- Reviewed in the United States on December 18, 2024Color: FloraFlameVerified PurchaseThese magnetic hand warmers are an absolute game-changer for cold weather! Whether I’m out walking, commuting, or just relaxing on a chilly evening, they provide instant, comforting warmth.
Design & Portability:
The design is nothing short of genius and adorable! These hand warmers are compact, lightweight, and slim enough to fit perfectly in my pocket, gloves, or even a small bag. The magnetic feature is a standout—it keeps the warmers securely together when not in use, so I never have to worry about losing one. Despite their small size, they deliver big on warmth, making them ideal for both everyday use and outdoor adventures.
Ease of Use:
Using these couldn’t be easier. They heat up quickly and stay warm for hours, perfect for those long winter outings. The intuitive controls let me adjust the heat level with a simple press, and I appreciate that they recharge quickly, so I’m never left without them.
Comfort & Versatility:
The shape and size make them incredibly versatile. I slip them into my gloves during walks, tuck them into my coat pocket for a quick hand warm-up, or toss them in my bag as a backup. They’re even small enough to nestle into the palm of my hand without feeling bulky. The smooth finish feels great against my skin, and they’re lightweight enough to carry around all day without noticing.
Battery Life:
I was blown away by the battery life. Even on the highest heat setting, these warmers last long enough to get me through a full day outside. The magnetic charging system is efficient and convenient, making it easy to keep them ready for use.
Final Thoughts:
These magnetic hand warmers are a must-have for anyone dealing with cold winters. Their portability, reliability, and sleek design make them the perfect companion for outdoor activities, commuting, or even just keeping cozy indoors. They’ve become my go-to for staying warm, and I honestly don’t leave the house without them.
10/10—Highly recommend for anyone who values warmth and convenience in a stylish, pocket-friendly package!
- Reviewed in the United States on February 21, 2025Color: Starlit BlackVerified PurchaseThis product does what it says my husband tried these out abs he said that on the high setting it was super hot, so he kept them in his pockets on the low settings and that on one full charge low settings lasted his full 12 hours shift. They are very durable and made from great material, and small for transport and storage, works great, long battery life.over a great product for the price.
- Reviewed in the United States on May 1, 2025Color: BlossomVerified PurchaseThese are a great find! Versatile with use. Whether you keep in your pocket sledding or sitting at your desk and need to warm your hands up. They heat up quick. The design perfectly fits in your hand. Love the functionality of recharging them and creating less waste with one time use hand warmers. We gave these as teacher gifts which was a huge hit!
- Reviewed in the United States on March 13, 2025Color: Glacier BlueVerified PurchaseThe item works as advertised! The handwarmers are small, portable, pretty, and easy to use. I haven't been able to test out the battery life yet but I'll update my review if it's bad. The durability of the warmers is questionable. I accidentally hit it against something in my car and the metal part became damaged. There wasn't a lot of force used either (one star was docked). Only the metal part of the hand warmer heats up and I wish it did both sides (I know why it wouldn't work logistically). The magnetic side is super convenient for traveling and keeping the two warmers together. Overall, this would be a good holiday gift or something to give a friend moving to a colder place!
- Reviewed in the United States on May 6, 2025love these hand warmers. they keep you warm in the coldest of temps. they stay charged for days. easy to use. and not to big to store.
- Reviewed in the United States on January 10, 2025Color: Dark BlueVerified PurchaseI didn't really need these and neither did I really want to spend $20 on them. But I read the reviews and took a chance and there was a discount if I remember correctly. They are tiny (a guy's hand might need bigger ones) and comfortable. And, my favorite, they are rechargeable! They have three heat settings but I have only used the lowest which I found adequate. I find them particularly handy when out walking and taking photos. I don't have to struggle to get gloves off so that I can snap a photo. They also warm up my pockets. The only heat on one side but they click together magnetically for storage in a nice little pouch.
- Reviewed in the United States on March 28, 2025Color: Starlit BlackVerified PurchaseI use these at work in those cold upstate ny winter nights outside. They heat up fast. Just be careful to keep it at the right setting if you put into your gloves . You can easily hit the button and it gets warmer quick. They hold a good charge and have helped many times this past winter. I would recommend these to anyone that asks about keeping their hands warm in the winter. Also the daul charging cable is great. I use it for other stuff as well when out of town for work.
- Reviewed in the United States on March 10, 2025Color: Starlit BlackVerified PurchaseGood size to fit snug in my palms (I wear size M in women's gloves). They get warm super quick and so far I've never turned it up to the highest; low always does the trick. The best part is how the two warmers are magnetic so they clamp together back to back so you can wrap your fingers around and have even more skin touching the warmth. I'm thinking at some point I'll buy another pair. Recently took a winter walk and when one of the kids took their gloves off to play in the snow, then wanted to go home early "because my hands are too cold!" I whipped these out of my pocket and the kids were so fascinated with how toasty they were, pretty soon they were all claiming their hands were freezing LOL

NadineReviewed in Germany on December 17, 2024
5.0 out of 5 stars Super
Color: BlossomVerified PurchaseMan kann die Wärmestufen einstellen (3Stück an der Zahl)
Akku hält lange, wie lange kann ich nicht genau sagen. Aber definitiv einen kompletten Tag draußen. Nach 4 Stunden (30 Minuten volle Leistung, 3.5 Std mal auf Stufe 1 und 2) nur weniger als 1/3 aufgebraucht.
Auf Stufe 3 sind die wärmer wirklich sehr warm. Auf purer Haut nicht allzu lange aushaltbar. Aber wenn man überlegt, dass man ich die Stufen selbst einstellen kann so heiß wie man will und so wenig wie man braucht sind die echt perfekt.
Auch sehr praktisch und ein klarer Vorteil gegenüber den Handwärmern mit Gel und ,,Knickchemie".
Kan. Ich wirklich jedem empfehlen der lange draußen ist und es gerne warm mag.
Handgelenkschlaufen sorgen für Sicherheit. Man kann sie nicht verlieren.
Liegen gut in der Hand und können tatsächlich einfach in den Handschuh gesteckt werden.
Schön klein aber trotzdem die ausreichende Größe um zu wärmen.
Bin super zufrieden.
Gleich 2x als Geschenk gekauft
- Caden H.Reviewed in Canada on February 11, 2025
5.0 out of 5 stars These pack a punch!
Color: Glacier BlueVerified PurchaseCute small hand warmers that pack a punch. I personally find level 1 (lowest temperature) too hot to place directly against my skin, but like having them in my mittens to warm the air around my hands. Also, when I'm wearing two pairs of socks, I stick the warmer between the two layers against my inner calf which warms up the blood going down into my feet. This warms my feet without having to fit the warmer in my boot which would be uncomfortable. I am pleased with the battery life and features of the product. My only complaints would be that the heaters are too hot, and also that it is easy to accidently press the button to change the temperature during use.

5.0 out of 5 stars Pequeño y práctico
Color: Starlit BlackVerified PurchasePequeño y agradable la tacto. Tener cuidado porque si leéis atentamente las instrucciones dice que viene con un cargador dual una bolsita y dos cuerdas para atarlo, lo cual esta todo incluido en la caja en la parte trasera en un lugar minúsculo, yo ya lo estaba envolviendo para devolver porque pensé que venía sin esos accesorios, pero justo en el último momento me dió por mirar en esa parte de la caja.
