Westinghouse 14500 Peak Watt Tri-Fuel Generator
The Westinghouse 14500 is a high-output tri-fuel model designed for larger homes or job sites. It provides 14,500 peak watts on gasoline and around 12,000 peak watts on natural gas, with corresponding running watts suitable for essential appliances. Best for buyers who need robust backup power and long run times on a spacious tank. Consider the 9.5-gallon tank for extended operation, or switch to propane for quieter, cleaner runs. A potential limitation is the larger size and weight, which affects portability.
Westinghouse 12500 Peak Watt Tri-Fuel Generator
The Westinghouse 12500 offers three-fuel flexibility with 12,500 peak watts and 9,500 running watts on gasoline. It features remote start, a digital hour meter, and two GFCI outlets plus transfer switch capabilities. This model is well suited for mid-to-large homes and those who want a balance of power and ease of use. A caution is that some users may prefer higher peak output for whole-home loads during heavy outages.
DuroMax XP13000HXT Tri Fuel Generator
The DuroMax XP13000HXT delivers 13,000 watts and supports gasoline, propane, or natural gas with a robust 500cc engine. It includes CO Alert for safety and emphasizes fuel flexibility for storms. This model is ideal for buyers who want a strong tri-fuel option with CO protection and a straightforward fuel selector. A limitation to note is that high output can lead to greater fuel consumption if run at full load for long periods.
Westinghouse 13500 Peak Watt Tri-Fuel Generator
This model provides 13,500 peak watts with 10,500 running watts on gasoline, plus substantial propane and natural gas outputs. Remote start and a 19-hour runtime on a large 9.5-gallon tank support lengthy outages. Best for users needing strong power plus long run times. A potential caveat is the higher price point relative to smaller tri-fuel units.
Generac 12,500 Starting Watt Tri-Fuel Generator
The Generac model provides 12,500 starting watts and 9,500 running watts with tri-fuel capability and COsense detection. It features an electric start and a 7.5-gallon fuel tank with up to 9.5 hours runtime at 50% load on gasoline. This choice suits buyers seeking automatic-start convenience and integrated CO protection. Limitations include a more complex setup for those not using the remote start feature regularly.
DuroStar DS13000MXT Tri Fuel Generator
The DS13000MXT from DuroStar emphasizes full-home power with 13,000 watts and tri-fuel capability, plus a CO Alert. It offers a push-button start and a broad array of outlets, including a transfer switch-ready 50-amp outlet. It’s well suited for homeowners who want a straightforward, wired-ready unit. A limitation is that the design leans toward heavier, less portable use rather than light-duty transfer setups.
Westinghouse 8200 Peak Watt Tri-Fuel Inverter
The Westinghouse iGen8200TFc combines inverter efficiency with tri-fuel flexibility, offering 8,200 peak watts on gasoline and lower outputs on propane or natural gas. It includes a 50A transfer switch-ready outlet and a CO sensor. This model is best for buyers prioritizing clean, stable power for sensitive electronics and quieter operation. A limitation is that peak output is lower than full-size open-frame models, so plan loads accordingly.
WEN TF-1450X 14,500-Watt Tri-Fuel Generator
The WEN TF-1450X offers 14,500 surge watts and 11,500 running watts on gasoline, with propane and natural gas options. It supports 120V/240V operation and a transfer-switch-ready setup. The CO Watchdog feature helps protect households from carbon monoxide. This model is a solid choice for users seeking a balance of high power and transfer-switch readiness, though setup can be more involved for first-time buyers.
Buying Guide
Fuel flexibility: Tri-Fuel models provide versatility during fuel shortages or fuel price spikes. Prioritize a unit with a simple fuel selector and clear indicators for each mode.
Power needs: Compare peak watts and running watts to determine if the generator can handle your essential loads (air conditioner, fridge, sump pump, lights). For whole-home backup, aim for higher peak and sustained wattage.
Transfer switch readiness: If you plan to connect to a home panel, confirm the unit includes or supports a transfer switch kit and compatible receptacles. Outlets and safety interlocks matter for reliable operation.
Runtime and tank size: Larger tanks extend runtime but add weight. If you need long outages, calculate gallons per hour at a typical load to estimate runtime.
Safety features: CO detectors, automatic shutdown on low oil, and proper grounding improve safety in emergencies. Look for inverter models if you have sensitive electronics and prefer lower noise and better fuel efficiency.
Portability vs. capacity: Open-frame generators offer more power but are heavier and louder. Inverter-based tri-fuel units are quieter and better for limited spaces, though some models peak at lower wattage.
