How long will a 1000Wh power station run a Desktop Computer?

A 1000Wh power station runs a desktop computer (about 200W) for roughly 4.3 h, after accounting for typical inverter and battery losses (~85% usable).

How long will a 2000Wh power station run a Desktop Computer?

A 2000Wh power station runs a desktop computer (about 200W) for roughly 8.5 h, after accounting for typical inverter and battery losses (~85% usable).

How is Desktop Computer 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 Desktop Computer draws about 200W.

How long will a portable power station run a Desktop Computer?

A Desktop Computer draws about 200W. 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	1.3 h
500 Wh	2.1 h
1,000 Wh	4.3 h
1,500 Wh	6.4 h
2,000 Wh	8.5 h
3,000 Wh	13 h
5,000 Wh	21 h

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