Check the PF of the chargers with the Kill-a-Watt during bulk if possible. AFAIK, .65 PF chargers use more dinosaur farts than the .95+ ones.

I did a Kill-A-Watt with several different converter/chargers and most of them are in the PF 0.70 area. Only the "PF-corrected" ones I have had PFs in the high 90s. Inverter/chargers seem to mostly have their chargers PF corrected though.
Of course it is the VA that the generator or shore power must supply, not the "watts" figure. "Efficiency" is defined using the input watts figure, which is misleading when there is a PF on the load. Using the watts makes efficiency higher---so that is what the salesmen pitch, not the actual input vs output.
Just look at the so-called specs for the various converters out there of whatever brand. They give the input watts, which is way low compared with the VA with a PF 0.7 not mentioned anywhere in their so-called spec sheets! :(
