Check price on AmazonHow we calculate it
Runtime = capacity (Wh) × 0.85 ÷ 1,050 W
For a 12-hour storm you need about 14,830 Wh (12,600 Wh of energy plus inverter losses). Running other devices at the same time? Add them in the runtime calculator.
Tips to run your sump pump longer
- A 1/2 HP sump pump needs ~2,000 W or more to start. Many portable power stations can't start it; check the surge column.
- A sump pump runs only a fraction of the time. The calculator assumes about 2 hours of runtime per day; heavy rain can mean much more.
- For long storms, consider a battery backup sump pump or a generator with a transfer switch.
Frequently asked questions
How long will a 1000Wh power station run a sump pump?
About 49 min, based on an average draw of 1,050 W and 85% inverter efficiency.
How many watts does a sump pump use?
Typically about 1,050 W while running and up to 2,150 W for a moment at start-up. Averaged over time it draws about 1,050 W.
What size power station do I need for a 12-hour storm?
