Buying Guide for Dual Fuel Generators
When assessing whether a dual fuel generator is worth it, consider the following key factors to match your power needs and preferences:
Fuel Flexibility
Dual fuel capability allows you to switch between gasoline and propane based on availability, cost, or environmental considerations. Propane runs cleaner and often offers longer shelf-life, while gasoline is generally more accessible in an emergency.
Power Output
Determine the wattage needed for your essential appliances and devices. Look at both peak (starting) watts and running watts to ensure the generator can handle surge loads like motor startups and continuous power demands.
Portability and Noise Level
If you plan to use the generator for camping, tailgating, or RV trips, select models that are lightweight and feature handles or wheels. Consider quiet operation and inverter technology to reduce noise, especially in residential or recreational areas.
Starting Mechanism and Controls
Generators with remote electric start offer added convenience, especially when used in cold weather or during emergencies. User-friendly interfaces with digital displays help monitor fuel status, output, and maintenance schedules.
Safety Features
Look for generators that include carbon monoxide sensors and automatic shutdown functions for CO and low oil levels. This enhances user protection during operation in enclosed or semi-enclosed spaces.
Run Time and Fuel Tank Size
Longer runtimes reduce the need for frequent refueling. Larger fuel tanks or propane tanks contribute to extended operation during power outages or work activities.
Outlet Variety and Compatibility
Ensure the generator includes outlets that match your power needs, such as standard 120V household plugs, RV plugs (TT-30R or 14-50R), and transfer switch connections for home wiring integration.
By balancing these factors and choosing a reliable brand like WEN or Westinghouse, a dual fuel generator can provide versatile and secure power backup, making it a worthwhile investment for many.
