| Summary | The Champion Power Equipment 201122 is a 2500-watt dual fuel inverter generator featuring CO Shield® carbon monoxide auto shutoff system. It is one of the lightest in its class, operating at a quiet 53 dBA from 23 feet, and offers up to 11.5 hours run time on gasoline or up to 34 hours on propane. | The Firman W01784 is a 1700-watt inverter generator built around a compact 80cc OHV 4-stroke engine. This wattage class handles household essentials like refrigerators, power tools, and multiple small appliances simultaneously, but cannot run a central air conditioner or large workshop equipment. The 2100-watt peak gives it enough surge capacity to start compressors and induction motors without stalling. Because the unit weighs only 45.9 pounds and measures 20 by 12.1 by 16.7 inches, users can load it into a truck bed or carry it to a job site without mechanical assistance. The 0.9-gallon fuel tank and 9-hour runtime at 25% load mean a full tank covers a typical workday without refueling. At 54 decibels, it runs quieter than a lawnmower, making it suitable for residential neighborhoods and early-morning camping. |
