Summary
The Firman W03382 is a 3300-watt inverter generator built around a 193cc OHV 4-stroke engine with a cast iron sleeve. This wattage class handles mid-range household loads: a microwave, refrigerator, and several power tools simultaneously, but not a central air conditioner or electric water heater. The inverter topology keeps total harmonic distortion below 3 percent, which means laptops, televisions, and phone chargers run safely without risk of damage from voltage spikes. At 91 pounds and 23.2 by 17.8 by 17.9 inches, it occupies roughly the footprint of a large toolbox. The dual starting system (recoil and electric) eliminates the frustration of pull-cord failures. This is a practical workhorse for RV owners, job site supervisors, and homeowners who need portable backup power without sacrificing clean electricity.
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.
