Buying Guide For Large Dual Fuel Portable Generators
To select the best large dual fuel portable generator, consider these key factors:
Power Output
Wattage is critical to ensure the generator can handle your power needs. Calculate the total starting and running watts of your essential appliances and devices. For whole home backup, generators over 10,000 watts are recommended.
Fuel Flexibility
Dual fuel models run on both gasoline and propane, giving you options easier to store and less prone to spoilage. Propane burns cleaner and lasts longer in storage than gasoline, which may influence your choice based on availability and environmental concerns.
Starting Method
Most large generators feature electric start for convenience, sometimes with remote controls. This feature saves time and effort compared to manual recoil starts, especially during emergencies.
Run Time and Fuel Tank Capacity
Look for generators with larger fuel tanks for extended runtimes. Some units can run for 12 hours or more on a single tank of gasoline or propane, reducing the frequency of refueling.
Safety Features
Carbon monoxide detectors and automatic shutdown functions add critical safety for home use. Transfer switch readiness ensures your generator integrates safely with your home electrical system, preventing backfeed hazards.
Portability
Larger generators can be heavy. Check for models with wheels and telescoping handles to simplify transport. This is especially important if you plan to move your generator between locations or use it for outdoor activities.
Outlet Selection
Ensure the generator has the proper outlets for your needs, including standard household receptacles, RV plugs, and 240V options for larger appliances.
By weighing these considerations and comparing top models like the DuroMax XP15000HX and Westinghouse 14500 Peak, you can find a powerful dual fuel generator suited for your home, RV, or job site backup power requirements.
