Dual fuel generators offer the flexibility and convenience of using two different types of fuel, typically gasoline and propane, in a single generator. This versatility makes them a popular choice for emergency backup power, outdoor events, and job sites where fuel availability might vary. Whether you’re preparing for unexpected power outages or need a reliable power source for recreational activities, a dual fuel generator can be an excellent investment. This guide will help you navigate the key features to consider when selecting the best dual fuel generator for your needs.

Key Features to Consider

Fuel Versatility and Efficiency

  • Fuel Types: Most dual fuel generators run on gasoline and propane. Each fuel type has advantages in terms of availability, cost, storage life, and energy efficiency.
  • Fuel Switching: Check how easily you can switch between fuel types and whether the generator allows for on-the-fly switching without powering down.

Power Output

  • Wattage: Determine the wattage you need by calculating the total power requirements of all devices and appliances you plan to run simultaneously. Consider both starting (surge) watts and running watts.
  • Efficiency: Propane often provides a cleaner burn and longer storage without degradation compared to gasoline. However, the energy content per gallon is lower, which may affect the maximum power output and runtime.


  • Size and Weight: Dual fuel generators tend to be heavier and bulkier due to additional components. Look for models with wheel kits and handles for easier mobility.
  • Design: Compact designs are preferable for recreational use and storage, but larger units may be necessary for higher power needs.

Noise Level

  • Quiet Operation: Consider the noise level, especially if you plan to use the generator for camping or in residential areas. Some models are designed to operate more quietly, minimizing disturbance.

Durability and Build Quality

  • Construction Quality: Robust construction is crucial for the durability of a generator, especially if it will be used in various outdoor environments.
  • Weather Resistance: Weatherproof features are important for ensuring the generator performs well under different climatic conditions.

Additional Features

  • Display and Controls: Modern generators often feature digital displays and easy-to-use control panels that show fuel levels, power output, and operational hours.
  • Safety Features: Look for safety features such as automatic low-oil shutoff, overload protection, and circuit breakers to ensure safe operation.
