Smallest AC that a Honda 2000 will Run?

Like I said, people have posted that they have done it. But you can't run anything else. No converter, lights etc. it would be best to pigtail the AC line to isolate the AC load.

The Big Katuna is right!! I had a hard time believing it but I just looked up the spec sheets on the Mach 8 9200 vs the Mach 3 Power Saver. And the Mach 3 PS is a little cheaper. So if the lower profile isn't critical, the Mach 3 PS looks like the way to go.

Mach 8 9200 btu:
Compressor amps 10.1
fan low - 1.0 / high 1.4
totals 11.1 / 11.5
fan high 200 CFM
weight 89.5 lbs

Mach 3 13,500 btu Power Saver:
Compressor amps 8.3
fan low - 2.3 / high 2.9
totals 10.6 / 11.2
fan high 320 CFM
weight 83.5 lbs

I have the following A/C unit installed on my camper

Coleman Mach 8 Polar Cub (47201A876)
- 9200btu, 11.7 amp on high, 11.2 on low
- low profile

I've ran it quite a few times with the Honda at ~3500 ft. I did have an issue one time where I couldn't get it to run until I shut off the breaker to the converter.

I could not run it with my Champion 2000w generator.

I just bought and installed a coleman polar cub 9200 and it works with the honda 2000. Our elevation is 2,960 feet. Used it this summer while plugged in and kept the camper nice and cool with outside temps well into the 90's. Well worth the money. Only difficulty was figuring how to get it on the roof, two healthy young men, no problem.

Mine runs my coleman just fine as well. My camper has neither oven nor microwave so no concerns there.

My Polar cub 9.2 is eight years old and I have run it on my EU2000 at 7,000 feet with no problem.

We just installed one on our 1990 hard side Shadow Cruiser in June. The Honda 2000 runs it fine here in Oklahoma. The humidity doesn't seem do make any difference except in the run off water from condensation. We knew going in the AC and microwave wouldn't run safely at the same time. No biggie. What did become an issue was that the outlet provided for the microwave was wired in with the service to the AC for some strange reason, and not at the breaker, in the wall somewhere. It's an old 45 amp converter set up. We simply moved the microwave over to the cabinet closer to the bed and plug it into the receptacle there that is on a separate breaker so that when on shore power we can run them both. Our older Polar Cub on the horse trailer ran fine, the same as the new one, on a Honda 2000 genny as well. The new ones are supposed to be even more energy efficient so I don't see a problem. However that seems to be the comfort limit for the generator as the A frame hard side camper we had for a time had a 10,500 btu AC/heat pump combo and the Honda didn't like it very much. Anyone needing a really cheap 9200, new PM me.

Wish I could help out, and would be able to provide feedback, but I took delivery of my new TC in May and ordered the new coleman mach 9200. They instead put the coleman low pro 13.5 unit on. The 13.5 WILL NOT run off a honda 2000. (It will at sea level where I tested it out at the dealer and have beach camped a few times) Unfortunatly I bought my TC out of state. I talked the dealer into mailing me the correct unit only to have it lost in the mail and still waiting on the pending claim with UPS!

An AC unit's compressor motor draws 2-3 times as much on startup. The 2000 Watt Honda or Yamaha will handle a 9.3k but not a 13.5k btu AC unit. With some AC units the replacement of the stock capacitor will assist with the startup demand.

The smaller the AC the more efficient it will be in removing the moisture from the air inside the camper. Higher btu AC units will cycle off to soon.

We have a Polar Cub 9.2 that was installed by the dealer. The reasoning was that it can run off a Honda 2000 and it has a lower profile than the A/C unit offered by the manufacturer. We took delivery of the TC 11 months ago, so I assume it's a newer unit. Our Honda EU2000 Companion runs the A/C, but if we want to use the microwave, we temporarily shut down the A/C. Our experience with the Honda 2000 and PC was relatively near sea-level, somewhere between 500' and 1000', boondocking on the Shenandoah River in July. Nice and humid. We spent a week in The Keys this past August, connected to shore power, and the PC 9.2 performed wonderfully. Staying in Daytona for a couple days, the temp. was 100 degrees with a "humiture" of 120 degrees. We were driveway camping at my sister's and there was zero shade. The PC 9.2 kept us very comfortable.
Full disclosure, I've added some upholstery foam for insulation in the bath skylight and a few windows that didn't have storm windows (escape window in the cab-over, pass-through window below the cab-over and rear door window).
