Best Dual Fuel Generator 2020: Power When You Need It

By admin | Home & Garden Tools


Having a power generator is a great way to stay prepared for power outage emergencies. It’s also a convenient and practical solution to your power needs on camping trips.

Why Should I Get A Dual Fuel Generator?

A dual fuel generator has the added advantage for you to use either gasoline or propane. While this makes the dual fuel generator pricier than the typical gas-powered generator, the flexibility of choice is a great plus. In the event of a city-wide power outage, you may not have the option of getting gasoline to run your gas-powered generator if you have no gasoline at home and your local gas stations are down too.

With two fuel options, you can switch to propane if you run out of gasoline to power your dual fuel generator. This is especially helpful if the power outage lasts for days. If you live in an area that experiences seasonal changes, a dual fuel generator might be a better investment than a normal gas-powered generator.

Compared to propane, gasoline has a shorter shelf life as heat causes it to evaporate. On the other hand, while propane has a longer shelf life, it contracts once temperatures drop below 4.5°C (or about 40°F). This in turn causes a decrease in pressure in the propane tank and the generator may not be able to start up if it’s just powered by propane. With the dual fuel generator, you have the option of powering the generator with propane during the summer months and switching to gasoline during the winter months.

Contrary to popular belief, a dual fuel generator is not less effective than a single fuel generator. Whether it’s for powering construction tools, small appliances or the refrigerator and other household appliances during a power outage, the dual fuel generator will get the job done like any other single fuel generator. When it comes to the sizes, output and other specifications, there are many options that you can choose from to find a dual fuel generator that meets your requirements. In fact, dual fuel generators and even tri-fuel generators are becoming increasingly popular due to their versatility as compared to single fuel generators.

What Should I Consider When Buying A Dual Fuel Generator?

The main question you should ask when buying any generator is your total wattage requirement. To determine that, you should list out all the appliances, electrical devices and tools that you expect to run on your generator in the event of a power outage or if you’re out on a camping trip.

With that in mind, let’s take a look at my top five choices that you may want to consider if you’re on the hunt for a dual fuel generator.

If the battery to start up the generator isn’t charged, fret not as this dual fuel generator has a recoil start. The accompanying wheel kit has a pretty durable frame that comes with 8-inch wheels and conveniently foldable handles. This dual fuel generator is 50 State Compliant, and both EPA and CARB-approved.

The TT-30 RV receptacle makes this dual fuel generator an ideal unit for running an RV on your weekend road trips. This dual fuel generator is also sufficient to power your refrigerator or your air-conditioning unit in the event of a blackout. Above all, what makes this dual fuel generator stand out is its optimal portability. There may be times when you need to lift the dual fuel generator and cannot rely on the wheel kit, for instance when you are loading or unloading it, and that is where its relative light weight will come in handy.

Best Dual Fuel Generator (IF YOU CAN SPLURGE – The “BEAST” Option): DuroMax XP12000EH

The DuroMax XP12000EH is another great product by this California-based company. It’s equipped with a robust and powerful engine— 18HP 457cc OHV engine. The engine is mounted using four-point rubber mountings, which makes sure that this dual fuel generator runs smoothly and is made to last, even if it’s subject to tough working conditions. The cylinder sleeves and bearings are made from quality materials— cast iron and steel respectively. The DuroMax XP12000EH has an impressive run-time of 10 hours on gasoline at 50% maximum output and 20 hours on gasoline at 50% maximum output. With up to 12,000 watts of power, this dual fuel generator will help you weather any emergency power outage.

This dual fuel generator is also equipped with practical and useful safety features. The main overload circuit breaker and individual circuit breakers for each power outlet socket helps to prevent any damage due to circuit overload or a short circuit. Once the power load has been corrected, the user can reset the circuit breakers. This dual fuel generator also comes with other common safety features like an oil level alert system to prevent overheating or damage due to running the engine on insufficient fuel, a spark arresting muffler to minimize sparks that are potential fire hazards, and a volt meter for you to keep a close eye on the voltage level and make sure that your appliances don’t get fried or spoilt due to over or under voltage.

As for ease of use, this dual fuel generator is functional without being excessive. The DuroMax XP12000EH has two regular 120V power outlets, a 120V 30 Amp twist-lock outlet and a 120V/240V power outlet.

Despite the weight, the DuroMax XP12000EH is still portable thanks to the accompanying transportation kit which includes wheels and handles. With the exception that it is non CARB-approved (it is EPA-approved), I would say that this dual fuel generator seems to be well worth your buck and its “weight”. It comes with a two-year limited warranty.

The DuroMax XP4850EH comes with a 7HP engine that is decent enough to help you run your important appliances (refrigerator, lights and other basic appliances) uninterrupted in the event of a power outage. This dual fuel generator can deliver a constant output of 3,850 watts and a maximum output of 4,850 watts. The 4-gallon fuel tank will give you approximately 8 hours of running time on half load.

Like the Champion 76533, this dual fuel generator set is also on the lighter side at a maximum of 130lbs. If you can afford to spend slightly more, this is a good alternative to consider for a dual fuel generator.

Best Dual Fuel Generator (IF YOU CAN SPLURGE – The ALTERNATIVE Option): Smarter Tools ST-GP7500DEB

If you have the budget, I would recommend the Smarter Tools ST-GP7500DEB dual fuel generator. Although this dual fuel generator is costly, you can tell that it is well worth the money based on its product specifications.

This is more than sufficient to power most of your household appliances like your refrigerator, your microwave oven, heater and even the lights. It has a 6.6-gallon tank. When filled to the brim, this dual fuel generator can run for 9 hours on gasoline at a 50% load or 7-8 hours with a 20lb propane cylinder. Some Amazon customers have also remarked that this dual fuel generator’s powerful 13HP 4-stroke air-cooled OHV engine lasted longer than normal motors in other power generators.

Smarter Tools ST-GP7500DEB does not compromise on safety features—it’s equipped with conceivable safety features that any user would want or need from a power generator. This dual fuel generator comes with overload protection which protects both the generator and your appliances.

One minor complaint from users was that this dual fuel generator can be quite noisy. Although this dual fuel generator comes with a quiet operation spark arrest muffler to reduce noise levels to 72db on full load, it is not one of the quietest dual fuel generators. And the noise level was generally acceptable to use.
