6. DuroStar DS13000MXT 13,000-Watt 500cc Tri Fuel Portable Generator

   

   Best for Whole-Home Backup

   View on Amazon

   The DS13000MXT is aimed at buyers who put high output and fuel choice ahead of inverter refinement. Its listed 13,000 watts, tri-fuel operation, and transfer-switch-ready 50-amp outlet make it a fit for planning around multiple household circuits. A push-button start and fuel-selection knob simplify the control panel, while CO Alert adds an automatic shutdown feature if harmful fumes are detected. Compared with the Westinghouse iGen8200TFc, this DuroStar prioritizes a much larger stated wattage class rather than inverter features such as low THD and reduced noise. The tradeoff is that the supplied details do not specify running watts or runtime, making sustained-load planning harder. I’d skip it if quiet operation or clear fuel-specific output figures matter more than capacity.

   Pros:

   • Runs on gasoline, propane, or natural gas
   • 50-amp outlet is transfer-switch ready
   • Push-button electric start and front-panel fuel selection
   • CO Alert can shut down the generator when harmful fumes are detected

   Cons:

   • The supplied product details do not state running watts or runtime
   • No inverter or low-THD claim is provided, unlike the Westinghouse iGen8200TFc
   • Its high-output home-backup focus is less suited to buyers prioritizing quiet, fuel-saving operation

   Best for: Homeowners preparing to power several essential circuits through a transfer switch and wanting gasoline, propane, or natural gas flexibility.

   Not ideal for: Buyers who need documented running-watt figures, fuel-specific output, or inverter-style low-THD power for sensitive electronics.

   → See it on Amazon →

7. Westinghouse iGen8200TFc 8200 Peak Watt Tri-Fuel Portable Inverter Generator

   

   Best for Quiet, Clean Power

   View on Amazon

   The iGen8200TFc is the standout when inverter power quality and lower noise matter as much as backup capacity. Its less-than-3% THD rating is suited to electronics, and inverter control adjusts engine speed to demand; the listed noise level is about 60 dBA at 25% load. Unlike the larger DuroStar DS13000MXT, this Westinghouse trades peak output for those quieter, more fuel-conscious operating traits. Output also falls by fuel: gasoline provides 6,600 running watts, while natural gas provides 5,280, so buyers should size loads around their chosen fuel rather than the 8,200-watt peak figure. It includes a 50-amp outlet and RV connection, but anyone expecting substantial whole-home capacity on natural gas should look at higher-output open-frame options.

   Pros:

   • Less than 3% THD for sensitive electronics
   • Inverter speed control can reduce fuel use at lighter loads
   • About 60 dBA at 25% load
   • Includes 50-amp home-backup and TT-30R RV outlets

   Cons:

   • Running output is lower on propane and natural gas than on gasoline
   • Its 8,200-watt peak figure is not its sustained running output
   • Lower output ceiling than the 13,000-watt DuroStar DS13000MXT

   Best for: RV owners and households that want tri-fuel backup with inverter power for electronics and quieter operation at lighter loads.

   Not ideal for: Buyers who need more than 5,280 running watts on natural gas or prioritize maximum whole-home output over inverter benefits.

   • Peak output:8,200 watts on gasoline
   • Running output:6,600 W gasoline; 5,940 W propane; 5,280 W natural gas
   • Engine:298 cc, 4-stroke OHV
   • Fuel types:Gasoline, propane, natural gas
   • THD:Less than 3%
   • Fuel tank:3.9 gallons
   • Runtime:Up to 17 hours at 25% load
   • Noise:About 60 dBA at 25% load
   Our verdict

   “Pick the iGen8200TFc if cleaner, quieter inverter power matters more than the higher sustained capacity of an open-frame generator.”

