OCOOPA Magnetic Hand Warmers Rechargeable 2 Pack, UL Safety Heat 100-126°F, 3-Settings, Pocket-Sized, Max. 8 Hrs Long Lasting,Great for Raynauds, Golf, Hunting, Camping, Gifts for Men Women, UT3 Lite

I purchased these after I froze my butt off on vacation in Japan. I had the disposable one-time-use hand warmers and those completely failed me on that trip, so I wanted something more reliable. Performance: These work better than I thought they would. Small but powerful - they warm really quickly and hold heat well. The double-sided design means both hands get warmth. Temperature settings: Has different temperature settings (100-126°F) so you can adjust based on how cold it is. I appreciated being able to control the heat level. Battery life: These last a long time off a single charge, which was a huge improvement over disposable warmers that would die when I needed them most. Portability: Compact size - small enough to put in my pockets without being bulky. Comes with lanyards if you want to attach them to your wrists instead. Charging: Includes a USB-C charging cable, which is convenient since that's what most devices use now. Bottom line: If you're traveling somewhere cold or just need reliable hand warmers, these are absolutely worth it. Way more economical and dependable than disposable ones. Wish I'd had these in Japan!

Compact warmers which heat up very quickly. Worked extremely well for a NFL playoff football game in the Northeast's cold weather. Battery life was good, lasted the entire game on the low setting, but that was more than enough to keep my hands warm. High was warmer than standard chemical hand warmers. They come with a dual USB-A charger with two USB-C outputs to charge the warmers, or you can use your own USB-C cables. Note that these only heat on one side, so if you're holding it in your hand you might rotate it periodically. While they do have magnets to hold them together they are quite weak and don't work all that well. They do come with a small felt bag for storage. Charge time is slow, so if you're going to be out for a long time you might want to consider a second set.

They work really well. Warmth on level 1 is pretty good for most situations. Level 2 is good when extra cold or windy out. I have not needed level 3. Battery life is decent for being a heating unit. The first one or two charge cycles didn't last as long but the battery has been great since. Still need a backup, like the iron oxidation packs, if you are outside for extended periods. The size and curvature fit my hands well (For reference, large size nitrile gloves and most regular gloves fit snug & smooth on my hands). To warm my whole hand I prefer holding the pair in one hand (they only heat on one side). I liked these enough that I bought a second pair for my other hand. I also bought my neighbor a pair, and spare pairs for my wife & hunting bag. Watch the price for a while. First pair was 30+ bucks, but the rest I caught on big discount that was almost half price.

I’ve been using these OCOOPA hand warmers for a little while now, and overall I really like them. They definitely get hot — I’d guess close to the 125°F they advertise — and that temperature is perfect for actually warming your hands. As someone with mild Raynaud’s, the heat really does make a difference, and these offer quick relief when my fingers start to go cold. The downsides are mostly around practicality. The battery life is fine, but the charge time feels slow. When I run them on high, it seems like they take almost as long to recharge as they last. The included Y-shaped charging cable was a nice idea in theory, but one of the two output ends on mine didn’t work at all, so I ended up charging one side at a time anyway. OCOOPA’s model system could also be clearer. The numbers (3, 4, etc.) feel random — if the “4” is supposed to be better than the “3,” I really can’t tell how based on their descriptions. On top of that, the sizing isn’t consistent: some models list measurements in centimeters and others in inches. It makes comparison way harder than it should be. For larger hands, these are on the small side. They still help, but they don’t fill your palm the way I’d like. I also ordered another OCOOPA model with heat on both sides and I prefer that one. Its a nice feature that warms more evenly and works just as well overall. I’d recommend a 2-sided model if you’re deciding between the two. One major downside of both models is the size. Yes, small makes them portable and easy to fit in your pocket, but these do not work great for people with large hands. Still, the heat output and reliability make this a solid 4-star pick — great for cold hands and Raynaud’s, with room for improvement in design and charging.

