Portable generators are convenient solutions for power outages and emergency situations.
Regardless of where you live, how much square footage your home covers, or how much electricity you use on a daily basis, it is always smart to have a backup generator sitting around just in case you need that extra power.
Besides emergency situations, portable generators can be used for a variety of other purposes, including RV camping, outdoor activities, and construction work.
Whichever reason you have to look for a new portable generator, you’ve come to the right place to choose the right product!
Before we get into the actual reviews of portable generators available on the market, it is important to mention that there are different types of generators you need to keep in mind.
We won’t be mentioning any basic generators that run on a single type of fuel because those are the least effective machines out there.
If you want to get more bang for your buck, it is always better to go for a dual or tri-fuel generator. As you can guess by the name, dual generators can run on two types of fuel, whereas the tri-fuel generator allows extra flexibility where you can switch between gas, diesel, and propane.
Choosing the right generator for your needs might be challenging because there are so many different products out there. You can easily get lost in all the features and flaws thrown at you on the market.
That is why we took the time to do the research for you and present the best dual and tri-fuel generators currently available out there! All you have to do is read through the reviews and choose the generator that suits your needs based on size and power capabilities.

Best Dual Fuel and Tri-Fuel Generators Buyer’s Guide
What is the difference between dual fuel and tri-fuel generators?
Both dual fuel and tri-fuel portable generators aim to get the same job done – create backup electricity for homes, RVs, or emergency situations. The difference lies in the fuel types each generator uses.
As it is suggested by the very name, a dual generator is capable of using two types of fuel. These are the usual gas and propane. Tri fuel generators, on the other hand, allow you to switch and choose between three types of fuel.
Besides propane and gas, tri-fuel generators can run on diesel or natural gas, depending on the unit. Overall, dual fuel and tri-fuel generators provide more flexibility, which is necessary for emergency situations where you might have different types of fuels available.
Is it cheaper to run a generator on propane or gas?
If we look at this from a price point of view, gas is technically cheaper to obtain than propane. However, there are reasons to use both of these fuels, and here’s why! Propane is a cleaner gas that provides cleaner electricity.
This is a better option for your generator and for the appliances that you will be powering with this backup source. Being a clean gas, propane is also a lot lighter and better for the environment compared to gas.
However, it is also important to mention that propane is less efficient than gas, which means that gas can produce more BTUs per gallon, giving you more bang for your buck.
Propane is slightly more expensive if we compare the price per gallon. However, it’s not only the budget you should consider when making a purchase. Other factors such as the longevity of your generator and the effects on the environment should be taken into consideration as well.
How long will a 500-gallon propane tank run a generator?
On average, propane burns two to three gallons per hour. However, the consumption rates might differ depending on several factors, including the quality of fuel, your generator unit, and its condition, as well as the environment the unit is running in.
In an average situation, a 500-gallon tank filled with propane will run your generator for an entire week straight. Keep in mind that too demanding appliances such as air conditioners that require over 15 000 BTUs can drain the tank much faster.
It all depends on how much power you are going to be using. After all, it is not the same to power a small RV and to power an entire household.
Are tri-fuel generators prone to malfunction?
Naturally, many people assume that tri-fuel generators might be more prone to malfunction because of more complex technology and wider use of fuels. While this might make sense in some way, it is not entirely true.
In reality, a dual fuel generator has the same chances of malfunctioning as a tri-fuel unit. It’s not the fuel capacity that plays an important role here.
Whether or not a unit is prone to malfunction depends on other factors such as it’s manufacturer, how old it is, how well maintained it is, and what kind of conditions it has to handle while operating.
Even if a unit does malfunction, you don’t have to worry about it as long as it is covered by a warranty.
What size do I look for if I need a generator for home use? Should I get a dual or tri-fuel portable generator?
What size of a generator you need is one of the most common questions related to this topic. The truth is, there is no rule or a specific size of a generator that you need to purchase. However, you can adjust the size to your needs by looking at some of the major factors.
These include the size of your home, the number of appliances you are planning to power with a generator, the number of heavy load appliances such as air conditioners, as well as the overall purpose of the generator.
If you need a backup generator to supply your home with power during emergency situations, anywhere from 3 000 to 6 500 watts will be enough to cover your needs.
However, if you’re planning to use the generator for specific appliances or you’re planning to power a home for a longer period of time, consider going higher than 6 500 watts. Look back at our list of reviews, and you’ll find some extremely powerful generators with 10 000 watts of power.
