Buying Guide: Choosing the Best Gas Powered Backup Generator
Power Output and Capacity
Select a generator that provides sufficient running watts to power your essential appliances and devices continuously. Consider peak watts for handling surge power needs during startup. For whole-home backup, models above 10,000 running watts generally cover most appliances.
Fuel Type and Flexibility
Generators that support multiple fuel types like gasoline, propane, and natural gas offer greater versatility and fuel availability options, especially during emergencies. Dual or tri-fuel generators allow you to switch fuels depending on what’s accessible.
Run Time and Fuel Tank Size
Longer run times reduce the need for frequent refueling. Larger fuel tanks, often combined with fuel gauges, help you manage continuous power supply efficiently. Also, consider models with fuel-efficient or ECO modes that extend runtime and reduce noise.
Starting Mechanism
Electric start offers convenience, especially in emergencies, often combined with remote start capabilities. Manual recoil start is a backup option but can be less convenient. Look for models offering both options for reliability.
Portability and Weight
Portable generators are easier to move, ideal for outdoor and emergency use. Check weight and dimensions, and consider features like wheel kits or handles if transportability is important.
Safety Features and Outlets
Automatic low oil shutdown prevents engine damage. Carbon monoxide sensors enhance safety during operation. Multiple outlet types including GFCI-protected household plugs, transfer switch compatible, and RV plugs increase usability across devices.
Noise Level
Quiet operation is crucial for residential areas and campgrounds. ECO modes and inverter technology help reduce noise while maintaining power quality.
Properly assessing your power needs and key features ensures selecting a gas powered backup generator that delivers reliable, safe, and efficient power when you need it most.
