How Many Watts Does An Electric Blanket Use?
An electric blanket uses 200 watts running, 0 watts surge, with 50% duty cycle because it cycles on and off to maintain temperature.
Quick Answer Box:
- Running Watts: 200W
- Starting / Surge Watts: 0W
- Running Amps: 1.67A @ 120V
- Duty Cycle: 50% – cycles 15 minutes on, 15 off at medium setting
- Daily kWh for 8 hours at 50% duty: 0.8 kWh
Low setting uses 100W, high uses 200W continuous when heating.
How Much Does It Cost to Run an Electric Blanket?
Formula: Watts x duty x hours / 1000 x $/kWh = cost
At $0.15/kWh, 8 hours per night at medium 50% duty:
| Usage | kWh per Day | Cost per Day @ $0.15 | Cost per Month @ $0.15 | Cost per Month @ $0.30 |
|---|---|---|---|---|
| 8 hrs/night low 100W @ 50% | 0.4 kWh | $0.06 | $1.80 | $3.60 |
| 8 hrs/night med 200W @ 50% | 0.8 kWh | $0.12 | $3.60 | $7.20 |
| 8 hrs/night high 200W @ 100% | 1.6 kWh | $0.24 | $7.20 | $14.40 |
At California $0.45/kWh, 8 hours at 50% duty costs $10.80 per month.
Can a Portable Power Station Run an Electric Blanket?
Yes, but it needs at least 200W continuous. MARBERO Portable Power Station 88Wh at 80W fails – not enough. 21 stations pass.
Runtime at 200W continuous, 50% duty means elapsed time is 2x continuous runtime. Below is continuous runtime – double it for real night time at 50% duty:
Small – Short warmup:
- Azocek DC 18V to AC 110V Portable Power Station – 220wh, 220w – 0.9hrs continuous, 1.8hrs real at 50%
- Jackery Explorer 300 – 293wh, 300w – 1.2hrs continuous, 2.4hrs real
- BLUETTI AC50B – 448wh, 700w – 1.9hrs continuous, 3.8hrs real

- BLUETTI AC70 – 768wh, 1000w – 3.3hrs continuous, 6.6hrs real
Medium – One full night:
- Anker SOLIX C1000 – 1056wh, 1800w – 4.5hrs continuous, 9hrs real
- Anker SOLIX C1000 Gen 2 – 1056wh, 2000w – 4.5hrs continuous, 9hrs real

- BLUETTI Elite 200 V2 – 2073.6wh, 2200w – 8.8hrs continuous, 17.6hrs real
- Dabbsson 2150Wh Portable Power Station – 2150wh, 2400w – 9.1hrs continuous, 18.2hrs real
Large:
- OUPES Exodus 2400 – 2232wh, 2400w – 9.5hrs continuous, 19hrs real
- BLUETTI Elite 300 – 3014wh, 2400w – 12.8hrs continuous, 25.6hrs real
- Anker SOLIX F3000 – 3072wh, 3600w – 13.1hrs continuous, 26.2hrs real

- Westinghouse 14500 Peak Watt Tri-Fuel Home Backup Portable Generator – 35000wh, 11500w – 148.8hrs continuous, 297.6hrs real
What Size Generator Do You Need for an Electric Blanket?
Minimum 220W continuous. The smallest that passes is Azocek DC 18V to AC 110V Portable Power Station at 220W for 0.9 hours continuous.
Recommendation: 1000W – 2000W. Electric blankets draw high watts. For one full 8-hour night at 50% duty you need 941Wh usable – that is 200W x 8 hours x 50% / 0.85. Anker SOLIX C1000 Gen 2 at 1056Wh gives 9 hours real time, which is the minimum for a full night at medium.
2 Tips to Save Power on an Electric Blanket Only
1. Preheat for 30 minutes then turn off. An electric blanket at 200W for 30 minutes uses 100Wh to warm the bed. Leaving it on all night at 50% duty for 8 hours uses 800Wh. Preheat with an EcoFlow River 3 Plus EB600 for 30 minutes at 200W – uses 100Wh – then turn it off and sleep under the retained heat. You save 700Wh and the EB600 goes from 4.8 hours real to 8 nights of preheat.
2. Use low setting with a regular blanket on top. High setting is 200W at 100% duty, low is 100W at 50% duty – actual average 50W vs 200W. Low setting with a comforter on top keeps the same bed temperature as high setting alone. On a Jackery Explorer 300, low setting gives 4.8 hours real vs 2.4 hours at medium. This only works for electric blankets with adjustable heat – not for 12V heated blankets.
FAQ
How long will an electric blanket run on Jackery Explorer 300?
1.2 hours continuous at 200W, 2.4 hours real at 50% duty. At low 100W 50% duty, 4.8 hours real. The Jackery 300 at 293Wh has 249Wh usable – not enough for a full 8-hour night at medium. You need at least Anker C1000 for 9 hours real.
Can a 88Wh power station run an electric blanket?
No. MARBERO Portable Power Station 88Wh at 80W continuous cannot run a 200W electric blanket. It fails continuous by 120W. The minimum is 220W continuous like Azocek 220Wh.
