Reviews : Champion 100416 vs DuroMax HXT — Best Tri-Fuel Generator

A tri-fuel generator is quite a novel concept. I’m sure not too many folks are aware they even exist. Hybrid generators have become common. Most of us know a bit about dual-fuel generators. These can run on propane or gasoline, making them very convenient. An obvious question, I’m sure many of you are asking has to be: What is a tri-fuel generator?A tri-fuel generator is quite a novel concept. I’m sure not too many folks are aware they even exist. Hybrid generators have become common. Most of us know a bit about dual-fuel generators. These can run on propane or gasoline, making them very convenient. An obvious question, I’m sure many of you are asking has to be: What is a tri-fuel generator? Don’t worry, we’ll answer that. Actually, it’s a quick answer — a tri-fuel generator is capable of being powered by 3 different fuel sources, typically the fuel sources are : Gas, Propane and Natural Gas. In this article we review the the Champion 100416 (see image above).

Tri-fuel generators are hybrids with even more convenience, as they can run on gasoline, propane, or natural gas. There really aren’t too many options when shopping around for a tri-fuel generator. When the Champion 100416 first came out on the market it was easily the best tri-fuel generator for domestic use, and also the most affordable. But, things changed in 2023 when DuroMax released their first tri-fuel generator (XP13000HXT), with everything you could want in generator, such as more power, longer warranty, a 50A outlet and more. We have a comparison between these two generators in this article. You might be surprised as to how they stack up.

Most people are quite familiar with Champion dual-fuel generators, they have the most extensive range of hybrid dual-fuel generators on the market. It seems logical that the Champion 100416 would be a natural first choice for so many who already trust the brand and the extensive research they’ve conducted into this technology.

Other tri-fuel generator options include the Firman T08071 and the pretty expensive, but hugely impressive, industrial grade Winco HPS12000HE — and now we must include the latest competitor from DuroMax (XP13000HXT). There are also tri-fuel conversion kits available for popular generators, like the Honda EU2200i. We’ll be reviewing the Champion 100416, along with the other tri-fuel generators, and the best tri-fuel generator conversion kits.

Because many of you are heading into the unknown when deciding whether it’s a good idea to buy a tri-fuel generator, I’ll start with some background. Gaining an understanding of this technology will help you consider the pros and cons of tri-fuel vs dual-fuel vs gas only generators. You should be able to decide, with confidence, if you want to buy a tri-fuel generator or convert your existing generator to accommodate a tri-fuel setup.

Tri-Fuel Generator Technology

Because many of you are heading into the unknown when deciding whether it’s a good idea to buy a tri-fuel generator, I’ll start with some background. Gaining an understanding of this technology will help you consider the pros and cons of tri-fuel vs dual-fuel vs gas only generators. You should be able to decide, with confidence, if you want to buy a tri-fuel generator or convert your existing generator to accommodate a tri-fuel setup.

How does a Tri-fuel generator work?

The basic idea behind tri-fuel technology is not too far removed from the original technology used for dual-fuel generators. A key component is the carburetor adapter which supplies propane (LPG) or natural gas directly to the carburetor, bypassing the conventional gas pipe. A switch-over valve is used to change to the different types of fuel.

Propane and natural gas (methane) are completely different fuel types. Propane is heavier than natural gas and has more energy. The air to fuel ratio is different for each type of gas and they operate at different pressures.

In order for a generator to function using either propane or natural gas, it needs two pressure regulators, an “on demand” regulator, through which both propane and natural gas are supplied, as well as a low-pressure propane regulator.

Tri-fuel generators, like the Champion 100416, will have 2 fuel selectors, like a dual-fuel generator. One allows you to select either propane or natural gas, with separate inlets for each type of fuel. Another selector, usually a staring dial, is used for standard gasoline or the selected alternative fuel (natural gas or propane). The kit should include pipes and connectors for both propane and natural gas. You turn the dial to the fuel type you’re using, and the configuration will be automatically selected for gasoline, propane, or natural gas. A tri-fuel conversion may not always have the same convenience, though the basic components will remain the same.  

Benefits of using a Tri-Fuel Generator

Natural gas has been a popular choice for permanently installed standby generators for many years. If you’re using a portable generator to supply backup power to your home, a tri-fuel generator is about as hassle-free as it gets.

When you connect the generator to the natural gas supply to your home, you have a constant fuel supply. You don’t have to worry about storing gas, which has a limited lifespan. You’ll never experience the frustration of running out of gas or discovering, only when the power fails, that you forgot to fill the generator with gas.

