Champion 7500-Watt Dual Fuel Portable Generator Review

by Charles Jasper

Product Overview

If you’re looking for maximum power in a portable generator, with the added benefit of dual fuel versatility, look no further than the Champion 7500-Watt Dual Fuel Portable Generator. This 439cc engine provides plenty of power, whether it’s running on gasoline or liquid propane. It’s loaded with features, including Champion’s signature Intelligauge, Volt Guard, and Cold Start Technology.

Other features include a propane hose, so you don’t have to worry about connecting your propane cylinder, a 6 gallon (22.9 L) gas tank, a push-button electric start, and a safety fuel selector switch. Getting the power you need to meet your goals has never been more convenient. The electric start comes with an included battery, and you’ll never have a problem starting it in cold weather.

Intelligauge makes it easy to keep an eye on your power output, thanks to readings which track voltage, hertz, and runtime. The generator uses easily available 10W-30 oil (with some included to start you off) and has a low oil automatic shut off. You’ll be able to start it up right out of the box with either gasoline or propane. Switching between fuel is easy; the generator has a built in patented safe fuel selector switch.

Champion 7500-Watt Dual Fuel Portable Generator

Champion 7500-Watt Dual Fuel Portable Generator
  • 9375 starting watts (gas)
  • 7500 running watts (gas)
  • Low Oil Shut-Off
  • Electric and Recoil Start
  • 3-year limited warranty

And while this isn’t the lightest or smallest portable generator on the market, no one can deny that it’s powerful. When fueled by gasoline, it starts out at 9375 watts and runs at 7500 watts; its 6 gallon fuel tank can power the generator at 50 percent load for eight full hours. When using a 20 pound propane tank, it starts out at 8400 watts and runs at 6750 watts, and will power a 50 percent load for 5.5 hours.

The 3.3 foot propane hose has a built in regulator, so this generator is truly ready to go as soon as you unbox it. You might expect a generator this powerful to be excessively loud, but at 75 dB, it’s only a little louder than a standard vacuum.

With all of this powerful convenience at your disposal, you’ll be well covered in the event of a power outage, and your devices and equipment will be protected by Champion’s exceptional Volt Guard to prevent surges.

And speaking of powering your equipment, you’ll find no shortage of outlets and types, rendering adapters unnecessary in most cases. It has a 120V 30A locking outlet (L5-30R), four protected household outlets (120V 20A GFCI protected, 5-20R), and a 120/240V 30A L14-30R locking outlet.

Not only is it easy to set up and get running, it’s simple to store and its never-flat tires mean you won’t have to worry about how to move it into position when you needed. It’s EPA certified, and comes with a lifetime of free technical support from Champion’s renowned Champion Support service.

Is This the Right Generator for You?

A generator, regardless of your needs, is a serious investment. Is this unit the right one for you? Here are a few of the points you should consider when making a decision.

Fuel Sources

Obviously, one of the main selling points of a dual fuel generator is the fact that you can two fuel options. Why is this such an advantage? There are a few reasons, including the availability of fuel and fluctuations in prices. While both propane and gas are usually easily available, emergency shortages can easily make one or the other more difficult to get. Fuel prices can also fluctuate wildly—especially during an emergency.

Size and Power

Size and power are always going to be relative to one another when it comes to generators. This unit is very, very powerful for its 200 pound size, but it is on the upper end of weight for a portable generator. If you need this level of power, it’s a great choice. If your power needs are somewhat lower, however, you might want to opt for a smaller, lighter unit.


Whether we’d like it to be or not, budget is almost always a consideration when making a sizeable purchase of this nature. Bear in mind that dual fuel generators may have a somewhat higher initial cost, but can save you money in the long run due to being able to switch fuel sources depending on current prices.

In the end, whether or not this is the right generator for your needs will depend upon just that—your needs.


  • Never worry about fuel availability with the versatility of the best dual fuel generator in its class
  • Exceptionally powerful for a portable generator; higher starting and running watts than other generators of its size
  • Ease of use—a simple push button start, well-labeled features, and a safe fuel selector switch


  • Necessity of keeping charged batteries on hand in the event of a power outage—the push button start relies on battery power
  • Heavier than other portable generators, at slightly over 200 pounds
  • More moving parts and higher complexity than a single fuel source generator, meaning a greater likelihood of breakdown


Champion has outdone itself with this unit. They’ve maximized power and ease of use in a generator that can still be classified as portable—especially considering its exceptionally engineered wheelbase. You’ll have the convenience of cheap, readily available gasoline, but also the reassurance of being able to use easily stored, clean burning propane at your discretion.

Overall, this Champion 7500-Watt Dual Fuel Portable Generator is outstanding in its class, and Champion’s legendary customer service and technical support is just the icing on the cake.
