What power station runs an electric heated blanket all night?

Updated 2026-11-08 · Pick: BLUETTI Elite 30 V2: $275.50 through this link, discount applied in BLUETTI's cart (tested on this model 2026-11-13); Walmart $279.99, bluettipower.com without the link $289.99, checked 2026-11-13: https://dealectric.com/go/bluetti-elite-30-v2

A heated blanket is one of the easiest things to run from a battery: a 12 V blanket draws about 35–60 W on high and as little as 12 W on low, and a 120 V queen about 80–120 W on high and 15–70 W on low. What decides the battery size is the setting, the hours and whether you go through the inverter.

How many watt-hours a night takes

Multiply the blanket's average draw by the hours, then add the station's own draw. A 12 V blanket on low at about 12 W for 10 hours is 120 Wh; on high at 50 W it is 500 Wh. A 120 V queen on low at 20–45 W is 200–450 Wh, plus 45–190 Wh for an inverter drawing 4.5–19 W for those 10 hours. That is why a 12 V blanket from the car port goes much further on a small station: no inverter running all night. (All arithmetic from the wattages above; the only metered 120 V figures we found are a retailer's 15–20 W on low and 50–70 W on high.)

Low-load shut-off

Some stations switch AC or DC off when the load is small for a while (BLUETTI calls it ECO mode, adjustable in its app). A blanket that cycles on its thermostat can look like no load, so turn ECO off for overnight use. Many 120 V blankets also switch themselves off after about 10 hours (Sunbeam).

Safety

Sunbeam's manuals say to plug the blanket in directly, with no extension cords or power strips; plug it straight into the station's outlet. Keep the station off the bed and away from the blanket's folds.
