How Many Watts Does an Electric Blanket Use

An electric blanket generally uses 50 to 200 watts, depending on its size, heating level, and design. When electric blankets are used in lower settings, they consume less power. On the other hand, higher heat modes draw more electricity, especially during the initial warm-up phase. Compared to space heaters, electric blankets are considered a low-wattage heating option because they warm the person directly instead of heating an entire room.

Understanding how many watts does an electric blanket use is useful when calculating winter energy costs or planning backup power during outages. Since their power draw is relatively modest, Jackery Solar Generators can run electric blankets for extended periods when properly sized. This makes solar generators practical for maintaining warmth during power interruptions, camping trips, or off-grid stays without relying on fuel-based heating sources.

Takeaways

• Most electric blankets use 50–200 watts, depending on size and heat setting.
• The energy consumption of electric blankets increases during initial heating and decreases once the temperature stabilizes.
• Running an electric blanket typically costs only a few cents per night, depending on local electricity rates.
• Jackery Solar Generators can power electric blankets and other essential appliances for long durations during outages or off-grid use.

How Many Watts Does an Electric Blanket Use?

An electric blanket typically uses 50 to 200 watts, depending on its size and heat setting. Smaller throws often stay closer to 50–100 watts, while larger full- or queen-size electric blankets can reach 150–200 watts at higher settings. Power use is usually highest during the initial warm-up phase and then decreases once the blanket reaches and maintains the selected temperature. Here's a table revealing how many watts does an electric blanket use and its energy consumption: 

Electric Blanket Watts Consumption Based on Stage

Electric blankets come with different settings to adjust the level of warmth. Here's a breakdown of power consumption based on different stages:

"0 W" in the table indicates that there is no power consumption when the electric blanket is set to "Timer/Off." This means that the blanket does not use any electricity when it's turned off or when using a timer function to automatically shut off after a certain period.

These power consumption ranges are approximate and can vary depending on the brand, model, and size of the electric blanket. Using lower settings and turning off the blanket when unnecessary can help manage energy usage more efficiently. Always refer to the manufacturer's guidelines for precise information about power consumption in different settings.

What Affects the Wattage of an Electric Blanket?

The wattage of an electric blanket can vary based on the settings and temperature conditions. Here's a general breakdown of wattages for different seasons:

Summer: During warmer months, when less heat is needed, electric blankets typically consume around 50-100 watts on low settings.

Mid Season: In spring or fall, when temperatures are moderate, the medium setting might use around 100-150 watts.

Winter: In colder winter weather, the high setting could use around 150-200 watts to provide ample warmth.

Extreme Winters: For icy conditions, the highest settings could reach 200 watts or more to generate significant heat.

Keep in mind that these are rough estimates, and actual wattages can vary based on the specific model and brand of the electric blanket. Always check the manufacturer's information for precise wattage details.

How Much Does It Cost to Run an Electric Blanket

Running an electric blanket generally costs only a few cents per night. For example, a 100-watt blanket used for 8 hours consumes 0.8 kWh (100 W × 8 h ÷ 1,000). At $0.15 per kWh, the cost to run an electric blanket is about $0.12 per night. The cost of using an electric blanket depends on its wattage, the duration of use, and your local electricity rates. Here's how you can estimate the cost:

• Calculate Daily Usage Cost: Multiply the wattage of your electric blanket by the number of hours you use it daily. Then, divide by 1000 to convert watts to kilowatts. Finally, multiply by your electricity rate (usually in cents per kilowatt-hour) to find the daily cost.

Example: (150W × 6 hours) / 1000 = 0.9 kWh

If the electricity rate is 15 cents/kWh: 0.9 kWh × 15 cents = $0.135

• Calculate Monthly and Yearly Costs: Multiply the daily cost by the number of days you use the blanket each month and then by 12 for the yearly cost.

Example: $0.135 × 30 days = $4.05 per month

• Yearly cost: $4.05 × 12 months = $48.60

We have figured out the estimates over here, and actual costs can vary. Using a programmable timer or lower settings can help save on costs.

What Size Power Station Do I Need For the Electric Blanket When Off-Grid

For most electric blankets, a small to mid-size portable power station is sufficient, since they typically draw only 50–200 watts. The key factor is how many hours you plan to run it. For example, a 100-watt blanket running for 8 hours uses 800 Wh (100 W × 8 h). You’ll need a power station with enough battery capacity (in watt-hours) to cover that demand, plus extra if you’re powering other devices.

To get a more accurate estimate based on your specific electric blanket and usage time, you can use the Running Time Calculator on the Jackery Buying Guide page. By entering your blanket’s wattage and selecting a Jackery model, you can see realistic runtime estimates instead of relying on rough assumptions.

Like Scott Simpson, many homeowners in storm-prone regions don’t wait for the next outage to rethink their power strategy. Living in rural Wisconsin, he built a system that keeps critical appliances running when the grid fails, including lights, refrigerator, well pump, water heater, furnace, and WiFi. With his Jackery unit connected to his home’s inlet, he can switch over quickly and keep essential circuits powered without rewiring his setup.
