Home Power Facts Can a portable power station run a space heater?
Yes, 13 of the 15 power stations we track can run a space heater; the smallest that can is the DJI Power 1000. Expect about 0.5 h (DJI Power 1000) to 1.9 h (Anker SOLIX F3800) on a full charge.

Runtime = usable capacity ÷ average draw. "(est.)" means no independent capacity test exists, so we assume 80% of rated capacity reaches the AC outlets. See the methodology. "Check price" links may be affiliate links.
What size do you need?
What size power station do I need for a space heater?
Look for at least 1,500 W of continuous AC output and 1,500 W of surge. For capacity, a space heater averages about 1,500 W, so 8 hours needs roughly 15,000 Wh of rated capacity and 24 hours roughly 45,000 Wh, assuming 80% of rated capacity reaches the outlets.
How long will a 1,000 Wh power station run a space heater?
About 0.5 h, if its inverter can handle the 1,500 W startup surge: roughly 800 Wh reaches the outlets, divided by an average draw of 1,500 W.
Which power station can run a space heater for a full day?
None of the 15 models we track runs a space heater for 24 hours on one charge. Plan to recharge (solar or grid) during the day, or add an expansion battery.
What a space heater draws
| Running watts | 1,500 W[source]CWLP chart: 'Room space heater (1500 watt)' at 1.5 kWh/hr. Champion lists 750-1,500 W (the low end is a heater's low setting). |
|---|---|
| Startup (surge) watts | 1,500 W[source]Champion lists no extra starting watts for space heaters; surge = running. |
| Average draw used above | 1500 W |
| Voltage | 120 V |
