Buying Guide: Key Considerations For Dual Fuel Generators
Power needs: Assess the total wattage of appliances and circuits you must run during an outage. Choose a model with sufficient peak and running watts plus a margin for startup surges on compressors, pumps, and tools.
Fuel options: Dual fuel units offer gasoline and propane, enhancing availability during long outages. Propane storage is safer and has a long shelf life, while gasoline often provides higher immediate output.
Safety features: Look for CO sensors, automatic shutdown on low oil, and proper enclosure cooling. Transfer switch readiness simplifies connection to home circuits and can prevent backfeeding.
Portability vs. capacity: Larger generators deliver more power but are heavier and noisier. For mobility, prioritize lighter units with efficient running times; for backup power, prioritize higher wattage and robust fuel systems.
Outlets and accessories: Ensure the generator has a suitable mix of 120V, 240V, RV, USB, and parallel-kit compatibility if you plan to expand power with another unit. A fuel gauge and hour meter are helpful for planning maintenance.
Maintenance and durability: Copper windings, cast-iron sleeves, and corrosion-resistant components contribute to longevity. Regular oil changes, air filter care, and battery maintenance for electric-start models extend life.
