Honda EG4000 Features
Advanced technology for consistent power and performance
The EG4000 uses Honda's exclusive DAVR (Digital Automatic Voltage Regulator). The DAVR is designed to hold the voltage stability within a +/- 1% range during operation. This provides more consistent power.
CO-MINDER: Advanced Carbon Monoxide Detection System
CO-MINDER™ continuously monitors carbon monoxide (CO) levels. It automatically shuts down the generator before detected CO levels near the generator become dangerously high.
Powerful Honda commercial OHV engine
Legendary Honda commercial-grade OHV engines are reliable, easy-to-start and incredibly rugged.
120/240V Selector switch - More usable power, more flexibility
Choose between using both 120 and 240 Volts, or 120 Volts only. This allows for the total generator output to be available through any of the 120 volt outlets, limited only by the capacity of the individual outlet. This enables you to power units with larger wattage requirements.
Runs 14.8 hours @ 50% load (6.3 gal.)
Keeps you working, all day long.

You can rest easy, knowing your generator is covered from top to bottom for 3 full years.
