Can a 1,000 Wh portable power station run a 1,500 W space heater, and for how long? (2026)
Updated 2026-11-04 · Pick: Anker SOLIX C1000 Gen 2 (1,024 Wh), $529.99 on Amazon (checked 2026-11-12), buy on Amazon: https://www.amazon.com/dp/B0FN7MSY4L?tag=dealectric-20
Short answer. Yes, but only for about half an hour: a 1,000 Wh power station runs a 1,500 W space heater for roughly 33 minutes flat out, a little longer if its thermostat cycles. The Anker SOLIX C1000 Gen 2 ($529.99 on Amazon (checked 2026-11-12); buy on Amazon: https://www.amazon.com/dp/B0FN7MSY4L?tag=dealectric-20) has the 2,000 W output to run one with headroom. For a night, an electric blanket at about 100 W lasts 8–10 hours from the same charge.
What to know: these are calculations, not tests; no reviewer has timed a 1,500 W heater on a 1,000 Wh unit. The nearest measurements are on a 1.5 kWh Jackery: just under 90 minutes with a thermostat heater in an office with the window open, and 62 minutes at about 1,160 W. On its low setting (about 750 W) a 1,000 Wh unit gives about an hour. CPSC says to plug a heater directly into an outlet, never a power strip; on a station, use its own AC socket.

The arithmetic
A heater on high draws its full 1,500 W while the element is on. A 1,024 Wh unit delivers about 870–910 Wh to an AC load (907 Wh measured from the C1000 Gen 2), so 900 Wh ÷ 1,500 W is about 36 minutes; we round down to "about 35" because the station's own draw and heat losses take a little more. A thermostat that switches the element off when the room warms stretches that: in GeekDad's test with the window wide open the heater ran just under 90 minutes on a Jackery Explorer 1500 that would last about 59 minutes at constant full draw. Expert Reviews ran a 2 kW heater on its first level (about 1.16 kW) for 62 minutes from a 1.5 kWh unit. Anker suggests a station rated 20–30 % above the heater, which is why a 1,500 W heater needs 1,800–2,000 W of continuous output.
Staying warm through a night
Heat the person, not the room: an electric throw draws about 50–80 W and a full or queen blanket about 80–200 W (Anker's figures), so 100 W gives 8–10 hours from a 1,000 Wh unit; a 12 V heated blanket at 50 W on the car port gives about 17 hours. A small ceramic heater on 500 W gives about 1.7 hours. A heater stays the tool for a short warm-up.
Safety
CPSC counts an average of 1,600 fires, 70 deaths and 150 injuries a year from portable heaters (2020–2022) and says to plug them directly into a wall outlet, never into an extension cord or power strip. With a power station, that means the station's own AC outlet, the heater on a hard, level floor, and three feet of clearance.
