| Summary | The Generac iQ3600DF is a 2,800-watt dual-fuel inverter generator that handles mid-range loads like essential home circuits during outages, multiple appliances at a campsite, or a mix of power tools on a job site. Gasoline delivers 2,800 running watts with 3,600 starting watts; propane runs at 2,500 watts with 3,200 starting watts. The dual-fuel design lets users choose based on fuel availability and storage preferences. Inverter technology keeps THD below 3 percent, protecting laptops and TVs from voltage spikes. Electric start with an included battery eliminates pull-cord friction. The 107-pound weight and compact footprint make it semi-portable but manageable for truck beds and garage storage. | 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. |
