Chicago Electric gas-powered generators range in peak power output between 900 and 16,000 watts, depending on the model. Usually, typical output during sustained operation is lower than the peak output. For example, 900-watt Chicago Electric generators output 800 watts during sustained operation, generally.
Many less-powerful Chicago Electric generators are all-in-one units that include a gasoline engine and generator in a single portable package. Some larger generators do not include their own gasoline engine, however. These larger generators are intended for use with an external engine and are often designed to be mated to tractors or other farm and construction equipment to produce power in remote locations.
