An electric blanket is one of the most efficient ways to stay warm on battery power. It heats you instead of the whole room, so it uses a small fraction of what a space heater does. Even a compact 300 Wh station can run one for several hours, and a 1 kWh station can run one all night, several nights in a row.

How many watts does an electric blanket use?

Most electric blankets and heated mattress pads are rated around 50–200 W, depending on size and setting. A queen blanket is often about 100 W at full power. Once the bed is warm, the thermostat cycles the heat on and off, so the average draw falls, often to around half.

Throw or single: about 50–100 W
Queen: about 100–150 W
King, dual control: about 150–200 W with both sides on

Your blanket’s label lists its rated watts. A cheap plug-in watt meter can measure the real average over a night.

Runtime by power station

This table assumes a queen blanket rated at 100 W, cycling about half the time (about 50 W on average).

Electric blanket (queen): 100 W running, ~50% duty cycle. Current models; “Borderline” means within 10% of the station’s rating.

Using a lower setting, or warming the bed for 30 minutes and then switching to low, stretches these times further.

Tips for a warm night on battery

Preheat, then turn it down. High setting while you get into bed, then low or a timer.
Layer up. A regular comforter on top traps the heat, so the blanket cycles less.
Use AC only for the blanket. Charge phones from USB ports, which waste less energy than the inverter.
Turn on the station’s AC output only when you need it. An idle inverter still uses some power.
Charging in the cold: most LiFePO4 stations won’t charge below freezing. Keep the station in the tent, car or warmest room.

Electric blanket vs space heater vs furnace

Heat source	Typical draw	1 kWh station lasts
Electric blanket (queen)	~50 W average	about 17 hours
Gas furnace blower	~250 W average	about 3.5 hours
Space heater on high	1,500 W	about 35 minutes (only on models with 1,500 W+ output)

Estimates use 85% usable capacity. Read more in can a power station run a gas furnace and can a power station run a space heater.

Safety

Follow the blanket maker’s instructions: don’t fold or bunch it while it’s on, and replace any blanket with damaged wiring. Power stations are safe indoors and in a tent because they produce no fumes; keep yours on a hard surface, not buried in bedding.
