Right, a 12 VDC to 120 VAC inverter will work with any car.
The Sparks DC to DC converter is rated at 100 or 120 Amps at 13.5VDC, can't remember which...
So conservatively good for ~1200 Watts 120VAC. This will power a vital appliances in the house.
It would be best to not push the max on any of these electronic converters in the train between your HV car battery and your home appliances.
Be aware of Sine Wave inverters for sensitive electronics versus the cheap Square Wave inverters.
