Here's from a past post of mine:
Definitely check your AC's power draws. They are not all the same.
I had to replace my 11000 btu ac & since Dometic no longer makes it I went with their Hi efficiency 13500 AC. (I think if more people knew about this HE unit they would buy it.) Here's the power draw details using a Honda 2000.
I fired up my new Honda 2000 & plugged the Kill-a-watt meter into it. 126 volts. Then I plugged in my motorhomes 30 amp power cord with the proper adapter. I did not bother turning the breaker off to the converter based on my earlier analysis. The draw was 2.6 amps. Then I turned the AC fan on low. 4.5 amps. Then I turned the AC on and it went to 11+ amps and slowly climbed to 12.5 amps and had no problem running. In my motorhome the AC was nice & cold & the battery was being charged. All lights worked fine. I switched the eco on & had no problem. I switched the AC fan to low let it run for 1/2 hour. The draw then was 11.5 amps. Sweet. This high efficiency AC is worth every penny!
Air temp = 87 (hotter than before)
interior motorhome temp 95+
Gen only = 126.6 volts.
With my MH plugged in & converter left on = 126.2 volts 2.73 amps, 176 watts.
Turning the AC fan on to LO = 125.6 volts, 4.34 amps, 416 watts.
Adding the AC compressor
= 123.8 volts, 11.1 amps, 1210 watts. These slowly went up to 11.52 amps & 1250 watts.
Turned the fan on HI = 123.2 volts, 12.5 amps, 1381 watts. These numbers slowly drifted a bit higher.
Turned the fan back to LO & let it run 15 minutes. Nice & cool inside. 123.2 volts, 12.49 amps, 1400 watts.
My elevation is only 750 feet.
PS I did try the Supco on my original AC & had a RV dealer install it. It seemed to have little impact & the AC unit died later.
borrowed a Honda eu 3000 i and it powered up the a/c without a glitch. what a sweet genny, but pretty expensive to use in the boondocks for a couple weekends a year. I might consider a Champion for the price.
