12,000 Watt Tri-Fuel Inverter Generator Electric Start 120V 240V Super Quiet LPG Natural Gas Portable Residential Home Use
Description
The Tomahawk Power TG12000iT is a heavy-duty tri-fuel inverter generator built for homeowners, contractors, and emergency preparedness professionals who refuse to be left in the dark. With 12,000 peak watts and 11,500 rated running watts on gasoline, this machine delivers enough power to keep HVAC systems, sump pumps, refrigerators, freezers, and sensitive electronics running without missing a beat. True tri-fuel capability means you can switch between gasoline, propane (LPG), or natural gas - giving you flexibility when fuel availability is uncertain during storms or extended outages.
Advanced inverter technology keeps Total Harmonic Distortion at or below 3%, making this generator safe for laptops, TVs, smart home devices, and other electronics that standard generators can damage. At just 65 dB at 7 meters, it operates quietly enough for residential neighborhoods, RV parks, and food truck operations alike. Whether you're powering a whole home, a job site, or an off-grid setup, the TG12000iT is engineered to deliver reliable, clean power wherever you need it most.
Key Features
- 12,000 Peak Watts / 11,500 Running Watts (Gas): Handles heavy startup loads from HVAC units, sump pumps, and large appliances while maintaining steady continuous output.
- Tri-Fuel Capability (Gas / LPG / Natural Gas): Seamlessly switch between three fuel sources - ideal for emergencies, long-term backup, and situations where one fuel type may be unavailable.
- Electric & Remote Start: One-touch electric ignition gets the generator running instantly - no pull cord required. Remote start adds even more convenience.
- 120V / 240V Multi-Outlet Panel: Four 120V outlets, one 30A 120/240V outlet, and one 50A 240V outlet provide flexible power distribution for whole-home or job site use.
- Super Quiet - 65 dB at 7m: Inverter technology dramatically reduces noise output, making it neighborhood-friendly and suitable for RV parks and residential areas.
- Clean Inverter Power - THD ≤3%: Stable, low-harmonic output protects sensitive electronics like computers, TVs, and smart home devices from power fluctuations.
- 550 cc OHV 4-Stroke Engine: The 196F/P-1 engine runs at 3600 RPM and is built for consistent, long-term performance under heavy load.
- 8.6-Hour Run Time @ 25% Load: The 6.9-gallon (25L) fuel tank delivers extended runtime to get you through overnight outages without refueling.
- Heavy-Duty Steel Frame with Wheels: Rugged construction and integrated mobility features make it easy to move and position despite its substantial 271 lb frame.
- CARB Compliant: Meets California Air Resources Board standards as qualifying construction equipment - approved for use in California.

Why You'll Love It
When a storm knocks out the grid, the TG12000iT keeps your household running exactly as it should - lights on, food cold, heat or AC maintained, and your devices charged. The tri-fuel design means you're not scrambling for gasoline at a packed station when a hurricane is inbound; propane tanks or a natural gas line connection have you covered. The inverter technology isn't just a spec on a sheet - it's what separates this generator from cheaper open-frame alternatives and makes it genuinely safe for powering the electronics your family depends on every day.
Contractors and job site operators will appreciate the 50A 240V outlet and the robust steel frame that holds up to the punishment of daily professional use. Homeowners will appreciate how quietly it runs compared to conventional generators of the same size. Backed by Tomahawk Power's reputation for durable outdoor power equipment, the TG12000iT is the kind of investment you make once and rely on for years - whether it runs a dozen times a year during outages or sits ready on standby until the moment you truly need it.

FAQ
What fuels can this generator run on?
The TG12000iT is a true tri-fuel generator, meaning it can run on gasoline, propane (LPG), or natural gas. You can switch between fuel sources depending on what is available, making it an excellent choice for emergency preparedness when one type of fuel may be difficult to obtain.
Is this generator safe to use with sensitive electronics like computers and TVs?
Yes. The inverter technology in the TG12000iT produces clean power with a Total Harmonic Distortion (THD) of 3% or less. This is the standard threshold considered safe for sensitive electronics, including laptops, computers, televisions, and smart home devices. Standard open-frame generators typically produce much higher THD, which can damage or shorten the lifespan of these devices.
How does this generator ship, and do I need to do anything to prepare for delivery?
Due to its size and weight (365 lbs packaged), this generator ships via freight truck on a pallet. You will be contacted to schedule a delivery appointment. Shipping to a business address can reduce transit time by 1-2 days. Make sure you have a way to move the unit from the delivery point - a pallet jack or forklift is recommended due to the weight.
Can this generator power a whole house?
With 11,500 rated running watts on gasoline and a 50A 240V outlet, the TG12000iT can handle most whole-home essential loads, including HVAC systems, refrigerators, freezers, sump pumps, lights, and electronics. For very large homes or homes with multiple large appliances running simultaneously, it is recommended to prioritize essential circuits using a transfer switch. Consult a licensed electrician for whole-home connection.
How loud is this generator compared to a standard generator?
The TG12000iT operates at 65 dB measured at 7 meters under 25% load. For reference, that is roughly equivalent to a normal conversation or an air conditioner - significantly quieter than traditional open-frame generators of similar output, which often exceed 75-80 dB. This makes it one of the more neighbor-friendly options in its power class.
Does this generator require assembly?
The generator arrives largely pre-assembled. You will typically need to add oil before the first use, attach the wheel kit and handle if not pre-installed, and connect your fuel source. Detailed setup instructions are included with the unit.
