| Summary | The Cummins Onan P2500i is a 2200-watt inverter generator built for users who need portable power without sacrificing runtime or noise control. At 48 pounds and measuring 19.8 by 10.5 by 18.3 inches, this unit bridges the gap between true portability and practical capacity. It can run a microwave, small refrigerator, or circular saw continuously, making it suitable for camping trips, job sites, tailgating, and emergency backup. The 1-gallon fuel tank delivers 10 hours at 25 percent load and 8 hours at 50 percent load, meaning most users refuel once per day rather than multiple times.
The inverter topology produces clean power with less than 3 percent THD, which protects laptops, phone chargers, and sensitive electronics from voltage spikes. Cummins backs this unit with a 3-year warranty, longer than the 2.4-year average for comparable inverter generators. The 52 dBA noise level sits between a normal conversation and light traffic, allowing operation in noise-restricted campgrounds and residential neighborhoods without drawing complaints. | The NorthStar e14000s is a commercial-grade EFI portable generator with electric start, delivering 14,000 surge watts and 12,000 rated watts. It features a NorthStar e670 OHV EFI engine, Quiet Armor Technology for reduced noise, and a heavy-duty steel exoskeleton for durability. |
