There are different power backup options and having a generator leads the pack. In particular, a generator is reliable with a sustainable power capacity, especially in areas marred with unreliable grid supplies or completely off the grid. As such, you can use a generator during power outages, emergencies or even when a storm hits your area. Alternatively, you can choose to throw a generator-fired party in your backyard, supposing you don't have any electrical connections outside.

Moving forward, it is still important to choose the right generator models for optimal reliability, efficiency and sustainability. The point is, there are better alternatives to gasoline-only traditional generators, and our current context will cover the dual-powered inverter generators. The duality in this alternative already spells further back up with the option of extra fuel in your generator.

Among the best dual-powered inverter generators, we have taken interest in the Champion dual fuel inverter generator. Specifically, Champion Power Equipment has, over time, gained popularity due to its innovation in powering life through cost-effective and clean energy. As such, Champion Power Equipment is trustworthy in providing that much sort after backup power. However, before we review our select generator, let's first understand the concept of a dual fuel power backup.

What is a Dual Fuel Generator?

Unlike the gasoline-only traditional generators, dual fuel generators process electricity or energy from two fuel types. Notably, the mechanism of a dual fuel option utilizes both fuel options simultaneously, unlike the bi-fuel engines, which switch between fuel alternatives. In the dual fuel context, the combined fuels are gasoline and propane. Accordingly, generators in this category are much complex to maneuver, unlike their single-fuel counterparts.

Also, it is important to note that both of the fuel options are fed in different compartments in these generators. Then, it is left upon the mechanism of the individual dual generator to mix the two fuels as designed. Moreover, dual-fuel generators switch are created to switch modes between different fuel ratios, depending on the working conditions. Even more, this type of generator can run on one fuel type when the other one is unavailable or drained.

Alternatively, you can find dual fuel machines, with the second fuel being solar energy. This second model has reduced emissions but doesn't provide as much power as the gas-propane model. Furthermore, a dual-fuel machine should come with the convenience of portability for easy application where needed. Such a feature, among others, will be covered in our select product review.

Having understood the concept of dual-fuel in a generator, let's look at the practicality of this technology in the Champion dual-fuel inverter generator. Luckily, amidst this specific Champion power generator, you have watt dual fuel options: 4500-Watt Dual Fuel and 3400-Watt Dual Fuel.

Benefits of Dual Fuel Generators

1. Reliability

Primarily, inverter generators offer industry-leading reliability through two usable fuel options. Most of the time, gasoline is a handy go-to option for running machines. Nonetheless, propane can be stored for long, making the dual-fuel option reliable. Also, when fuel is used in proportions, efficiency kicks in, making it reliable for long periods.

All-Season Reliability

Moreover, the reliability of these dual-fuel machines extends to all-season usability. Ideally, gasoline burns well when it is cold, while propane is ideal during hot seasons like in the summer. As such, you can switch the fuel in your dual-powered generator subject to the prevailing ambient temperature. Therefore, a generator with such adaptability is a reliable power backup option.

2. Budget-Friendly

In as much, these dual inverter generators can use both gasoline and propane together in proportions; you can still select one fuel type depending on availability and your budget or their prevailing prices. For instance, if your local gas stations have run out of gasoline, you can go through the night as you wait for a replenish or go looking in another station the following day. Also, whenever there are those ridiculous gasoline price hikes, you can still find refuge in propane fuel.

Subsequently, these dual machines can be considered cheaper with such budget flexibilities. Notably, propane is generally is cheaper than gasoline, but the latter is also easier to find than the former.

3. Worry-Free Emergencies

Inverter generators also feature flexibility even in the presence of hurricanes. Supposing natural disasters disrupt gasoline supply to your area, you can still shop for a propane cylinder anywhere- hardware stores, gas stations or even grocery stores. Following the purchase of your propane tank, you can easily plug it into your generator. Alternatively, you can use a quick solution by temporarily using your grill propane tank.

4. Extended Runtime

Furthermore, when using two fuel options, especially one after another, you may extend the runtime of your generator. This trick is particularly helpful in times of shortage, natural disaster or emergencies. Also, an extended runtime allows you to rush and get a refill of the depleted fuel. For instance, you can rush to your local gas station and get a gasoline refill as your generator runs on propane.

5. Eco-friendly

Having the option of two fuels also comes with the benefit of eco-friendliness. Burning natural gas comes with fewer emissions, unlike the traditional gasoline option. Even in the presence of propane-diesel/gasoline mixing, dual-powered machines render reduced carbon emissions.

What to Look for in the Best Dual-Fuel Generators

In this write-up, the main focus is on the Champion dual fuel inverter generator. We have also gone over the main features that make it stand out. While at this, it wouldn't break a bone identifying factors that guided us through the numerous options in the market.

1. Power Output

The first factor to consider is the power that a generator produces. Ideally, inverter generators come in different classes based on the amount of power they punch. Accordingly, different classes have different users depending on their respective power needs. As a result, knowing the power output of your generator will help you have a clear picture of how much power you will get during a blackout.

