The Yamaha EF2400iS is a light weight user friendly generator. Its small compact design has a lot to offer. This model is also environmentally friendly.  Powered by a 171cc Yamaha engine, it will run 9 hours on a  tank of fuel. Larger units consume more fuel and expel twice the emissions of the EF2400iS. If you are environmentally conscious; put your mind at ease.

This may be Yamaha’s best work. The small compact design is quite and yet powerful enough to meet all of your energy needs.  The EF2400iS is rated at 2000 watts of continuous output. This is an ideal power source for microwaves, watching television or running your AC as you cool off on a hot summer’s day. It can safely power computers and sensitive electronics using an inverter system with Pulse Width Modulation (PWM) Control. With a run time of 9 hour per fill up; the EF2400iS can supply power throughout the night, thanks to Smart Throttle, a technology that varies engine speed based on load.  This improves fuel economy and reduces noise.  It has a Super-quiet Muffler with USFS-approved Spark Arrestor.  This Yamaha portable generator produces only 53 decibels of noise and eliminates errant sparks, making it campsite friendly.  Outdoor activities are all about fun and the Yamaha EF2400iS can make it happen.
