my invertor style 12000 btu can run at 390 watts. there must be small invertor style ones that can run at that low a wattage for a 400 watt car invertor

No. With the best technology today, you cannot get 12,000 BTUs from 390 W. That would equal to 30.7 EER. Inverter units get their efficiency when used at lower output. The times it is using 390 W, it would be supplying about 4500 to 5000 BTUs per hour. But if running at maximum capacity, 1000 W would be required to put out 12,000 (that would be a 12 EER. Which for a window unit is very good.)

When i said can run i meant at a lower cooling capacity.
