Hand Warmers Rechargeable 2 Pack, Magnetic Electric Handwarmer, 16 Hrs Warmth 4 Levels Heat Up to 137℉, USB-C Portable Charger 5000mAh, Raynauds, Golf, Tech Gifts for Men, Union UT2s(MagTwins)

This product is really good. They charge fast, keep in mind you need to make sure the charger you use is a good one, to verify, one of the blue lights will turn green to indicate fast charging as label in the instructions (look at last picture for reference). I feel like most of the other reviews used a slower charging setup. I use my Google pixel 7 charger which is USB-C to USB-C. You can also use the cables provided but you need a good power box. The heat it provides is excellent, I live in Chicago so the weather is cold and these work great. I really like the fact that it can be on the highest heat setting and once I turn them off it takes seconds to cool down, pretty neat feature so I can store them away without risking heat damage to anything. I also like the ability to use these as a power bank, Great feature. I like that it also comes with 2 charging cables and a carry bag. Overall really solid product, great heat output with multiple heat setting and great additional features and it's not heavy. I would buy again. I recommend this product. Now on the downside.... First in foremost the instructions are terrible and can be updated. This version of handwarmers which are the gamer edition don't come with the dual USB-C, meaning I have to use 2 different chargers or charge one at a time which is just inconvenient.

Nice handwarmers. Heats up very quickly. Good value for the money. Length of battery life depends on what setting you have it on. Havnt quite figured of total run time based on setting but on low it made it through a 4 hour round of golf.

I recently purchased these rechargeable hand warmers for my husband, who spends a lot of time outdoors hunting in the cold, and they have been absolutely fantastic. **Ease of Charging**: These hand warmers are incredibly easy to charge. They come with a USB cable and can be quickly powered up using any standard USB port. The charging process is straightforward, and they hold their charge well. **Long-lasting**: One of the standout features is their impressive battery life. A full charge lasts for hours, which is perfect for long hunting trips. My husband doesn't have to worry about them running out of power in the middle of the day. **Effectiveness**: The hand warmers heat up quickly and provide consistent warmth. They are very effective at keeping hands warm, even in extremely cold conditions. My husband has found them invaluable during his hunting excursions. **Popular with Friends**: My husband was so impressed with these hand warmers that he ended up getting extra ones for his friends. They've all been raving about how much easier it is to endure the cold with these handy gadgets. **Overall Experience**: These rechargeable hand warmers have been a great investment. They're easy to charge, last a long time, and are highly effective. They've made cold hunting trips much more bearable for my husband and his friends. I highly recommend them to anyone needing reliable warmth in cold weather.

Based on information that I gathered from going down the online rabbit hole that is the answer to the question "what is the best rechargeable hand warmer," I settled these. I wanted to use them as glove warmers. When separated, each warmer is about the size of two disposable lighters, too big to go in a glove. This is why I only gave them four stars. They do get incredibly warm very quickly and I like to use them while I am at work to warm up my fingers. I have very cold-blooded hands, and even with fingerless gloves on my hands get chilled. These hand warmers get so warm on high that they will warm my hands through the gloves! The magnetic feature is a bit of a gimmick, but it does turn the warmers into one larger unit that will still heat while they are put together. It should also make it harder for me to lose one of the warmers. They charge as two separate pieces, which is not a big deal, but they came with two charging cords and only one single-outlet charger "brick." A dual-outlet charger brick would have been a much better option. I haven't used the power pack option to charge my phone, so I can't comment on how well they work for that purpose. Overall they are very good warmers, and the magnetic feature is surprisingly useful. I just wish that they were thin enough to fit inside a glove. They might just barely fit into a really large mitten. Wish I could give them five stars, but I can't use them for exactly what I wanted and I had to come up with a second charger brick in order to charge them both at the same time.

Probably the best hand warmer I have bought so far. Its lowest setting is not overwhelmingly hot, so you can have it on for a lot longer without getting burned. However, subsequent settings can get pretty hot. Its small form factor means I can store it in small pockets if I split up both halves.

