Runs a well pump ≈ 3.1 h
Check price on AmazonHow we calculate it
Runtime = capacity (Wh) × 0.85 ÷ 1,000 W
For a day of water (about 2 hours of pumping) you need about 2,360 Wh (2,000 Wh of energy plus inverter losses). Running other devices at the same time? Add them in the runtime calculator.
Tips to run your well pump longer
- The start-up surge is the hard part: a 1/2 HP pump can briefly draw 3,000 W or more. If the station trips at start-up, it is undersized for your pump.
- A well pump runs only when the pressure tank refills, often 1–3 hours per day in total. Save water to reduce pump cycles.
- Fill buckets and bathtubs before a forecast storm so you only need to run the pump occasionally.
Frequently asked questions
How long will a 1000Wh power station run a well pump?
About 51 min, based on an average draw of 1,000 W and 85% inverter efficiency.
How many watts does a well pump use?
Typically about 1,000 W while running and up to 3,000 W for a moment at start-up. Averaged over time it draws about 1,000 W.
What size power station do I need for a day of water (about 2 hours of pumping)?
At least 2,360 Wh. The smallest model in our comparison that covers it is the EcoFlow DELTA Pro (3,600 Wh, about 3.1 h).
