I'd sure like to see some curves showing wattage output versus RPM for a Honda EU1000i generator.
Honda EU1000i (and Honda EU2000i) low noise and low fuel consumption rates of course only apply at the low ends of their RPM ranges. I'm finding it very hard to digest that the little Honda can put out enough watts into a moderately sized multi-stage charger for just a few hours so as to bring a 200 amp hour or larger RV battery bank from 50% up to a 90% state of charge ... while at the same time just putt-putting along sipping little fuel and making little noise at speeds close to Eco-idle.
Our little (obsolete model) single speed Honda will run 5-6 hours on 1/2 gallon of fuel at it's low-ball sound level (54dB), but the charger it's powering during this time period only ranges from ~15 amps down to ~5 amps into our 200 amp hour AGM batteries.
It seems like the EU1000i either has to be rev'ing up to power a good charger (and sucking fuel and being louder), or staying near idle (and sipping fuel and being quiet) powering a lesser charger and therefore not really be charging larger battery banks up that well ... one or the other. :h
