The Yamaha EF1000iS inverter generator is the ultimate in lightweight portable electricity. The EF1000iS - with its inverter system - features Puulse Width Modulation (PWM). That means these generators deliver clean power so you can use them confidently for powering computers, solid-state appliances with built-in computer functions or microcomputer-controlled power tools.

  • Lightweight Design / Easy to Carry - Newly designed exterior and compact lightweight inverter unit reduces weight to 27.9 lbs. Lightest weight generator in its class.
  • Legal for sale in all 50 states - Meets CARB emission regulations.
  • Noise Block Acoustically designed sound reduction system - Molded casing, noise-absorbing glass wool construction and a newly designed muffler produce unbeatable noise reduction.
  • Long Run Time - Runs continuously for up to 12 hours without refueling (at 1/4 load with "Economy Control" function on).
  • Smart Throttle Load sensing throttle control - Automatically adjusts engine speed to precisely match load, resulting in greater fuel efficiency and noise reduction.
  • 12 Volt DC Output (Battery Charging Cables Included) - Recharge 12 volt batteries for RV, auto, marine, aircraft, etc.
  • Inverter System with Pulse Width Modulation - Industry-leading system produces higher-quality and cleaner electricity. Results in pure sine wave as clean or cleaner than commercial power and can operate products with built in microcomputers.
  • Exclusive Dual Coil Alternator Stator - Lower engine speed. Reduced noise, fuel consumption and engine wear.
  • Centralized Control Panel - Control panel enables easy access to controls.
  • Fuel Petcock - Reduces carburetor contamination by turning off gasoline flow and allowing the carburetor to run dry.
  • OHV 50cc Engine (overhead valve) - Provides improved efficiency, increased reliability, low oil consumption and noise-reducing operation.
  • Large Fuel Fill Access - Wide mouth fuel fill reduces spilling and overflow during refueling.