   → See it on Amazon →

8. DuroMax XP13000HXT 13,000-Watt 500cc Tri Fuel Portable Generator

   

   Best for Heavy Loads

   View on Amazon

   The XP13000HXT makes the list for buyers who want a large running-watt reserve from a portable tri-fuel generator. Its listed 10,500 running watts give a more useful sustained-load reference than the DS13000MXT’s supplied details, which state 13,000 watts but omit running output. The 500cc engine, 8.3-gallon tank, and 50-amp transfer-switch-ready outlet point toward home backup rather than casual campsite use. Remote and push-button starting, plus a front-facing fuel interface, make fuel changes and startup less fiddly. The compromise is an eight-hour listed runtime and no inverter or THD specification, unlike the Westinghouse iGen8200TFc. I’d choose this DuroMax for demanding loads, not for someone who values long intervals between refueling or documented clean power for electronics.

   Pros:

   • 10,500 watts of listed running output
   • Runs on gasoline, propane, or natural gas
   • Remote and push-button electric start
   • 50-amp outlet supports transfer-switch connection

   Cons:

   • Listed runtime is eight hours
   • No THD or inverter specification is provided
   • Larger, higher-output design is more generator than many RV or light-use buyers need

   Best for: Homeowners who need substantial sustained output for several appliances or circuits and want the option to switch among three fuels.

   Not ideal for: Buyers seeking inverter-level power quality, long listed runtime, or a lighter-duty generator for occasional camping.

   • Starting wattage:13,000 watts
   • Running wattage:10,500 watts
   • Engine displacement:500 cc
   • Fuel types:Gasoline, propane, natural gas
   • Fuel tank:8.3 gallons
   • Runtime:8 hours
   • Outlets:7
   • Start:Push-button electric and remote start
   Our verdict

   “Choose the XP13000HXT for high sustained output and remote starting, but favor the Westinghouse iGen8200TFc for quieter inverter power.”

   → See it on Amazon →

9. Champion 8500-Watt Remote Start Tri Fuel Portable Inverter Generator

   

   Best for Ready-to-Connect Fuel Flexibility

   View on Amazon

   This Champion is a strong match for buyers who want tri-fuel inverter power with setup accessories included. The natural-gas and propane hoses come in the box, and its StartLINK connection can work with an Energy Storage System or Automatic Transfer Switch for automated start and stop. Clean output under 3% THD, a remote key fob with up to 80 feet of range, and a listed 64 dB(A) operating level suit home backup and RV use. Against the Westinghouse iGen8200TFc, Champion offers included fuel hoses and StartLINK, while the Westinghouse lists lower noise at 25% load. Champion’s 6,500 gasoline running watts also put it below the roundup’s larger open-frame options. Natural-gas output falls to 5,265 watts, so it is not an 8,000-running-watt choice on that fuel.

   Pros:

   • Less than 3% THD for electronics
   • Includes 25-foot natural-gas and 6.6-foot propane hoses
   • Wireless remote start works from up to 80 feet away
   • StartLINK supports connection to an ESS or ATS

   Cons:

   • Running output is 6,500 watts on gasoline and lower on propane and natural gas
   • Listed 64 dB(A) is louder than the Westinghouse iGen8200TFc’s level at 25% load
   • At 151 pounds, it is not a lightweight option to move by hand

   Best for: RV users and homeowners who value inverter output, included propane and natural-gas hoses, and compatibility with backup-system controls.

   Not ideal for: Buyers who need at least 8,000 running watts, especially on natural gas, or want the quietest listed operation.

   • Starting watts:8,500 watts
   • Running output:6,500 W gasoline; 5,850 W propane; 5,265 W natural gas
   • Fuel types:Gasoline, propane, natural gas
   • THD:Less than 3%
   • Runtime:Up to 13 hours at 25% load
   • Noise:64 dB(A)
   • Weight:151 pounds
   • Fuel hoses:25-foot natural-gas hose and 6.6-foot propane hose
   Our verdict

   “Choose the Champion for included fuel hoses and inverter features, but look to a higher-output model if your loads demand more than 6,500 running watts on gasoline.”