Natural gas is often the most affordable, being cheaper than gas and propane in many areas.

Of course, because the generator isn’t restricted to only one type of fuel, it can still be used elsewhere. When you go camping, it’s unlikely that you’ll be able to use natural gas. It’s wonderfully versatile to be able to switch to gas or propane when away from home.

Both propane and natural gas burn cleaner than gasoline. This means lower emission levels. You will also be spending less on generator maintenance as the spark-plug and emission control system are less prone to carbon buildup which shortens their lifespan.

Using natural gas and propane is not all good news for generator users. Neither of these fuels have the same energy as gas. This means that power output is lower when using natural gas and propane.

Review : Champion 100416 / Best Value Tri-Fuel Generator

Features :

OVERVIEW —

Champion generators have recently undergone an extensive facelift, with a newly designed user panel and some upgraded features. The Champion 100416 has the best of all the new additions that have been incorporated to the range of Champion portable generators. I’ll be discussing these through the Champion 100416 review.

Because this is a tri-fuel generator, it has a long list of power specifications. Most of you are probably aware that portable generators don’t produce the same wattage when comparing output on gas to propane. Natural gas has an even lower output compared to propane. It has less kilojoules and, therefore, produces less energy.

Using gas, the Champion 100416 is a mighty powerful generator, with a peak output of 10,000 watts and 8,000W continuous power output. Connecting the generator to a propane tank, the power is reduced to 9,000 starting watts and 7,200 running watts. Natural gas takes this down to 8,750 starting watts and 7,000 running watts. The great benefit of limitless runtime, when using natural gas, is offset by a 1,250W reduction in surge power capacity and 1,000 watts off your running power, when compared to gasoline. Though even at the lowest power output, this generator can supply a refrigerator (or two), a fairly large air conditioner, and all your smaller appliances. The peak power supply should prevent the generator from tripping when several high-output appliances start simultaneously.

The Champion 459cc engine has proven to be a pretty reliable workhorse with ample power for a generator of this size. This is a low-emission, CARB compliant engine, and is remarkably fuel efficient. With the 8.5-gallon gas tank full, you can expect about 12.5 hours runtime at 50% load. This means an average power consumption of 4KW, continuously, for over 12-hours. For most homes, you could easily run the generator for up to 15-hours (possibly more) without needing to refill the gas tank. Certainly very convenient.

Champion Power equipment specify a runtime of 5-hours for the Champion 100416 when using propane. They don’t, however, mention what size propane tank will provide this runtime. I think it’s reasonable to assume that this refers to a 20 lbs. propane tank. You can obviously increase propane runtime by using a larger tank.

Another great addition to this generator is the CO Shield technology. This seems to be an increasing trend in generator safety. That’s a good thing, for sure. Because of the CO poisoning hazard that accompanies the use of a portable generator, several manufacturers have developed a warning and shutoff safety feature that ensures you and your family are kept safe from this danger. The generator will shut down when CO levels become dangerously high. The Champion 100416 is ANSI/PGMA G300-2018 compliant. This is the highest standard set by the Portable Generator Manufacturers Association for the monitoring and control of Carbon Monoxide level shutoff safety system for portable generators.

The new look control panel on the Champion 100416 is really great and wonderfully practical. It features plastic covers for all the electrical outlets, improving safety and durability. It keeps dust out and does a lot to prevent moisture from being a hazard. The natural gas and propane inlets also have safety covers when not in use. The push to reset circuit breakers are covered by water resistant plastic covers, even more safety for outdoor operation. Even with all this protection, I should point out that, like any generator, the Champion 100416 should not be operated in wet conditions. The safety features are there to prevent light moisture from being a hazard. This does not make it safe if used out in the rain or when it snows.

A selector dial, at the back of generator, allows for easy switching from propane to natural gas. A backup recoil starter is fitted just below this dial. On the front panel, a large control dial makes for the simplest staring. Turn the dial in one direction, and the gas supply from the tank opens, the choke is engaged, and you can press the start switch for the electric starter. You then turn dial further along to the normal run position when the engine is warm. If you’re using propane or natural gas, you perform exactly the same procedure, by turning the control dial in the opposite direction. Everything is clearly marked with easily identifiable color icons. Throughout, inlets and controls for natural gas are blue, with a distinctive gas flame icon. Propane systems are marked in green, with a propane tank icon. All gas controls are marked by the familiar gas pump icon on a red background. You don’t need to be a genius to figure things out.

