Best for space-constrained scenarios where portability matters; avoid this if you need the highest possible continuous output.
Buying Guide: Dual-Fuel Generators
Power needs: Match your required running and starting watts to the generator’s output. Higher wattage handles more appliances and tools simultaneously.
Fuel flexibility: Dual-fuel capability provides backup options—gasoline for peak performance and propane for extended storage and cleaner-burning operation.
Runtime and tank size: Larger tanks extend runtime but add weight and footprint. Consider loads and typical outage durations when sizing.
Starting method: Electric start and remote start improve convenience, especially in cold weather or during outages.
Portability vs. capacity: Portable units are easier to move but may offer less continuous power. Stationary-ready units provide higher wattage and transfer switch compatibility.
Safety features: Look for CO sensors, automatic low-oil shutdown, and proper grounding. Inverter technology helps protect sensitive electronics.
