How many watts does an electric blanket use?
An electric blanket uses about 150 watts when it is running (most models draw 100–200 W). Each hour it runs uses 0.15 kWh, which costs about 3¢ at the U.S. average price of 18.16 ¢/kWh. Running 8 hours a day, that comes to about 36 kWh, or $6.54 a month.
Watts, amps, and kWh for an electric blanket
| Measure | Value |
|---|---|
| Rated wattage range | 100–200 W |
| Average draw used in our math | 150 W |
| Amps at 120 V | 0.8–1.7 A (1.3 A at the average draw) |
| kWh per hour | 0.15 kWh |
| kWh per day at 8 hours/day | 1.20 kWh |
| kWh per month | 36.0 kWh |
| Cost per month at the U.S. average (18.16 ¢/kWh) | $6.54 |
The math is kWh = watts × hours ÷ 1000 and amps = watts ÷ volts. A standard 120 V household circuit on a 15 A breaker carries about 1,800 W. For the dollars in your state, open cost to run an electric blanket in Texas and switch states from there.
