How long will a 1000Wh power station run a Refrigerator (Full Size)?

A 1000Wh power station runs a refrigerator (full size) for roughly 14 h in real use, because compressor-based appliances only run about 40% of the time. At a continuous 150W draw it would be about 5.7 h.

How long will a 2000Wh power station run a Refrigerator (Full Size)?

A 2000Wh power station runs a refrigerator (full size) for roughly 1.2 days in real use, because compressor-based appliances only run about 40% of the time. At a continuous 150W draw it would be about 11 h.

How is Refrigerator (Full Size) 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 Refrigerator (Full Size) draws about 150W, 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 Refrigerator (Full Size)?

A Refrigerator (Full Size) draws about 150W. As a compressor-based appliance it typically runs only about 40% of the time, so its real average draw is closer to 60W. The table below shows both the continuous figure and the more realistic duty-cycle runtime.

Power Station	Continuous	Real (~40% duty)
300 Wh	1.7 h	4.3 h
500 Wh	2.8 h	7.1 h
1,000 Wh	5.7 h	14 h
1,500 Wh	8.5 h	21 h
2,000 Wh	11 h	1.2 days
3,000 Wh	17 h	1.8 days
5,000 Wh	1.2 days	3.0 days

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