At Yamaha, we like to take a good thing and figure out how to make it even better.

Just take the EF1000iS, the smallest member of our trusted line of inverter generators. As in, just take it anywhere you want: Weighing in at just 12.7 kg, it can be carried with one hand. Inverter technology means that this lightweight 4-stroke beauty combines quality power and clean exhaust that's in step with the world's strictest emissions standards.