In line with matching your generator choice with your power needs, the consistency and quality of power of your dual-powered generator affect its utility performance. Simply put, the number of lights and appliances you need to power during a blackout will help you choose an adequate dual backup. In addition, understanding how powerful you need a dual generator to be, you will also be able to estimate running costs for each fuel.

A simple way of estimating running costs is making a list of appliances you will absolutely require all the time. Then add their wattage requirements to get a rough idea of the minimum power you will need from a dual-powered generator. Some of the common appliances to consider for generator support include a space heater during winter, refrigerators, lights, AC units during the hot season and maybe computers.

Watt Rating

More on power output, it is critical to consider that generator power is measured in watts. Precisely, dual-powered inverter generators come with specs of higher and lower power output. In some cases, manufacturers indicate further breakdown-peak outputs for individual fuels and respective running outputs. Peak putout refers to the max watts a generator can give at a single time while running power is a watt average during use.

Wondering why all these details? Indeed, these specs are important considering that gasoline produces a higher wattage than propane. Using the 3400-watt Champion dual fuel generator's ratings, gasoline is expected to give 3,400 watts while propane is expected to give 3,060 watts.

Therefore, this premise will help you not mistake your generator for misfunctions. Also, understanding watt ratings and specs can help you match your dual generator purchase to your estimated power needs.

2. Fuel Capacity

This factor, in practice, applies to the generator's gasoline tank capacity. Ideally, the large a generator's tank capacity, the better and longer a dual-powered generator can run. Not worry, fuel capacity bears nothing to do with propane holding capacity. The use of propane only requires connecting independent propane canisters to your generator when needed.

3. Recoil Cord vs. Electric Start

Another vital feature to check-in dual-powered inverter generators is the starting mechanism. There are two start mechanisms: recoil cord and electric start.

A recoil start mechanism is the typical traditional technology that is also common among conventional chainsaws, lawnmowers and generators. This start model requires quick and steady hands to kick-start a generator. Fortunately, you don't require electricity for this start mechanism. Also, you can conveniently start your long-stored generator without many complications.

On the other hand, you can opt for the electric start inverter generators. Fortunately, modern inverter generators come with internal batteries for storing electricity to help start your power back up by the simple flip or press of a switch or button. This alternative start method is easier than the recoil one. However, without a charged internal battery, it is impractical to have this backup for outages.

4. Other Start and Shutoff Features to Consider

As part of adding value to inverter generators, manufacturers are continually finding ways of making your machine last longer. Specifically, features under this consideration relate to powering on and off. Below are some added automated on/off features to look out for:

  • Auto CO turnoff: This feature is most common with portable inverter generators. This auto-shutoff happens upon the detection of dangerous gas build-up.
  • Autostart: Makes your work easier, right? Indeed, inverter generators with auto start save you the hassle of fumbling through darkness whenever lights go out. In addition, this feature helps keep your perishables fresh if you're not at home.
  • Low oil auto-shutoff: This feature mainly works when engine oil in your generation is below safe levels. Subsequently, this feature helps protect your investment in a generator by preventing damage that may be caused by low oil levels.

5. Operating Noise Output

Besides optimal power supplies, it is also important to consider the noise levels you will encounter as you enjoy power supply continuity. Industry-leading brands and models come with low noise outputs and still provide enough power. To know the noise levels of your select dual-powered generator, check for decibel (dB) measurements under the product specs.

On estimate, good inverter generators fall in the range of 50 to 90 decibels, which is similar to noise from a hairdryer and lower. Remember, your dual machine will run louder under gasoline than propane. Fortunately, the select inverter generators from Champion Power Equipment offer some of the quietest operations.

6. Portability

Size and Weight

The first aspect of inverter generators that relates to portability is size and weight. Machines like the Champion inverter generators are meant to be moved around in between working stations and stores. Consequently, size and weight ensure that your Champion Power generator fits in your vehicle's trunk for use anywhere desired.

Nonetheless, don't go for the smallest size to optimize portability. The smaller the generator, the lower the power output.

Wheel Kit

Also, the best inverter generators like the Champion Power dual-fuel inverter in this review come with wheels. Wheel kits help users move even the heaviest generator effortlessly. Let's say your dual-powered generator doesn't come with its wheels. You can still invest in a separate set of wheels to make portability possible or even replace worn-out generator wheels.

Lift/Pull Bar

Is it practical to have a generator with wheels but without a lifting bar? Certainly, portable generators should come with an ergonomic lift hook bar. Also, a lift hook bar is useful in moving portable generators in construction sites. Some may argue that this feature isn't necessary, but in truth, it's better to have it than require it and miss it.

Final Verdict

Having a Champion dual-fuel inverter generator in your garage is a brilliant idea for ensuring you never stay in the dark. Considerably, this generator brand and model is ahead of its counterparts in maximizing the application of gasoline and propane. In the long run, this Champion Power generator is sustainable, convenient, energy-efficient and friendly to the environment.
