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

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.

So far so good with these; definitely heat up well and definitely warm up my hands. The highest setting is really warm, sometimes would say verging on hot. The mid setting it is enough to keep the cold at bay and my hands are very thankful for these little wonders. One of the warmers seems to take longer to charge than the other, bit of a pain but not enough of an issue to make me drop any points. They do last for a very long time, haven't timed it though. Also, even when I didn't need to use them for a while and they still had a full charge on them, was great that I didn't have to recharge to use them when I really needed them. Nice little bag provided to store them in stops them getting scratched and keeps them safe. For the price these are definitely worth it. Hopefully these will last a while, only time will tell.

Despite showing a 50% battery level on arrival, these units barely worked and I actually started a return. My partner convinced me to give them another go and after a full recharge, performance was completely different and much better. Once properly charged, the OCOOPA Rechargeable Hand Warmers are genuinely warm and effective. They get properly toasty (though not quite as fast as advertised) and provide consistent, comfortable heat. Real-world use: On a medium-length dog walk, they provided excellent relief from Raynaud’s Phenomenon, keeping my hands warm and preventing numbness from starting at all. That is the main reason I am now very happy with (and keeping) them. What’s good: Strong, steady heat once fully charged Very effective for Raynaud’s-related discomfort Solid, well-made build quality Comfortable to hold and use outdoors What could be better: Heat-up time is slower than advertised Magnetic connection is weak — they can separate in a pocket or bag Supplied with two separate USB cables rather than one split cable Bottom line: After a proper full charge, these are effective, well-built hand warmers that genuinely help with cold sensitivity and Raynaud’s. One star deducted for the weak magnet and optimistic heat-up claims, but overall I would recommend them — just make sure you fully charge them before first use!!

I have a job that is (mostly) outside and gloves aren't always ideal. So after shopping about, I chose these. The heat is great, with different levels it means you can adjust to what you need. Battery on full whack doesn't last the longest but as I use one, then use the other it means I get a good amount of usage. They weigh more than I thought but I like the weight and the size is perfect to grip in my pocket. All in all, I'm happy and have been showing as many people as possible. Now if only I got commission...

Great heat given and insanely well built with 4 different heat setting and has a long battery lifespan great product will 100 percent recommend.

Overall not bad, not great. The highest heat setting (4) fluctuates; it seems to regulate its own heat by briefly turning off for 30-60 seconds, followed by heating back up to max again. This creates a very odd effect of it being cold in your hand, followed by very hot, followed by cold, repeating. The first 3 heat settings all feel almost the same to me, I always run on the highest level but as per above however its often not enough due to how it regulates the heat. It does get quite hot when it's actually working at the full temperature. As a power bank, it works great, I've actually used them to power my heated vest (5000mAH in each doesn't last long though). It charges up quite fast at 18w PD too according to my charger. The form factor is not great either; it could do with the sudden edge being rounded more, and I often find myself accidentally pressing the heat/light buttons on the bottom when I grip it. The buttons could do with being a lot smaller to prevent accidental presses from simply holding it. I'm not super impressed, but it's decent. Buy it on a sale. UPDATE: It has been 6 days and now one of the devices is barely heating up on the max setting.

These handwarmers are a lovely rose gold sort of colour. They magnetize together and fit into a drawstring pouch, which ‘handily’ fit nicely in your pocket. You charge them up and they can also be used to charge your phone, like a power bank - so multi use! There are four settings for different heat levels. They warm up nicely. I can’t wait to try them out properly when the weather turns colder!

Bom produto. Compacto e fácil de transportar. Traz dois cabos usb-c curtos e um saco de tecido para transporte.

El producto es muy bueno, la batería le dura bastante y se sienten cómodos en las manos. Lo usé por varios días en el mínimo dentro de una cobija cubriendo mis pies. El calor era suficiente para estar cómodo y la batería duró 10 horas sin problemas. Es importante tener en cuenta que son para dar un poco de confort y no se compara con un producto dedicado como guantes o abrigos calefactables. Mi recomendación es ponerlos en las bolsas del abrigo más interno que tengas y en el mínimo. Fue la manera en que pude sentir la temperatura más constante, más cómoda y por más tiempo. Cuando los sacas a la interperie o los manipulas, el controlador hace cosas raras en las que a veces pierde temperatura y gasta más batería para calentarse de nuevo. Los he usado muy pocos días como para saber sí funcionan a largo plazo. Son muy buena opción si no quieres usar los calentadores de cámara de combustión y los problemas que yo conlleva.
