The Honda EG4000 generator offers a more economic, portable generator option. It has a long run time of up to 15.7 hours on 6.3 gal of gas. You can 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.
