Just wire the inverter to your car battery and run the engine. Hard on gas compared to a 3500 watt generator, but you already have the car, inverters a few hundred bucks, and the genny would be at least 2500 dollars
An alternator can't output full power when the engine is idling. You may only get a few hundred watts before the battery starts draining. You can get a generator that will produce much more power than a typical car alternator for under $400.
You're speaking like an alternator is a generator, and doesn't come in various outputs. Your average larger vehicle can charge itself from near-dead at idle or run a 3500 watt inverter, although I have had the odd small car or motorcycle incapable of either.
