Do I need this if I am buying the Wrap?
No. Every Wrap comes with one of these already. Buy this only if you want a spare, a second one for another room, or one for a wrap you already own.
Why this one?
The 5V 2.1A output is what the heating panel wants. Small or older banks cut their own power when the draw is low, which feels exactly like a wrap that will not heat. At 20000mAh it has the capacity to run the Wrap and still charge your phone.

Where it earns its keep
The places it gets used most are the ones with no plug and no way to warm the room.
In a freezing office
The building you do not control the thermostat for. It stays on your shoulders while you type instead of sliding off.
The garage and the early start
Unheated spaces you are only in for an hour, and mornings before the car has warmed up.
For the cold one in the family
Most people buy this for someone else. The person who is cold in July and has opinions about the thermostat.
It is warm before you switch anything on. The heat is what you add when it is genuinely cold, so a flat power bank never leaves you with nothing.
What makes it work
No cord to the wall
The panel runs off a USB power bank in the front pocket. Stand up, walk out to the garage, and the warmth comes with you.
Oversized on purpose
About 38 inches of polyester sherpa. Room to pull your knees up with the hood on and your hands in the pocket.
It goes in the wash
Take the bank out, close the USB cap, machine wash. Tumble dry low and the sherpa stays soft.
Why the warmth never lasts
Everything you already own either traps heat or stays in one room. This one makes its own, three ways, from one button on the pocket.
HighMost heat
MediumIn between
LowGentle
One button on the front pocket cycles through the three, and holding it three seconds switches the heat off. We have not printed a temperature or a runtime here, because we have not measured one ourselves yet.
| Evenfold Wrap | A throw | A space heater | |
|---|---|---|---|
| Makes its own heat | Yes, three settings | No, it traps yours | Yes |
| Warmth follows you | Yes, bank in the pocket | The fabric does, the warmth does not | No |
| Works outdoors | Yes, no cord to the wall | If you can hold it on | No |
| Ready to use on arrival | Yes, battery included | Yes | Yes |
What you get
Everything you need to use it the day it lands. Nothing to go out and buy first.
- The Evenfold Wrap, in the color you pick
- A 20000mAh USB power bank, rated 5V 2.1A, which is the output the heating panel wants
- The USB lead, already fitted, running into the front pocket
- The heat button, sewn onto the front of the pocket
Two parcels, two tracking numbers. The power bank ships from our US warehouse and usually arrives within a few days. The wrap comes from our manufacturing partner and takes 8 to 12 days. That is not a mistake, just two different origins.
Questions people ask first
Straight answers, including the awkward ones.
30-day money-back guaranteeChange your mind for any reason within 30 days of delivery and send it back for a refund. If it does not heat, or arrives damaged, we pay the postage both ways.
Is the power bank really included?
Yes. Every Wrap comes with a 20000mAh bank rated 5V 2.1A. We used to leave it out and let you supply your own, and the single most common complaint about this style of wrap, everywhere it is sold, is arriving without one. So now one is included with every Wrap, shipped in its own package, and the price reflects it.
Why not just buy this on Amazon?
You should look. Plenty of heated wraps on Amazon look like this one, and some of them are cheaper. Read the one-star reviews on any of them and the same complaint comes up again and again: it arrived with nothing to power it, or the battery that came with it could not run the heat.
Ours comes with a 20000mAh bank rated at the output the panel actually wants. It ships in its own package, usually ahead of the wrap, so it is ready the evening the wrap lands. You get 30 days to send it back for any reason, we pay the postage both ways if it does not heat, and when you email us a person answers.
If you find a listing that includes a proper battery, takes real returns and has a human on the other end for less than ours, buy that one.
Can I use a power bank I already own?
Of course. Any certified 5V USB bank will run it. One rated around 5V 2A or higher drives the panel more reliably than a small keyring-sized bank, which is exactly why we picked the one we include. It sits in the front pocket alongside your hands, since there is no separate battery pouch. A laptop port or a plug adapter works too if you are staying put.
It is not heating up. What do I do?
A blinking red light almost always means the power bank, not the wrap. Banks cut their own output when they detect a low draw, and that looks exactly like a wrap that does not work.
Plug the lead into a laptop port or a plug adapter first. If it heats there, the wrap is fine. Then check the included bank is charged and the lead is pushed fully into the connector in the pocket.
If a wall adapter and the included bank both fail to heat it, it is genuinely faulty. Contact us and we will replace it or refund you, and we pay the postage.
How warm does it get, and is it warm without the heat on?
One button on the front of the pocket cycles three settings, high, medium and low, with the light changing color at each. Hold it three seconds to switch off.
We have not published a temperature or a runtime, on purpose. Listings for this style of wrap quote figures that come straight off a factory spec sheet. We would rather put a probe on our own unit, time it on our own power bank, and print what we actually measure. Those numbers go here when we have them, and they will say how they were taken.
And yes, it is warm before you switch anything on. It is thick sherpa cut very generously, and plenty of people use it that way most of the time.
What size is it, and how heavy?
One size, about 38 inches (96 cm), cut oversized on purpose. Where the hem lands depends on your height: around the knee if you are tall, closer to the ankle if you are shorter. It goes over your head like a hoodie, so it does not open down the front. It has real weight to it, closer to a weighted blanket than a hoodie, which is part of why it feels warm before the heat is on. Five colors.
Can I wash it?
Yes. Take the power bank out, close the cap over the USB connector, then machine wash. Tumble dry low and the pile comes out fine. Air drying a garment this thick takes the best part of a day. It is 100% polyester, so spills can leave a mark and a darker color is safer if you eat on the sofa.
How long does delivery take?
The power bank usually lands within a few days from our US warehouse. The wrap leaves the warehouse within 1 to 3 business days and most arrive within 8 to 12 days of ordering. You get a tracking link for each. We ship within the US only.
Is it safe to use?
It runs on low-voltage USB rather than mains, so there is no wall socket involved, and a sensor cuts the heat if it detects an abnormal temperature rise. As with any heated garment, do not use it while asleep, on children, or if you cannot reliably feel changes in temperature. If it ever feels too hot, unplug the bank.
What is Evenfold?
A small shop that sells one thing properly. Named for the part of the evening when the lights go low and everyone else in the house is finally warm enough. We started it because the warm things most of us own only work while you sit still, and we wanted one that did not.
