Summary
The Ford FG6250P is a 5,250-watt gasoline generator built around a 420cc OHV engine that delivers enough continuous power to run a refrigerator, sump pump, lights, and several power tools simultaneously. This wattage tier covers whole-house emergency backup for modest homes or active job site power where circular saws, drills, and compressors cycle throughout the day. A 6.6-gallon tank stretches to 11 hours at 50% load, eliminating mid-shift refueling during typical use. At 167.6 pounds with a wheel kit included, this unit is heavy and demands dedicated storage and transport planning.
The Generac GP5500E is a 5,500 watt gasoline generator built to power whole house essentials during outages or on job sites. Its 6,875 starting watts handle motor driven appliances like well pumps and air conditioners that demand heavy inrush current. For homeowners and contractors who want reliable backup without crossing into stationary generator territory, the GP5500E delivers meaningful output with the refueling simplicity of gasoline.
