| Summary | The Generac GP3300i is a 2,500-watt inverter generator built for users who need portable, clean power without the weight penalty. At 59.5 lbs, it moves easily between campsites, tailgates, and home backup scenarios. The 3,300-watt starting capacity handles motor-driven equipment, while sub-3% THD protects laptops and phones from voltage spikes. | The Predator 73422 is a gasoline-powered generator rated for 2000 running watts with 2500 starting watts. That combination sets it up to handle steady electrical loads while also giving extra headroom for devices that draw more power when they first switch on. |
