| Summary | The Generac GP2500i is a 2200-watt inverter generator built for portable backup power and recreational use. At 48 pounds, it moves easily between campsites, job sites, and emergency situations. The inverter technology means laptops, phones, and sensitive tools run safely because the power output stays stable. This unit runs on gasoline and delivers 2500 starting watts, so it can handle the initial surge when motors kick on. | The Pulsar PGD40iSCO is a 4,000-watt inverter generator featuring a 145cc OHV air-cooled engine, providing 3,200 running watts and 4,000 peak watts. It operates quietly at 59 dB and offers up to 4.5 hours of runtime at half load. Equipped with CO Sentry for carbon monoxide detection, it ensures safety during operation. |
