What to Consider While Buying Dual Fuel Portable Generators


If you are willing to buy dual-fuel portable generators, the first thing you must consider is the performance.

There are different brands and manufacturers. Each company comes up with different models with different features in it.

You must identify your required performance and then look for the generators that match your expectations. In that case, you have to take a look at the design and the used materials as the performance of the generator depends on the design and the materials that are used in it.


Portability is another important thing that you must consider while buying an inverter generator. There are some generators that pretty much everyone can lift, but there are always some ordinaries in everything.

Some companies manufacture really heavy generators which are pretty good in quality. But for the heavyweight, the consumers don’t intend to purchase those.

If you want to use the inverter for your RV, you will definitely want to purchase a lighter one.

You won’t want your RV to be filled up with heavy instruments that can make it difficult to bear the weight.

Also, lightweight portable dual-fuel generators are suitable choices for camping or tailgating parties.

Safety and Noise Level

You must consider the safety features before purchasing an inverter generator. You must check if the generator is EPA and CARB-compliant or not.

You must need this certificate to generate the inverter inside California as the law is tougher here. Also, there are some generators that don’t contain spark safety which can lead to a major accident.

Noise level is one of the most important criteria you need to consider before buying a generator.

You surely don’t want to make your neighbor annoyed with the loud sound of your generator. And a loud noisy generator is enough to spoil your camping experience.

Power Output

It’s an obvious fact that we all look at the power output before buying a generator. The power output of the generator depends on the starting watts and the running watts.

For buying a good generator containing good backup power, we must look into the requirement first. The necessity of the power output differs according to the purpose of use.

You need a particular amount of power backup if you want to use it for your RV, you need another in case you want it for home or camping. So choose the ideal one that matches your requirement.


Last but not least. Undoubtedly, budget is the key to any purchase. We have many expectations but fail to achieve them for money.

In the case of purchasing a generator, money is the most important thing you need to have a good experience with a good quality inverter.

However, in many cases, you don’t need a huge amount of money if you need a smaller generator with a moderate power outage.

Advantages of Dual Fuel Generators

Reliability and Dependability

Dual fuel generators are famous for their advanced technology and suitable design. They are eligible for being operated with both gas and propane. The versatile usability and flexible functions made these inverters the best of both worlds.


For heavy power output and safety using these dual fuel generators are unique and exceptional as they produce pure sine wave which is a must-needed feature for running sensitive electronics safely.

Also, the OHV engine of dual-fuel inverters generates clean power with very low fuel consumption. While choosing a generator, it’s mandatory to consider the usability, functionality, and quality to maintain a good experience with an ideal generator.


Most of dual-fuel generators are highly equipped and heavily designed. Most of them come with metal steel frame structures which allows them to be steadfast in any kind of natural disaster or harsh condition.

The strong and sturdy structure also works to reduce vibration and noise.

Easy Switching Between Fuels

In an emergency, you can change the fuel type according to your wish. You might not get one of the fuels near the location you want to run a generator in. you can get your work done with the other one.


You will find the dual-fuel generators cheaper and more affordable compared to the other inverter generators. Also, dual-fuel generators give you the flexibility of using two different fuel types. You can use any of these two according to your budget.

Disadvantages of Dual Fuel Generators

There are so many advantages of dual fuel generators. But everything has some disadvantages to make the proverb true, “nothing is perfect.” There are some disadvantages of dual-fuel inverter generators.

Most dual-fuel generators are a little bit heavier compared to conventional generators. They also make a lot of noise.

That apart, the design of dual-fuel generators is suitable for heavy use, so it contains a larger fuel tank and control panel which make them more elegant and cost a little more money. There are some more disadvantages of dual fuel inverter generators for RV.

Environmental Footprint

Propane and gasoline are a great cause of destroying the air atmosphere and these gases are one of the reasons for the greenhouse effect.

So dual fuel generators lose one point here for being a risky product for the environment.

Carbon Dioxide Emission

This is a known fact that most generators eject carbon dioxide while operating. Dual fuel generator is not different from them. But one thing which is special about these products is you can control the amount of emission of carbon dioxide. The maintenance of these generators is very easy.


The more feature it has, the heavier it gets. As dual-fuel generators contain bigger fuel tanks and some other important features, these generators are quite heavy compared to camping generators. Other than that, these are much lighter than home generators.
