The EF1000iS weighs only 12.7kg and is equipped with a new 4-stroke OHV 50cc engine. The Yamaha exclusive double coil system gives better fuel economy, a continuous running time of 12 hours and less noise. Designed to supply commercial-equivalent power, the EF1000iS is compact and combines a convenient carry handle making it extremely portable. Noise Block, acoustically designed sound reduction system helps to make the EF1000iS the quietest portable generator in its class.

The EF2400iS is a model that brings the reliable Yamaha inverter technology used on the highly acclaimed EF2800i to the 2kVA class. When we built our latest inverter generator, we listened to exactly what our customers wanted. Not only is it super-quiet (54-59dBA @ 7m), it only weighs 32 kilos and produces 2400 watts of maximum power. Cleaner, quieter and more powerful, the EF2400iS is the next step forward in generator technology.