   → See it on Amazon →

10. FIRMAN T09275 Tri Fuel Portable Generator, 120/240 VAC Electric Start

    

    Best for Extended Worksite Runs

    View on Amazon

    The FIRMAN T09275 pairs 9,200 gasoline running watts with a listed 12-hour runtime, making it a practical choice for workdays or longer backup stretches between refills. It also gives buyers a fuel-specific picture: running output is 8,300 watts on propane but drops to 6,900 on natural gas. That distinction matters in a roundup centered on 8,000-watt generators, since this model clears that mark on gasoline and propane, not natural gas. Compared with the Champion 8500-Watt inverter, the FIRMAN favors higher open-frame output over the Champion’s stated low-THD power and included fuel hoses. Electric start has recoil backup, and a CO sensor alert adds a safety measure. Its three outlets offer less connection variety than the Champion’s outlet set.

    Pros:

    • 9,200 running watts on gasoline and 8,300 on propane
    • Listed 12-hour runtime
    • Electric start plus recoil backup
    • CO Sensor Alert and low-oil shutoff

    Cons:

    • Natural-gas running output is 6,900 watts
    • Only three outlets are listed
    • No low-THD or inverter specification is provided, unlike the Champion inverter

    Best for: Contractors, farm operators, or households needing extended operation with higher output on gasoline or propane.

    Not ideal for: Natural-gas users who need more than 6,900 running watts, or electronics-focused buyers seeking a stated low-THD inverter generator.

    • Starting wattage:11,400 watts
    • Running output:9,200 W gasoline; 8,300 W propane; 6,900 W natural gas
    • Engine displacement:459 cc
    • Fuel types:Gasoline, propane, natural gas
    • Fuel tank:8 gallons
    • Runtime:12 hours
    • Outlets:3
    • Voltage:120/240 volts
    • Start:Electric start with recoil backup
    Our verdict

    “Pick the T09275 for longer worksite or backup runs on gasoline or propane, but not if natural gas must carry an 8,000-watt load.”

    → See it on Amazon →

11. Generac 12,500 Watt Tri Fuel Generator with EFI and Electric Start

    

    Best for EFI and High-Output Fuel Flexibility

    View on Amazon

    I’d choose this Generac when the priority is substantial backup capacity across several fuel sources, not a generator that stays close to the 8,000-watt class. It supplies 9,500 running watts on gasoline, with 8,550 on propane and 7,000 on natural gas, so it has more headroom than the Champion 8125-Watt Electric Start Tri Fuel Portable Generator, especially when gasoline is available. EFI and a single-dial fuel selector add convenience for owners who may switch fuels during an outage, while electric start saves effort and recoil start provides a fallback. The tradeoff is its 219–227-pound weight: wheels help with movement, but this is not an easy generator to lift or store. Its three-outlet panel is also less varied than setups with more receptacles. I’d skip it if portability or a quieter inverter design matters more than output.

    Pros:

    • High gasoline output of 9,500 running watts and 12,500 starting watts supports demanding backup loads.
    • Runs on gasoline, propane, or natural gas, with a fuel dial that allows switching without shutting down.
    • EFI is designed to improve fuel efficiency and reduce maintenance requirements.
    • Electric start, recoil backup, and a 50A outlet provide useful startup and home-connection options.

    Cons:

    • At 219–227 pounds, it is cumbersome to lift, transport, or store despite the wheel kit.
    • Natural-gas output falls to 7,000 running watts, limiting capacity compared with gasoline operation.
    • The three-outlet panel offers fewer connection points than some competing generator setups.

    Best for: Homeowners needing high-output backup for multiple appliances, with access to gasoline, propane, or a natural-gas line and a transfer-switch connection.

    Not ideal for: Buyers prioritizing a lighter, easy-to-lift generator, an inverter design, or a closer match to an 8,000-watt output target.

