The GG4000N achieves higher power output in a compact body and is an advanced version of the GG2000N. It also adopts a 15L steel fuel tank, which is impact-resistant and aging-resistant, suitable for long-term storage and outdoor operations. Equipped with the UP170 single-cylinder four-stroke OHV engine, the peak power has been increased to 4.0kW, with a rated output of 3.6kW (60Hz), which is sufficient to simultaneously drive medium-load equipment such as water pumps, welding machines, and small air conditioners. Under 50% load, a single refueling can sustain operation for 10 hours, covering the continuous power demand for most of the day. The net weight of the entire machine is only 41kg, almost the same as the GG2000N, but the power has increased by nearly 60%, achieving an upgrade of "stronger power in the same volume". The hand-pulled recoil start structure is simple and reliable. The noise at A distance of 4 meters is 96dB(A). It is recommended to use it in a well-ventilated area. Whether it's temporary power supply for construction sites, driving farm equipment, or serving as an emergency backup for medium-sized households, the GG4000N offers superior power performance compared to models of the same size with its lightweight body.
