The generator includes remote electric start and a CO alert feature that automatically shuts off the generator if unsafe carbon monoxide levels are detected. This balance of power, convenience, and safety features caters to users needing reliable and flexible backup power solutions.
Buying Guide for Dual Fuel Generators
When deciding if a dual fuel generator is worth it, consider these key factors:
- Fuel Flexibility: Dual fuel models allow you to switch between propane and gasoline. Propane burns cleaner and stores longer, while gasoline generally offers more power density. This flexibility can extend runtime and fuel availability during emergencies.
- Power Output: Match the generator’s surge and running watts to your power needs—essentially the combined wattage of appliances, tools, or RV equipment you plan to run. Larger homes need higher output, while occasional RV use may only require moderate power.
- Runtime and Fuel Capacity: Longer run times reduce refueling frequency. Look for fuel tank size and propane compatibility and consumption rates to understand how long the generator will operate continuously on each fuel.
- Starting Method: Ease of startup matters. Electric starts with remote key fobs provide convenience, especially in cold weather or emergency scenarios. Recoil starts serve as a reliable backup.
- Noise Level: For camping or residential areas, quiet operation is beneficial. Inverter generators often run quieter and provide cleaner power for sensitive electronics.
- Safety Features: Carbon monoxide (CO) shutdown systems are crucial for indoor or partially enclosed generator use to prevent toxic exposure.
- Portability and Size: Consider the generator’s weight and design for ease of transport. Lightweight inverter models suit frequent moves, while heavier standby generators offer more power but less mobility.
- Outlets and Compatibility: Check for multiple outlets including standard household plugs, RV outlets, and transfer switch readiness—important if integrating with home electrical systems.
- Brand Reliability and Warranty: Established brands like Westinghouse, WEN, and DuroMax provide confidence with robust engines and support. Warranties and customer service can affect long-term satisfaction.