    • Gasoline running/starting watts:9,500 / 12,500 watts
    • Propane running watts:8,550 watts
    • Natural gas running watts:7,000 watts
    • Fuel types:Gasoline, liquid propane, natural gas
    • Engine:500cc OHV, 4-stroke, with EFI
    • Fuel tank capacity:7.5 gallons
    • Gasoline runtime:Up to 14 hours at 25% load; 10.5 hours at 50% load
    • Outlets:120V 20A GFCI duplex, 120/240V 30A L14-30R, 120/240V 50A NEMA 14-50R
    • Weight:219–227 pounds
    Our verdict

    “Choose this Generac for EFI, tri-fuel flexibility, and output above the 8,000-watt class, but skip it if low weight is a priority.”

    → See it on Amazon →

How We Picked

I compared these 11 generators by how well their listed output matches the 8,000-watt-class search, then weighed fuel flexibility, generator type, starting features, and practical backup fit. I gave closer attention to distinctions buyers can act on: inverter output and low THD for sensitive electronics, remote or electric start for easier operation, and CO sensors or alerts as useful safety features. Since the product details here do not provide comparable running-watt figures for all three fuels, I avoid treating peak wattage as the same thing as usable continuous output.

The order favors a strong balance of class fit and useful features, not simply the largest wattage number. That puts the Westinghouse 8200 inverter first, while the Champion 8500 and Champion 8125 serve buyers who want a close wattage match with different feature priorities. Larger choices such as the Westinghouse 14500, DuroStar DS13000MXT, and DuroMax XP13000HXT rank as better fits for higher-capacity needs, rather than automatic upgrades for every shopper.

Factors to Consider When Choosing Tri Fuel Portable Generators 8000 Watt

Wattage is only a starting point when comparing tri-fuel generators. I’d match your expected loads to the generator’s usable output on your chosen fuel, then weigh how you’ll start, connect, store, and maintain it. These broader checks help prevent paying for capacity you cannot use—or choosing a close wattage match that falls short on your actual setup.

Match Running Output to Your Actual Loads

Do not treat a peak-watt figure as the amount of power a generator can supply continuously. Start by listing the appliances or circuits you want to run, then check both their running demand and the extra power needed when motors start. Pay attention to the generator’s rated output on each fuel, since gas, propane, and natural gas may not provide identical capacity. A model with a higher headline number is not automatically the better choice if your essential loads fit comfortably within a smaller unit’s rated output. For an electrician-installed transfer setup, verify the generator’s output and connection details against the planned circuits before buying.

Choose Fuel Flexibility for Your Real Backup Plan

Tri-fuel capability is useful only when you can access and store the fuel you plan to use. Think through how you would obtain gas, keep propane cylinders ready, or connect a natural-gas supply during an outage. Check the specific model’s fuel-change procedure and output figures rather than assuming all three options perform the same way. A common mistake is choosing a generator for its flexibility without planning the right hoses, regulators, storage, or safe connection point. If one fuel is your primary choice, compare its rated output first and treat the other fuels as alternatives.

Decide Whether Inverter Output Matters More Than Frame Style

Inverter models in this lineup include the Westinghouse 8200 and Champion 8500, while the Champion 10,000 is an open-frame inverter option. Inverter technology and a low-THD specification can matter when you plan to power sensitive electronics, but check the manufacturer’s guidance for the devices you own. Do not assume every generator labeled inverter has the same output characteristics or operating behavior. Also weigh the physical setup: the generator may need to sit outdoors at a safe distance, while power cords or a transfer connection carry energy to the loads. Pick the generator type around what you need to power and how you will use it, rather than choosing by label alone.

Plan for Starting, Connections, and Safe Placement

Remote start can make a generator easier to operate from a distance, while electric start still means starting it at the unit. Check whether the controls, battery requirements, and supplied accessories fit your intended use; do not assume every start feature works in the same way. Transfer-switch-ready wording is not a substitute for checking compatibility with your home’s transfer equipment or having a qualified professional handle electrical connections. CO sensors or alerts add a layer of protection, but they do not make indoor or enclosed operation safe. Decide where the generator can run outdoors and how exhaust, weather protection, and cable routing will be handled before purchase.

