At a Glance

I have found out that most of the Champion Power Equipment inverter generators pack a punch in terms of reliability and functionality. 

The 4000-Watt duel-fuel inverter generator (Model 100574) wasn’t any different. It signified the performance and excellence at first glance, a motto Champion Power Equipment projects and lives for. 

The most significant features of this duel-fuel digital inverter include:

  • Noise reduction with the help of Quiet Technology.
  • Smaller and lighter mechanical design to help increase portability and mobility.
  • Extended run times of up to 16-18 hours.
  • Clean power output with minimal Total Harmonic Distortion.
  • Cold start technology to help start the unit quickly in colder climates.
  • Option to increase the power output by connecting more of the same units in parallel with the help of an optional parallel kit (not available with the unit, to be sold separately).

About Champion Power Equipment

Given their reputation and status and from what I learned about them, Champion Power Equipment is quite reliable in power generation equipment manufacturing. The company has been a market leader and provider of durable power products worldwide since its inception in 2003. Champion grew from a $40 mil to a $120 mil company in just a decade, which is, in fact, quite an achievement.

Due to the high-quality products, state-of-art innovations, a world-class R&D facility, and reliability of the power generation equipment, Champion quickly became a reputable brand worldwide. 

Another reason for their booming success is probably their flawless and more-than-satisfactory customer service by their certified technicians to assure that every customer is a happy and satisfied customer.  

Champion’s Product Categories

Initially based in Cali, Champion’s reputation gained traction for designing and manufacturing machinery and supply equipment like wood chippers, pumps, etc., in its early years. With time, their product line started expanding to portable conventional and inverter generators ranging from 1.2kW to 12kW. They introduced their dual-fuel hybrid inverter generators in the market just a few years ago, which have been a huge hit ever since. 

They have sold more than two million portable generators in North America only over the last few years. The company has started to generate annual revenue between $10 and $100 million.

This shows how people have started to trust them. But that’s not my conclusion….just yet.

Champion Power Equipment – 100574 Dual Fuel Hybrid Inverter Features

Well, the Model 100574 is certainly not something too mainstream. It has a few special functions and features that make it rise in the ranks above the rest. 

Let’s go through them in an instant.

Control Panel – Ease of Access

The inverter unit allows quicker access to the controls with the help of the Quick Touch Panel. Every control/port has been labeled for easy understanding.

Duel Fuel Usage

Flawless operation on both propane and gasoline. No need to worry anymore if you face a shortage of one fuel type.

Parallel Ready Unit

This portable inverter generator is ready to be connected to another unit without any hassle to increase the output. A downside here is that you’ll have to purchase an optional parallel kit separately for that purpose.

Noise Reduction

Noise reduction of up to 50% compared to the conventional 3.5kW generators with the help of Quiet Technology.

Less Heavy and Bulky

An efficient and smaller mechanical design is 20% lighter in weight, thus increasing portability and mobility for camping and other outdoor uses.

Extended Run Time

An extended run time for up to 18 hours (on propane) at 3500 running watts.

Extremely Low THD

Clean power production for safe and secure usage. Total harmonic distortion or distortion factor in the output is always less than 3%, making the inverter’s power safe to use for sensitive electronic equipment.

Cold Start Technology 

It helps in ensuring that the generator starts quickly and efficiently in cold weather.

Output Ports 

This inverter generator has two 120V, 20A household outlets, and a 120V, 30A RV. It also has a 12V DC output with a dual USB adapter.

Engine Specs for Champion Generators

Let us talk about the engine specs of this generator unit now. Champion mostly uses two kinds of engines for most of its portable generator units, 196cc and 224cc. Both of them differ in HP and a few other features.

But I will focus on the engine used in the generator model 100574 and its salient features related to fuel type and efficiency.

What Engine Is Used in Champion – 100574 Inverter Generator?

The engine model being used in manufacturing the Champion Model – 100574 is the 224cc Champion OHV Engine, Model YF172IV-L_G. It has a max power output of around 5.1kW and a speed of 3600RPM. 

The main features of this EPA-certified engine are:

  • Single Cylinder
  • 4-Stroke
  • Air Cooled
  • Cast Iron Sleeve for increased durability
  • Recoil Start
  • Low Oil Shut-Off

You can find the engine’s manual here.

Fuel Type and Efficiency

This generator unit can run on two types of fuel, namely:

  • Propane (LPG)
  • Gasoline

This outstanding quality of the generator allows you to even switch fuels with just a quick turn of the fuel selection dial present on the Quick Touch panel. 

Fuel Tank Capacity

The gasoline capacity of the fuel tank of this generator is approximately 11 liters (or 2.9 gallons).

Why are these fuel types used for this generator unit?

These fuels aren’t chosen for this generator unit for no reason. They were most probably selected due to their specific advantages. I’ll tell you why.

