Best Tri Fuel Generators Buying Guide


The generator is a one-time investment. So, you should not decide in a hurry. Every product has some pros and cons and different specifications. You need to analyze everything deeply before reaching a decision. There are many types of tri-fuel generators available in the market. They’ll probably confuse you. You need to choose according to your requirements and home needs.


Find out if the tri-fuel generator works for you or not. These generators are typically heavier and more expensive compared to dual-fuel generators. Is it getting complicated? Do not worry; we are going to explain some pro tips. These will help you to get the best generator available in the market.


Wattage and Engine

The first thing that you should check is the surge and continuous watts of a generator. It doesn’t matter whether you want to buy a traditional generator or a tri-fuel generator.


Continuous wattage means the amount of wattage that a generator can run continuously. However, surge wattage means the wattage that a generator produces when you start it. Surge wattage is the power that the generator produces in only 2-3 seconds.


You need to check this wattage before buying a generator. Besides this, check what kind of appliances you are planning to run on a generator.


For example, a motor requires more power to start than to run it continuously. That’s why surge and continuous wattage matter a lot.


AVR system

Automatic Voltage regulation is another factor that must not be ignored when you check the features of a generator. It is very necessary to have an AVR system if you want to power sensitive devices. It protects you from damage.


Fuel tank capacity

Fuel tank capacity matters when you run a generator on gasoline. Because propane will come with its tank and natural gas will be supplied through the pipeline. Some good generators provide 7-gallon to 15-gallon fuel tanks. However, it depends on how often you fill the fuel tank.


Power Outlets

It is better to select a generator that has more power outlets so that you power most of your home equipment. Most generators have four household-style 120V outlets. These outlets are used to power most home appliances. However, some generators also have USB charging ports.


Safety Features

Your safety comes first. Do not compromise on it. Always buy a generator that has a low oil shut-off feature. It will help you to protect your engine and home appliances.



Some generators do not come with wheel kits, batteries, and other important generator accessories. In this case, you’ll have to buy these accessories separately. It’ll put an extra burden on you.



The generator is an investment that will last many years. So, it is wise to check the warranty of a product that you are going to buy. Some manufacturers offer limited warranties. However, a few of them offer a maximum of three years of warranty. But be sure to check what type of issues they will cover during the warranty period.


Additional features

Suppose you are environmentally conscious and care about air quality, you need to check whether a product is carb-compliant or not. lets it is not, you can’t operate the product in California. If it is CARB-approved, it is a plus point of a generator. Besides this, check the customer service of the brand. Check if their customers are happy with the service and product. This will help you to choose the best possible product.
