Buying Guide for Gas and Propane Generators
Choosing the right generator that runs on both gas and propane involves several important considerations:
Fuel Flexibility and Availability
Dual-fuel and tri-fuel generators provide flexibility to switch between gasoline, propane, and sometimes natural gas. Propane offers longer shelf life and cleaner emissions, while gasoline may deliver slightly higher power output. Consider your most accessible fuel and storage limitations when selecting a model.
Power Output: Peak vs. Running Watts
Generators list peak (surge) watts and running watts. Peak watts indicate short-term power for starting heavy appliances, while running watts show continuous power. Match the running watts to your essential devices plus some headroom for safety, especially for home backup usage.
Runtime and Fuel Tank Capacity
Longer runtime reduces the need for frequent refueling during outages. Tanks ranging from 6 to 9+ gallons can provide runtimes from 7 to 19 hours depending on load. Some models feature built-in fuel gauges to monitor fuel levels easily.
Noise Level and Portability
Consider how quiet the generator runs, especially for residential areas or campsites. Inverter generators generally operate more quietly and are lighter, while larger conventional units may be heavier but provide more power. Features like wheel kits and handles improve portability.
Starting Mechanism and Controls
Electric start with remote key fobs adds convenience compared to pull start mechanisms. Look for intuitive control panels, digital displays providing voltage and runtime data, and safety features like automatic low oil shutdown and carbon monoxide sensors.
Outlets and Transfer Switch Compatibility
Choose a generator with outlets matching your needs – standard household plugs, RV outlets, and transfer switch-ready connections to integrate with home electrical systems safely. Safety covers on outlets protect against moisture and debris.
Safety Features
Carbon monoxide shutdown sensors and low oil shutdowns protect you and the generator during operation. These features are important for peace of mind while running the generator indoors or near living spaces.
