What is a Tri-Fuel Portable Generator?

A generator is a device that makes it possible to have electricity in places without access to a power grid. These devices can receive power from many different possible fuel types.

A tri-fuel portable generator can use either gasoline, natural gas, or propane to generate electricity. With three different possible power sources, a tri-fuel portable generator makes it that much easier to stay connected to electricity wherever your adventures take you.

Most Common Issues People Have with Tri-Fuel Portable Generators

• Weak Links: A tri-fuel portable generator will ideally provide three different power sources of equal efficiency and cost. This isn’t always a realistic expectation, though. It is common for certain fuel types to work better and more efficiently than others.
• Too Loud: When you power up a generator, one of the most common concerns people have is with the level of noise. A responsible manufacturer will typically understand this, and will clearly indicate how many decibels of noise that their generator creates.
• Too Expensive: Nobody said that getting a tri-fuel portable generator was cheap. Many people get excited about the benefits of having a tri-fuel portable generator only to be let down by the prices. If you want a good tri-fuel portable generator, be ready to pay a fair price.

What Are The Best Selling Tri Fuel Portable Generators?

Comparing Our Favorite Tri-Fuel Portable Generators

1. WINCO HPS12000HE 360 – Best Overall

No products found.

Although the WINCO HPS12000HE 360 is a bit bulky, this tri-fuel generator is CARB-approved and EPA-certified to use regular gasoline, natural gas and liquefied petroleum gas (LP).

True Honda Heart

Its supreme output comes from its powerful Honda GX630 688cc OHV engine that generates 10,800 watts of continuous current and 12,000 watts of surge power. This amount of surge power is good for running power tools, or as a home backup generator.

Unfortunately, the generator’s output is not enough to power a six-member household on its own over a longer period of time. If this is your case, maybe you should consider some backup options.

Designed For Versatility

This tri-fueled portable generator can power everything from sump pumps, water pumps, TVs, air conditioning units, and furnaces only to name a few.

The HPS12000HE has an electric start, which makes it easy to get cranked up. It generates a current of 120V and 240V AC. This means a continuous current rating of 90/45 amps.

Full Receptacle Package

This is a full receptacle package that includes a circuit breaker. It can run for 14.5 hours at half load capacity and has nine hours runtime at full capacity.

Noise

One of the few drawbacks of this model is that it is pretty loud. Albeit having two wheels to be hauled around on, considering its substantial weight it is almost like pulling around a 500-600 cc motorcycle. We were also surprised to find out that the warranty is only for 90 days.

Super Lightweight

This Sportsman tri-fuel generator only weighs in at a little over 90 kg, which isn’t bad for the size of its engine. The Sportsman offers a two-year limited warranty on CO2 emission levels and a one-year limited warranty on manufacturing and some parts.

4. Honda Tri Fuel Generator – The Most Durable Tri-Fuel Portable Generator

In addition to being a top car-maker, Honda is also known for their super durable and fuel-efficient generator engines. This Honda tri-fuel generator provides you with the precise voltage control yield, whenever you may need it.

Tireless Honda Heart For Ultimate Performance

Its heart is a 13hp Honda engine that is paired with twist outlets for flexible power supply. In addition, the engine is actually a gx390 OHV that comes with a recoil start for many flawless ignitions.

Good-Size Tank

5. Smart Generators Portable 8400B Tri-fuel Generator – The Best Powerful Multi-Fuel Generator

No products found.

The Smart Generators SG8400B is touted to be one of the most powerful generators on the market. With two less horsepower than the Sportsman model, this tri-fuel generator pushes out an amazing 15,000-watts surge power and an average 8,400-watts of continuous running power.

Tremendous Output

With 15,000-watts of surge, you can bet your last dollar that you can power nearly any large appliances or power tools you want. With all of that power, it can run for 12 hours at half capacity on eight gallons of gas (that being a full tank).

Running it on propane, the SG8400B can run an amazing twenty hours at half capacity. Power output for natural gas decreases by 20 percent, which isn’t something unusual for tri-fuel generators.

Ultra Lightweight

This bad boy only weighs in at just over 90 kilos. The noise level is at the bearable 75 db. Since most of these types of generators do not come encased, you really can’t get around the noise level.

Unclear Certification

Please keep in mind that for the time being it is not clear whether or not this particular model is EPA and CARB certified. We are not saying it isn’t, only that it isn’t clear from what we researched.

Outlets

It comes with four 120-volt 20-amp outlets and one 120/240-volt 30-amp twist outlet.

Extras

It includes battery and charger, along with wheel kit. You would probably have to assemble the wheel kit yourself if you ordered it online, rather than purchased it from a dealer that would usually assemble these things for you.

