How long will a 1000Wh power station run a Space Heater (Small)?

A 1000Wh power station runs a space heater (small) (about 1000W) for roughly 0.8 h, after accounting for typical inverter and battery losses (~85% usable).

How long will a 2000Wh power station run a Space Heater (Small)?

A 2000Wh power station runs a space heater (small) (about 1000W) for roughly 1.7 h, after accounting for typical inverter and battery losses (~85% usable).

How is Space Heater (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 Space Heater (Small) draws about 1000W.

How long will a portable power station run a Space Heater (Small)?

A Space Heater (Small) draws about 1000W. 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	0.3 h
500 Wh	0.4 h
1,000 Wh	0.8 h
1,500 Wh	1.3 h
2,000 Wh	1.7 h
3,000 Wh	2.5 h
5,000 Wh	4.3 h

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