The Champion 8500-Watt Dual Fuel Inverter Generator is purpose-built for homeowners and outdoor enthusiasts who need dependable backup power without the noise and hassle of traditional generators. Whether you're weathering a multi-day power outage, powering an RV setup, or running equipment at a remote job site, this unit delivers the quiet operation and fuel flexibility that serious users demand.
What truly sets this generator apart is its combination of ultra-quiet 61dB operation with impressive 8500 starting watts and substantial runtime. The dual fuel capability means you can operate on gasoline for up to 14 hours or propane for up to 12 hours at 25% load, and switching between fuels is as simple as turning the EZ Start Dial. The electric start with included battery eliminates the frustration of pull-cord starting, while Economy Mode intelligently adjusts engine speed to reduce noise, fuel consumption, and wear as your power demand changes.
Build quality is exceptional throughout. The 420cc Champion engine, no-tool access panel, and oil drain tube make maintenance straightforward. The Intelligauge display monitors voltage, frequency, and operating hours in real time, while multiple outlet types (240V 29.2A, 120V 20A GFCI, and 12V) provide clean power for sensitive electronics with less than 3% THD.

Buying Guide: What to Look For
Power Output and Fuel Type
The wattage rating determines what you can run. Starting watts are needed for motor-driven appliances like refrigerators, while running watts are for continuous operation. A dual-fuel capability, like that found on the Champion 8500-Watt Electric Start Dual Fuel, provides critical flexibility. You can choose between gasoline for maximum power or propane for cleaner, longer-shelf-life fuel storage, a major advantage for emergency preparedness.
Starting Mechanism and Portability
An electric start with a battery included is a game-changer for convenience. It eliminates the struggle of a recoil cord, which is especially valuable in cold weather or if the unit needs to be started frequently. Consider the unit’s weight and whether it has wheel kits and handles. A portable generator should be relatively easy to move to your desired location, whether in your driveway or at a campsite. For more on portable options, see our dedicated review of the best Briggs & Stratton portable generators for 2026.
Noise Level and Outlet Configuration
Noise is measured in decibels (dBA). A quieter generator, often an inverter model, is essential for camping, neighborhoods, and RV parks to avoid disturbing others. Check the outlet types on the generator to ensure compatibility with your needs. You’ll want a mix of standard household outlets, possibly a 240V outlet for larger appliances, and a 12V DC outlet for charging batteries. Inverter technology, which provides clean, stable power for sensitive electronics, is a key feature in modern units like the best Briggs & Stratton inverter generators.
Safety Features and Runtime
Modern safety is non-negotiable. Look for a carbon monoxide (CO) auto-shutoff system that automatically turns the generator off if dangerous levels are detected in an enclosed space. GFCI-protected outlets are vital for outdoor use to prevent electrical shock. Finally, review the estimated runtime at a specified load. A longer runtime means less frequent refueling, which is crucial during extended power outages. For a broader look at reliable options, our guide on choosing the best Briggs & Stratton generators for reliable power offers further insights.

Frequently Asked Questions
What can an 8500-watt Briggs & Stratton generator power?
An 8500-watt generator can typically handle a central air conditioning unit, a well pump, a refrigerator, lights, and several smaller appliances simultaneously. It is sufficient for most whole-house backup needs, though you should always calculate your specific home’s wattage requirements to be sure. The dual-fuel capability also allows you to switch to propane, which can be easier to store for emergencies.
How important is an electric start on a portable generator?
Electric start is highly valuable for convenience and accessibility. It allows you to start the generator with the simple turn of a key or press of a button, eliminating the physical effort of a pull cord. This is particularly beneficial in cold weather when engines are harder to start, or for users who may have difficulty with the pulling motion.
Are inverter generators better than conventional ones?
Inverter generators are generally superior for powering sensitive electronics like laptops, smartphones, and medical equipment because they produce clean, stable electricity with low total harmonic distortion (THD). They are also much quieter and more fuel-efficient than conventional open-frame generators, making them ideal for camping, tailgating, and residential use where noise is a concern.
What maintenance does a Briggs & Stratton generator require?
Regular maintenance is crucial for reliability and longevity. This includes checking and changing the oil regularly, using a fuel stabilizer or running the engine dry for long-term storage, inspecting the air filter, and keeping the unit clean and dry. Always consult the owner’s manual for the specific maintenance schedule and procedures for your model to ensure it’s ready when you need it most.
