Manufacturer overview
The 4000 watt portable gas generator is powered by a 223cc engine with low-oil shutdown. CO-Protect automatically shuts down the generator if carbon monoxide levels become unsafe or rapidly increase. Covered outlets, heavy-duty wheels, a fold-down handle, and a 1 1/4-inch steel tube frame prepare it for demanding transport and storage.
