| Summary | The Firman P03628 is a 3,650-watt running generator built on a 208cc OHV 4-stroke engine with cast iron sleeves. This wattage class handles mid-range household loads: refrigerators, window air conditioners, well pumps, and power tools, but not simultaneous heavy-draw appliances like central AC or electric ranges. The 4,550-watt peak gives it startup headroom for motors and compressors. Gasoline fuel means easy refueling at any station, and the 5-gallon tank stretches to 14 hours at half load, reducing refueling frequency on job sites or during extended outages. The RV-ready outlet configuration and remote start make this a practical choice for both emergency backup and recreational use. | The Ford FG4050P is a 3000-watt gasoline generator built on a 208cc Ducar OHV 4-stroke engine. This wattage handles essential household appliances, power tools, and small job site equipment simultaneously. The 4050-watt peak output absorbs the startup surge of refrigerators, air compressors, and well pumps without stalling. At 108.7 pounds with an included wheel kit, the unit sits at the threshold where portability requires planning. A single person can move it short distances, but sustained transport benefits from a second set of hands or a vehicle. |