Benefits of Using Propane

  1. Propane is a clean-burning fuel as compared to many other fossil fuels. That makes it better for the environment and your generator as well. 
  2. Your carburetor won’t require much cleaning during the residue-deposit cleaning processes. Hence, your engine won’t need any extra maintenance due to reduced carbon deposits. 
  3. Propane does not degrade over time, so you won’t need any expensive stabilizers to add to your propane tank to avoid the fuel from going bad.
  4. Propane can be used efficiently in extremely cold weather as well, giving it an edge over gasoline in areas with colder climates.

Benefits of Using Gasoline

  1. Gasoline produces more energy per unit of fuel than propane; hence it can be an ideal choice for running the generator in low fuel and high power requirements.
  2. Gasoline is considerably cheaper than propane if we compare the cost of per kW generation. That makes it more efficient in terms of economic values.
  3. Gasoline is easily available and extremely common. You won’t have to venture far to have your fuel tank filled. Propane may only be available at some specific locations in your vicinity.

How Long Will The Engine Run on Full Tank?

The run time of this inverter generator is different for each type of fuel. However, although the graph of load curve and fuel consumption is not linear, it is still somewhat close enough. So you should easily be able to estimate the running times, given your fuel capacity and load variations.

According to the industry standards for inverter generators with variable engine speeds, fuel consumption ratings are done at 25% load. 

So let’s get into the run times for the given specifications.

Propane (20 pounds)

At 3600 starting watts and 3150 running watts, the engine will keep running for a maximum period of 18 hours at a 25% load cap.

Gasoline (2.9 gallons)

The Champion engine will run for about 17 hours at 25% load while producing 4000 starting watts and 3500 running watts with a full gasoline tank.

Noise Levels

Whenever you visit a campsite or a park, you may find the atmosphere around it buzzing and humming with engine sounds. The fact is simple; portable generators are supposed to be loud. But guess what, the product I am reviewing today seems like an exception. 

Here’s how.

According to Champion, they have manufactured this inverter generator according to their advanced digital hybrid design. That allowed them to make it about 50% quieter than other traditional Champion generators. It incorporates ‘Quiet Technology’ in its design that has helped significantly in noise reduction. 

However, when comparing the noise levels of this generator with other similar models, I found out that several models are even quieter than this one while operating on full load. Hence, the advent of low noise portable generators is not so unusual and rare. 

Let’s get to know exactly how loud it is under different loads.

Full Load Noise Level

Under a load, Champion inverter model 100574 is among the quietest. Its maximum noise level is 64 dB under full load at a distance of 23 feet, which is just how a normal conversation would sound like. 

Variable Load Noise Level

Still not happy with the noise level? This generator unit comes with a pre-installed “Economic Mode” feature that helps reduce the noise levels even further by slowing down the engine according to the output power requirements.

So for variable loads, the noise levels may reduce even further to around 60 dB when the generator runs with ‘Economic Mode’ switched on. 

Noise Reduction Technology – Comparison with Other Models

Champion model 100574 is among the quietest portable generators out there, at 64 dB. But for the sake of authenticity of the claim made by Champion, let’s compare it with a few other similar generators.


  • Generac’s Guardian Line Series and Protector Gas Series have generators that produce sounds measuring 66 dB.
  • Kohler Power Systems have generators with noise levels of 69 dB. 


  • Westinghouse’s WH1000i produces an average sound of 59 dB.
  • WEN 56380i has a noise level of 57 dB.
  • Westinghouse iGen4500 fluctuates between 46 dB to 61 dB depending upon the load conditions.

Some of the portable generators made by Honda can produce noise as low as 50 dB.


Here we come to another crucial feature to review. The portability of the electric generators is of paramount importance if you like to move around for trips, camping, etc., and require a power source. 

Champion claims to have manufactured this generator unit using an efficient mechanical design that has helped in decreasing the overall weight by 20%.

Here’s what I found regarding the portability features and ease of mobility of Champion Model 100574.

Dry Weight

The dry weight of the generator unit is 82.2 lb / 37.29 kg.

Wet Weight

The wet weight, or curb weight of this generator is about 107.7 lb / 48.8 kg (that includes Engine Oil = 0.6 qt and full gasoline tank = 2.9 gals)


The model 100574 is pretty compact as compared to others in the same line. It can easily fit your vehicle without taking up much space due to its smaller-than-average size. Its dimensions are:

  • Length: 20.5 in / 52.07 cm
  • Width: 18.3 in / 46.48 cm
  • Height: 18.9 in / 48 cm


A few downsides here about this generator model are that it does not come with a wheel kit, and there are no carrying handles

As the wet weight of the kit is around 107.7 lb / 48.8 kg, and there are no handles to carry it, Champion recommends that two people simultaneously lift the generator unit by its frame and move it to the desired location.

However, a similar Champion model has the same specs and all, the 100574-1 Dual Fuel Inverter. The model 100574-1 comes equipped with a wheel kit and a folding handle. So if you move your generator unit around on the ground a lot, you should opt for that model.

