generator for a camper AC
Question, what kind of amperage do the small camper AC units draw? I believe mine is the 11000BTU Dometic unit and see different numbers when searching online. Do you think a 2100 starting watt generator will be enough? Once running I think the power draw is much less.

My Yamaha 2000 starts my Coleman, however, I know from field experience that the amp draw can vary between units. It also started the Dometic in our Hallmark, The simplest thing to do is try it or install the soft start https://www.microair.net/collections...-soft-starters.

Tony,
Our camper is fitted with an optional 10K BTU air conditioner. The optional propane generator is rated for 2500 W at 77F and at sea-level (IIRC), which is consistent with Dometic recommendations.

Tony,
Is your AC an 11K Penguin II?
https://www.dometic.com/en-us/us/pro...uin-ii-_-20692
Dometic says running power is 1382 W.
Lots of people run their 10K - 11K AC units on Honda 2000 generators.
My gut feel is that your generator is probably OK if well maintained, at sea level, on a cool day, and no other 120 loads.

I have the 2200 watt Honda. Easily starts my 10k AC. I tested the generator when I bought. It will do 2300 watts for an extended period of time, not just a brief surge.

Another vote for the MicroAir EasyStart. Yes, it costs almost $300 and it needs to be installed; which is relatively easy. Do NOT fall for the $20 dollar soft start capacitors...they ARE easier on the air conditioner but they INCREASE the electrical service or amp requirements. Anyone telling you otherwise is selling snake oil. I can give you more, first hand data, if you are interested.

Another vote for the MicroAir Easy Start. I run a Coleman Mach 10 13.5k AC on a Honda EU2200 Companion Genconnex Propane generator. Works great in hot weather and at altitude. Even ran the AC and the 4 stage convertor at the same time at 95f when the battery had dropped to 80% charged, but it sounded like it was running flat out.
