| Summary | 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. | The Cat RP3600 is a 3600-watt gasoline generator built for job sites and RV camping. Its 4500-watt peak output handles startup surges for power tools and air conditioners, while the 3600-watt running capacity sustains multiple household circuits or a single large appliance continuously. |