Purchased for a friend of mine during the cold this past winter. They were everything advertised and she loves them. The quality was excellent, price imo was amazing for the rechargeable warmth given. She is a teacher and carried them every day after receiving them this past winter. One thing not advertised, we were video chatting and she told me she had a headache and rubbed her neck as if the headache was originating from the muscles in her neck, maybe from working on a computer for a long period through the day. I recommended using these hand warmers as a heat source and placing them on her neck. She said the heat generated helped tremendously in relaxing the muscles in her neck and ultimately her headache. The size, portability and magnetic construction helps her keep them in her pocket or bag without adding noticeable bulk to her what she already carries daily. Highly recommend this product and there are several different colors also, in case men would like some but maybe don’t want the pink color

Chauffe main petit et pratique facile a utiliser

It works really well! Served us well on our vacation in London and Scotland in Dec and Jan. Starts functioning in a couple of seconds and works for hours. Great product!

Arrivate nelle tempistiche e nelle condizioni che Amazon rappresenta. Il prodotto è piccolo e maneggevole, esteticamente bello e comodo da portare in giro. Si scaldano davvero subito e durano esattamente come dichiarato. Facili da ricaricare e con una pratica sacca per il trasporto. Prodotto consigliato.

Questi scaldamani sono ottimi, si ricaricano abbastanza velocemente e durano a lungo. Sono molto caldi, hanno tre livelli di riscaldamento ma io li metto sempre a uno perchè già così sono caldissimi.

Questi scaldamani sembrano due mouse per il pc in scala ridotta, stanno nel palmo di una mano, come è giusto che sia. Un magnete, posto sul retro, provvede a tenerli uniti quando non in uso. C'è anche in dotazione una custodia morbida. Sono apparecchi ricaricabili, con una batteria ai polimeri di litio da ben 2500 mAh in ciascuno dei due scaldamani e si ricaricano tramite una presa usb-c in ognuno. Viene fornito un cavetto da usb-a ad usb-c sdoppiato, in modo da poter caricare entrambi i dispositivi con una sola presa usb. La corrente di carica è di 1A, quindi la ricarica è un po' lenta, ci vogliono un paio d'ore abbondanti. Quando li ho avuti tra le mani ho subito riflettuto sul fatto che ci sia una batteria li-po di capacità abbastanza alta, praticamente a contatto con una resistenza che sviluppa fino a 55°C. Mi sono tranquillizzato una volta testati, perché la parte posteriore non supera mai i 37 gradi, con la resistenza impostata alla massima potenza, quindi vedo che l'isolamento termico della batteria è ben curato e non dovremmo correre rischi di trovarci un falò nelle tasche. Tra l'altro, sto eseguendo i test con una temperatura ambiente di 28°C, quindi, in pieno inverno, anche la temperatura esterna più bassa aiuta a mantenere fresche le batterie. Veniamo al funzionamento. Una volta caricati, i due scaldamani si accendono premendo per circa un secondo il tasto presente su ognuno. Tre piccole spie, forse troppo piccole e davvero poco visibili, indicano il livello di potenza impostato. Ad ogni pressione si aumenta di un livello. Ai tre livelli corrispondono tre precisi livelli di temperatura: 40-45-50°C. La temperatura impostata viene raggiunta molto velocemente, nel giro di 30 secondi circa (loro dicono 5 secondi, ma forse vale solo per la minima), e mantenuta con precisione, oscillando di circa -3 gradi +5 gradi; la pagina prodotto dice 42/47/53°, io ho rilevato picchi superiori per poi stabilizzarsi, come ho scritto, a 40/45/50 di media. Alla massima temperatura, 50 gradi, penso si possano usare questi scaldamani solo con i guanti, perché scottano parecchio. A mani nude si può sempre tenere la temperatura minima di 40 gradi, più che adeguata e confortevole, che tra l'altro garantisce una lunga durata della batteria. Durata che, in base alle mie prove, rispecchia quanto dichiarato: 8 ore alla minima temperatura, 6 ore alla media, 4 ore alla massima. I miei rilevamenti si discostano di poco. Ma questi apparecchi si prestano anche ad un uso improprio, per chi, come me, spesso si trova a lavorare in pieno inverno, in ambienti non riscaldati. Chi utilizza elettroutensili a batteria, saprà bene che, con temperature molto rigide, le batterie non riescono a caricarsi. Beh, basta qualche minuto a contatto con questi scaldamani, e la batteria sarà pronta per la ricarica!!! 🔝 In definitiva un prodotto molto consigliabile.
