The Handi is also quite a bit louder, than the standard 3000i.

True the Handi (57dB) is louder than the 3000is (49dB). However, the Yamaha in question is in between the two at 53dB. For reference, the dB range is logarithmic with the noise energy level doubling about every 3 dB. However, human hearing perception hears a 10 dB difference as about twice as loud even though the sound energy is really 10 times more. Comparison of day to day sounds, an air conditioner, or conversational speech is about 60 dB. Light traffic, or a refrigerator is about 50 dB. If you are expecting to run the generator with nearby neighbors, quieter is certainly better. However, you should check in advance whether generators are allowed at all. For instance, here in Wisconsin, operation of generators is not allowed in State Parks, period.

There are lots of stories of how certain size generators will run the ac. I listened to one such story and bought the Champion 3100. No such luck, as it wouldn't run the Dometic 13.5 unit. Bought 2-Honda 2000's and worked like a charm.

I have the Yamaha 2400 and it will start and run my 13.5 A/C. I have compared the sound level to a Honda 2000 and it is very similar. Both are plenty quiet so as not to annoy others in the campground.

I have the 2400 Yamaha. IMO, it is a less obtrusive sound than a Honda 2000. Maybe a tad louder, but a lower frequency.

It ran the A/C in my last trailer, but the one time I tried on the new trailer, it didn't.

Here's a video of it doing the job. Note, it is louder while running a max load. Also, the title says 15.5btu, but it was not.

I am an electrician of 40 years. Get the 3000 and deal with the wait. Your AC will have a much longer life span.. Anything less will require a hard start

kit. Both gen and AC will be maxed out.

And yet I saw a chart made by Honda and they said their 2000 watt would not run a 135000btu AC unit. This chart was made two years ago, and is why I bought my EU3000is. It is what Honda recommended at the time.

According to Honda the EU3000is is 58 db at full load, the Handi is 65 db at full load, the Yamaha 2400 watt is 60 db at full load.

I am not a sound technition so honestly don't know how much difference that is, we are talking about 58 db for the EU3000is to 65 for the Yamaha 2400 watt generators. That is a difference of 7 db between the quietest and the loudest of the three.

Most camp grounds are 50 feet or more apart. How much difference would 7 db make?

According to this chart, very little difference! Less than a pin dropping.:

http://www.noisehelp.com/noise-level-chart.html



If this chart is true I don't see where the noise level is going to be an issue. If this is true my main concern is going to be run time and if they run my AC. I know Honda 3000 watt will, Yamaha says the 2400 watt will.. Both will fit in bed of truck and they weigh about the same.

For every increase of +10db you get twice as loud.

Thank you. For the difference we are talking I don't think it would bother anyone in a cg siteas far apart as the sites are. Keep in mind the generators will be sitting in the bed of my truck which should help quiet the noise also.