The Champion 100416 generator has no DC outlets, which is not a big deal for home power. For camping, I would prefer to see a 12V DC leisure battery charging port, but this is not a huge disappointment. AC outlets are plentiful and ultimately convenient. You have an L14-30R (30A 120V/240V) outlet, making this a great generator for hassle-free home backup power. This allows for quick connection to a transfer switch, which will supply power directly to your electric panel. It also has a 120V, 30A (L5-30R) outlet, as well 4 X 120V 20A (5-20R) receptacles. The household 5-20R outlets include GFCI protection, making this an OSHA compliant jobsite generator.

The Intelli-Gauge, digital display has become a common feature on all range-topping Champion generators, the Champion 100416  is no exception. This is a 4-didit LED screen that provides quite extensive operating information, like maintenance intervals, output wattage, voltage, frequency, and two runtime logs (session time and lifetime running hours).

An 8,000/10,000 watt generator is a heavy machine, at the best of times. When we add extra components for multi-fuel operation, the weight is increased even further. Top this off with a strong, wrap-around  frame with impact protection, and a large metal gas tank, it’s inevitable that you’ll end up with a hefty beast. Given all these factors, the weight of 207 pounds comes as little surprise. As we would expect, when a generator is this heavy, the Champion 100416 is equipped with a large 10” solid wheel kit. Additional items include high-quality gas hoses for propane and natural gas, with an NPT adapter for natural gas hose.

Another unavoidable drawback is noise. This is an open frame generator with pretty large engine. This means a sound level exceeding 70dBA. I’d suggest an insulated generator enclosure which will reduce the noise and keep it safe in rain and snow.

The Champion 100416 must definitely come as great news for homeowners wanting a portable generator that can supply just about all our domestic power needs and run on a natural gas supply. Not to mention a very affordable option. Versatility is the name of the game here. With tri-fuel capabilities, the Champion 100416 is as useful in a campsite and or jobsite. Although Champion Power Equipment is not recognized as a heavy-duty industrial generator brand, these guys have a stellar reputation in the affordable domestic generator market. The 3-year warranty is a cut above the norm for this class of generator. Undoubtedly excellent value for money.

OVERVIEW —

Like the Champion 100416, this is one of the most affordable tri-fuel generators. While I’m inclined to rate the Champion model as the better generator, the Firman T08071 and Champion 100416 are very similar in just about every way. It really comes down to brand preference, which might be viewed as the best cheap tri-fuel generator.

When it comes down to a basic analysis of the Firman T08071 vs Champion 1000416 there is little to differentiate the two generators. Power output is the same; 10,000 watts peak power and 8,000 running watts. Though the carburetor converter fitted to the Firman generator is not as efficient as the one used on the Champion 100416. The Firman T08071 is actually quite dismal when running on natural gas, with only 6,900W surge capacity and 5,500W running capacity. Ironically, this generator fares slightly better than the Champion competitor, when comparing output capacity using propane. The Firman T08071 generates 50 watts more peak and continuous power when using propane – 7,250W/9050W.

The engines used for these two generators are very similar. Both are, in my opinion, better than most medium-duty generator engines. The Firman 439cc engine is slightly more fuel-efficient, providing a very convenient 12.5 hours runtime at 50% load from an 8.5 gallon gas tank. The Firman generator is also about as loud as the Champion 100416 at around 72dBA to 75dBA. This is a CARB certified generator with excellent emission levels.

While the Firman T08071 control panel is plastic (I prefer metal), it is just as comprehensive as that used for the Champion 100416. This generator has no DC power outlets but has the full array of AC receptacles, all with protective plastic covers, winning a few points in my book. It has a duplex 120V 20A (5-20R) outlet, a 120V 30A (L5-30R), and a 120V/240V 30A (L14-30R). Something that sets this generator apart from the Champion tri-fuel model is the inclusion of a 50A 120V/240A (14-50R) outlet. This is a bit of an advantage, as peak output at 240V is just over 40A. Though your maximum running load is 33A, only 3A more than the specified load for the L14-30R outlet.

Connecting gas hoses and operating the Firman tri-fuel generator is a breeze. It has high-quality brass fittings for the natural gas and propane hoses, with a switchover valve to select the type of fuel you’re using. Like the Champion 100416, this generator has an easy to use single action dial to supply fuel and activate the choke. A push-button electric starter makes the whole procedure quite effortless. You also have the reassurance of a recoil starter when the battery is not properly charged. Basic information is displayed on an LED digital screen.

