Summary
The Firman W03381 is a 3300-watt inverter generator built around a 193cc OHV 4-stroke engine with a cast iron sleeve. This wattage puts it in the mid-range portable segment, capable of powering a refrigerator, microwave, and several household circuits simultaneously, or running a single large tool on a job site. The 3650-watt starting capacity handles the inrush demand of compressors and air conditioning units. Because the W03381 runs on gasoline with a 1.8-gallon tank, users will find a 10-hour runtime at 25% load, which translates to roughly 2.5 hours of continuous full-load operation before refueling becomes necessary. The inverter topology and 3% THD output mean sensitive electronics like laptops, phones, and televisions receive stable, clean power without risk of damage. At 58 decibels, this generator operates at a volume comparable to normal conversation, making it suitable for residential neighborhoods and RV parks where noise restrictions apply.
The AIVOLT VS4350101 is a gasoline inverter generator with a rated wattage of 3450W and a peak wattage of 4300W.
