I agree with many points on the above. It can only run 30 amp with two genny's hooked together but I purchased the Companion 2200i because of the heavier plug for 30 amp. Yes, I did add an adapter to connect the TT 30 amp cord and also purchased a longer adapter to make it easier to connect when the genny is in the genny box. I do have the Micro Air on my 15k AC that works perfectly. This seems to be a perfect set up for our HOT Florida summers.
