If you are talking about one that plugs into a cigarette lighter plug, why waste money on something that won't even come close to being able to heat the cabin of a car? Most cigarette plugs are on 15 or 20 amp fuses, so 180 to 240 watts. Most of them are lower than that. I learned the hard way a long time ago with a 75 watt model. 75 watts, even 240 for that matter, is just not very much heat.A small heater is much cheaper than replacing a heater core on most cars.
If you are talking about a larger direct wired one, that would probably run more than just getting the heater fixed on the car. Then you have to worry about damaging your alternator/battery to get the amount of heat needed for a car's cabin.
Resistive electric heating uses LOTS of energy.
