The dual-fuel technology of the Genmax GM7250iEDC allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 6,000W and a starting wattage of 7,250W. If propane-powered, it gives 5,500 rated watts and 6,500 starting watts. Moreover, since it is parallel capable (GM9000PK parallel cable not included), its power may be increased if linked to a second compatible unit.