2-Year Warranty

This model also comes with a two-year limited warranty. Nevertheless, it doesn’t specify exactly what the warranty covers. It is our assumption that it most likely covers certain parts and craftsmanship.

Features of the Best Tri-Fuel Portable Generators

If you want to get one of the best tri-fuel portable generators, there is a certain degree of background research which is required. You don’t want to make a purchase you end up regretting. To help you out, here are the top features we find in top-quality tri-fuel portable generators.

Efficient Fuel Use with Plenty of Runtime

As you should know, any sort of portable generator doesn’t provide free electricity. For this reason, it’s important to consider how efficiently each of your top options uses their fuel sources. Find a model which both uses fuel efficiently and is capable of lasting long enough for your needs on a full tank.

Bearable Volume Level

As a general rule of thumb, noise levels, which reach above 85 decibels can cause permanent damage to your hearing. A typical human conversation, on the other hand, will be around 65 dB.

Keeping this information in mind, any of the best tri-fuel portable generators will have noise-reduction features which keep the decibels at a safe level. Typically, this will be anywhere between 50 – 75 dB.

Easy Oil Changes

Just as you need to routinely change the oil on a car, so too will you need to change the oil on your tri-fuel portable generator. There are certain models like the Motorhead Tri-Fuel Generator which are designed to provide a near-automatic oil change experience.

It is also common for generators to automatically shutdown when oil levels are too low. If you consider the process for oil changes now, you will be less likely to encounter problems down the line.

Lots of Power & Available Outlets

Generators are expected to provide power for both small and large events alike. Depending on your needs, you will likely purchase a model, which can at least support 8,000 watts of continuous power.

For large events or people with larger power needs, anything right around 10,000 watts will likely be enough (generator options here). There should also be more than one available outlet so that you don’t need to break out multiple power outlets and risk your safety.

Reasonable Price with Plenty of Versatility

Your goal shouldn’t be to necessary find the most affordable tri-fuel portable generator. Especially if you are concerned with the quality and durability of the product.

Start by considering which features matter the most to you. Then find the tri-fuel generator which best meets your budget and needs.

Factors To Consider When Buying A Tri-Fuel Portable Generator

The purchase of a portable tri-fuel generator is an important decision to make. Below are some of the factors to think about before setting off for the nearest dealer.

1. Noise Reduction Capability

Most of the bad boys reviewed above are pretty noisy. As you are looking for your ideal tri-fuel generator, make sure that it has some noise reduction features and capabilities to offer its owner.

To check the noise level generated by your portable tri-fuel generator, make sure to have a good look at the decibel levels indicated on the label. A bearable noise level that you can have would range from 50 to 70 decibels.

2. Fuel Capacity

One of the important factors to consider while you are looking for your perfect tri-fuel generator is its fuel capacity. In this regard, simply think that a bigger fuel capacity would mean more fuel to burn thus generating more power for longer hours of use.

Of course, while considering the generator’s fuel capacity, you also need to consider the specific purpose your generator will serve. Try to answer the following questions: Will you be providing power for a whole house full of numerous household appliances and many electrical devices? Or will you just be providing power for a few devices over a short period of time?

3. Fuel Efficiency

Of course, since every tri-fuel portable generator is powered by some sort of an engine, you would want one offering maximum fuel efficiency. In this respect, make sure that the engine is designed to make full use of the fuel without wasting a milliliter.

A good way to check out the fuel efficiency of your generator is the volume of CO2 emissions that it emits. The more fuel-efficient models tend to emit less exhaust gases, but they usually sell at higher retail prices. But if you feel like you don’t need a tri-fuel type of generator, you can choose which of these best pulsar generators will fit your needs.

4. Price

As with almost anything that you buy in the market, you should always check out the price. When it comes to portable tri-fuel generators, bigger would usually mean pricier. A good way for you to save some of your money is make a list of the features you need your machine to have.

5. Maintenance And Service

Since a portable tri-fuel generator is made up of different components, it will require constant maintenance and regular checkups. In this line of thoughts, you’d better make sure your generator comes with maintenance features which can ensure its long service life.

Also, not all people know their way around fixing their generators in case technical problems and issues arise. Make sure that your generator has a local service provider in your area, so as to avoid unnecessary transportation costs. The last thing you want is to ship your generator back for repairs.

Ready To Buy The Best Tri-Fuel Portable Generators?

For many years now, portable tri-fuel generators have constantly been improved and the premium models reviewed above boast a wide array of features and benefits. As its very name suggests, a tri-fuel generator can run on not one, not two, but three different fuels.

A tri-fuel generator is an excellent thing to have if you live in the bush, or in an area with unstable power supply. Last but not least, the chances are that your local gas station will hardly ever run out of all three types of fuel that your machine runs on.
