The ultimate in lightweight portable electricity! Yamaha Portable Generators give you the power you need where you need it. Pulse Width Modulation (PWM) delivers clean power so you can use it confidently for powering computers, solid-state appliances with built-in computer functions or microcomputer-controlled power tools. Lightweight and easy to carry. Noise Block acoustically designed sound reduction system produces unbeatable noise reduction. Smart Throttle Load sensing throttle control automatically adjusts engine speed to precisely match load, resulting in greater fuel efficiency and noise reduction. Oil Watch warning system and electrical overload breaker help prevent engine damage. Super-quiet muffler with USFS-approved spark arrestor eliminates errant sparks. Overhead valve engine with cast iron cylinder liner is efficient, reliable, powerful providing long life and excellent heat dissipation. DC output recharges 12 volt batteries for RV, auto, marine, aircraft, and more with included battery cables.

The Yamaha EF1000iS inverter generator supplies clean, high quality power. The EF1000iS – with its inverter system – features Pulse Width Modulation (PWM) so voltage stability is within ± 1%, and frequency stability is ± 0.1 HZ. Its pure sine wave is as clean as or cleaner than public utilities power.

At 27.9 lbs., it is the lightest weight generator in its class. Runs continuously for up to 12 hours without refueling (at 1/4 load with “Economy Control” function on). Exclusive dual coil alternator stator means lower engine speed, reduced noise, fuel consumption and engine wear. Centralized control panel enables easy access to controls. Fuel petcock reduces carburetor contamination by turning off gasoline flow and allowing the carburetor to run dry. Large fuel fill access features wide mouth for reduced spillage and overflow during refueling.
