Perfect for those who doesn't like gloves.
Since, I'm not a gloves person, this is amazing and very useful during the last few cold days. Very light to carry on pockets, easy to charge and the design and size of it fits perfect to keep my hand warm, and it does last long; used it for two days without charging it.

Lots of heat in a small package
Nice compact size, get surprisingly hot (maybe uncomfortably hot for some people), and have a good battery capacity (8 hours at power level 1, and I can't imagine needing to go to a higher level). At first, the magnets that hold the warmers together seem a little weak, but after removing the protective film on the back of each unit, the magnets prove perfectly adequate. The packed in drawstring bag is a nice and useful touch.

Work really well great for people who struggle with cold hands or anyone working outside
These are fantastic bought for husband who has arthritis in his hands which get very cold and they've been a game changer when he's working outside. Heat up very quickly 3 different heat options the 3rd is very hot Ideal to leave in your pockets or even the inside pockets to keep your body warm. The magnet is ideal to keep them together when not in use or to hold in both hands at the same time They come in a little velvet pouch for easy storage also with a charging cable. They hold charge well and don't take long to charge back up once flat. Had these a year and still work perfectly recently bought another set for my mother who also swears by them definitely recommend.

Warm hands
We haven’t had them long so can’t give them top marks yet but they are a clever product. Not sure how long the batteries last but they are rechargeable. They get really quite hot but you can vary the temperature. Handy if you are a spectator freezing on a sports field.

Winter Essential - Powerful Little Hand Warmers - Warm in Seconds
Where have these been all my life? I absolutely adore them. They warm up almost instantly and have a really good battery life. I mostly use them when working in the office, as my hands get very cold, but I recently put the wrist bands on and tucked them into my gloves while de-icing my car — my palms were toasty. Once I’d finished, I used them to quickly warm my fingers again. They’re just the right size, fitting nicely into my palm, and they also feel really nice to hold. The included pouch is a lovely touch and keeps them safe when not in use and the charging cable allows you to charge them at the same time. I’m so happy with these, my best buy of 2025 and would highly recommend them.

LOVE THEMM
I love these hand warmers I brought them not really knowing what I expected. They are great value for money and they fit perfectly in hand and pockets. They are 3 different settings which all have very good warming. They are perfect I love them and very good and functional

Cute and a winter mood booster
I’ve had these for a couple of weeks now and they’re a total mood booster now that the weather has turned super cold for winter. They’re reasonably fast to charge via usb - only takes a couple of hours and the lights indicate where it’s up to, they’re simple to use, and have three temperature settings. I really only need the low setting to warm up my pockets though. They’re smaller than I thought they’d be but actually a good size and they warm up fast. The design is also pretty cute! Super happy with them.

Great hand warmers
Great product, perfect for cold days out. Very easy to use with different heat settings, we got about 7 uses out of the battery charge. Perfect gift idea.

