Summary
The Predator 73255 is a gasoline generator built around a 4000 running watt output with 5000 starting watts for handling higher initial demand when equipment first kicks on. With gasoline as its fuel source, it fits shoppers who want a familiar refueling routine while still delivering substantial power for a range of household and project needs.
By pairing 4000 running watts with 5000 starting watts, the 73255 is set up to support steady operation while also accommodating brief surges, which can matter when powering items that draw extra power at startup.
Power & Runtime
As a gasoline-powered generator, the Predator 73255 combines practical refueling with a clear power profile: 4000 running watts for sustained output and 5000 starting watts for short bursts when loads first engage. That starting headroom can help reduce the need to micromanage what gets turned on first, since the generator is designed to handle higher initial demand before settling into its running capacity.
Noise is rated at 71.3 dBA, giving a concrete sense of how present the generator will sound while operating. For run time, it is rated for 15.2 hours at 50 percent load, which translates into longer stretches of operation when you are not pushing the generator to its full output.
Portability
Portability here is defined by a listed weight of 110 lbs and dimensions of 23.3 x 18.6 x 19.23 inches. That footprint makes it easier to gauge where it can be stored or staged for use, while the 110 lb weight sets expectations for the effort required to move it between storage and the work area.
With its compact rectangular dimensions, the 73255 can be planned into a garage corner, shed shelf space, or a dedicated spot near where it will be deployed, as long as the weight is taken into account when it is time to relocate it.

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.
