Tomahawk TG5500i 5500-Watt Inverter Generator
Power, Precisely Where You Need It.
Reliable power should feel effortless.
The Tomahawk TG5500i Inverter Generator combines robust 5,500-watt starting power with advanced inverter technology, quieter operation, and thoughtful portability—creating a versatile power solution for demanding projects, outdoor environments, recreational use, and backup applications.
At its core, a high-performance 312cc engine delivers dependable output, while advanced inverter technology produces clean, stable power with less than 3% total harmonic distortion—making the TG5500i suitable for powering everything from tools and equipment to more sensitive electronics.
Electric start simplifies operation. Eco Mode intelligently adjusts engine speed based on demand to conserve fuel. And when additional capacity is required, parallel capability allows two compatible TG5500i generators to work together.
It's substantial power, made more intelligent.
Power Without Compromise
With 5,500 starting watts and 5,000 rated watts, the TG5500i provides the capacity to support a wide range of equipment and applications.
From powering tools at a remote project site to supporting outdoor events, recreational activities, mobile businesses, or essential equipment when conventional power isn't readily available, the TG5500i is engineered to perform with confidence.
A generous 4-gallon fuel tank provides up to approximately 8 hours of runtime at half load, reducing interruptions when dependable power matters most.
Clean Power for Modern Technology
Not everything you connect to a generator is simply a tool.
Today's environments include computers, communications equipment, audio systems, and other electronics that benefit from consistent, stable power.
The TG5500i's advanced inverter technology delivers less than 3% total harmonic distortion, helping provide cleaner electrical output suitable for sensitive electronic devices as well as more traditional equipment.
It's a more considered approach to portable power—designed for the technology we rely on today.
Intelligent Efficiency
Power should be available when you need it without consuming more fuel than the moment requires.
With Eco Mode, the TG5500i automatically adjusts engine speed in response to the electrical load rather than operating continuously at maximum output.
The benefit is greater fuel efficiency, extended runtime, and reduced operating noise during lighter-demand applications.
More efficient operation. Less unnecessary consumption.
Quietly Capable
At approximately 62 dBA, the TG5500i is engineered for quieter operation than conventional open-frame generators.
That distinction matters whether you're working around others, enjoying an outdoor environment, supporting an event, or simply looking for capable portable power without unnecessary disruption.
The result is performance that makes its presence known through what it powers—not through excessive noise.
Effortless Starting
When portable power is needed, simplicity matters.
The TG5500i incorporates electric start for quick, convenient ignition, eliminating much of the effort traditionally associated with starting portable generators.
Combined with its ergonomic design, the TG5500i makes substantial power easier to access, operate, and transport.
More Power When the Moment Requires It
Some applications demand more.
With parallel capability, two compatible TG5500i generators can be connected to expand available power for higher-demand situations.
This gives you the flexibility to use a single generator for everyday requirements while retaining the ability to scale your power solution when circumstances change.
Engineered with Protection in Mind
Reliable power isn't simply about output. It's also about protecting the generator, connected equipment, and the people operating it.
The TG5500i incorporates thoughtful safety features including:
-
GFCI-protected outlets
-
Overload protection
-
Low-oil shutdown
-
Stable inverter-generated power
Together, these technologies add an additional layer of confidence whether the generator is being used professionally, recreationally, or around the home.
Portable by Design
Despite its substantial output, the TG5500i is designed with mobility in mind.
Its compact configuration and integrated ergonomic handle make transportation and storage more manageable, giving you the freedom to bring reliable power closer to wherever it's needed.
From project sites to outdoor environments, portability turns capability into convenience.
