How long will a 1000Wh power station run a Oxygen Concentrator (Portable)?

A 1000Wh power station runs a oxygen concentrator (portable) (about 120W) for roughly 7.1 h, after accounting for typical inverter and battery losses (~85% usable).

How long will a 2000Wh power station run a Oxygen Concentrator (Portable)?

A 2000Wh power station runs a oxygen concentrator (portable) (about 120W) for roughly 14 h, after accounting for typical inverter and battery losses (~85% usable).

How is Oxygen Concentrator (Portable) 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 Oxygen Concentrator (Portable) draws about 120W.

How long will a portable power station run a Oxygen Concentrator (Portable)?

A Oxygen Concentrator (Portable) draws about 120W. The table below shows how long common power station sizes will run it, after accounting for real-world inverter and battery losses (about 85% of rated capacity is usable).

Power Station	Continuous
300 Wh	2.1 h
500 Wh	3.5 h
1,000 Wh	7.1 h
1,500 Wh	11 h
2,000 Wh	14 h
3,000 Wh	21 h
5,000 Wh	1.5 days

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