Electric Blanket Wattage: How Much Electricity Does It Use?
Electric blankets are a popular way to stay warm during colder months, but many users are unsure how much electricity they actually use and whether they significantly affect their energy bills. Understanding electric blanket wattage makes it easier to estimate power consumption, calculate running costs, and choose more efficient heating options. This guide covers electric blanket wattage, energy consumption, running costs, and practical ways to reduce electricity use while staying warm.
How Many Watts Does an Electric Blanket Use?
Electric blankets are generally low-power heating devices, but their exact wattage depends on the model, size, heat setting, and usage conditions. Overall, they remain one of the most energy-efficient ways to stay warm during cold weather.
Most electric blankets typically operate between 50W and 200W, which is significantly lower than many room-heating appliances. The actual electric blanket power usage depends mainly on the blanket size, temperature setting, and how long it operates.
Wattage range by size
Electric blanket size is one of the main factors affecting electric blanket power consumption:
Blanket size | Indicative power range |
Single | Around 60–100W |
Double | Around 80–120W |
Queen | Around 100–150W |
King | Around 120–180W |
Larger blankets require more energy to heat a wider surface area, but overall consumption is still relatively low compared to other heating appliances.
* These figures are indicative only. Wattage varies by manufacturer, controller design and whether the blanket has one or two independently heated zones.
Power usage by heat setting
A higher heat setting generally increases average electric blanket wattage use. However, many electric blankets regulate temperature by cycling the heating elements on and off, so the actual average draw may be lower than the maximum wattage shown on the product label.
Seasonal usage differences
Power consumption also changes depending on outdoor temperature and usage needs:
Summer / mild nights: ~50–100W on low settings
Spring / autumn: ~100–150W on medium settings
Winter: ~150–200W on high settings
Extreme cold conditions: the blanket may briefly draw higher power during preheating.
How Much Electricity Does an Electric Blanket Use?
Electric blankets generally consume relatively little electricity compared with many other heating appliances. However, actual energy use depends on the blanket’s wattage, heat setting, and how long it is used each day.
Understanding electric blanket electricity consumption can help you estimate how much energy your blanket uses and calculate its running cost based on your local electricity rate.
Calculating Electric Blanket Energy Consumption
Electricity consumption can be estimated using this formula:
Energy consumption (kWh) = Wattage (W) × Usage time (hours) ÷ 1000
For example, if an electric blanket uses 100W and runs for 8 hours:
100W × 8 hours = 800Wh
800Wh ÷ 1000 = 0.8kWh
This means the blanket uses approximately 0.8kWh of electricity per night.
Estimated Electricity Use and Running Cost
Once you know the electricity consumption, you can estimate the running cost using your local electricity rate.
Electric blanket electricity cost is calculated using this formula:
Cost = Energy consumption (kWh) × Electricity rate (per kWh)
The following example uses an electricity usage rate of A$0.31 per kWh. Actual rates vary by state, retailer and tariff, so check your latest electricity bill for the rate that applies to your home.
Wattage | Daily Use (8h) | Daily Cost | Monthly Cost (30 days) |
50W | 0.4 kWh | ~$0.12 | ~$3.72 |
100W | 0.8 kWh | ~$0.25 | ~$7.44 |
150W | 1.2 kWh | ~$0.37 | ~$11.16 |
200W (high/preheat) | 1.6 kWh | ~$0.50 | ~$14.88 |
Real-world usage cost
In typical household use, most people operate electric blankets at medium settings for several hours per night. This keeps the electric blanket's running cost per hour low, making it one of the most affordable ways to stay warm during colder months.
Because electric blankets provide direct personal warmth instead of heating an entire room, they can be an efficient way to stay comfortable during colder months while potentially reducing the need for high-energy room heating systems.
Best Portable Power Station for an Electric Blanket When Off-Grid
Using an electric blanket off-grid requires more than just enough output power. The right portable power station needs to provide sufficient wattage to run the blanket and enough battery capacity to run the blanket for as long as needed.
Most electric blankets typically use around 50W–200W, depending on the size, heat setting, and operating conditions. When choosing a portable power station, consider both the blanket’s power consumption and how long you want to use it without access to grid electricity.
What Size Portable Power Station Do You Need for an Electric Blanket?
Choosing the right portable power station depends on the electric blanket’s wattage and how long you need to run it. Understanding what size portable power station you need can help you choose the right battery capacity without overspending or running out of power.
For example:
Electric Blanket Power | Recommended Power Station Output | Approximate Capacity for 8 Hours |
50–100 W | 150 W+ | 500–1000 Wh |
100–150 W | 200 W+ | 1000–1500 Wh |
150–200 W | 300 W+ | 1500–2000 Wh |
A larger capacity portable power station provides longer runtime and allows you to power additional devices such as phones, lights, laptops, or other camping equipment.
