Best portable power station for storm power outages, ranked by $/Wh
To run this 12-hour load profile at 85% usable AC delivery, you need a power station with at least 2,145 Wh of battery capacity, 836 W continuous AC output, and 1,336 W surge capability.
During a 12-hour severe storm power outage, running a full-size refrigerator (750 Wh over 12 hours, U.S. DOE), a 1/3 HP basement sump pump cycling for 1 cumulative hour (800 W running, 1,300 W surge, EcoFlow), a Wi-Fi router (120 Wh), and three LED bulbs (153 Wh) consumes 1,823 Wh raw energy, requiring 2,145 Wh of battery capacity and 1,336 W peak surge.
