If all we want to do is charge one/two batteries (Gr29,), is the 1000i enough. Prefer not to go 2000i, even for only $200 more. I'm concerned about size and weight, somewhat ... and will never ca...
I have an old Yamaha 1000 generator (long before the invertor type) and it works great for charging the batteries and it will run a 5,000 btu AC.

If I had to do it over again, I would pay the difference for the 2000 watt generator even if I don't immediately need the power. It doesn't run hard at all and it isn't any heavier than my old Yamaha 1000.
