Inverter generator without 30 amp outlet

Was given a new Colman 3000w Genny for my birthday. It doesn't have a 30 amp outlet. Can I just use my adaptor and be able to draw enough power out of the standard outlet to run our TT air-conditioning.
  • This is the only 3000 watt Coleman that I find. Does it look like yours? There should be an ID plate on your unit.
    Coleman genset
    Note that this unit has a 30 amp 120/240 four wire twist lock receptacle.
  • I can't find anything like that if someone can post a link it would be awesome

    IF it has a standard DUPLEX receptical, like the ones in your house and if both slots are the same (Measure voltages should be zero top to bottom all 3 same slots, 120 side to side and the neutral (round hole) may or may not be connected.

    There is a adapter.. I don't have the link to it handy but it is a plastic block with a 30 amp RV type outlet and two 15 amp "plugs" properly spaced on the other side.. Fits the duplex outlet and provides a bit less voltage drop.


    Thanks I'll look for that

    Can't say without knowing how much your A/C draws; both the "run" value and "startup". In addition, you need to add in those things that will be running most or all the time .....like the converter/charger and TV.

  • What model? Some have a 30 amp twist lock which you can get an adapter to go to 30 amp RV plug.
    Camco 55272 for example
  • My Honda 3000 doesn't have a 30A plug. You need an adapter for your rv plug. My air conditioner takes 16A to kick in then drops downs to 9A.
  • Yes, and adapter is fine and that's what most of us with inverter gens use.