The Firman T08071 is fitted to a strong frame with plenty of impact protection in the form of plastic panels. It weighs a little more than the Champion 100416 at 212 LBS. The 5” wheel kit is okay for a relatively flat surface. If you’re going to be hauling your generator over rougher terrain, like gravel, the 10” wheels fitted to the Champion generator will make things much easier. The U-shaped handle is really cool and helps a bit in managing the weight of this generator.

For those in the market for an affordable tri-fuel generator, the Firman T08071 is a good option. My preference for the Champion brand may be just a personal thing. It does, however, make the Firman generator my second choice. Objectively speaking, there is little difference between the two generators. If you’re going to be using the generator connected to a natural gas supply, the Firman T08071 could be a bit of a limitation as it does not have the best power output when running on natural gas. For the rest, it compares very well to the Champion 100416, with the same 3-year warranty. I guess the final decision may come down to price. You may well find yourself buying whichever of the two generators is cheapest.

OVERVIEW —

Now we’re talking my kind of generator. Funny thing, isn’t it? My favorite machines are always the most expensive. I guess it’s easy to pick the very best when reviewing the generator instead of actually paying for it. One thing that has me sold on the Winco tri-fuel generator is the absolutely tremendous Honda GX630 engine. I’ll be talking a lot about this engine in the review. Another great attraction is that this is the only Honda tri-fuel conversion that does not void your warranty.

Aftermarket conversion kits are available for some Honda generators, but these are retrofitted, hence it is considered a modification. No warranty agreement allows for modifications. Since the Winco HPS12000HE is a factory converted Honda engine, it is backed by a Winco warranty. This is not as great as the 3-year residential and commercial Honda warranty. Though, a 2-year residential warranty is quite satisfactory. It is still the same amazing Honda engine, so the shorter warranty should not really be a problem.

I have to start this review with my inexhaustible praise for the Honda GX630 engine. The entire Honda GX engine range is widely recognized as the best there is. Over the years, the feisty GX engine has come to represent the ultimate in durability, lightweight design, and fantastic fuel efficiency. The V-Twin GX630 is the top engine in this lineup. There really is no generator engine that can compare.

Even the original GX140 engine was remarkable for its time, featuring automatic valve decompression, overhead valve, and a super-efficient carburetor. These days, none of this seems that impressive. Back in the day, Honda was the first small engine manufacturer to include these great features. Naturally, the modern GX630 includes all of this and much more.

The pressurized lubrication, supplied by an oil pump, is fairly unique for this type of engine. Most use old-fashioned splash lubrication. This includes pressure-fed crankshaft bearings and insert-style rod bearings. This is more like the kind of stuff one expects to see on a high-performance racing engine, not a generator workhorse. It also has a sporty two barrel, inner-vent carburetor for improved power and excellent fuel efficiency. A rev-limiter prevents engine damage.

Honda engines are known for extremely hardcore durability, even in the harshest conditions. The GX630 engine takes this concept to new heights. The forged steel crankshaft and connecting rods, along with aluminum push rods with steel tips, are evidence of the superior engineering inside this engine. All this culminates in not just long engine life, but quieter, smoother, and more efficient performance. Reliability is greatly improved by the use of a digital CDI ignition system, which includes variable ignition timing.

If you know anything about engines, you’ll have to agree that the Honda GX630 is above and beyond anything used for similar applications, like generators, pumps, and pressure washers. Much of this technology is usually found only on racing engines. Even those who don’t have the same enthusiasm for engines, will appreciate the practical real-life implications of using the GX630 engine to power the Winco HPS12000HE tri-fuel generator. It’s an engine that will not let you down, last for years, and use very little fuel.

At full-power this frugal machine will run for an astounding 9.1 hours from the 15-gallon gas tank. Full power on the Winco HPS12000HE produces the watts to for an entire home, at least more than just basic equipment. It supplies 10,800W continuous output, with a surge capacity of 12,000W. No output data is supplied for propane or natural gas usage. You should expect this to be about 20% less when using natural gas, with propane somewhere between, probably around 10 – 15% less than the wattage output when running on gas.

An industrial engine is a good start, but the alternator has to be of an equal standard for us to rate this as a truly magnificent generator. This certainly rings true when we start unpacking the spec sheet for the alternator fitted to this generator. It comes pretty close to the best I’ve seen. Falling only a little short of the stupendous CAT RP range of generators. This would be what I consider the ultimate comparison for high-end, heavy-duty generators.

