Generator

I just found out that the 3250 watt generator from a big box store that came with a RV 30 amp plug in adapter, will not run the A/C on my Trailer. It will only make 13.5 amps or 1625 watts on each of the 110 volt sides. The generator makes 3250 watts at 220 volt. So when you buy a generator at the big box stores and if it makes 220 volt buy twice the size generator. Now I am looking for a new generator. Any ideas?

    I am curious -- what did you actually plug into that "220V" generator? Anything normal for an RV runs on 110VAC and you would have damaged the appliances, etc. had you actually plugged into a 220V generator. I don't think you have given us a clear picture of what you actually bought. Make and model would help for starters.

    The description given appears to be of a typical Chinese made gen set equipped with a 110/220 twist lock outlet and usually a duplex 110 outlet. The somewhat misleading wattage rating is also typical.
  • it would probably help if you posted make and model of generator.
    i'm assuming it's an open-frame contractor generator, right?
