6. Firman Dual Fuel Portable Generator

Firman H08051

The Firman comes with a large eight-gallon gas tank, so you can get 12 hours of runtime on one tank of gas. The larger gas tanks are beneficial during an outage, since you don’t have to worry about filling it so often. It is also powerful, with a 439cc engine and 8,000 running watts when using gas. When using propane, you get 7,250 running watts.

Even with the high number of watts, it runs quiet due to the whisper series muffler. It starts easily with the push button, and the 10-inch wheels and U-shaped handle allow for easier transportation from one location to another.

On the negative side, it is heavy, and there isn’t an AMP or Wattmeter to help keep an eye on these levels. We liked that it does come with a three-year warranty and is CARB certified.

  • Large gas tank
  • Powerful
  • Quiet compared to others
  • Maneuverability
  • No AMP/wattmeter

7. WEN Dual Fuel Portable Generator


The WEN is a heavy-duty, powerful generator that would be great as an emergency backup. It has a 457cc engine with 8,000 running watts on gas and 7,500 running watts on propane. The runtime is 8.5 hours at 50% load.

The panel has six outlets and a 12V DC cigarette lighter-style plug. Simply plug your transfer switch into the NEMA 30-AMP twist lock in times of need. It has an automatic voltage regulator and overload protection. It starts easily with a key, and there is a backup recoil start. It has a switch to convert from gas to propane and an hour meter to help with scheduling routine maintenance.

We noticed that it burns through oil fairly fast in the beginning but seems to slow down when used at a later time. It is noisier compared to the Firman but runs strong. It is CARB compliant and comes with a two-year warranty.

It runs for 11 hours at 50% load since it has a large eight-gallon capacity gas tank. There are six sockets on the control panel, along with an hour meter. On the downside, the flat-free tires are a bit small for its 235-pound frame, and the generator doesn’t appear to be as durable compared to others on this reviews list.

It comes with a maintenance-free battery and a low-oil shut-down safety feature. In order to switch it from gas to propane, you have to turn off the generator, switch it over, and then start it up again. It is EPA approved, with a limited two-year residential warranty and a 90-day warranty for commercial use. Note that this is not CARB compliant, so it cannot be sold in the state of California.

Buyer’s Guide

Dual fuel generators are a great option for providing continuous power and greater peace of mind during power outages. There are a few things to consider when buying one of these generators. We’ve included the following buying tips to make it easier to make a decision about which one is right for you.

Benefits of a Dual Fuel Generator:

Versatile: You can choose between gas or propane and adjust for your needs. If you just want to run a few power tools, then the propane will provide adequate power. When needing to power your house, the gas option is the best route.

Cost-effective: Propane is cheaper and cleaner to burn than gasoline.

Increase storage time: Propane can be stored indefinitely, so when the lines are long at the gas station, you can use the propane you already have on hand.

Continuous power: You can easily switch between both fuels, giving you more runtime on your generator.

Features of a Dual Fuel Generator

Power output: The higher the wattage, the more power a generator will have. On dual fuel generators, the propane option will produce less power than gasoline.

Running watts vs starting watts: The running watts is what the generator will use to keep everything operating. The starting watts are how much power the generator needs to get going, but it can’t sustain those watts (which are higher) for a long period of time.

Electric start: Most will offer a turn-key start (one on our list has a remote start), as well as a backup pull-start.

Low-oil shutoff: When the oil level gets below the minimum level, it will shut down to prevent damage to the engine. Some will have a low-oil indicator light to let you know that it needs attention before the engine shuts down.

Runtime: This describes how much time they will run at 50% load with a full fuel tank. The larger the tank, the longer the runtime will be. Propane won’t have as long of runtime as gasoline, usually an hour or two less.

Control Panel: When the outlets are covered, it will protect them from water, dust, and other debris. Four or more outlets allow for the best wattage use because the load is spread out. So, the more outlets you have, the more opportunities to operate more objects. Keep in mind that the more you plug in, the more power is needed, which means the generator will use up fuel at a faster rate.

Wheels: Many portable generators will come with a wheel kit, which allows you to maneuver the unit to different areas. Generators are heavy and much easier to move around with wheels and handle. Duel fuel generators will typically weigh less than a gas-only generator offering the same power.

Fuel gauge: This is useful, especially if you are using the generator in an emergency situation. You can keep an eye on the levels and reduce the risk of running out of fuel.

Tips and Considerations

Safety: Look for models that offer overheat protection, low-oil shutoff, and overload protection. These safety features are in place to protect you and keep your generator running at its best.

Maintenance: In order to get the best performance from your generator and keep it running for a long time, there will be maintenance involved. Change the oil after 100 hours of use, and keep an eye on the filters and change them when dirty. Don’t forget to follow the owner’s manual for recommendations on your specific generator.

Illegal Backfeeding: This is a dangerous practice and can cause serious injury (and death), so take the time to have a transfer switch professionally installed, which will allow you to plug your portable generator directly into your household electrical supply.

EPA & CARB compliant: Carbon emissions are governed by the California Air Resources Board and the Environmental Protection Agency (EPA), with the former having stricter standards that have to be met in order to pass and be labeled as compliant.

Noise: All generators are noisy, though some are louder than others. The more power they have, the louder they are. Running a generator at 50% will help reduce the noise significantly. Some models will offer mufflers for extra noise reduction.

Cost: Generators are not cheap and for good reason: They supply power when needed and can essentially save you in an emergency when power is essential. They come in many price ranges, and it’s up to you to pick the one that will cover most of your needs.


Though there are many choices for duel power generators, we hope that our review list helps you make an informed decision for a generator that will provide for your specific needs.

Our top-rated generator is the Sportsman, offering features that will help run your house with ease during a power outage. If you don’t need as much power/watts, then the Champion is a great all-around generator with an affordable price tag. If price isn’t a deterrent, the DuroMax is our premium option, with its high-powered engine and durability for any task at hand.

When choosing a generator, keep all the features and options in mind and know what your requirements are so you can make a good investment that will perform effectively and remain reliable for many years.
