How to buy a Dual Fuel Generator

I have been on the quest for the best dual fuel generator. I realize one can easily get lost in the list of features all generators have.

So, I have used my experience and summed up important features which you should look for when sorting the best dual fuel generator.

Let’s dive right in… 

Performance

The performance of a generator is a very important factor to consider even if it doesn’t have Bluetooth control or another fancy feature. That’s what plays a major role when you are looking for the best generator.

The performance of the generator depends on many factors but fuel efficiency, power output, and run-time hours for a given gallon of fuel.

A good performance generator is beneficial for you in the long run by giving you better output and lower fuel consumption.

Safety

Safety is a necessity. All generators produce harmful gases and particles while running. One such gas is carbon monoxide.

Carbon Monoxide poisoning alone accounts for dozens of death every year. There are guidelines by EPA and CARB to reduce these emissions.

So, do look for EPA and CARB-certified generators. Also, take precautions when deciding where to place and run your generator.

Know Your Power Need

You should calculate how much power you need before setting out on the quest for the best dual-fuel portable generator. This will save you a lot of effort and bucks.

You would not like ending up with a generator with lesser power and then overloading it. Also, a generator with much more power than you need can be useless.

So, know your power need and check the maximum power and running power of the generator. This will help you make the best selection.

Important Features to Consider

Everyone’s use case is different. So, I have listed a few other important features which you might want to consider.

Automatic CO Shutoff & Low-CO Engine

Automatic CO shutoff technology detects CO levels and when it crosses the standards, the engine shuts off. This is important for protection from Carbon Monoxide(also called the silent killer).

A Low CO engine produces low Carbon monoxide which reduces any risk. CO sense and CO Minder are a few implementations of Automatic Shutoff.

Automatic Start

Automatic Start is a very important and luxurious feature. The latest generators have this technology. It starts the generator as soon as the power goes off. This feature is essential if you are lazy like me.

This feature might cost you a few extra bucks but will definitely add to your ease.

Electric Start

Pulling the recoil to start the generator has always been a headache. As the generator grows old it starts taking more effort to start with recoil. 

I have kicked my old generator out of frustration many times. Electric start and wireless start features save you from this hassle.

But again, will cost you a few extra bucks.

Fuel Gauge

A fuel gauge helps you keep track of your fuel level. My former generator lacked a fuel gauge. 

There were instances when we thought fuel was there but the generator stopped after a while as fuel was low.

Having a fuel gauge reduces the hassle to check fuel and you can keep track of fuel consumption too.

Low-Oil Shutoff

The engine can incur damage when running on a low oil level. The low oil shutoff sensor detects low engine oil and shuts down the generator when the fuel level goes nada.

This contributes to the long life of the engine and hence the durability of your generator.

Noise Level

The generators with bigger engines generate more noise when running on a good electrical load. This noise can become disturbing for you and your neighbors.

During emergencies and power outages, most people use portable generators. Believe me, you wouldn’t love to own the loudest generator of all your neighbors. 

Also, you might attract some uninvited complaints about loud noise. So, consider the noise level before buying an emergency generator.

Conclusion

All the above-reviewed generators are the best available dual fuel generators out there. The dual fuel option is insurance for cases when the access to gasoline supply gets disrupted.

Westinghouse WGen7500DF is our best choice for the dual-fuel portable generator of all the above power sources. It is an excellent portable option for all your emergency backup power needs, tailgating, and other outdoor plans.

Wireless remote start, Powerful output, brand support, and durability of this generator are some of the best features. This is a reliable and worth every buck generator from Westinghouse Outdoor Power Equipment.

Everyone’s use case is different so depending on your use case you can choose any of the generators from the above list.

As an example, if you need a generator for more heavy loads. DuroMax XP12000EH comes with plenty of power. It can be the one for you. So, just go for the one that suits best your backup power source needs.
