Westinghouse 28000 Peak Watt Backup Portable Generator
Best for: Homeowners who need robust surge power and a wide outlet mix for whole-house backup. This model delivers 28,000 peak watts and 20,000 running watts, suitable for running several big appliances simultaneously. The remote start, electric push-button start, and a 17-gallon fuel tank with a fuel gauge support long runtimes, up to 15 hours at 25% load. It includes a full slate of outlets: four 120V household outlets, two 50A outlets, two 30A outlets, and more, making it versatile for transfer switches and heavy-duty power needs. The safety features include automatic low-oil and CO shutdown. Caution: with high peak wattage, this unit is heavier and may require more robust fueling and maintenance planning.
Westinghouse 18000 Peak Watt Home Backup Portable Generator
Best for: Families needing substantial power for longer outages without hitting the top-end surge. This model provides 18,000 peak watts and 14,500 running watts, with up to 16 hours of runtime on a 10.5-gallon tank. It features a durable V-Twin OHV engine, automatic low-oil shutdown, and a VFT data center so you can monitor output and maintenance. THD is under 5%, which is friendlier for sensitive electronics like TVs and computers. Caution: the 16-hour runtime is at light load; heavier loads will reduce runtime.
DuroMax XP13000HXT Tri Fuel Generator
Best for: Users who want fuel flexibility for long outages or remote worksites. The XP13000HXT runs on gasoline, propane, or natural gas. It delivers 13,000 watts and is driven by a robust 500cc OHV engine. It’s ideal when you need reliable power in varied fuel scenarios or when fuel availability is uncertain. Caution: Tri Fuel configurations may require more setup and maintenance to switch fuels safely.
DuroMax XP13000EH Dual Fuel Portable Generator
Best for: Homeowners who want the convenience of dual-fuel operation with electric start and transfer-switch readiness. This generator creates 13,000 watts of power and supports gasoline or propane operation, helping you adapt during fuel shortages or price spikes. It’s designed for whole-home backup and RV-ready use. Caution: dual-fuel units can be heavier and may require more frequent maintenance checks for fuel system components.
Westinghouse 12500 Watt Dual Fuel Back-Up Generator
Best for: Homes needing reliable dual-fuel power with transfer-switch capability. This unit can deliver 12,500 peak watts and up to 11,200 peak watts on propane, with 9,500 running watts on gasoline. It includes a remote-start option, a digital hour meter, and a VFT display for real-time status. Caution: propane performance may differ from gasoline, especially under heavy loads.
Buying Guide
What to consider when choosing a 22000 watt class portable generator:
- Power needs: Match peak watts to starting surges and running watts to daily loads. For whole-home backup, prioritize models around or above 15,000 running watts with multiple outlets.
- Fuel type and availability: Gasoline offers quick availability, while dual- or tri-fuel units add flexibility during fuel shortages or price spikes.
- Run time and tank size: Larger tanks extend runtimes at moderate loads. Consider idle control features that save fuel when loads are light.
- Starting method: Electric start with a remote key fob is convenient for frequent use; recoil start is more traditional but less convenient.
- Outlet configuration: Ensure enough 120V outlets for household devices and the appropriate 30A/50A receptacles for transfer switches or RVs.
- Safety features: Automatic CO shutdown, low-oil shutoff, and protected outlets reduce risk during outages.
- Portability: Heft and wheel kits matter for frequent relocation. Heavier models may require assistance for transport.
- Maintenance and service: Look for engines with durable components (e.g., OHV, cast-iron sleeves) and indicators like voltage/frequency displays for maintenance planning.
What else matters for selection
- Transfer-switch readiness: If you plan to power a house safely via a transfer switch, verify outlet types and compatibility with your system.
- Noise level: Higher-watt generators can be louder; check for consumer-friendly noise ratings if you’ll run near living spaces.
- Warranty and support: Consider brand availability and parts supply in your area for long-term reliability.
FAQ
- What does “peak watts” mean?
Peak watts indicate the maximum surge power a generator can deliver for a short time, typically needed when starting motors or appliances with high inrush. Running watts reflect continuous output during normal operation.
- Is dual-fuel better than single-fuel?
Dual-fuel offers flexibility and can be advantageous when one fuel becomes scarce or expensive. Ensure the unit is designed for easy switching and safe operation.
- Can I run a whole house on these generators?
Some models rated around 12,500–18,000 running watts can back up essential circuits or a portion of a home. For whole-house backup, a higher continuous wattage and proper transfer-switch installation are recommended.
- What is CO shutoff safety?
CO shutoff sensors automatically stop the generator if dangerous carbon monoxide levels are detected, reducing risk in enclosed spaces.
- Are propane models as reliable as gasoline?
Propane can be cleaner and longer-lasting for storage, but performance may vary with weather and ambient temperature. Choose a unit that suits your typical fuel availability and maintenance plan.
