| Summary | The Generac GP9500ETF is a 9,500-watt tri-fuel generator built for whole-house backup and job site power. Its ability to run on gasoline, propane, or natural gas means users gain real fuel flexibility when one source becomes scarce during extended outages. The 12,500 starting watts provide enough surge capacity to handle motor-driven loads like well pumps and air handler fans without tripping breakers. This is a stationary workhorse, not a portable unit. | The Powermate PM4500 is a 4500-watt portable generator featuring COsense® Technology for carbon monoxide protection, a Generac® 224CC OHV Engine, and a 19-hour run time at 25% load. |
