Champion 4000-Watt Generator Reviews

The Brand

Champion generators are supplied by Champion Power Equipment. They’re a market leader in, surprise, equipment for the generation of power.

They’ve been around for years and their products have a reputation for dependability, having operated in the North American market since 2003. 

They were started in Santa Fe Springs, California, and they have expanded into Jackson, Tennessee, and Milwaukee, Wisconsin, as well as Toronto, Canada. Between these locations, they have much of the United States covered.

They’ve shifted around two and a half million generators across the States and, if you’re an international reader, there’s every chance you’ve seen a Champion generator since they’re also active in the world market.

So, what does Champion Power Equipment offer? You’re after generators, so we already know they have a great collection of portable, semi-portable, and domestic standby generators to have your power solutions covered.

They also supply inverter generations as well as engines, winches, and log splitting equipment.

The Generators

Let’s focus on those generators since that’s what you’re after. Champion has always tried to stay one step ahead in terms of the technology that goes into their generators.

It’s a competitive market, so they need to have the best gadgetry and be transparent about what goes into their generators if they want to get ahead of their competition.

An example of these innovations is the Dual Fuel tech that makes their generators efficient to run, getting you more power from less fuel where portable generators are concerned.

Another example would be V-Twin engines that are found in some of their other products too, providing more power than generators that don’t have this type of engine.

Another great feature that puts the portable in portable generators is wireless remote functionality. From up to eighty feet away, you can start or stop your generator thanks to a convenient remote.

They’re also pretty safe to run, featuring Champion’s own CO Shield where the products they supply will auto-shut off when carbon monoxide is detected.

Carbon monoxide is a silent killer, so it’s important that any gadgets with the capacity to produce carbon monoxide have taken these safety precautions.

The best way to show you Champion generators is to, well, show you Champion generators. That’s what we’ve done below, you’ll find a few generators along with a small review of each.

We’ve focused on RV-compatible 4000-watt models, but we’ve also added in a more powerful generator so you can see what one of the higher-end Champion generators are capable of.

Champion 4000-Watt Generator Reviews


Champion Power Equipment 100302 4000-Watt RV Ready Open Frame Inverter, Yellow

Here’s one of the higher-end generators that Champion offers that has a starting wattage of 4000, which falls to about 3500 during practical use.

The reason this 4000-watt generator by Champion Power Equipment is more expensive than some of the other 4000-watt generators they have is that it’s an open frame inverter.

This means it’s designed to weigh less, about one fifth less than other Champion generators of the same wattage. It’s also half as quieter, though this doesn’t eliminate noise entirely.

It also features an Economy Mode, which is handy for when you need the generator to run for longer than usual and want to make your fuel go further.

The average runtime has been extended over previous Champion models too, running up to seventeen hours when working correctly.

The generator is also Parallel Ready, so the use of a Parallel Kit can have you connect up to two digital hybrid generators or inverters as long as they’re over 2800 watts.

The generator comes with an oil funnel for refueling, battery charging cables to get the power out, and a USB adapter to expand how many devices you can move power into.

In fact, Champion tries to make their generators friendly with electronics that are sensitive and require clean electricity.

Their RV Ready range of generators have a 120V 30A RV outlet, obviously, as well as 120V 20A household outlets and a 12V DC outlet that’s accompanied by that dual USB adapter.

As with all Champion products, they have a support line stacked with experts you can call should you have any issues.

There’s also a three-year limited warranty that’ll fortify your purchase against damages that aren’t your fault.


  • This generator’s open frame inverter design makes it 50% quieter and 20% lighter than Champion’s older generator offerings.
  • Features an extended running time and Quiet Technology that makes it efficient and unobtrusive to run.

This generator is Parallel Ready, meaning that you can connect other generators to it using a Parallel Kit.


  • Quiet Technology is relative to other generators, it still makes noise.


Champion Power Equipment 100307 4375/3500-Watt Dual Fuel RV Ready Portable Generator

Here’s a cheaper 4000-watt generator than the first one we’ve covered, plus it’s more portable too.

This generator weighs approximately 104.9 pounds and it comes with a 3.3-feet long single LPG hose and accompanying regulator. 

As for some other specs, it also has a fuel tank capacity of 3.4 gallons and will produce 68 A-weighted decibels when its 224cc engine is running.

You can run the generator with either gasoline or propane, and no matter which one you use, the generator will turn off automatically if the fuel inside falls below 0.6 quartz.

The star of the show with this generator is its Intelligauge functionality. The Intelligauge measures a variety of different metrics associated with your generators such as voltage, hertz, or run-time hours.

Between these, you can monitor your power output and optimize your generator to be as efficient as possible.

You can even use Intelligauge to track maintenance intervals for the generator, allowing you to determine how much manual intervention is required to run the device.

As for outlets, it has the expected 120V 30A RV outlet as well as a 120V 30A locking outlet and a pair of 120V 20A household outlets to distribute power through domestic areas.


  • A portable 4000-watt generator that weighs 104.9 pounds and comes with an LPG hose and regulator.
  • Operates right out of the box using either gasoline or propane, whichever you prefer. The generator will auto-shut off when the oil falls below 0.6 quarts.
  • Intelligauge allows you to keep track of voltage, hertz, and run-time hours.


  • No quieting tech, so it’s pretty loud.


Champion Power Equipment 100165 9375/7500-Watt Dual Fuel Portable Generator with Electric Start

This Champion generator is substantially more powerful than a 4000-watt generator, having a starting wattage of 9375 and a consistent running wattage of 7500.

It’s bigger and better in most respects, including the beefier 439cc engine that’s contained within the generator. It also has a toggle switch for easy operation.

It has Dual Fuel capability, meaning it can produce power using either gasoline or propane, and it’ll shut off automatically if fuel reserves get too low.

Another safety feature it has is Volt Guard, a surge protection system that stops overloads and drastically reduces the chances of failure.

This model also features the Intelligauge, which should be expected since this is a higher-end portable generator than the 4000-watt portable we covered above.

This system tracks voltage, hertz, and maintenance intervals so that you can make sure you get the most out of your generator, which is more worth doing with powerful generators like this.

If you hadn’t caught on by now, Champion is still offering those three-year limited warranties with purchases like this, protecting you from poor workmanship and other problems that aren’t your responsibility.

There’s also free lifetime technical support for if you have other problems that need talking through.

Being our example of what a high-end portable RV generator from Champion looks like, it’s also the most expensive product on this page.


  • A very powerful portable generator that has Dual Fuel capability and an equally powerful 439cc Champion engine with a toggle switch.
  • Also features the Intelligauge monitoring system that enables you to optimize your generator usage.
  • Volt Guard built-in surge protector prevents overloading and other electrical failures.


  • One of the most expensive generators that Champion offers.
