Sure confusing. I miss the Iota guy explaining the difference between constant current versus voltage based units. My PM4b hauls ass with current/amperage in the normal mode as did my Iota. Other so called voltage based fall flat after a few minutes and don't deliver current. I have a fleet of campers so get to check them all but not an EE like some of you so I just go by real world testing with my trusty Trimetric monitors. I do like the idea of this new unit. To a question asked above about amp draw on generator, I would think that would be at max amperage (I think it was a 75 amp unit) and regardless of the voltage it would be the same 9 VAC draw regardless if it were delivering 75 amps, regardless if the voltage was 13.2 or 15.5?
