Best Dual Fuel Generators Reviews

1. Westinghouse WGen7500DF Dual Fuel Portable Generator

When compared to the two previous generators models, this dual fuel generator comes at about the halfway mark in terms of the power it produces. This unit is durable, it’s long-lasting, and it’s got some pretty nifty features.

Review

This is of course a dual fuel generator, and it can produce about 7,500 watts when using gasoline, and 6,750 watts when using propane. This is more than enough juice to simultaneously power various appliances like air conditioning, refrigerators, and more. What’s quite impressive is that the 6.6 gallon fuel tank can provide up to 16 hours of runtime.

To make sure that you can start the Westinghouse WGen7500DF Dual Fuel Portable Generator without issue, it comes with a remote key fob. You can use the fob to start this unit from over 100 yards away.

The Westinghouse WGen7500DF Dual Fuel Portable Generator is very durable, as it comes with a 420cc 4-stroke OHV air-cooled Westinghouse engine, a very high quality engine, especially considering the price. Moreover, this is also a low-maintenance unit.

In terms of outlets, this particular generator comes with dual GFCI 5-20R 120V household Duplex outlets and a single L14-30R 120/240V 30A twist-lock outlet. Although this generator weighs close to 200 pounds, it comes with wheels and a durable frame so you can push or pull it.

PROS

  • Plenty of power
  • Ideal to power various items at the same time
  • Wheels for portability
  • Very high quality and durable design
  • Long runtime on a single tank
  • Dual fuel capability

CONS

  • Quite heavy
  • Could use a couple more outlets

2. DuroStar DS12000EH Portable Dual Fuel Generator

If you are looking for a big generator with a lot of power, the DuroStar DS12000EH Dual Fuel Generator is a prime choice.

Review

As we said above, this is a true powerhouse, as it comes with 12,000 watts of peak power and 9,500 watts of running power. Thanks to the DuroStar 18 HP 457cc OHV engine, this unit can power pretty much anything.

To help you plug in all of your appliances and tools, this unit features two 120V household outlets, one 120V 30A twist lock outlet, one 120/240V 30A twist lock outlet, and one 120/240V 50A heavy duty outlet, along with DC charging posts as well.

The DuroStar DS12000EH Dual Fuel Generator can use both gas and propane, and with an 8.3 gallon fuel tank capacity, you can use this generator for nearly a whole day straight without having to refill the tank.

Something you might like is that this generator is both CARB and EPA compliant, so although it  does produce emissions, it’s about as good as it’s going to get in terms of eco-friendliness. The fact that this generator comes with a low oil auto shut-off feature is something you might appreciate, not to mention that it’s really easy to start.

PROS

  • Good amount of power
  • Many outlets
  • Large fuel capacity – long runtime
  • Gas/propane
  • EPA/CARB certified
  • Easy start
  • Low oil auto shut-off

CONS

  • Doesn’t do well in cold conditions

3. Ford 11,050W Portable Dual Fuel Generator

Here we have a high-quality dual fuel generator that can put out a whole lot of power, plus it comes with some neat features.

Review

This particular generator, as implied by the name of it, puts out up to 11,500 watts of energy, which should be more than enough to power a variety of appliances simultaneously, such as televisions, refrigerators, AC units, and more.

This generator is a bit large and heavy, but it also comes with large never-flat wheels, as well as a pulling handle to ensure maximum portability.

Something you may also appreciate is the electric push start, so you don’t have to spend forever trying to get it running. Simply push the button and it turns on, just like that.

Of course, one of the best features of the Ford 11,050W Dual Fuel Portable Generator is that it can use both gasoline and liquid propane to generate electricity. It also has a feature which allows you to seamlessly switch between fuel sources.

This unit features a 6.6 gallon fuel tank and can run for up to 10 hours on 50% load gas. In terms of outlets, the Ford 11,050W Dual Fuel Portable Generator features 4 x 120V outlets, a 120v AC 30A twist lock outlet, and a 120/240V AC 50A RV outlet.

PROS

  • Electric start
  • Seamless fuel mode switch
  • Long runtime on a single tank
  • Super durable

CONS

  • Heavy 
  • Extremely loud

4. Champion 3800-Watt Portable Dual Fuel Generator 

This is a smaller, more portable, more affordable, yet less powerful dual fuel generator than the one reviewed above. It’s a good option in terms of portability and convenience.

Review

What is nice about the Champion 3800-Watt Portable Generator is that it is not overly large or heavy, plus it comes with large wheels and handles for easy portability. It’s the kind of generator that you can use at home, at work, or on the campsite as well. This particular unit is designed as “RV ready.”

In terms of fuel usage, this unit can handle both gas and propane, and it comes with a safety fuel selector switch included to allow you to switch between fuel sources without interruption.

In terms of the gas tank, it can hold 3.9 gallons of gas, and on a full tank, you will get roughly 9 hours of runtime out of it. Keep in mind that it will run for about 10.5 hours on a full tank of propane; this unit can hold 0.6 quarts of oil, which is included, and it also comes with a low oil indicator and auto shut-off for low oil.

This is a 4 stroke, single cylinder, air cooled motor that can put out up to 3,800 watts. No, the wattage is not huge, but still enough to power a few of appliances simultaneously. To make life easier, the Champion 3800-Watt Portable Generator also comes with an electric start feature - just push the button and it turns on.

PROS

  • Ideal for basic use
  • Works great for a couple of appliances
  • Electric start
  • Oil is included + low oil shut-off 
  • Propane + Gas 
  • Long runtime on a single tank (considering the size)

CONS

  • Very loud
  • Needs some time to warm up

5. Sportsman GEN4000DF Portable Dual Fuel Generator

If you need a smaller and more affordable generator, just to power a couple of things when the need arises, the Sportsman GEN4000DF Portable Generator is definitely a good option.

Review

This is a good option if you need a generator to power two or three things at the same time. It can be used for things like compressors, AC units, refrigerators, TVs, and similar times. It has 3,500 watts of power.

What is nice about the Sportsman GEN4000DF Portable Generator is that it’s not all that large or heavy, which helps with portability. It’s a good generator to stick in the truck or RV and take with you on the go. That said, unlike the other models we have looked at, it doesn’t have wheels, which is a bit of a drawback, although not a deal breaker.

In terms of fuel capacity, if you are using a standard 20 liter tank of propane, it will run for about 12 hours, and just slightly less on a full tank of gas. What does need to be mentioned is that this unit is loud.

In terms of outlets, the Sportsman GEN4000DF Portable Generator comes with a 120V AC RV outlet, 4 regular 120V AC outlets, and a DC battery charger outlet. It might not be the No. 1 most durable generator on the market, but for the price, there’s nothing to complain about.

PROS

  • Lightweight and portable
  • Good for basic use
  • Lots of outlets
  • Decent fuel capacity/runtime
  • Affordable

CONS

  • No wheels

FINAL VERDICT

The bottom line is that if you need a good generator that can run on both gas and propane, you should strongly consider any of the above products.

Just remember to look for how many watts you need to power your appliances and equipment.
