Honda's inverter technology means stable, clean power in a smaller, lighter package. The precision of Honda's inverter technology ensures our inverter generators produce power that is as reliable as the power you get from your outlets at home. Thanks to our exclusive Eco Throttle System, the EU30iS offers great fuel efficiency. Runs from 7.2 to 20 hours on a single tank, depending on the load. This makes it great for overnight power.So quiet, your neighbors will thank you. The EU30iS operates at 50 to 57 dB(A), which is less noise than a normal conversation. This makes it ideal for camping, RV power and any other activity that requires quiet operation.The EU30iS has a 12 Amp DC outlet for use when charging 12 volt  batteries. (Requires an optional charging cord.)Need more power? Add a second EU3000iS for additional power. Two identical models can be paralleled with an optional cable.