On the flip side, the weight of the model 100574-1 increases by 5 pounds (to 88.0 lb) due to the addition of the wheel kit.

If you want to buy a separate wheel kit and add it to your generator unit, you can visit this official link.

Portability Comparison with Other Models

While relating the Champion 100574 Dual Fuel Inverter with other models, it was observed that this model unit’s dimensions are smaller compared to the average portable generators with the same specs in the market. 

However, this model falls short of being the best if we compare it with others based on the overall dry weight. 

Here’s how a few similar models fare in dimensions and weight in comparison.


  1. Westinghouse iGen4500 Super Quiet Portable Inverter Generator
  • Dimensions: 24.5 x 17.5 x 20 inches
  • Weight: 93 lb
  1. Pulsar 4,000W Portable Gas-Powered Quiet Inverter Generator
  • Dimensions: 24 x 18 x 21 inches
  • Weight: 92.6 lb


  1. Westinghouse iGen4200 Hybrid Open Frame Inverter Generator
  • Dimensions: 24 x 20.5 x 20 inches
  • Weight: 80 lb
  1. WEN GN400i RV-Ready 4000-Watt Open Frame Inverter Generator
  • Dimensions: 19.8 x 13.8 x 18.9 inches
  • Weight: 66.1 lb

Champion offers a 3-year limited warranty for this generator equipment and a lifetime free tech support if you ever encounter any issues. For this, you will have to register your product through their official link.

This warranty period is quite reasonable and on-par with what other brands offer for similar models, so there is no downside here.

Commonly Known Issues

Any electrical product rarely comes out to remain flawless during its use for extended periods. The same is the case with this inverter. 

I came to know about a couple of issues that are faced by its users commonly.

Cut Off Propane Supply To Turn the Unit Off

The generator unit won’t just turn off using the switch if you run it on propane as you can do on gasoline. The engine will keep running if the propane supply is still being supplied, so you will have to cut off the fuel supply to turn the unit off every time after use.

Shaky Vibrations

After a few thousand hours of use, the generator unit becomes a bit shaky. It could damage the frame in the long run if the generator is placed on hard ground for a long time.

Frequently Asked Questions

Here are some of the common questions asked by the customers who have bought or intend to buy this generator unit.

What makes this generator a hybrid generator, and what are its features?

This inverter generator has been built by incorporating almost all the features of an enclosed inverter generator on an open frame, just like a conventional generator. That has allowed Champion to use a bigger engine and add more power to it at the expense of noise cancellation enclosure. 
Hence, the low cost and all other features mentioned in the review above make this product exceptional.

Does model 100574 include a wheel kit?

The model 100574 does not include a wheel kit. However, you can purchase it separately and install it yourself. If you want to save yourself from that hassle, go for the other similar Champion Hybrid Inverter Generator models with wheel kits like the one I had mentioned in the above review.

Can this generator be fixed in any enclosed compartment at home or in an RV?

Champion never recommends using the air-cooled, portable generators in any enclosed spaces without adequate ventilation. I would also personally suggest that you use it in an open atmosphere, away from the doors and windows of your home, to avoid any carbon monoxide buildups.

Does Champion provide any conversion kit so that I can run this generator on natural gas?

The 100574 inverter generator is not designed to run on natural gas and only runs on gasoline and LPG.
Additionally, Champion does not provide any such conversion kits. Any such third-party installations may void your warranty and cause safety issues, so be careful and get technical assistance beforehand if you plan on installing a conversion kit at your own risk. Champion does not claim any responsibility for third-party modifications.

What is the fuel consumption rate at specific loads for the #100574 inverter generator unit?

The generator will run for 18 hours at a 25% load cap on 20-lb propane. I have also mentioned the fuel consumption of gasoline in the review above.

Will this generator be able to run the 15,000BTU AC?

The RV’s 15,000BTU AC typically requires about 3.5 kW to turn on. So this generator should be able to power it quite easily.

What type of engine oil should I use for this generator?

Champion recommends that you use 10W-30 for your engine.

I have heard that other inverter units are even quieter? What makes it better at 64 dB?

Ans: Other inverter generators, such as Honda EU 2200i, may be quieter because they are pretty high-end. But the main differences are that the other inverter generators, though a lot quieter and noiseless than the Champion 100574, do not produce this much power and have almost double or triple the prices. 
I have also mentioned a few features and specs of this generator in the review above that make it stand out from the rest. Go through them, and you will know why this generator is a great value for money.

Does this generator come with a waterproof cover?

No covers are included with the unit. You will have to buy them separately.

What is the Total Harmonic Distortion of the output power?

The maximum THD that is observed in the output of this inverter unit is 3%.

What is the total weight of this generator unit? Can I move it around alone?

The dry weight of the generator is 82.2 lb. I have mentioned its wet weight in the above review as well. I would recommend that you get some help and try not to lift and move it around alone.
