I bought 2 of these so I could connect them together for our camper and what a surprise 1 will run the air conditioner just fine. It's a 13500 BTU roof unit .
I just bought this last week, I haven't used it yet but I'm sure it will be fine, Westinghouse has been around for a long time and they stand behind their products. Also like the lifetime technical support they offer.
Has all the features and power I need...very easy to start; runs quiet; has the features needed to save gas and generate good amount of power....wish it was designed with more weather resistance so you could use it during wet conditions but this design deficiency seems to plaque most portable generators
