Features may include:

  • The EF1000iS weighs in at 27.9 pounds, making it extremely portable.
  • Noise Block is Yamaha's acoustically engineered sound reduction system which helps make the EF1000iS among the quietest portable generator in its class. (47 dBA to 57 dBA – ¼ rated to rated load).
  • Gasoline petcock lets you shut off the gas to run the carb dry for storage and helps prevent stale gas problems.
  • The EF1000iS features Smart Throttle, a load sensing rpm control that allows greater fuel efficiency and noise reduction by automatically adjusting engine speed to match the load. It will run up to 12 hours at ¼ rated load on a tank of gas.
