  • The EF1000iS weighs in at27.9 pounds, making it extremely portable.
  • Noise Block is Yamaha’s acoustically engineeredsound reduction system which helps make theEF1000iS among the quietest portable generator inits class. (47 dBA to 57 dBA – ¼ rated to rated load)
  • The EF1000iS features Smart Throttle, a load sensingrpm control that allows greater fuel efficiency andnoise reduction by automatically adjusting enginespeed to match the load. It will run up to 12 hours at¼ rated load on a tank of gas.
  • The Yamaha EF1000iS inverter generator suppliesclean, high quality power. The EF1000iS – withits inverter system – features Pulse WidthModulation (PWM) so voltage stability iswithin ± 1%, and frequency stability is ± 0.1 HZ.Its pure sine wave is as clean as or cleaner thanpublic utilities power.
  • The Auto Warm-up feature automatically increasesengine speed for 4~6 minutes to ensure smoothpower delivery during cold start ups.
  • Lightweight, easy to carry design — Compact lightweightalternator reduces weight to 27.9 lb., the lightest weight inits class.
  • Noise Block, acoustically designed sound reduction system —Molded casing, glass wool insulation, and an advanceddesigned muffler provide unbeatable noise reduction.
  • Smart Throttle, load sensing rpm control — Greater fuelefficiency and noise reduction by automatically adjusting enginespeed to match the load.
  • Auto Warm-up — Automatically increases engine speed for 4~6minutes to ensure smooth power delivery during cold start ups.
  • 12 Volt DC output, battery-charging cables included — Recharge12-volt batteries for RV, auto, marine, etc.
  • Exclusive dual coil alternator stator — Greater output at a lowerengine speed for reduced noise, fuel consumption, and engine wear.
  • Centralized control panel — Easy access to controls.
  • Inverter system with Pulse Width Modulation (PWM)control — Can run products with built-in microcomputercontrolledelectric tools.
  • Gasoline petcock lets you shut off the gas to run the carb dry forstorage — Prevents stale gas problems.
  • 50cc Overhead Valve (OHV) engine — Noise-reducingoperation with improved efficiency, increased reliability, and lowoil consumption.
  • EPA & CARB Emission Engine Life Rating — Yamaha generatorshave the longest emission engine life ratings issued by theenvironmental Protection Agency and the California AirResources Board.
  • 50 state legal — Meets emmision regulations, including CARB.
