Westinghouse 12500 Watt Dual Fuel Backup Generator
Best for mid-size homes that need dependable 120V and 240V output. This model runs 9500 watts on gasoline and 8500 watts on propane, with up to 12 hours of runtime from a 6.6-gallon tank. It starts remotely with a key fob and can be wired for a transfer switch, making it a strong choice for homeowners seeking a balance between power and convenience.
- Fuel options: Gasoline or propane
- Starts via remote or recoil/electric options
- Two 120V outlets and a 30A transfer switch connection
Best for: Homeowners who want high peak power and dual-fuel flexibility with switch-ready compatibility. Limitation: Propane run time is shorter than gasoline, so plan fuel strategy accordingly.
Westinghouse 13500 Peak Watt Tri-Fuel Generator
This tri-fuel option provides versatility for homes in areas with unreliable natural gas service or during extended outages. With 13500 peak watts on gasoline, 12500 peak on propane, and 10000 peak on natural gas, it offers robust options for varied fuel availability. It includes a long runtime (up to 19 hours on a large tank) and a CO shutdown feature for safety.
- Fuel options: Gasoline, Propane, Natural Gas
- Remote start and transfer-switch readiness
- CO shutdown and digital hour meter
Best for: Larger homes or households needing fuel flexibility and longer runtimes. Caution: Natural‑gas availability is burner-dependent; ensure gas line capacity meets load requirements.
Westinghouse 14500 Peak Watt Dual Fuel
Ideal for larger homes that require strong, steady power across a wide range of loads. It delivers 11,500 running watts on gasoline and 10,500 running watts on propane, with 14,500 peak watts. The 9.5-gallon tank supports up to 19 hours of operation, and the unit includes a fuel gauge and transfer switch readiness.
- High peak and running wattage for heavy loads
- Long runtime on gasoline; substantial propane efficiency
- Heavy-duty build with safety features
Best for: Homeowners needing substantial backup capacity for essential circuits and higher appliances. Limitation: Heavier and bulkier than compact portable options.
Champion 11,000-Watt Wireless Remote Start
Best for: Homeowners seeking convenience with remote operation and a quieter profile. It is a strong pick for smaller homes that still need reliable whole-house support. Limitation: Wireless start mechanisms may require battery maintenance for long outages.
MaXpeedingrods 3500 Watt Inverter
Best for: Outdoor use, campers, and light home backup where portability and low noise matter. Choose this if you need a compact, CO-sensor-equipped unit for essential minor loads. Limitation: Lower total wattage means it cannot handle large HVAC or multiple heavy appliances simultaneously.
Buying Guide: How To Choose The Right Home-Backup Generator
How much power do you need?
Calculate your essential loads and total wattage. Look for a generator with running watts that exceed your base needs by 20–30% to cover startup surges of appliances such as refrigerators and sump pumps.
Fuel options and runtime matter
Gasoline offers quick availability, while propane and natural gas can provide cleaner burning fuel without frequent refueling. Consider generators with large tanks and fuel gauges to maximize uptime during outages.
Transfer switch readiness
A transfer switch simplifies switching from grid to generator power. Ensure the model you choose includes or is compatible with a transfer switch panel for safe, code-compliant operation.
Starting system and noise level
Remote start is convenient for frequent outages. Inverter generators excel in quiet operation, which is beneficial for residential neighborhoods and nighttime use.
Portability vs. home backup focus
Compact models provide portability for events and camping, while larger units emphasize continuous power for home essentials. Choose based on how permanently you plan to rely on backup power and the space available for storage and ventilation.
Safety and regulatory considerations
Look for CO shutdown, rubber outlet covers, and proper ventilation. Verify the unit fits local electrical codes and that installation is performed by a qualified professional when connecting to a transfer switch or the home’s electrical system.
Summary of key buyer considerations
- Wattage needs vs. home load profile
- Fuel type availability and tank size
- Start method and noise tolerance
- Transfer switch compatibility and safety features
- Portability vs. endurance for whole-house scenarios
