Electric blanket / heated pad — Wh honesty

Often workable on mid stations overnight — low continuous draw vs room heaters. Blanket wins on Wh over space heaters; note CPAP combo load. Cross-link: CPAP overnight · apartment blackouts · storm kit.

Often workable overnight — blanket beats space heater

  • Low continuous W. Many electric blankets / heated mattress pads pull ~50–150 W (sometimes cycling lower on thermostat) — not the 750–1,500 W resistive trap of a space heater.
  • Blanket wins on Wh. Warming the bed beats heating the room. A mid ~1 kWh station can often cover an overnight blanket (estimates: 8 h at 80 W ≈ ~0.75 kWh before inverter loss) while a space heater empties the same box in under an hour.
  • CPAP combo: if you also run a CPAP, add both loads — typical CPAP 30–60 W plus blanket 50–100 W is still mid-station friendly for one night when measured. Full curves on CPAP overnight; don’t stack a heater on top.
  • Apartment / lease: fume-free bed warmth is the neighbour-safe path — same story as apartment blackouts. Skip open-flame and skip whole-room resistive heat on battery.
  • Storm kit fit: pair blanket + lights + phone/router, not dryer/AC/heater. See storm / blackout kit and heatwave fan vs AC for the opposite season’s Wh-cheap comfort.

Overnight Wh estimates

Hours ≈ (rated Wh × 0.85) ÷ blanket watts.

Low ~60 W

Mid overnight

1 kWh ≈ ~12–14 h (est.) — often clear with headroom

Typical ~100 W

Mid maybe night

1 kWh ≈ ~8–9 h; 2 kWh ≈ ~16–17 h (estimates)

Vs space heater

Blanket wins

Same Wh: hours of bed warmth vs minutes of room heat — heater honesty

Comparison: blanket-duty honesty

Filter by overnight fit for electric blanket / heated pad.

Model Wh · continuous AC Overnight fit Vs heater / CPAP honesty Approx. USD
EcoFlow RIVER 3 Plus Short 286 Wh · 600 W Few hours at ~80–100 W — pre-warm then unplug often wiser. Still beats trying a space heater on this box. ~$180–300
Anker SOLIX C300 288 Wh · 300 W Similar short window — continuous W clears; Wh is the gate. Save for phone/CPAP if medical priority. ~$200–280
Jackery Explorer 1000 v2 Overnight 1,070 Wh · 1,500 W Strong overnight chance at typical blanket watts (estimates). Blanket wins vs heater by a wide margin. ~$499–589
BLUETTI Elite 100 V2 1,024 Wh · 1,800 W Similar ~1 kWh overnight math — measure pad watts once. Good mid path for bed warmth without room heat waste. ~$380–500
Anker SOLIX C1000 Expand 1,056 Wh → 2,112 Wh · 1,800 W Expand packs help multi-night or CPAP + blanket stacks. Add loads from CPAP overnight before promising both. ~$400–600
EcoFlow DELTA 3 Plus 1,024 Wh · 1,800 W class Solid overnight + light extras (phone, LED, router). Still skip space heater — see apartment priorities. ~$600–900+
BLUETTI AC200L Best headroom 2,048 Wh · 2,400 W class Best Wh in this set for blanket + CPAP + storm extras. Pair with storm kit — still not a heater budget. ~$800–1,100
