One thing I've always wondered though is what's the lowest wattage they can put out, not the peak, I assume they'll simply run less RPMs in the motor, but is there a low point when you can't get any less energy out of them? It'd be a shame to waste a bunch of gasoline to power a few things because you got a 7000watt unit, but only need a few hundred watts at any given time.
