Will it run? · UK figures, 230 V

How long will a power station run an electric blanket?

Short answer: Yes

For a good while. A double electric blanket draws about 80 W, so a 1,024 Wh station runs it for roughly 9 hours flat out, and for several nights if you warm the bed for an hour and switch it off.

How much power an electric blanket draws

  • Double blanket

    80 W

    Published figure

    EDF: single blankets often use 40–60 W, a double around 80 W, and king-size can use up to 250 W. EDF

  • Single blanket

    50 W

    Range 40–60 W

    Published figure

    40–60 W for a single (EDF); 50 W is the middle of the range. EDF

    250 W

    Published figure

    Up to 250 W for a king-size blanket (EDF). EDF

Hours on four power stations

Worked with BLUETTI's published formula: capacity × 0.9 × 0.85 ÷ (load + 10 W the station uses itself). Capacity and continuous output are from each maker's UK page, read on 11 October 2026. "Too much" means the station's continuous output is below what the appliance needs at once.

Anker SOLIX C1000 Gen 2: 1,024 Wh × 0.9 × 0.85 = 783 Wh usable. Double, full heat (80 W): 80 W + 10 W = 90 W. 783 ÷ 90 = 8.7 h.

Why it is the best use of battery for keeping warm

Heating a room with electricity takes 1,000–2,000 W; a blanket warms the person in bed for a twentieth of that. It also fits the government's Prepare advice for a power cut: keep warm with blankets and layered clothing, close doors to unused rooms and draw the curtains.

Most blankets heat quickly and then hold on a lower setting, so the full-heat figures are a ceiling. An hour of pre-warming on a double uses about 80 Wh, and a 1,024 Wh station has around 780 Wh of usable energy by the maker's formula.

Who needs it most

Prepare notes that older adults, babies and young children, and people with long-term health problems are the most likely to become ill if they get too cold. For a household like that, a mid-size station that keeps a blanket and the fridge-freezer going is a sensible plan.

Before you rely on it

  • Follow the blanket's own instructions on use overnight; many are designed to warm the bed and then be switched off or turned to a low setting.
  • Don't use an old or damaged blanket, and keep it flat; the station doesn't change the blanket's own safety rules.
  • King-size dual-control blankets at full heat on both sides are the 250 W case.

Which station we'd pick

Smallest on our UK list for this job

Anker SOLIX C1000 Gen 2

1,024 Wh and 2,000 W continuous: about 8.7 h at 80 W. A whole night at full heat on a double blanket, the worst case; pre-warming for an hour stretches it to several nights.

Questions

How many watts does an electric blanket use?

EDF says single blankets often use 40–60 W, a double around 80 W and a king-size up to 250 W.

Can a small power station run an electric blanket?

Yes. A 286 Wh station runs a double blanket for about 2–3 hours at full heat by our sums: enough to warm the bed before you get in, several nights running.
