Yamaha's industry-leading inverter generator is the ultimate in lightweight portable electricity. Features Pulse Width Modulation that produces pure sine-wave voltage, resulting in clean electricity that's perfect for anything from sensitive electronic equipment to computer-controlled appliances and power tools. Generator is built with sound-absorbing materials, newly designed USFS-approved spark-arrestor muffler, and revolutionary Yamaha engine to keep noise levels below 58dBA max. Smart Throttle™ automatically adjusts engine speed to match the electrical load required resulting in quieter operation and greater fuel efficiency. Electrical overload breakers prevent generator damage should an overload take place. Engine is air-cooled, 4-stroke, single cylinder OHV. Additional features include an Oil Watch Warning System to prevent engine damage, a 12-volt DC outlet and included cables to charge any 12-volt battery.
