Best portable power station for work sites and power tools, ranked by $/Wh

To run this 8-hour load profile at 85% usable AC delivery, you need a power station with at least 3,402 Wh of battery capacity, 1,869 W continuous AC output, and 2,969 W surge capability.

Jobsite and utility loads require high continuous and surge inverter output to start induction motors. A 1/2 HP motor load (1,050 W running, 2,150 W starting surge, EcoFlow Sump Pump Wattage Guide) plus high-draw equipment (785 W for 2 hours) and four work lights over an 8-hour shift consumes 2,892 Wh (3,402 Wh rated capacity at 85% usable AC fraction) and 3,021 W peak surge.
