Looking for advice to a 12 volt electric car question.

Hi guys looking for advice to a 12 volt electric car question.

The question is if 12 volts DC were to be the only available power source, what are the most logical choices for powering a 120V ceramic heater element ranging from 900W to 1500W.

I can see that there are power inverters that are able to supply the required amount of wattage, and I have looked at a couple of upconverters, but it occurred to me that there may be an easier way considering it is merely a resistor of sorts.

Since this is just a resistor can it be ran from a 12 volt source directly, or would this be folly to pursue this path?

If there is a thread I missed pertaining to this topic that is recalled please direct me to it.

Running a 900 - 1500 W load continuously from a car's 12 V system is not a good idea. It means that you will consume between 75 and 125 amps. Using an inverter to get 120 V will probably make that 100 to just below 200 A, because of lousy efficiency of low voltage inverters. The generator will have a hard time supplying that much current.

Your second idea will not work either, if you connect a 120 V resistive device to 12 V, you will only get 9 W out of the 900 W heater. I think that you should try and find another solution to your heating needs.
