| Summary | The ECHO EG-3500 is a 2,800-watt gasoline generator built around a 212 cc OHV 4-stroke engine. At this wattage, it handles essential household loads like refrigerators, sump pumps, and power tools, but cannot run a central air conditioner or multiple high-demand appliances simultaneously. The 3,500-watt peak output gives it a brief surge capacity for motor startup, which matters when powering devices with inrush current demands. ECHO positions this unit for homeowners managing short outages, campers needing overnight power, and contractors powering hand tools on job sites where grid access is unavailable. | The PREDATOR® 1800 Watt Portable Generator is a compact and lightweight gas-powered generator designed for low-power applications, featuring CO SECURE® carbon monoxide shutdown for enhanced safety. |
