Dual Fuel Buyer’s Guide
With the increasing demand for cost-effective, versatile, and “cleaner” generators, dual fuel models were born. These generators are capable of using two different fuels to produce electricity.
Since there are many brands, makes, and models that feature dual fuel systems, finding the right generator can be quite tricky.
Now that you know the best dual fuel generators in the market today, we like to give you more tips and reminders before you purchase one. Below are the most important factors to consider when shopping for dual-fuel generators:
Power Output
How many loads your generator can support is dependent on its power output which is measured in watts. Generators produce two different outputs: the rated or running wattage and the peak or surge wattage.
The surge or starting wattage indicates the amount of power needed by a device to operate, while the running wattage indicates the power it needs to keep running.
If you’re using the generator for residential or commercial applications, opt for higher power output. Generators rated at 5,000 to 7,500 watts are ideal for powering household equipment and power tools.
Fuel Capacity
Apparently, the bigger the tank, the more fuel it can hold. A bigger tank is an advantage because it means you won’t have to refill too often. A higher fuel capacity also corresponds to a longer runtime.
Portable generators designed for camping, bowfishing, and outdoor use generally have smaller fuel tanks, while heavy-duty residential or commercial generators have larger tanks.
Choose a model with a decent fuel capacity that could provide at least 10 hours of continuous power supply.
Noise Level
Generators will never be super quiet, but you can find many makes and models with good noise levels. Inverter-style generators are the quietest, with noise levels ranging from 50 to 60 dB. A 60dB is comparable to the noise level of a normal conversation.
Keep in mind, though, that the dB ratings you see on generator specs are only applicable for 25% load. The higher the power output of the generator, the noisier it gets. So, it’s best to avoid generators that have dB ratings of 75 and up as they can be terribly loud.

Safety
Lastly, pay attention to the dual fuel generator’s safety features. Quality generators usually have overheating and overload protection. Some models automatically shut down when the gas or oil runs low.

5. Can a Propane Generator Run on Natural Gas Without Modification?
Modifications are easy with natural gas conversion kits.
Final Recommendations
All the five dual-fuel generators highlighted above are the best in their class, but we’d like to give the top spot to Pulsar G12KBN-SG 12000 Watt Generator.
It offers plenty of advantages for homeowners and job site operators. With 9,500 running watts, you can run most of your household appliances. We would have chosen the Westinghouse WGen7500 had it not been for its high THD.
Despite its high capacity, the Pulsar G12KBN-SG 12000 Watt Generator has a THD ranging from 5% to 8%. That means it provides “clean” electricity, and you can safely connect sensitive appliances and electronics to it. Since all of us are using devices like laptops and computers, this feature is a major concern.
That said, if you’re looking for a portable option for outdoor and recreational use, we highly recommend DuroMax. This dual fuel generator isn’t the lightest but comes with features like a wheel kit and handles for easy transportation. The decent power output is the biggest selling point for us.
Aside from your RV travels and camping trips, you can use it as an emergency backup power source for your home. Such versatility makes this generator worth the investment.
