What Size Portable Power Station Can Open a Garage Door?
Don't get your car trapped inside a heavy garage door during a blackout. See the surge wattage needed to lift a 2-car garage door.
Opening a garage door takes almost zero battery capacity (about 3 Watt-hours per lift!), but the motor needs ~1,100W of starting surge for 1 second to lift the heavy door springs. Any 800W–1,800W power station can open a garage door 100+ times on a single charge.
Pulling the manual red emergency release cord while the garage door is raised—if a spring is weak, the door can slam shut.
