UT2S Magnetic Hand Warmers Rechargeable 2 Pack, 5000mAh Electric Handwarmer, 4 Heat Settings (100–137°F), 2s Fast Heating, USB-C Power Bank, Gifts for Gaming & Outdoor

These kept my fingers from falling on in the winter, they can be stuck together for one big hand warmer, or pulled apart for two smaller hand warmers for each hand. The battery life is great, but not last as long if you set them to maximum heat. I wish these were USB C, but use Micro USB B instead, and each one has to be charged separately. Apart from that nitpick, overall this is a great pickup for anyone who wants to avoid frostbite this winter.The OCOOPA Rechargeable Hand Warmers have quickly become my go-to winter companion. This 2-pack of magnetic electric hand warmers has exceeded my expectations in every way possible.Pros:Remarkable Heat Output: These hand warmers are incredibly effective at generating heat. The three heat settings provide customizable warmth, ensuring I'm comfortable in any chilly situation.Long-Lasting Battery Life: I'm consistently impressed with how long these hand warmers last on a single charge. Even on the highest setting, they keep my hands toasty for hours, making them perfect for outdoor activities or long commutes.Magnetic Closure: The magnetic design is a game-changer. It allows me to attach the hand warmers to my jacket, belt, or any metal surface, ensuring they stay in place and freeing up my hands for other tasks.Multi-Purpose Design: These hand warmers aren't just for your hands. They can also serve as power banks for your devices, which has come in handy more times than I can count.Compact and Portable: The slim, ergonomic design of these hand warmers fits comfortably in my hands and pockets. They're incredibly easy to carry around, making them a must-have during winter outings.Quick Recharge Time: When the battery runs low, the hand warmers recharge quickly. This means I can be back to enjoying their cozy warmth in no time.In conclusion, the OCOOPA Rechargeable Hand Warmers have become an indispensable part of my winter routine. Their efficient heat output, long battery life, and versatile design make them a standout product. While a battery indicator would be a nice addition, it doesn't detract from their overall performance. These hand warmers are a fantastic investment for anyone looking to stay warm and comfortable during the colder months. I wholeheartedly recommend them!

Was a bit worried about the battery after reading some reviews as it seems some people got some duds, but all good here so far. Instructions say to use the low output cables provided and your own 2A USB charger plugs, which I did and everything charged fine. Took about 3hrs to charge to max from empty when they arrived. Would be nice if they came with a splitter cable so you only needed one plug, but I had 2 spare plugs so not a huge issue just a little cumbersome on space. Heaters worked great once charged. Very hot. Tried to leave them on max to see how long the battery would last, but that got too hot for me. I found Level one is fine for normal use. Although they noticeably do heating and cooling cycles so sometimes they feel much warmer than others. I really like the big size tho and the way you can curve your fingers around each unit. The 2 halves stick together if needed but with this big model that feels unnecessary to me, however individually the 2 heaters are great, even for larger hands. They are a little bulky in the pocket but no worse than a car fob and a bunch of keys. Got about 5 hrs out of the first use after several hrs on max to start. So battery life isn’t bad. Overall really happy. Very handy and easy to use and just a joy to be able to warm up cold hands in bitter winter temperatures. Will see how the battery holds up.

The product is really good, I've had other handwarmers in the past which are as durable but only a single unit so it doesnt hold enough heat to warm both your hands up at once. I saw some players using similar devices to these in a gaming tournament and when I saw the price I pulled the trigger. I've used them for a few hours now and they definitely keep both hands warm and are fun to fidget with as well. Doubling up as a power bank is a great idea but I've not used that functionality yet.The reason its not 5 stars, one of the halves of the devices button seems to have a fault, it requires a longer press than the other. One I can just tap the button with my finger and the heat setting will increase, the other this will not increase the setting and I have firmly press it in for it to register. At the moment this isn't a problem, however I am worried that with time it will degrade further and I will be unable to change the setting on this half.

Ideas size and heat levels good. Easy to operate and a simple pus button to do so. Robust in how the warmers are built. Come with a box taht allows stoarge when not in use. Only down side, but it is minor, is USB charging leads could be longer?

There seems to be a charging Issue with my hand warmers, I bought them because I wanted something easy to recharge with a usb c charger. Unfortunately these can only be charged with certain low input cables/plugs. I have tested these on charge with a few of my usb c cables/plugs and they only seen to charge on a few selected ones which make them quite awkward.I paid more for these specific hand warmers than lots of other ones I have seen on Amazon as I wanted the feature of being able to charge them in any of my phone chargers, and I'm not able to do that.As actual hand warmers though they are excellent and get very warm.

These are exceptional hand warmers that provide four levels of heat over a prolonged period of time and are perfect in treating my Raynaud's Syndrome in the colder months.I had one minor issue with one hand warmer after a reasonable amount of use and Gary at Ocoopa dealts with my issue swiftly and politely being incredibly apologetic, welcome to feedback, and sorted a replacement within a matter of days. Exceptional customer service!I have also purchased some smaller hand warmers from the same brand for elderly relatives which have also received significantly positive feedback and they also find the product easy to use independently.

I’ve had these for years now and love them. I get hives from the cold, and these are truly so good for keeping my fingers warm and toasty! Also they rarely need recharging so that’s a bonus!

Works great! Note that you need to use the provided cables to charge. Doesn’t seem to charge with other USB C cables.

