Best Dual Fuel Generator Review

Generators come in real handy during tough weather conditions like heavy storms, rains, and hurricanes. Such extreme situations can lead to power outages, leaving you in darkness.

Your best bet in such times is a generator. However, there’s a bit of a problem with conventional generators. They mostly operate on gasoline which can be a bit difficult to obtain and is also a bit expensive. Fortunately, there’s a solution to this problem and it comes in the form of dual generators.

Dual generators are a bit different than standard generators. They give you the option to choose between two fuel types: gasoline or propane.

So, without wasting any time, let’s have a look at some of the most efficient dual fuel generators on the market:

Why Choose Dual Fuel Generator Over Single Fuel?

It’s always good to have options. Believe it or not, there are some regions where gasoline is more expensive or more easily available than propane and vice versa.

Having a generator that lets you choose between two options puts you in a great place as you can pick one that you can easily get your hands on, especially in tough situations where access to fuel is limited.

Which Fuel Type to Use?

Propane is cheaper and easily available while gasoline can be a bit expensive and hard to find.

Apart from that, propane is safer for the environment as it emits less harmful gases when compared to gasoline.

Other than this, consider your regional temperature as well when choosing a fuel.

Gasoline might be a cheaper option but it is consumed very quickly. This is because heat makes it evaporate faster. Hence, it may not be suitable for very hot regions.

Similarly, living in a colder region can be a bit problematic for people who are thinking of using propane. This fuel begins to contract below 40 degrees. Hence, it may not be suitable for very cold regions.

Best Dual Fuel Generator Buying Guide

Now, the question is how to choose a dual fuel generator that offers plenty of features and is suited as per your needs.

There are a number of products on the market, hence picking one can be quite a challenge.

To make it easier for you, here are a few factors you should consider when selecting a dual fuel generator:

  • Regional Temperature: Believe it or not, your regional temperature can make a lot of difference when selecting a generator.

    First of all, some generators do not start well in winters as the engine may get frozen. This is why for very cold areas, you should go for a generator like Champion 7500-Watt Dual Fuel Portable Generator with Electric Start. Its cold start feature ensures you have no problem in turning it on even when it’s snowy outside.
  • Power: This is a no brainer. Generators offer limited power, hence you must know exactly how much power you need so that you can pick the right generator.

    As a rule of thumb, appliances that involve heating or cooling (ACs, refrigerators) require a lot of power. If you want to run such appliances, you will need to go for a unit that provides at least 5000W of power, such as Pulsar 5,250W Dual Fuel Portable Generator with Switch and Go Technology.

    It’s a powerful generator that is made to run almost all home appliances.
  • Types Of Appliances You Want To Run: This is important to ensure all appliances can run without any trouble.

    You have to pay attention to two features: outlets and the sensitivity of appliances. Some appliances, such as laptops, are sensitive and require continuous power as fluctuations can be bad for them.

    We suggest you go for Powerhorse Dual Fuel Generator 9000 Surge Watts if you want to run a variety of appliances including sensitive appliances.

    It produces a total harmonic distortion of less than 5% and offers 10 connectable outlets, making it suitable for a variety of uses. Plus, you can even use it outdoors and to run RVs.
  • Safety: Some of the most common safety features you need to look into are: low oil indicator, voltguard protection, voltmeter, and overheating protection. These features are not only important for the safety of generators and other appliances, but also for the safety of your family members.

    They ensure the generator shuts down automatically if anything goes wrong, so be sure to look for these features when picking a dual fuel generator. Champion 3800-Watt Dual Fuel RV Ready Portable Generator can be a good choice as it’s safe to use and is also environmentally friendly.
  • Noise: Pay special attention to this factor as noisy generators can be a pain to handle. While big generators tend to be noisy, some now come with mufflers and other features to suppress the noise so pay special attention to such features.

    Anything under 40 dB is said to be acceptable as it only equals to slight whispering but generator above 50 dB can be very noisy.

  Every 10 dB increase means the generator is ten times louder. Here’s a small breakdown:

Noise Level (Decibels)

Sound

​20dB

​Rustling Leaves

​30dB

​Whisper (5 meters)

​40 dB

​A bunch of people having a conversation at a distance.

59dB

Constant laughter

​60dB

​People talking right behind you

​70dB

​Vacuum Cleaner

​90dB

​City Traffic

​110 – 120dB

​Night Club / Rock Concert

  • ​Price: Heavy duty generators will obviously cost more than low-powered dual fuel generators. If you wish to run a few appliances then you won’t need to spend a lot of money and can get a small to medium ranged dual fuel generator.

    However, if you wish to run heavier appliances and lots of them then you will need a heavy duty generator like DuroMax Hybrid Dual Fuel XP12000EH 12,000-Watt Portable Generator. It is quite powerful and offers excellent run-time as well.

Best Dual Fuel Generator: FAQS

Q. Is it wise to charge sensitive electronics using a dual fuel generator?

Ans. Sensitive electronics aren’t able to withstand voltage fluctuations and may easily sustain damage. To avoid your delicate electronics from burning up, make sure to choose a generator that offers clean energy.

Some generators use sine wave technology and have features to prevent fluctuations.

Q. How can I lower the noise of a loud generator?

Ans. While it won’t make a lot of difference but keeping them elevated can help. This is because generators vibrate on the ground and produce more sound. Keeping them above the ground will minimize noise.

Apart from that, buy an extension cord and place them at a considerable distance for additional safety.

Q. Can I use dual fuel generators outdoors?

Ans. Yes, depending on the make and model. Many dual fuel generators are perfect for outdoor use.

The Bottomline: 

These were some of the best dual fuel generators that you can opt for. Make sure to identify your needs first and then choose the right one.
