Features
  • Dual Fuel Versatility & Power

    Choose your fuel source: Gasoline (4.4kW Surge/3.6kW Rated) or LPG (4.0kW Surge/3.3kW Rated). This flexibility ensures you have power during emergencies when gas stations are closed, utilizing the long shelf life of propane.

  • 223cc 4-Stroke Engine

    Powered by a heavy-duty OHV single-cylinder engine with a forced air-cooling system. Designed for high-demand tasks, it delivers a massive 30A Max AC Amperage (Gas), making it capable of starting high-induction motors and power tools easily.

Questions & Answers
  • How many hour run with propane

    With a standard 20‑lb propane cylinder, the generator runs approximately 6 hours at 100% full load (fuel consumption: 3.31 lbs/hour). Runtime will be longer under lighter loads. For reference, on gasoline with the 1.6‑gallon tank, runtime is 8 hours at 25% load. Note: When both fuel sources are connected, the generator prioritizes propane automatically.

    Answered by powersmart
  • Can this power a well pump, freezer and refrigerator?

    Yes. The generator delivers 3,600W running / 4,400W surge on gasoline – sufficient to handle all three. The surge capacity covers motor startup spikes for pumps and compressors. For best results, start the pump first, then plug in the other appliances to avoid simultaneous peak loads.

    Answered by POWERSMART
  • Can it run two large TV's refrigerator and a fan?

    Yes, absolutely. This generator provides 3600 running watts, while your listed appliances (two large TVs, a refrigerator, and a fan) typically draw only about 300–1400W total. Even with the fridge's startup surge, the 4400 surge watts can handle it with ease.
