Tomahawk TG5500i Overview
The Tomahawk TG5500i is an electric-start gas inverter generator for contractors, outdoor professionals and emergency preparedness. It provides 5,500 starting watts and 5,000 rated watts, using inverter technology to produce clean, stable power to job site tools and sensitive electronics alike.
A 312cc industrial-grade engine runs from a 4 gallon tank, with about 8 hours of run time at half load. ECO Mode improves fuel efficiency and reduces engine noise, and the generator measures 62 dBA. Outlets cover 120V, 120V twist-lock and 240V connections, and parallel capability links two units for added power.
The TG5500i weighs 122 pounds and measures 25 x 22 x 28 inches, with a 4 gallon tank that runs about 8 hours at half load. Oil capacity is 0.7 quarts of SAE 10W-30, and running amperage is listed as 41.7A at the 120V outlet and 20.8A at the 240V outlet. Starting takes only a push of a button.
Safety features include GFCI outlets, low oil shutdown and overload protection, and a 2-year warranty applies. The compact, lightweight design makes it easier to move, and parallel capability lets you link two units when more power is needed. Quiet operation makes it suitable for campsites, homes and noise-sensitive areas.
