Hi All,

I don't know what size air conditioner I have, but I have a Forest River 21' Shamrock 21 RS. (It's the same as the Roos).

In regards to the standard roof air conditioner,

I was wondering if a small Honda Generator would power it?

What cord adapters would I need?

Any answers would be appreciated!

what do you mean small?

a 2kw gen as long as it can continiously put out 2000 watts plus allow for peak draws upon comp start up 25-30 amps for 2-3 secs you might be ok

A colman 12,000 -13,000 btu ac will pull 12-13 amps while running plus have an inrush of 25 or so amps for 2 secs approx


so the answer is possibly - depends allot on the generator

Amps X volts = watts

look at the draw of your a/c - the lable should have the current draw rating

so rent one for a day or 4hrs or the min they allow hrs plug it into your trailer plug you will need 30-15 adaptor for 120V - make sure all lights are off etc and turn on the a/c - just the fan 1st then the cooling if your battery charger isn't drawing allot or not at all it should start

not so easy to wire directly - I believe its wired via either a multi plug and pigtails to your trailer 120V wiring -if your not sure of your electrical skills I recomend an electrican to do it for you perhaps he can make up a connector for you that is nice and safe and isolates the ac wiring from the trailer when pluged into the generator you don't want to back feed into the trailer wiring thats for sure

I would go with the YAMAHA 2400. I know my 2400 will RUN MY 13.5btu AC with NO problems. JMO & 2 cents.

The small Honda is on the edge, as far as its ability to handle a standard AC. I have the Honda 2000, and was not able to get the AC on my 2008 Jayco HTT to start at all. I added a start capacitor to the AC (an easy mod) and it worked most of the time, but not 100%. Monitoring the power, it spiked at about 2200 watts for 2 seconds (with the start capacitor installed), and then dropped to about 1200 watts after the AC was running. With that kind of load, the Honda 2000 is no longer a 'quiet' generator. Maybe quieter than some, but quite loud just the same IMO.

Judging by the many posts on the subject, the Yamaha 2400 is more reliable, in this class of 'quiet' generators, for AC use (13Kbtu AC). Unfortunately, it is not nearly as small and portable as the Honda 2000.


Where do you find these start capacitors?

I have a Honda 2000 and do not consider it adequate to run an air conditioner. At best it is marginal.

As to the start capacitor, all RV air conditioners have them built in but there are add-on "soft start" kits that might help. I don't have a source.

The Hondas and Yamahas are limited with respect of wattage output. For instance, the Honda EU2000i is rated at 2000 watts for only 30 minutes!!! For "continuous" run time, it's rated at 1600 watts.

To the original poster, you need to help us help you better. Find out what size a/c you have and post it here. How many BTU's is it and/or how many amps does it draw? Generally speaking, most here run either a 13.5K BTU or 15K BTU a/c. Google up the make and model if you don't have the instruction manual any longer. That way you can check the specifications for the model you have and then post the info here.

Many folk here could then easily tell you a simple yes or no if the particular generator you want will power your particular a/c.
