I run two of these when I need a good heavy charge on my 6Kw diesel generator. Or when I need lighter charging I run one on a cheap inverter generator rated at 1600W. The charger draws about 1140 W and the generator runs for 5 hours on 1.1 gallon of gasoline. The chargers do put out 55A. The diesel which will run both uses about 1/3 to 1/2 half a gallon per hour. I've been doing this for 40 years now, have been using the Iota's for a long while, cant remember how long. These inverter generators that run slower while keeping Htz proper are really cool. Run slower = more efficient fuel use. Lately I think I use the small gas generator more than the diesel one even tho winters are long and dark and I run one every day.
