I found so much misinformation on the net about using an AC with small genset,
cost me some frustration and money.

Through experimenting I found that the largest AC I can run with my Honda 2000 is an 8000 btu window AC. That is run dependably under all conditions. Up in the mountains, Death Valley in the summer, Sitting in full sun, temp and humidity in the 90's in FL, never fails to start it.

The window AC sticking out of the rear window of my RV is aesthetically unpleasing and I have been watching the Easy Start for some time and believe there is now enough reported experience on the net that I would buy one.

If I were starting over I would build in a window AC or use a mini split. I find roof air;s to be obnoxiously loud and over priced.

I agree the honda 2000 works great on smaller AC units and I agree it will run out of steam even with any easy start at between 3000 and 4000ft on the 13.5K AC units. Been their, done that. I have one trailer with a Coleman power cub 9000BTU unit, and the 2000 would easily start and run it at high temps, high altitude (7000+ft) no problem and reliable.

However the honda 2200 with the much larger engine has no problems at 4500ft, not even at 3/4 throttle and has at least 300W to spare and my brother runs his 13.5K AC on the 2200 with stock jetting at 7000ft in 90F temps. the 2200 is IMHO a big improvement over the 2000 for high altitude running. Honda seems to have done the homework in engine sizing to support full output at high altitudes.

This weekend we were at 4500ft, honda 2200 and easy start wasn't breaking a sweat on my trailer. Another person with a 2000 couldn't start his AC (as one would expect) on the 2000, I brought over the 2200 expecting it to not start the 13.5K AC unit at that altitude. Turned off eco mode, and amazingly the AC started right up, yes the 2200 grunted on startup, but amazingly it started the AC the turned it to eco mode and it idled down some. My old 2000 was a 50/50 chance of starting my AC w/o easy start at near sea level.

As a side note I've measured the peak starting current on my Coleman Mach 3 with the easy start with a very fast capture peak reading current probe. Peak starting current is consistently 18.5-19.0 Amps, running current is 13.5A The easy start does what it says, significantly reduces starting current, but it won't do anything about running current, which they make a clear point about.