Balance Extra Capacity Against Portability and Upkeep

Moving from an 8,000-watt-class unit to a 12,500- or 13,000-watt model can provide more capacity, but a larger generator may be harder to position and store. Check dimensions, weight, wheel and handle details, and the space required for safe operation; do not infer portability from the word portable. Maintenance planning matters too: review the manual for oil changes, fuel-system care, battery upkeep, and storage steps before a long outage makes them urgent. EFI, as listed on the Generac 12,500, gives that model a different fuel-management feature set, but it does not remove routine service needs. Pay for extra output or added features when they solve a specific need, not just because the biggest specification looks reassuring.

Frequently Asked Questions

Is an 8,000-watt-class generator enough to back up a home?

It can be enough for selected essentials, but the answer depends on the running and startup demands of the appliances and circuits you plan to power. List those loads and compare their combined needs with the generator’s rated output on your intended fuel. Central air conditioning, well pumps, and other motor-driven equipment can change the calculation because startup demand may exceed normal running demand. A transfer-switch plan also shapes which circuits you can use at once. If your load list exceeds the available output, a larger model such as the Westinghouse 12500 or DuroMax XP13000HXT may be a better fit.

Should I choose the Westinghouse 8200 inverter or a larger conventional-style tri-fuel generator?

Choose around your loads and output needs rather than assuming the larger generator is better. The Westinghouse 8200 is a close match to the target class and lists inverter output, low THD, and parallel capability. A higher-output option such as the Westinghouse 14500 or DuroStar DS13000MXT makes more sense when your planned loads call for added capacity. Confirm the rated output for the fuel you expect to use, since headline peak figures do not tell the whole story. For sensitive electronics, check the manufacturer’s output guidance for the specific devices you intend to connect.

Does tri-fuel operation mean I can switch fuels without preparation?

No. The generator must be set up for the selected fuel, and you need the appropriate supply, connections, and safe operating procedure for that fuel. Read the model’s manual for fuel-change steps and any required parts or adjustments before relying on a switch during an outage. Also compare the generator’s rated output across gas, propane, and natural gas so you know what capacity to expect. Plan fuel storage and access ahead of time, especially if natural-gas service or delivery access may be disrupted.

Is remote start worth choosing over electric start?

Remote start can be useful if you want to start the generator without walking to its controls, while electric start reduces reliance on a pull-start procedure but is operated at the unit. The Champion 8500 and Westinghouse 8200 list remote start, while several other options list electric start. Check what the remote feature requires, including any battery or range limits, and whether it suits the generator’s planned location. Neither feature replaces safe outdoor placement or a proper electrical connection. Choose based on how you expect to operate the unit, not just the convenience label.

When does it make sense to step up to a 12,500- or 13,000-watt model?

Step up when your load calculations show that a closer-to-8,000-watt option cannot run the circuits or appliances you need at the same time. The Westinghouse 12500, Generac 12,500, DuroStar DS13000MXT, and DuroMax XP13000HXT offer a higher-output class than the closest-match picks. That added capacity can be useful for larger backup plans, but it may bring more demanding storage, positioning, and fuel needs. Compare the rated output on your preferred fuel, not just the model’s peak figure. If your essential loads fit a smaller generator, the larger unit may add bulk without solving a real problem.

Conclusion

For the best overall balance in this roundup, I’d choose the Westinghouse 8200 inverter, whose low-THD output, parallel capability, and CO sensor make it a feature-rich close match to the target class. For best value as a wattage-class fit, the Champion 8125 electric start keeps the focus on tri-fuel operation and output near the requested range. Buyers seeking a premium feature distinction should look at the Generac 12,500 with EFI, while beginners who prioritize remote starting and inverter design may prefer the Champion 8500 remote-start inverter. For higher-capacity needs, compare the Westinghouse 14500, DuroStar DS13000MXT, and DuroMax XP13000HXT against your load plan; the DuroMax XP9500iHT, Champion 10,000 open-frame inverter, Westinghouse 12500, and FIRMAN T09275 each offer alternate feature and output combinations. My final check would be the rated output on your chosen fuel, followed by connection compatibility and a safe outdoor operating plan.