Prima product. Voldoet aan verwachting

I liked it very much. I tend to get cold rather quickly so I bought it in the hopes of getting through winter easily this time around and I did. I think having them separate is not only good to put them in pockets but to share them with friends. Wich is a nice point.At the beginning i thought it wouldn't heat up that much, but it heats up to the point of almost burning me hand a couple of times, wich it's good cause I really can't stand the winter.The only thing is that the cable to charge them is a bit short. But luckily i have sockets very close to the ground so it wasnt a problem for me, but I do see people having problems with them. Overall will recommend just paying a bit more for a very good quality product.

Ce chaufferette est le sauveur de l'hiver, chauffe très bien et rapidement

Se soffri il freddo alle mani o passi molto tempo all’aperto durante l’inverno, questo è uno di quei prodotti che dopo aver acquistato ti chiedi come hai fatto a farne a meno.Lo dico dopo aver testato praticamente ogni tecnologia disponibile negli anni:* scaldamani a benzina Zippo* modelli a carbonella* bustine chimiche monouso* scaldamani a cristallizzazione con clip metallica* primi modelli elettrici ricaricabiliTutti avevano qualche limite importante: poca praticità, autonomia ridotta, calore discontinuo oppure procedure scomode per il riutilizzo.Con questo OCOOPA ho finalmente trovato la soluzione definitiva.⸻🔥 Utilizzato sul campo durante le osservazioni astronomicheEssendo un astrofilo, trascorro spesso intere notti in montagna ad osservare il cielo con telescopi e strumentazione ottica.Chi pratica questa attività sa bene che il problema non è solo il freddo, ma il fatto che spesso bisogna togliere i guanti per effettuare regolazioni precise su:* telescopi* oculari* montature* fotocamere astronomicheDopo qualche ora capita facilmente di perdere sensibilità alle dita.È proprio in queste situazioni che questo scaldamani ha fatto la differenza.Quando le mani diventano rigide e fredde basta impugnarlo per pochi minuti per ritrovare rapidamente comfort e sensibilità.⸻🧲 Il sistema magnetico è genialeLa caratteristica che preferisco è che può essere utilizzato:* come unico scaldamani più grande* oppure separato in due unità indipendentiNella vita quotidiana tengo spesso una metà in ogni tasca del giubbotto.In questo modo quando infilo le mani in tasca trovo sempre una piacevole fonte di calore.⸻💻 Utilissimo anche in casaPensavo di usarlo solo durante le uscite astronomiche.In realtà oggi lo utilizzo continuamente anche in città.Ad esempio durante l’inverno, quando lavoro al PC per molte ore, mi capita spesso di avere la mano del mouse fredda.In questi casi lo accendo per qualche minuto e il comfort migliora immediatamente.⸻🔋 Due scaldamani e due power bankAltro enorme vantaggio:non è solo uno scaldamani.Ogni metà integra una batteria ricaricabile e può funzionare come power bank.Questo significa che nel mio EDC (Every Day Carry) svolge una doppia funzione:* riscaldamento* alimentazione di emergenza per smartphone e dispositivi USBDi fatto ci si porta dietro due mini power bank sempre pronti all’uso.⸻🛠️ Materiali di qualitàLa scocca metallica è eccellente.Una volta raggiunta la temperatura:* accumula bene il calore* lo trasmette in modo uniforme* restituisce una sensazione premium rispetto ai classici modelli in plastica⸻⚠️ Un consiglio pratico per l’uso in montagnaL’unico aspetto da conoscere non è un difetto del prodotto ma una semplice conseguenza della fisica.Quando la temperatura esterna si avvicina allo zero o scende sotto lo zero, il dispositivo disperde inevitabilmente più calore nell’ambiente.In queste condizioni potrebbe sembrare meno caldo rispetto a quando viene utilizzato in città.Il trucco è semplicissimo:👉 tenerlo nelle tasche del giubbotto tra un utilizzo e l’altro.In questo modo si riduce la dispersione termica e il calore viene sfruttato quasi interamente per riscaldare le mani anziché l’aria circostante.⸻✅ PRO* Calore rapido e uniforme* Due unità separabili magneticamente* Ottimo sia all’aperto che in casa* Materiali metallici di qualità* Utilizzabile come doppio power bank* Dimensioni compatte e pratiche* Perfetto per escursioni, astronomia e attività invernali* Molto più efficace dei vecchi sistemi chimici o a combustione❌ CONTRO* Con temperature prossime allo zero il calore percepito diminuisce se lasciato esposto all’aria (normale dispersione termica)⸻🎯 Conclusioni👉 Compralo se:* soffri spesso il freddo alle mani* fai trekking, campeggio, fotografia o osservazioni astronomiche* lavori all’aperto durante l’inverno* vuoi uno scaldamani che sia anche un power bank di emergenza👉 Evitalo se:* vivi in zone dal clima mite e lo utilizzeresti raramenteDopo anni di prove con praticamente ogni tipologia di scaldamani esistente, questo è il primo che considero davvero completo. Oggi fa parte stabilmente del mio equipaggiamento quotidiano e delle mie trasferte astronomiche. Per me è uno di quei prodotti che meritano senza esitazioni 5 stelle su 5.

bought these for my wife who suffers cold fingers - she takes them power walking and it helps a lot
