Yamaha Motor Corp. introduces the EF4500iSE, a mid-size portable generator capable of running a small air compressor, circular saws and other hand tools. The EF4500iSE is designed for less noise and better fuel economy, and features an engine that allows for a low engine speed of 2,600 rpm. This low engine speed in turn reduces fuel consumption, noise, vibration and engine wear. In addition, the EF4500iSE features an easy-to-transport four-wheeled base, a fuel level gauge and an oil warning system to prevent engine damage.
