Safety information
Heat held against the skin for a long time can cause low-temperature burns, even at settings that feel mild. Please read before your first use:
- Do not sleep while wearing the jacket with the heating on.
- Use the lowest setting that keeps you comfortable, and turn the heat off from time to time instead of leaving it on for hours.
- Not suitable for anyone with reduced skin sensitivity (for example from diabetes or neuropathy), for anyone who cannot feel heat or operate the button, or for young children.
- Do not use on broken or irritated skin. Stop using it if you feel discomfort, itching or excessive heat.
- Always wear at least one layer between the heating panels and bare skin.
- Do not use a damaged cable or power bank, and do not modify the wiring. Disconnect and remove the power bank before washing.
- If you are pregnant or have a medical condition, check with your doctor before using a heated garment.

What buyers say about this jacket
Reviews left by verified buyers of this jacket on our manufacturer's marketplace listings. Reviews written in another language have been translated into English.
Top-notch product. The jacket's quality is excellent, better than I imagined. It reached my home in 15 days; the seller shipped it very quickly. Excellent service.
It warms the body well — I just hope the electronics last. It's already warm before you even plug in the battery. The cable sits in the pocket, easy to find and use. I'm 5'5" and 141 lb and ordered XL, and it fit great.
I loved it. Arrived very fast, very good quality.
Warm and wind proof even without power. Heating works well leaving me toasty. Great quality, very good stitching and zippers. Very happy. Sizing is Asian so L is small. I got XL and it's like a medium. Arrived very quickly.
It really works!
Nice jacket, works well.
Perfect product. I got the size right, and it really does warm you from the inside. Arrived in perfect condition, everything working. 10 stars for the store and the seller. I recommend it.
Arrived in excellent condition and ahead of schedule. Thank you.
Arrived extremely fast. It's already warm without even turning it on. Only works with a 2A output. I'm 6'3" and 192 lb, and the 4XL fit exactly right.
Color and size, perfect.
Very good product, really worth it. The only issue is that the XL runs small — I work out, so it was tight across the shoulders and back. Other than that, it's incredible.
I recommend the store and the manufacturer 100 times over. This is the second jacket I've bought from the same store and factory. You're the best!
Order a size up from the one you need — they run smaller than normal.
Does what it promises, but the sizes run very small. I'd recommend going up 3 sizes from what you normally wear.
It was a nice jacket but it doesn't fit me, a bit small. I should have ordered the next size up :(
Good to know
Questions, answered
No. The jacket plugs into any standard USB power bank with a 5V/2A output — the kind you use to charge a phone — which sits in the inside pocket. With a 10,000mAh power bank the manufacturer rates up to 8-12 hours of heat, depending on the heat setting and the temperature outside.
Order 2-3 sizes up from your usual US size — if you normally wear L, pick 2XL or 3XL. The Size guide next to the size selector has every measurement in inches and cm.
Disconnect and remove the power bank first, then hand wash or use a gentle machine cycle in cold water. Air dry only.
Three: 113°F (45°C), 95°F (35°C), and 77°F (25°C).
Orders ship within 1-3 business days and usually arrive 6-12 days after you order. If yours is running late, we'll email you with an update.
Do not sleep with the heating on. Heat held against the skin for hours can cause low-temperature burns even at mild settings, so use the lowest setting that keeps you comfortable, keep a layer between the panels and bare skin, and turn the heat off now and then. It is not suitable for anyone with reduced skin sensitivity, such as from diabetes or neuropathy. See the full safety information above.
