Yes, the jacket is usually the biggest consumer. Mine draws 70W when run on full (which I never need to do) at 12v (idle). I have a dual-temp controller and run the jacket on one circuit and gloves/pants/socks on another. I can turn the non-jacket circuit to 100% and the stator stays quiet, but if I turn both to about 55%, the whine starts. The good thing is that whenever that much heat is needed, it is so cold outside that the stator is cooled.
I have LED driving lights as well, they draw only 12W between them.
