Will easy start allow me to run AC on 2200 watt generator?

I see Yamaha has a brand new 2200 generator that looks fantastic. How are the Y's compared to the Honda's?

How bad are the cheap Sam's Club units? They are higher rated then I expected to see.

Qualified maybe.

How hard is converter working to recharge your battery? Are water heater and fridge control boards on? How many lights are on?

You can likely start it, but then it's the job of keeping it running that will really work the gen hard.

Yamaha has a fuel gauge. Honda doesn't. IMO, it goes downhill from there.

Honda EU2200i has an OHC 121cc engine vs. the new Yamaha's EF2200iS 79cc OHV engine. IMO, an OHC engine is an inherently better, more efficient design. The Yamaha's much smaller 79cc engine is going to be working much harder (more wear and tear) to produce the same 1800/2200 watts.

Honda weighs 8.7 lbs. less than the Yamaha (dry weight 46.5 vs. 55.2).

The Honda is rated 53-62 db (1/4 to full load); the new Yamaha, 57-65 db (1/4 to full load). For some folks, 3-4 db is a very noticeable difference.

The one spec that neither Honda or Yamaha advertises is inrush capability. The Honda 2xxx inverter generators have always had much better inrush capability than the Yamaha 2xxx generators in the past. Remains to be seen if Yamaha has improved the inrush capability of the EF2200iS.

People are always quick to post their answers without knowing the question. Is the OP able and willing to do the energy management required to use a marginal generator? Where will the generator be used? If noise is not a big concern, a Champion 3500/4000 watt unit for under $300 will run the AC with no problem, for instance. For all other questions, the answer is, "Honda, or multiple Hondas".

I have owned and operated dozens of generators over the years and cannot simplify the answer to just one brand or model like some of our members do. I don't happen to think a 2200 watt generator is big enough for the application. Regardless of brand.

Probably work in mild conditions. Some combination of heat and altitude could have you without air.

Do people really run a generator 24/7 to keep the RV cool? I would need an extended run fuel tank or I would be rolling out to find hookups.

Interesting comment. Please feel free to reread philh's question. The OP specifically asked for a comparison of the Yamaha EF2200iS and Honda EU2200i generators. I answered his question with a few manufacturers specs along with a few anecdotal comments about those specs. I simply compared the two generators. Nothing more, nothing less.

Please tell me how that qualifies as posting an answer without knowing the question.

Will a 2200 gen run a air conditioner. How high is up?? I run an 8k btu AC with a Honda 2000 under all conditions at all altitudes, even in the summer in Death Valley!

I have run a 13.5k roof air with a Honda 2000, it will start and run it in cool weather but is not dependable as altitude and temperature increase and completely fails when the temp is in the 80's.

Never tried a 15k unit but would not bother trying as even if it did work would be under brownout conditions and one would suffer an early death.

Now I think the OP has added a Micro Aire Easy Start to the equation. I will be following this with much interest as I am experimenting with a modified AC unit and thinking of adding the Micro Aire.

A gremlin is not letting me make this a link?

You don't provide enough information to get good answers.
Make and model of a/c, what temps and elevation will you be using it and what "cheap Sam's Club units" are you asking about?

When you say cheap Sam's Club units, don't know if you're talking about open frame contractor-style generators or inverter generators.
