator, either that or be constantly dealing with a flat battery.
1kw at 12v is 85 amps, that’s well over half the capacity of a typical car alternator.
