Our most used adapters when towing with an Electric Vehicle.

When I was full time, in winter I would rent a 50 amp site. (really 100 amps, 50 on each leg). I used a peak of 7100 watts, and averaged about 4300 watts. Total consumption for the day was iirc about 103 kwh.

I have a break out box that yields one 30 amp and two 20 amp outlets with breakers. My autoformer would go on the 30 amp.

That was far more energy than charging an EV. But less than 50% of what a 50 amp pedestal can provide.
