| Summary | The Honda EB6500X is a 5500-watt gasoline generator built for job sites and extended outages. Its 6500-watt peak output handles large equipment startups, while a 6.2-gallon tank delivers 9.8 hours of runtime at half load. The recoil start and included wheel kit make it mobile, though at 215.8 lbs it requires planning for transport. | The NorthStar e18000s is a commercial-grade EFI portable generator with electric start, delivering 18,000 surge watts and 15,000 rated watts. It features a NorthStar e825 OHV EFI engine, Quiet Armor Technology for reduced noise, and a heavy-duty steel exoskeleton for durability. |
