| Summary | The Genmax GM10500iETC is an 8500-watt tri-fuel inverter generator that runs on gasoline, propane, or natural gas. This wattage handles mid-to-large loads like air conditioning units, power tools, and multiple household appliances simultaneously. The tri-fuel flexibility means users can switch fuels based on availability and cost, a significant advantage for both emergency backup and remote work sites. | The Westinghouse iGen2800DFc is a 2200-watt dual-fuel inverter generator that runs on gasoline or propane. Its lightweight 45.4-pound frame and 52 dBA noise level make it suitable for RV camping, backup power, and job sites where portability and quiet operation matter. |