The brushless 2-pole, 120V/240V alternator on the Winco HPS12000HE is about as tough as they come. It also has one of the best voltage regulators you can get, second only to CAT and DeWalt industrial generators. Frequency is regulated to remain within the ±3% range, almost as good an inverter. Total harmonic distortion (THD) is also remarkable, less than 6%. CAT RP generators boast THD less than 5%, as do some DeWalt and Westinghouse models. This is as good as it gets when using a conventional portable generator. In fact ,this level of clean power is better than the grid power in most areas. When you consider that THD greater than 20% is quite normal for a standard portable generator, at <6% THD, the Winco HPS12000HE is a remarkable achievement. While not quite as low as inverters that produce THD less than 3% (some as low as <1%), the Winco HPS12000HE will not damage sensitive electronic equipment.

To make this the full package, when looking at robust design, the Winco HPS12000HE is mounted to a really solid frame with an optional 4-wheel dolly kit. If you ever intend moving this generator, I’d think the wheel kit is a must-have item, it weighs an incredible 272-pounds. I was quite impressed with the sound leve specification for this generator due, in part, to the amazingly smooth Honda GX630 engine. Okay, we can’t exactly say that 78dBA is quiet. Though if we are going to make a decent comparison, the Champion 100416 produces about the same noise level. Since the Winco generator is quite a bit more powerful, with a noticeably larger engine, the noise (relative to power output) is great for an open frame generator.

The industrial design of this generator is evident, once again, in the robust metal control panel. It has a full selection of outlets, which include a 12V battery charger. It has 2 X 120V, 20A household outlets (5-20R), a 120V/240V 30A outlet (L14-30R), and a 60A 120V/240V (L14-60R) outlet. I really like the 60A outlet, you don’t often find this on a portable generator. Since the Winco HP12000HE pushes out 45A continuously at 240V, with a peak surge capacity of 50A, the 60A outlet allows you to make full use of all this power. If the generator only had a 30A 120V/240V outlet, it would not be that convenient when using a single supply for a transfer switch.

Not only is the Winco HP12000HE an extremely well-made industrial generator, it is one of very few tri-fuel models available. These guys can be considered the masters of tri-fuel technology, they’ve been doing it since 1984. I can fully understand why the Champion 100416 is the more popular tri-fuel generator, it is much cheaper. Few are prepared to spend over four grand on a portable generator. Though, if you need a super-tough industrial grade generator with a high power output, this would be the only viable option in the tri-fuel generator market. I mentioned that the engine has a 2-year warranty, the rest of the generator is covered by a 3-year warranty. This is most certainly a solid, hardworking machine, and won’t let you down.

Tri-Fuel Generator Conversion Kits

You can buy conversion kits for most generator engines. The most important thing is to find a carburetor kit for the engine you’re using. Pressure regulators are fairly easy to find and are generally universal.

For a tri-fuel conversion, you need two pressure regulators for the natural gas and LPG supply. An on-demand regulator should be fitted directly to the carburetor converter. A standard low pressure regulator is connected to the propane tank. This is a common item, available at just about any department store with a hardware department. You may have to shop around a bit to find an on-demand regulator and carburetor converter.

I found the US Carburetion website when researching tri-fuel conversion kits for portable generators. They have a really great dropdown menu to select the make, model, and engine for just about every generator on the market.

I also found the Grenergy complete tri-fuel conversion kit for the ever-popular Honda EU2200i on Amazon. This kit will also work for the new, upgraded Honda EU2200iTAG, as it uses the same engine and carburetor as the original Honda generator.

I was really impressed with the quality of this kit. Although this is not an original Honda part, it appears to be up to the standard that I’d expect from the brand. There is no use retrofitting sub-standard parts to one of the best generators in the world.

All the components are made from the best materials and perfectly engineered. This kit is made specifically for the Honda EU2200i, making it really easy to install. There is no need to drill holes into your carburetor, as you probably would with a universal kit. It also contains all you need, including high-quality gaskets, bolts, even an NGK sparkplug, and all the fasteners. It really is an all-inclusive easy to use tri-fuel kit. Making it super easy to convert your existing EU2200i into a reliable Honda tri-fuel generator.

The problem with conversion kits is that they will void your warranty. You can read any warranty agreement (from any manufacturer) and you will always see that the warranty will not be valid if any alterations or repairs are conducted, unless by a certified dealership.

You could ask your local Honda service center if they are prepared to convert your generator to a tri-fuel setup. Though, to the best of my knowledge, this is not standard practice.
