Q: How long will the Anker 521 PowerHouse run a space heater?

The Anker 521 PowerHouse has 256 Wh (about 196 Wh usable at the outlet, estimated). Running a space heater that draws 1500W, it lasts under an hour on a single full charge.

Will the Anker 521 PowerHouse run a space heater?

No — the space heater needs more power than this unit delivers

It draws about 1500W, but the 521 PowerHouse only outputs 200W continuously — so it won't start, or it will overload and shut off.

Because the space heater needs more continuous power than this unit can deliver, a runtime figure doesn't really apply — you'd need a higher-output station. See stronger options below, or the sizing calculator to find one that fits.
