Recommended size: 5,000–7,500W
A 5,000–7,500W portable generator handles most construction power tools. A circular saw (2,400W starting), air compressor (4,500W starting), and electric drill (900W starting) all run comfortably on a 7,500W unit. For basic tool use without an air compressor, 5,000W is sufficient.
Affordable dual fuel option with MX2 power boost technology. Runs on gas or propane for flexible fuel options during outages.
Jobsite generators need raw power and durability more than quiet operation or fuel efficiency. An air compressor alone can pull 4,500W on startup, so if that is part of your toolkit, a 7,500W generator is the minimum. Running a circular saw and drill simultaneously draws about 3,300W starting, which a 5,000W generator handles with headroom. The DuroMax XP5500EH is the budget pick at this tier. For running multiple heavy tools at once or adding lighting rigs, the Westinghouse WGen7500DFc and Generac GP7500E deliver the wattage and fuel flexibility contractors need for full-day operation.
