multiply the car alternator's rating (in amps) by its voltage, about 14 volts nominally...light cars and trucks are rated 50-70 amps. ...so thats 700 to ~1000 watts. Divide by 110 (rms) volts, which is the same energy as 110v dc...and you get 6.4 to 9.1 amps at 110 VAC.

This is of course not taking into account for inverter losses.

Indeed, thankfully good inverters, smps, and dc boost and buck converters mostly run in the 90+% range.
