How long will a 1000Wh power station run a Portable AC (8,000 BTU)?

A 1000Wh power station runs a portable ac (8,000 btu) for roughly 2.4 h in real use, because compressor-based appliances only run about 40% of the time. At a continuous 900W draw it would be about 0.9 h.

How long will a 2000Wh power station run a Portable AC (8,000 BTU)?

A 2000Wh power station runs a portable ac (8,000 btu) for roughly 4.7 h in real use, because compressor-based appliances only run about 40% of the time. At a continuous 900W draw it would be about 1.9 h.

How is Portable AC (8,000 BTU) 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 Portable AC (8,000 BTU) draws about 900W, 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 Portable AC (8,000 BTU)?

A Portable AC (8,000 BTU) draws about 900W. As a compressor-based appliance it typically runs only about 40% of the time, so its real average draw is closer to 360W. The table below shows both the continuous figure and the more realistic duty-cycle runtime.

Power Station	Continuous	Real (~40% duty)
300 Wh	0.3 h	0.7 h
500 Wh	0.5 h	1.2 h
1,000 Wh	0.9 h	2.4 h
1,500 Wh	1.4 h	3.5 h
2,000 Wh	1.9 h	4.7 h
3,000 Wh	2.8 h	7.1 h
5,000 Wh	4.7 h	12 h

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