How long will a 1000Wh power station run a Water Pump (Small)?

A 1000Wh power station runs a water pump (small) for roughly 8.5 h in real use, because compressor-based appliances only run about 40% of the time. At a continuous 250W draw it would be about 3.4 h.

How long will a 2000Wh power station run a Water Pump (Small)?

A 2000Wh power station runs a water pump (small) for roughly 17 h in real use, because compressor-based appliances only run about 40% of the time. At a continuous 250W draw it would be about 6.8 h.

How is Water Pump (Small) runtime calculated?

Runtime = usable battery energy ÷ power draw. Usable energy is about 85% of the rated capacity after depth-of-discharge and inverter losses. A Water Pump (Small) draws about 250W, but as a compressor load it only runs ~40% of the time, so real-world runtime is longer than the continuous figure.

How long will a portable power station run a Water Pump (Small)?

A Water Pump (Small) draws about 250W. As a compressor-based appliance it typically runs only about 40% of the time, so its real average draw is closer to 100W. The table below shows both the continuous figure and the more realistic duty-cycle runtime.

Power Station	Continuous	Real (~40% duty)
300 Wh	1.0 h	2.5 h
500 Wh	1.7 h	4.3 h
1,000 Wh	3.4 h	8.5 h
1,500 Wh	5.1 h	13 h
2,000 Wh	6.8 h	17 h
3,000 Wh	10 h	1.1 days
5,000 Wh	17 h	1.8 days

Estimates use ~85% usable capacity (depth of discharge + inverter losses). Actual runtime varies with temperature, load variation, and device efficiency.
