An electric blanket is the smartest way to stay warm during a winter outage in an apartment — it sips power where a space heater guzzles it. Here is exactly how long a power station runs one.
The short answer
Electric blankets draw only 50–100 W, so almost any power station runs one for hours. A 1 kWh unit keeps a blanket going all night (8–17 hours). Compared with a 1500 W space heater, a blanket gives you 20× the runtime — it is the renter’s best outage-heating move.
Electric blanket runtime by capacity
| Setting | Watts | On 500Wh | On 1000Wh |
|---|---|---|---|
| Low | ~50 W | ~8.5 hrs | ~17 hrs |
| High | ~100 W | ~4.3 hrs | ~8.5 hrs |
| Heated throw | ~120 W | ~3.5 hrs | ~7 hrs |