Update edit 1/26 The seller reached out to me after my review offering to make things right. They offered to send me a replacement. Not only that, but they sent me an upgraded model to meet my needs (longer battery life & more heat) Not only that, but it was all at their expense. For that kind of value, I have to update the review to 5* ----- Previous review: I purchased another handwarmer from this company 5 years ago at about the same price. The only reason I give it 2* not 1* is the physical quality of the product is very good. Nice packaging and feels premium to the touch. However, the rest is downhill from there: 1- Heat is not good enough. Heat setting number 3 is the same heat as the lowest heat setting on the old one 2- Battery life is terrible Heat setting 2 (IMO the minimum) lasts about 2 hours only. Significantly less than advertised. My old handwarmer lasts more than double the duration on its lowest setting (which is significantly warmer) 3- It's a smaller than it looks If your hand size is average or above, you will not like the fit of this You will need to keep rotating it to heat either fingers or palm of your hands, not both. Overall, very disappointed that the product I purchased from them 5 years ago is so much better in many ways than their new product in 2025.

Works well. Charges and stays charged. Easy to use and good size. They get very warm.

Surprised by how good these are. They are nice and smooth with a decent size to fit in hand. They get warm enough to actually help keep my hands warm and with pain. I’m actually planning on using them with my massage therapy as the round side actually glides easily on skin and cloth and gets hot enough equal to a hot stone. While the charging takes a while to get a full charge it is well worth it and leaving it in a pocket keeps them warm. I love them and planning to get at least 2 more pairs. One for my girlfriend and another to use to keep in rotation when working on folks. I do recommend a better way to control the heat as once it is turned off the heat is immediately gone and getting it back takes some time so maybe a different material that retains heat but is still safe for skin contact would be best. Overall 4.5 out of 5. Highly recommend if you are just thinking about keeping your hands warm. And a good way to massage trouble spots along the arm, thigh, and back preferred with a small amount of cloth between then two. Update: just bought a new set for massage use only and compared the original one I bought with these new ones as I noticed they changed the material for the shell of the device to a bit more grainier but more heat retaining alloy. The new set is lighter and heats up faster than the original. I’ve also noticed the changing takes longer on the new ones but the time use on them are the same as before might be the ones I bought but still. This gives the device more heat to use all around and quicker at that but the material isn’t as smooth as the old material but the heating aspect is now a lot better. Again these things are perfect for hands and massages. While I’ll miss the weight it used to have(it’s like 5 grams or half an ounce difference in weight) I think these are perfect for winters and just heating use in general. A perfect stocking stuffer or white elephant gift or even just hey here’s a little something to keep those hands warm.

Ich bin super zufrieden mit dem Ocoopa Duo Handwärmer! Er liegt gut in der Hand, wird schnell warm und hält die Temperatur lange. Besonders praktisch sind die vier Heizstufen, so kann man die Wärme je nach Bedarf anpassen. Die Akkulaufzeit ist für unterwegs wirklich gut – ich nutze ihn beim Spaziergang, beim Winterspaziergang mit dem Hund oder beim Warten im Freien und bin immer wieder begeistert, wie zuverlässig er wärmt. Die Verarbeitung wirkt hochwertig und robust, und das kompakte Design passt problemlos in jede Jackentasche. Aufladen per USB-C ist unkompliziert, und der Warmhalteeffekt ist deutlich spürbar – selbst bei richtig kaltem Wetter. Für alle, die schnell kalte Hände bekommen, absolut empfehlenswert!

My wife loves using these to warm her fingers when I'm driving. Perfect size and stows away easily in her cup holder. Also great for when you don't have a heated steering wheel, to warm up after brushing off the snow from your vehicle! No issues with the battery life so far, we just plug it in after a week of using it for 20 minutes each day. The magnetic two piece design is well thought out, took no time at all to get used to splitting them and pressing the power button even with gloves on. And can even slip the pieces into the gloves so they're on the palm. Great buy!

For a guy who's hands always seem to get cold, this device is great. What's interesting is two days after receiving it the temperature in Montreal dropped to below 10c. I love this purchase.

No lo he usado demasiado porque la temperatura subió pero llego bien, venía bien empacado y todo funcionaba perfectamente Además es muy lindo con sus lucecitas

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!
