Battery Life and Low Temps
I have been having a ball up at Iris Meadow off of Rock Creek Road, Close to Mammoth Lakes, CA. It's the steeper side of the Sierras just East of Yosemite. It's a little known area comparably, but v...

Moreover, any generator, (but especially one with eco mode, like the honda eu20001), will always run at no lower than its normal (or minimum in the eu2000i's case) idle. Therefore, it will be producing at least its minimum amount of available power at any given time. If that gennie is producing say 9a (minimum)of 120v power, it would be very wasteful to only use 3.2a of that 9a. But a 45 amp charger at 14.6v and 80% eff. would draw about 7a. Add the 1a for t.v., etc., for a total of 8a out of the 9.
By the way, my EX650:http://www.tappedin.com/hop/html/litegen.htm
even though it spins at 3600 RPM all the time ... isn't "wasting" any/much power when less than it's maximum current is being drawn from it because ... whenever the shaft load on it is less, it uses less gas regardless of it's 3600 RPM spin-rate.
I stand by my assertion that - if you have and are allowed the time and sound tolerance environment - just a small generator running longer will charge RV batteries very close to the same cost as a larger generator charging quicker.
