Here's the quick tradeoff view — what this model does well, and where it may not fit.
The Predator 73257 is a tri-fuel generator built around substantial output, pairing 9000 running watts with 11500 starting watts to handle demanding starts and sustained loads. With inverter capability, it is also aimed at delivering clean power while still offering the flexibility of tri-fuel operation.
That combination of high wattage and tri-fuel support makes the 73257 a practical fit for situations where both strong surge capacity and adaptable fueling matter, whether you are powering through startup spikes or keeping equipment running steadily.
As a tri-fuel inverter generator, the Predator 73257 blends fuel flexibility with clean inverter power, while its 9000 running watts provide the continuous output needed for extended use and its 11500 starting watts help cover the extra draw that occurs when motors and larger loads kick on. In real use, that higher starting figure is what helps prevent bogging down during startup moments, while the running wattage is what supports steady operation once everything is up and running.
Noise is rated at 64.5 dBA, giving a clear, measured reference point for how it will sound while operating. For runtime, it is rated for 14 hours at 25 percent load, which translates into longer stretches between refueling when you are running lighter, steady loads rather than pushing the generator near its limits.
Portability here is defined by a substantial physical footprint and mass. The Predator 73257 weighs 259.5 lbs, which is a meaningful consideration for moving it around a property or loading it for transport.
Its dimensions are 31.25 x 25 x 29.5 inches, so it occupies a clearly defined amount of floor space when stored or deployed. Those measurements help set expectations for where it can fit, whether that is in a garage corner, a shed, or a designated operating area with adequate clearance.
Est. running: 1,800W
Peak surge (single motor): 2,000W
Avoid starting multiple motor loads at the same time.
Est. running: 5,000W
Peak surge (single motor): 2,000W
Avoid starting multiple motor loads at the same time.
Est. running: 5,100W
Peak surge (single motor): 6,000W
Avoid starting multiple motor loads at the same time.
These are estimates using typical wattage assumptions. Real appliances vary. Startup surges can be 2–6× the running wattage for motor-driven loads. 240V loads require a 120/240V generator and proper connection. Use a transfer switch or interlock kit; never backfeed a panel.
Predator is recognized for its budget-friendly, high-performance generators, popular among homeowners and outdoor enthusiasts for reliable power solutions.
