Who Should Buy a Dual Fuel Generator

  • Contractors – If you’re working on a job site without access to residential power, a dual fuel generator can provide you with enough power to run your tools throughout the day.
  • Home backup preparations – If you’re worried about the power going out in case of a storm or other disaster, a generator can provide the power you need to run essential medical supplies or appliances.1
  • Camping – If you want to make the outdoors a little more enjoyable, having a portable power source for your trailer or RV is a must.

Who Should Not Buy a Dual Fuel Generator

  • Those with access to power – While those in remote locations will certainly appreciate the portable power a dual fuel generator provides, if you have regular access to a steady supply of power, you likely don’t need a generator.
  • People who hate noise – There’s no getting around it, generators are loud. If you can’t stand the sound of loud noises, you likely won’t appreciate the hum of a dual fuel generator.

Research Tips (from an Expert)

Here are some tips and best practices to consider when purchasing a dual fuel generator. Be sure to do adequate research on the product you are considering purchasing to look for key features and ask your friends, family, or small engine shop if they have any recommendations on dual fuel generators.

  1. Check the wattage – The higher the watts, the more you’ll be able to run off your generator, so be sure to calculate loads when comparing models.
  2. Look for outlets – Less expensive generators will only have a couple of standard 120 volt house outlets on them, while more heavy-duty models will have 240 volt and various other options.
  3. Be mindful of sound – Generally speaking, the bigger the generator, the louder it will be, so keep this in mind if noise is a concern for you.2
  4. Consider portability – The beauty of a generator is that you have an easily portable source of power when you need it, so be sure to choose a model with a wheel kit for ease of portability, as generators can easily weigh several hundred pounds.
  5. Opt for an electric start – While pull start offers a basic, reliable method to start your generator, there’s nothing like starting it with the push of a button. Look for models with an electric start if it’s in your budget.

How Much Do They Cost?

Between $500 and $1,000

For most dual fuel generators, you can expect to pay between $500-$1,000 dollars and still get a quality product. The more watts (or power) a generator provides, the higher the price tag. You’ll also pay more for a unit with more outlets as well as heavy-duty outlets for running an RV. However, the best of that bunch will cost you upwards of $1,200+.

Frequently Asked Questions

Is it cheaper to run a generator on propane?

Generally speaking, it costs slightly less to run a generator on gasoline than on propane, but the price difference is really just pennies per liter, so you can use either fuel source without having to worry too much about the budget.

How long will 20 lb propane generator run?

Generators use between 2 and 3 liters of propane per hour, which means that a 20 pound propane tank should last you up to about 5 to 6 hours. The heavier the load, the less run time you will have.3

Does a propane generator give off carbon monoxide?

While the levels are not as high as a gasoline generator, propane generators still give off carbon monoxide and it’s important to use any fuel burning generator safely in order to avoid carbon monoxide poisoning.

Are dual fuel generators any good?

Dual fuel generators tend to be a more cost-effective and eco-friendly source of power compared to regular generators and are ideal for use in a variety of applications at home or while out and about.
