Can a Power Station Run a Space Heater?

By Hicham M. · Updated October 11, 2026 · How we calculate

It can, but not for long. Plug-in space heaters usually top out at 1,500 W, and even with the thermostat cycling it about half the time (750 W average) a 1,000 Wh power station lasts about 1.1 hours. On high, nonstop, it’s closer to 34 min.

No plug-in heater gets more warmth out of each watt than another. DOE notes that electric resistance heating is 100% efficient: every watt becomes heat, whatever the box looks like. On a battery, it makes more sense to put the heat right next to your body.

Heater vs blanket on the same battery

Nonstop runtimes with 85% inverter efficiency. Heater ratings are from Lasko and Vornado; the mattress pad figure is from a retailer listing for a Sunbeam queen pad.

Safety first

Space heaters are involved in about a third of home heating fires but nearly nine in ten heating-fire deaths, according to NFPA’s research for 2016–2020. The CPSC’s safety advice applies on a power station too: plug the heater in directly (never through an extension cord or power strip), keep it at least 3 feet from anything that can burn, and never leave it running while you sleep.

Staying warm without draining it

Questions

What is the best way to stay warm with a power station?
Power low-watt heat close to your body: an electric blanket, heated mattress pad or heated clothing. They use a small fraction of a space heater’s power.
Is an “energy efficient” space heater worth it on a battery?
Not for runtime. DOE says all electric resistance heaters turn 100% of their electricity into heat, so a 1,500 W heater drains the same battery in the same time whatever its design.
