Generac CA GP6500 portable generator with COSENSE Technology provides lots of power while protecting you and your home from carbon monoxide (CO) poisoning. If you inadvertently use the GP6500 indoors or in an enclosed space, COSENSE® WILL automatically shut off your unit when increased CO is detected. This unit also offers PowerRush Advanced Technology, which delivers more than a 40% increased starting capacity*. Generac's OHV engine and large-capacity steel fuel tank ensures long engine life and run times, while the steel tube cradle provides added strength. The low-oil feature protects the generator from damage. The GP6500 can be easily transported across rough or difficult terrain with the heavy-duty wheels and easy fold-down handle. Even maintenance is a breeze, with the hour meter keeping track of necessary upkeep at regular intervals.
