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.

Let it be known that PNichols EX650 was gifted to him, as in free, and they are no longer in production. It is fine to design your battery charging system and routine around a FREE generator and the amount of amps and watts it produces, but the silent majority of us here PAY for the generator we select, and todays generators are capable of producing far more amps and push larger amped chargers at a faster charging rate, provided you optimize the voltage you charge at by having an adjustable voltage charger, or power supply unit, like a few of us are now using with a volt and ampmeter gauge incorporated into the wiring. This is particularly true if you own one of the newer red, blue or yellow or black generators now on the market that you pay your own hard earned money for.
