Yamaha EF1000iS

The Yamaha EF1000iS inverter generator is the ultimate in lightweight portable electricity. The F1000iS - with its inverter system - features Pulse 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.
  
• 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.
