What power inverter would run my air compressor?

I have a 1.5HP, 3 gallon, 150 psi air compressor. Im going camping and i need it to inflate my tires. But i don't know which power converter (DC/AC) would power it. I heard about 1200 watts should do it.
Update: I have a 12vDC compressor but it would take forever just to inflate one tire. I have 35" tires and i drop the PSI's to about 12 psi's when im on soft sand.
