Many reports and tests in fact do say the new Honda EU2200 will power an AC (15,000BTU).  In my case, it definitely does.  Note, this is the new EU2200, not the older EU2000.  The older unit would not power an AC.  On the 5th wheel we run two of them ganged together when AC is needed — which is seldom.

I would want something like this if I were to get a larger generator than the one I have:
or this one:

Yeah.  I bought a Powerboss for home use with a worthless 30A RV plug on it about 2 years ago to power the house in a winter storm.  Then, I bought my Pod last fall and it has a use.  Mine has a 3500/5250 rating.  The peak rating seems impossible with a 6 HP engine.

Yes, I fully understood this was the 2200. Many report success and many report failure. As I said, there are are several variables involved. Its not as simple as saying it works or it doesn't, or even that it works for one person under all conditions. I've had my 2K start my a/c as well, under some very benign conditions.

6 hp = 4.5 kw mechanical engine output. With generator conversion efficiencies in the range of 90% tops that would be about 4kw electric. So, yes, impossible on a continuous basis. But generators being rotating machines store energy in the moving mechanical parts which allows for a peak output higher than the engine hp rating, for a short time. 

When you think about it, what's going on when you start the a/c compressor from a genny is that you're using electricity to transfer stored energy from one machine with rotating mass to another one. Once the compressor is started the power required to maintain it in motion is much less. 

The problem with a budget inverter generator like the Briggs is that that the high initial electric current needed for a/c startup has to make it through the transistors in the inverter section. Those are likely tightly spec'd to save cost so become the limiting factor in the surge rating. The protection circuit is tripping the genny offline rather than allowing those transistors to be fried, which is a good thing. A higher end genny like the Hondas will have larger transistors which can handle more surge current.

Y'all are funny on this site. And I would also agree that lifting over 50 lbs by yourself, especially planting/turning and lifting is not ideal in any situation... especially if you are camping in the boonies... Needless to say a generator that weighs 100+lbs is asking for trouble on a camping trip. But not having to purchase a generator for your RV and a second for your home would be ideal. 

I found this while looking into the EU2200s.

Not sure if you were aware of this but see below. 

Recall Details

Description:

This recall involves Honda EB2200i, EU2200i, EU2200i Companion and EU2200i Camo portable generators. The recalled portable generators were sold with a red or Camo cover. The name “HONDA” and the generator model name are printed on the control panel. The serial number is located on a lower corner of one of the side panels of the generator. The model names and serial number ranges that are being recalled:

 

Model Name

Serial Number Range

EB2200i

EAJT -1000001 thru 1011342

EU2200i

 

EAMT-1000001 thru 2098790

EU2200i Companion

EAMT-1000001 thru 2098790

EU2200i Camo

EAMT-1000001 thru 2098790

 

 
Remedy:

Consumers should immediately stop using the recalled generators and contact a local authorized Honda Power Equipment service dealer to schedule a free repair. Honda is contacting all known purchasers directly. Consumers who took part in the previous recall for these generators should also take part in this recall.

Incidents/Injuries:

Honda has received 13 reports of the generator’s inverter assembly short-circuiting while in use, including 10 reports of fire. No injuries or property damage reported.

Sold At:

Authorized Honda Power Equipment Dealers, The Home Depot and other home improvement stores nationwide, and online from February 2018 through January 2020 for between $1,100 to $1,300.

Please supply a reference.  While there may be situations when the EU2000 will not power the AC, such as a very high BTU unit or very high elevation, a Google search does not immediately bring up reports that the EU2000 fails to run the AC.  But it brings up many reports that it does.  Perhaps I should say, "In general, the EU2200 will run your AC."
