Power stations for a space heater

A space heater draws 1,300 to 1,575 W, and up to 1,300 W for a moment at startup. The smallest station we chart that handles it is the Jackery HomePower 1000 Plus v2.

By the Power Station Chart team, from published appliance figures and the makers' station specs. Last reviewed October 31, 2026.

Heaters on a standard outlet draw about 1,300 to 1,575 W. A thermostat can cycle one off, which stretches these times.

What decides the size you need

A 1,024 Wh station runs a space heater for only 33 min to 40 min at 1,300 to 1,575 W. The Jackery HomePower 1000 Plus v2, with 1,800 W of AC, is the smallest that can run one. Of 81 stations, 50 handle it and 31 have too little AC output. A thermostat that cycles the heater off stretches these times. Longer heat takes real capacity. The Jackery Explorer 2000 Plus (2,042.8 Wh) lists 1.1 h to 1.3 h and the EcoFlow DELTA 3 Ultra (3,072 Wh) 1.7 h to 2 h. The EcoFlow DELTA Pro Ultra (6,144 Wh) lists 3.3 h to 4 h.

FAQ

What size power station runs a space heater?

At least 1,024 Wh with 1,800 W of AC. The Jackery HomePower 1000 Plus v2 and EcoFlow DELTA 3 Classic list 33 min to 40 min.

How long does a 3,584 Wh station run a space heater?

The Jackery HomePower 3600 Pro Max lists 1.9 h to 2.3 h, and the BLUETTI Elite 400 (3,840 Wh) lists 2.1 h to 2.5 h.

Why do 31 stations fail the check?

They have too little AC output for a heater drawing 1,300 W to 1,575 W. A heater on a standard outlet needs the output before the capacity matters.

Does a thermostat change the runtime?

Yes. When it cycles the heater off, the station gets a rest and the times listed stretch.
