FAQ
What is the difference between starting watts and rated watts?
Starting watts (5500W) is the surge power the generator produces for a brief moment to start motors and compressors - things like power tools, drills, and air conditioners require a higher wattage spike to get going. Rated watts (5000W) is the continuous power output the generator can sustain during normal operation. When calculating what you can run, use the rated wattage of 5000W as your working budget.
Can this generator safely power sensitive electronics like laptops and speakers?
Yes. The TG5500i uses advanced inverter technology that produces clean, stable power with less than 3% total harmonic distortion (THD). This is well within the safe threshold for sensitive electronics including laptops, computers, audio equipment, and other devices that can be damaged by "dirty" power from conventional generators.
How does parallel capability work?
The TG5500i supports parallel operation, meaning you can connect two TG5500i units together using a parallel kit to effectively double your power output. This is ideal for situations where a single generator's output isn't enough - such as large job sites, RV setups with heavy loads, or events requiring high wattage. Both units work in sync to share the load.
How loud is this generator?
The TG5500i operates at 62 dBA, which is comparable to a normal conversation or background office noise. This makes it significantly quieter than conventional generators, allowing use in noise-sensitive environments like campgrounds, residential job sites, and events.
Is this generator CARB compliant - can I use it in California?
Yes. The TG5500i is CARB (California Air Resources Board) compliant, meeting strict California air quality standards. It qualifies under CARB's exception for construction equipment, making it legal for use in California. Always check local regulations for your specific application.
What does Eco Mode do and when should I use it?
Eco Mode automatically adjusts the engine's speed based on the electrical load being demanded at any given moment. When your power needs are low, the engine throttles back to conserve fuel and reduce noise. When demand increases, it ramps up automatically. Using Eco Mode whenever possible extends your run time up to 8 hours on a 4-gallon tank and reduces overall fuel costs.