Irgendwo habe ich noch übliche Handwärmer, die man mit heißem Wasser wieder auflädt. Nutzen tue ich sie leider nie. Entweder weil ich sie vergesse oder sie nicht einsatzbereit sind. Oder ich einfach zu bequem bin, sie wieder im Topf mit Wasser so lange zu erhitzen, bis sie wieder nutzbar sind. Seit meinem letzten Umzug sind sie verschollen, ansonsten hätte ich sie genau jetzt aus Neugierde wieder hervorgekramt. Geärgert habe ich mich aber im Winter schon öfter, dass ich keine Handwärmer dabei hatte. Der Vorteil der elektrischen Handwärmer: Man kann sie einfach in der Jackentasche lassen, ohne dass man Sorge haben muss, dass sie versehentlich ausgelöst werden. Dabei hilft auch eine kleine Transport- und Aufbewahrungstasche. Die Handwärmer sind kleiner als gedacht und passen bequem in die Hand. Ein Doppelklick auf den Bedienknopf zeigt den Ladezustand an (mit 3 blauen LED-Punkten). Ein langer Druck auf den Bedienknopf aktiviert das Aufheizen. Mit jeweils einem weiteren Druck auf den Knopf lässt sich die Heizstufe verstellen. Derer gibt es drei: Niedrig (42 Grad). Mittel (46 Grad). Hoch (52 Grad). Angezeigt mit jeweils ein bis drei roten LEDs. Ein langer Druck auf den Knopf deaktiviert das Gerät. Bereits die niedrige Stufe lässt das Gerät recht warm werden. Bei eisig kalten Fingern im Winter könnte es schon fast zu warm werden. Allerdings ist hier dann zusätzlich noch die deutlich kühlere Außentemperatur zu berücksichtigen, d.h. das Gerät muss dann mal eben 25 Grad oder mehr zusätzliche Temperaturdifferenz überbrücken. Eine echte Aussage zum Verhalten kann ich daher erst im Winter treffen. Die kleinen Heizpads erwärmen sich sehr schnell nach dem Einschalten, kühlen sich nach dem Ausschalten aber auch relativ schnell wieder ab. Beheizt ist nur die schwarze, konkave Oberseite. Extrem überrascht hat mich die angegebene Akkulaufzeit von 4h bei höchster Heizstufe, bis zu 8h bei niedrigster Stufe. Sollte wirklich ein 2500mAh Akku in jedem der kleinen Handwärmer eingebaut sein, dürfte Größe und Gewicht größtenteils auf den Akku entfallen. Ich bin gespannt auf den Winter. In meinen Tests hatte ich die Akkus nicht aufgeladen und sie zeigen seit Beginn der Tests immer noch dieselbe Ladestufe an. Die kleinen Dinger können auf jeden Fall länger für warme Finger sorgen als die üblichen Handwärmer. Damit hatte ich nicht so wirklich gerechnet. Weitere positive Aspekte: - Die Ladebuchsen sind mit einem Silikonstöpsel geschützt, d.h. Schlüssel und Co können keinen Kurzschluss erzeugen. - Die Handwärmer können um 180 Grad gegeneinander gedreht gegeneinander magnetisch befestigt werden. So lassen sie sich platzsparend im Transportbeutel unterbringen oder man hat einen größeren Handwärmer für große Hände. Benötigt man halt noch ein weiteres Set, wenn man die "großen" Handwärmer bevorzugt. Von mir bisher volle 5 Sterne. Im Winter dann ein Update :)

Je les utilise dans les gants en balade. Ils remplissent parfaitement leurs fonctions ! Je suis très satisfaite de cet achat.

Bought these to help with arthritis and help keep my hands warm during cold weather. They're compact, fairly lightweight, were a good price, and seem to be of pretty good quality. They charge up pretty fast (about an hour or so from almost dead to full charge), act as an emergency mini-power bank too (haven't tried that function yet), and get reasonably warm quite fast. They won't get hot, just warm, but for me that's enough. They come in a pair and a split charging cord and two little drawstring storage bags are included. Five stars, good product.

Questi scaldamani elettrici sono davvero ottimi, costruiti con materiali eccellenti e una fattura che trasmette cura e attenzione ai dettagli. A differenza di molti altri modelli che emanano un fastidioso odore di plastica o componenti elettronici, questi sono del tutto inodori, un punto a favore che ne migliora l’esperienza d’uso. Un dettaglio intelligente è il magnete integrato, che permette di tenerli uniti quando non si usano. Tuttavia, la vera innovazione sta nel fatto che possono essere utilizzati separatamente, uno per mano, offrendo flessibilità e comodità. Dopo due inverni di utilizzo, posso dire che il prodotto è duraturo e affidabile. Le diverse impostazioni di temperatura sono ben calibrate e soddisfano ogni esigenza. Un acquisto che consiglio senza riserve: se cercate scaldamani funzionali, pratici e ben fatti, questi sono la scelta ideale!
