GEN-2500-IMM1

The Firman T04073 is a 4,000-watt tri-fuel generator that runs on gasoline, propane, or natural gas. On gasoline, it delivers 5,000 starting watts and 4,000 running watts, enough to power a refrigerator, microwave, and multiple household circuits simultaneously. On propane, output drops to 3,600 running watts, and on natural gas it falls to 3,200 running watts. This fuel flexibility means users can switch between sources based on availability and cost, a significant advantage during extended outages or in remote locations where one fuel type may be scarce. The T04073 targets homeowners, RV owners, and job site operators who need reliable backup power without the commitment to a single fuel source. Its 5-gallon tank runs for 14 hours at 25% load on gasoline, translating to roughly one week of emergency backup if you run it a few hours per day. The unit includes a wheel kit, making it easier to position despite its 123.4-pound weight.

The Mi-T-M GEN-2500-IMM1 is a 2300-watt gasoline inverter generator built for users who need portable backup power without sacrificing clean output. At 57 pounds, this unit bridges the gap between true portability and enough wattage to run multiple devices simultaneously. It can power essential appliances, power tools, and sensitive electronics like laptops during camping trips, tailgating events, or residential outages. The inverter technology keeps total harmonic distortion at 3 percent, which means laptops, TVs, and phone chargers stay protected from voltage spikes. Because the fuel tank holds only 1 gallon, refueling becomes part of the operating rhythm rather than a weekend-long concern.
