Summary
The Firman W03386 is a 3,300-watt inverter generator built for RV camping, emergency backup, and light job site work. Its 3,650-watt peak capacity handles startup surges from air conditioning units, refrigerators, and power tools without strain. Because the unit runs on gasoline with a 1.8-gallon tank, users get up to 9 hours of runtime at 25% load before refueling. The inverter topology and sub-3% THD output means laptops, smartphones, and sensitive electronics charge safely without voltage spikes that damage circuitry. At 58 dB, it operates at conversational volume, making it acceptable for residential neighborhoods and campgrounds where noise restrictions apply. This is a mid-sized workhorse for users who need portable power without the weight penalty of larger stationary units.
The Ryobi RYi6522 is a 6500-watt open frame inverter generator designed to provide reliable power for various applications, including RVs, home backup, and job sites. It features a 298cc OHV engine delivering 6500 starting watts and 5500 running watts, CO Detect carbon monoxide shutdown sensor for added safety, and Pure Sine Wave Technology to safely power sensitive electronics.
