With a 0.5-quart oil capacity (included 10W-30) and a low oil shut-off sensor, this inverter operates at an ultra-quiet 61 dBA from 23', which is about as loud as normal speech. The no-tool access panel and oil drain tube allow for easy maintenance. Confidently connect your sensitive electronics since this inverter produces Clean Power (less than 3% THD).The Quick-Touch Panel offers fast access to all your controls. The Intelligauge with Power Meter monitors voltage, frequency, and operating hours with ease, while Economy Mode monitors power consumption in real time to reduce engine wear and tear. As the electrical load is reduced, the inverter reduces engine speed, providing quieter operation, extended engine life, and higher fuel economy. The covered outlets included are a 120V 30A RV outlet (TT-30R), a 120V 20A household duplex outlet (5-20R), and a 12V regulated automotive-style outlet. Buy this EPA-certified inverter generator with confidence. Champion Support and their nationwide network of service centers will back up your purchase with a 3-year limited warranty and FREE lifetime technical support. CO Shield technology monitors the accumulation of carbon monoxide (CO), a poisonous gas produced by engine exhaust when the generator is running. If CO Shield detects unsafe elevated levels of CO gas, it automatically shuts off the engine. CO Shield is not a substitute for an indoor carbon monoxide alarm or for safe operation. DO NOT allow engine exhaust fumes to enter a confined area through windows, doors, vents, or other openings. Generators must ALWAYS be used outdoors, far away from occupied buildings with engine exhaust pointed away from people and buildings. Meets the requirements of ANSI/PGMA G300.SpecsDimensions: 23.5"L x 18"W x 20.1"HWeight: 92.4 lbs.
