After getting my battery packs charged all up and trying again. You have to plug it up press and hold the power button and then you can click through the 3 heat levels. After figuring it all out, so far this works fantastically! We'll see how long the battery packs I picked out lasts! Great product, definitely recommend!!
HearthCozy™ Heated Scarf
- Warmth where cold hits first
- Pull-through stays put
- USB-powered on the go
"I really like my scarf. When I first picked it up, I was disappointed, it felt so flimsy and thin. But the moment I turned it on, I was delighted. It's warm, soft, and comfortable. I bought my husband one too, and he wears it every day. We live in Maine, and this scarf makes winter almost enjoyable."
| Fit | One size — sits comfortably around most adult necks and shoulders |
|---|---|
| Colours | Black, Grey, Red |
| Battery | 3,000 mAh rechargeable power bank, included |
One size, and the pull-through design holds it in place.
No tying, no knot working itself loose while you walk. Drape it, pull one end through the loop, and it stays where you put it. The battery comes in the box, so there's nothing else to buy.
- Charge the battery. Charge the included 3,000 mAh power bank fully before you wear the scarf for the first time.
- Slip it into the pocket. The pocket sits on the inside, out of sight. Plug the USB connector into the battery, then tuck the battery in behind it.
- Put the scarf on. Drape it around your neck and pull one end through the loop so the heated panel sits flat across the back of your neck. The heat is concentrated at the back of the neck, so make sure that section is against your skin or over a thin layer — not bunched up under a collar.
- Press and hold for 3 seconds. The LED lights up and you'll feel warmth within about 30 seconds.
Layering under a coat? Put the scarf on first, then your coat, and run the pocket end inside. The battery sits against your body and stays warmer, which helps it hold its charge in the cold.
Your neck gets cold first, and the rest of you follows.
An ordinary scarf only traps the heat you're already making. On a cold morning that isn't enough — you end up hunching your shoulders, and by the afternoon your neck is stiff and aching. We built this around the three things that go wrong.
- Heat where the cold hits first. ThermoSphere™ heating runs across the back of the neck, the spot that goes cold before anywhere else. Warmth lands where you feel it, instead of being spread thin across the whole scarf.
- Warmth that loosens a stiff neck. Gentle, continuous heat helps tight muscles relax and supports circulation — the same idea as a heat pack, except you can wear it out of the house.
- Heat that lasts the whole day. Up to 8 hours of continuous warmth from the included battery. Commutes, dog walks, the school run, or sitting still at your desk.
Safe low-voltage heat. It runs on 5V USB power, the same as charging your phone. Built-in heat regulation helps prevent overheating and stretches your battery further.
What is it made of?
- Soft plush faux fur — lightweight and premium, warm against the skin without the bulk
- Integrated heating panel — sewn into the back-of-neck section, invisible from the outside
- Discreet inner pocket — holds the battery securely and out of sight
Light enough to layer under a coat, and it looks like an ordinary scarf with the heat switched off.
How do I care for it?
- Remove the battery first. Always unplug and take out the battery before you clean it.
- Hand-wash or spot-clean. Cold water with a mild detergent. Don't wring or twist it.
- Lay flat to dry. Air-dry completely before you wear it or plug it back in.
- No tumble dryer, iron, bleach or dry cleaning. All four damage the internal heating elements.
What's in the box
- 1 HearthCozy™ Heated Scarf
- 1 3,000 mAh rechargeable battery
- 1 USB charging cable
- 1 user manual
Everything you need is in the box. Charge the battery, drop it in the pocket, and you're ready to go.
Between seasons. Store it flat or loosely folded, somewhere dry, with the battery removed. Don't crease the heated panel.
| Setting | Best for |
|---|---|
| Low | All-day wear and the longest runtime — up to 8 hours |
| Medium | Cold days out and about |
| High | Warming up fast, or standing still in the cold |
The battery comes with it.
A 3,000 mAh rechargeable battery is included, so there's nothing extra to buy. It sits in the inner pocket and recharges over USB. If you want longer days out, any standard 5V USB power bank works as a spare — the scarf will take whatever you plug into it.
Using the button
- Press and hold 3 seconds to turn it on. The LED lights up and warmth arrives in about 30 seconds.
- Press once to cycle through Low, Medium and High.
- Press and hold 3 seconds again to turn it off.
Getting the most from your battery
Low draws the least power and gives you up to 8 hours. Medium and High are warmer and run the battery down faster, so start on High to take the chill off, then drop to Low to keep it going. Charge it fully before your first use, and keep it topped up over the winter.
Charge it overnight. Leave the battery plugged in with your phone, and it's ready to drop into the pocket on your way out.

These may be a little smaller than some other ones, but these have all worked and still work. I bought some others earlier, more expensive, that quit working just a few weeks, outside of the return window though. But these have kept working. And battery life with a relatively small power pack is really good. I cannot be happier. My wife gets a lot of color choices too.
For those saying you couldn't get them to charge or hold a charge, that's not how these work. It clearly states that it must be plugged into a power bank. The scarf itself does not charge and it does not heat without actively being plugged into a power source. I plugged it in and it heated up in less than 5 seconds.
I bought these for my husband because he had neck surgery. We have had them a year and they have been a real lifesaver! We went camping recently where it was about 19 degrees and the scarves kept his neck from hurting.
Very soft, great price for 2, comfortable, heats quickly and very warm. Quick delivery!
Worked well, I love them
