Powering an RV air conditioner is a simple proposition.
Besides an RV generator you've got a lot of options.
The problem is most generators big enough to power an air conditioner are too big to be moved by one person.
If this is the case, parallel two smaller inverter generators to get the same effect.
If you already own an inverter generator, you can buy an accompanying compatible unit, which tethers to the original generator with a set of cables, and back to the AC unit.
The Honda companion unit has a 30-amp twist-lock outlet so you can plug into the air conditioner. In this instance, you'll need to buy the companion generator and the cables separately, but then the kit will be complete.
For the Yamaha EF2000iS, there is no companion unit, but there is a "sidewinder" kit which feature parallel cables and a 30-amp outlet. This kit is used to parallel two of the same generators when a companion unit is not available. You can use these sidewinder kits for 3000-watt Honda inverters, as well.
If you don't have a generator yet, or are looking to start fresh, our Honda companion kits are the perfect choice.
Instead of buying all the components separately, just make one purchase that includes everything you need. Inverter generator, companion inverter generator and parallel cables all come in one convenient package. All you need to do is go RVing.
