Shaded rows are our picks. Assumed load: A twin-size electric blanket averaging 60W on a middle setting for an 8-hour night, plugged into the AC outlet.
How much power an electric blanket uses
A twin-size electric blanket on a middle setting averages about 60 watts. That is small because a blanket warms you directly. It does not try to heat the air.
A space heater takes the other route. It pulls 1,500W on high, the same as 25 blankets, and in a tent the warm air leaks out through the thin walls. This is why a 2,000Wh station runs a space heater for 1.2 hours and a blanket for about 3.6 nights.
A watt-hour counts energy: one watt, used for one hour. Eight hours at 60W is 480 watt-hours a night. The blanket plugs into the AC outlet, and after losses the sizes work out like this. A 300Wh unit gives about half a night. The 768Wh unit gives 1.4 nights. The 1,000Wh class gives 1.8 to 1.9, and the 2,000Wh class gives about 3.6.
What changes the number
The setting. High draws more than the 60W middle setting, and low draws less. This is the biggest lever you have.
The size. A queen or king blanket has more wire to heat than a twin. The watts are printed on the blanket’s label or controller, so check yours and scale the table to match. A 120W blanket halves every runtime.
What is on top of it. A blanket under a sleeping bag or quilt holds its heat, so you can turn it down. One lying open to cold air loses its heat as fast as it makes it.
Pre-heat, then turn it down
The cheapest trick is timing. Run the blanket on high for half an hour before bed, while you get ready. Then drop it to low, or switch it off once you are warm. Your sleeping bag holds the heat you banked.
This is how a small station becomes useful. A 300Wh unit cannot run 60W all night, but it can pre-heat the bed and cover the cold hours before dawn.
A 12V blanket skips the inverter
A power station stores DC power. To feed a normal blanket, it has to make household AC with a part called an inverter, and some energy is lost on the way. Our math counts 85% of the battery as usable through the AC outlet.
12V blankets exist. They plug into the car-style socket and take DC straight from the battery, so the inverter stays off. In our math the 12V socket delivers 90%. Check the blanket’s watts on its label and run the same sums.
Cold weather is hard on the battery
Two honest warnings. First, batteries hold less in the cold, so expect fewer hours on a freezing night than the table shows. Second, most lithium iron phosphate batteries, the type common in power stations, will not accept a charge below freezing. A solar panel on a frosty morning may do nothing until the station warms up.
So keep the station inside the tent with you, or in an insulated box. Set it on a foam mat or a folded towel, not on bare frozen ground. Do not leave it in the car overnight, where it will be as cold as the air outside by morning.
Start with what is under you
Cold ground pulls heat out of you all night. A good insulated sleeping pad under you does more than extra watts, and it uses no battery at all.
Follow the blanket’s own label as well. Most say to lay it flat and not to fold or bunch it while it is on.
The picks in detail
Jackery Explorer 1000 v2
- 1.9 nights
- Electric blanket
- $499
- $0.47 per Wh
- 23.8 lb
- Weight
15.2 hours at 60W is 1.9 eight-hour nights. Pre-heat the bed on high, then turn the blanket down, and two nights is within reach. At 23.8 lb it is the lightest 1,000Wh unit in the table, and it costs $499, or $0.47 per watt-hour. The same battery would run a 1,500W space heater for 0.6 hours. That gap is why a blanket is the right way to stay warm on battery power.
What fits
- 1.9 nights per charge
- 23.8 lb, lighter than the other 1,000Wh units
What does not
- Just short of two full nights at 60W
- 400W solar input is low for refilling at camp
Jackery's list price is $559, and it has sold for less at other retailers. Jackery rates its 4,000 cycles to 70% capacity, not 80%.
Bluetti AC70
- 1.4 nights
- Electric blanket
- $359
- $0.47 per Wh
- 22.5 lb
- Weight
10.9 hours is one full night with about 3 hours to spare. That spare is useful, because a cold battery gives up less of its energy. It costs $359, which is $140 less than the Jackery. On a two-night trip you would need to recharge on day two. From a wall outlet it reaches 80% in 45 minutes, and its 500W solar input leaves room for a good-sized panel.
What fits
- 1.4 nights per charge
- 45 minutes to 80% from the wall
What does not
- Not enough for two nights
- Only 1.3 lb lighter than the 1,000Wh Jackery

Anker Solix C2000 Gen 2
- 3.6 nights
- Electric blanket
- $899.99
- $0.44 per Wh
- 41.7 lb
- Weight
This gives 3.6 nights for one blanket, or about 1.8 nights for two people running one each. Anker lists a 9W idle draw, low for this size, and that counts when a small load runs all night. Its 800W solar input is double what the Jackery 2000 accepts, so panels can refill it faster at camp. At 41.7 lb, it suits sites where the car parks next to the tent.
What fits
- 3.6 nights per charge
- $0.44 per watt-hour
- 800W solar input
What does not
- 41.7 lb
- $899.99 is a lot to spend on a warm bed
Anker's list price is $1,499.99. Anker lists a 9W idle draw, which is low for this size.
Anker Solix C300
- 0.5 nights
- Electric blanket
- $249
- $0.86 per Wh
- 9.1 lb
- Weight
It gives 4.1 hours at 60W, about half a night, so it cannot keep a blanket on until morning. It can warm the bed for an hour before you get in and then cover the coldest stretch before dawn. At 9.1 lb and $249, that suits mild-weather camping. It was sold out at Anker's own store at last check. The 8.2 lb Jackery Explorer 300 v2 gives the same 4.1 hours, but at $299 it is only $60 less than the AC70.
What fits
- 9.1 lb
- $249, which is $110 less than the AC70
What does not
- 4.1 hours is about half a night
- Sold out at Anker's own store at last check
Sold out at Anker's own store when we checked. The price shown is its last list price.
Verdict
Buy the Jackery Explorer 1000 v2 for a two-night weekend. It gives 1.9 nights and is the lightest unit of its size. Pick the Bluetti AC70 for single nights or if you can recharge between them. Choose the Anker Solix C2000 Gen 2 for longer trips or two blankets. The Anker Solix C300 only pre-heats the bed. Whichever you pick, spend on a good sleeping pad first, and keep the station out of the cold.
How these numbers were worked out. Runtime = battery capacity × efficiency ÷ average watts. We use 85% efficiency for AC outlets and 90% for DC and USB ports, because some energy is lost as heat on the way out. A model is marked "can't run it" when the device needs more watts than the outlet gives, or a bigger startup surge than the unit is rated for. Your own device may draw more or less than our assumed load, so treat these as estimates. Prices were checked on 2026-10-04 and change often. Full method
