Yeah, using a kill-a-watt.

The old 24v one is much like an old car battery charger. Gets hot & buzzy.

The new-to-me 48v unit is completely sealed, quiet. So I suspect it's much more efficient - I've asked the EE who sent it to me if he has any info about that.

I'm going to take the car out for a rare "pointless" run tomorrow to mimic another one I did in Dec (similar temps). Data collection!
