How Long Will a Power Station Run an Electric Blanket?
Verified October 2026 Manufacturer + DOE typical ratings. Methodology
Heated Blanket wattage by type
| Type | Rated watts | How it draws |
|---|---|---|
| Heated throw | 50-100W | Often no thermostat |
| Twin blanket | ~60W | Cycles on thermostat |
| Full / double blanket | ~100W | Cycles on thermostat |
| Queen (dual control) | ~150W | Two zones, cycles |
| 12V car / camping blanket | ~50W (about 4A @12V) | Runs off DC port |
Here's the comparison that matters in a winter outage: a 1,500W space heater empties a 1,000Wh power station in about 35 minutes. An electric blanket on the same battery lasts through the night and most of the next day. You're heating the person, not the room, and that's roughly a 30x difference in energy.
The rated wattage is what the heating wire draws when it's on. It isn't on all the time. The controller switches the element on and off to hold your chosen setting, so on medium under a comforter the blanket might only draw power about half the time. We model 50% here. On high, or on top of the bed with nothing over it, it can run close to 100%; on low under a heavy duvet, well under half.
Two habits that stretch the battery. Pre-warm the bed on high for 20-30 minutes, then drop to low before you get in, since the warm-up is where most of the energy goes. And put the blanket under a comforter or quilt, not on top. Insulation over it means the element switches on less often. A queen-size dual-control blanket around 150W cuts every runtime in the table by about a third, but if only one side is on, you're back near the full-size figure.
One catch: many US blankets shut off automatically after a set period (often 10 hours), so an overnight runtime of 10+ hours doesn't help if the controller turns itself off at 4am. 12V heated blankets from the car aisle plug straight into a power station's DC socket and skip the inverter, though many have only high/low with no thermostat, so assume they draw their full ~50W the whole time. Wattage source: Virginia Cooperative Extension BSE-301 (single/double 60/100W); queen figure from manufacturer-rated 150W Sunbeam queen models. Check your controller's label.
How long real power stations run a heated blanket
Computed from each unit's rated capacity at 85% inverter efficiency and a 50% duty cycle (100W running). Units whose continuous output can't run it, whose motor-start surge can't start it are excluded. Where a maker's headline surge only applies to resistive loads, we size starts off continuous output.

How long will a power station run an electric blanket?
For a 100W full-size blanket cycling about half the time, a 500Wh unit runs roughly 8.5 hours, a 1,000Wh unit about 17 hours, and a 2,000Wh unit about 34 hours. A 150W queen cuts those by a third; a 60W twin stretches them by about two thirds.
What size power station do I need to run an electric blanket?
For one blanket overnight, 500-700Wh is enough with margin. Want two blankets plus phone charging through a two-night outage? Look at 1,500-2,000Wh. Surge isn't a factor; blankets are resistive loads with no motor start.
Do electric blankets use a lot of electricity?
No. A full-size blanket averaging about 50W uses around 0.4kWh over an 8-hour night. That's a fraction of what any space heater uses in the same time.
How many watts does an electric blanket use on low?
The element's wattage is the same on every setting; the low setting just switches it on less often. So low might average 20-40W on a 100W blanket, depending on insulation and room temperature.
Can a Jackery power an electric blanket?
Yes, any current Jackery Explorer can. A Jackery Explorer 1000 v2 (1,070Wh) runs a 100W blanket cycling half the time for about 18 hours by our math. Smaller 300Wh-class units manage about 5 hours, which covers the coldest part of the night.
