When I first decided I wanted to get a generator for my RV, I was clueless as to which size RV I wanted. I kept asking, “What size generator do I need for my RV?” and I couldn’t even get a ballpark idea of it.

We put together this RV wattage calculator so you could see what you would be able to run depending on how much wattage you have with the generator of your choice. There are a lot of people that don’t need too much power, but if you’re like us and you have a bunch of kids, then you’ll need more power for your RV so that you can run stuff like multiple phone charges or tablet charges, your air conditioner, televisions, microwaves and other appliances that you might want to use.

Using this portable generator wattage calculator can put you on the right track to getting the perfect generator for you. We needed a pretty big RV generator, but you might only need a small camping generator that doesn’t put out that many watts.

Enjoy this calculator so you can get the right wattage of generator.
