Honda Portable Silent Generator EU20i The quietest in its class !! Delivering 2000 watts of portable power. At the flick of a switch this feature only runs the engine as fast as the load demands, enabling the EU20i to run for over ten hours on a single tank of fuel @ 1/4 load , with minimal noise and fuel cost and maximum engine life. Power is passed through a special microprocessor which “smooths” the power output so computers and other sensitive electrical equipment can be run safely on this model. The low noise design only produces 52db @ 7m, equivalent to the noise level in a typical business office.
