Lower load than room heating
An electric blanket warms a person directly, so it can use far less energy than trying to heat a room.
Specialized runtime calculator
Electric Blanket Power Station Runtime Calculator
Estimate electric blanket runtime, full nights, and required power station capacity.
Electric blankets usually use much less power than space heaters, especially when controlled by a thermostat or heat setting.

Electric Blanket Power Station Runtime Calculator FAQ
Is an electric blanket better than a space heater for battery backup?
For personal warmth, it usually uses much less power. It does not heat a room.
Should I use rated watts?
Use the blanket or controller label. Actual draw may be lower depending on heat setting.
Accuracy notes
This calculator estimates electrical runtime and sizing. Actual results can change with device model, load variation, battery age, temperature, inverter idle draw, charge level, reserve settings, and manufacturer limits. Verify safety-critical loads with the device and power station documentation.
