I bought these hand warmers for my oldest daughter as a Christmas gift, and she absolutely loves them! They charge quickly using the included Type-C USB cable and hold their charge for hours, which is perfect for outdoor activities or just staying cozy on a cold day. The three heat settings are a great feature—they warm up quickly and stay consistently hot without overheating. Overall, these are a practical and thoughtful gift, and I would highly recommend them to anyone looking for a reliable hand warmer!

They get nice and hot. Fit in pockets and gloves. Bonus that they also double as chargers. Would by again for fall camping.

I moved to Canada and these were a life saver! I recommended them to all my friends. I walk a lot and my hands always get so cold. I find gloves very annoying as I have to keep taking them on and off and they don't really keep my hands warm either. I keep these in my coat pocket on the lowest setting and that's enough to warm my hands. At first i thought they didn't heat up much but in my insulated coat pocket the heat was kept in. Also you don't want it to get too hot or it'll burn your hand. These were great! If i needed to keep my hands out of my pocket for long then i would up the heat setting but that was rare. The battery life was good. I can't say i truly tested the battery life because i would charge them every 2-3 uses before they died on me. My only criticism is they only provide one cable so you can only charge them one at a time but i thankfully have many type C cables so this wasn't an issue for me.

They were good while it lasted. Even though one did not last for the winter season, they worked well for my hands while it did. It stopped charging as written in other reviews. I'm thinking one was defective as the charging light was not too bright when received. Would love to buy another set but maybe might have to settle for another brand and hope for the best.

Preface: I got these for my girlfriend who has trouble remembering to charge her devices. She uses them year-round as a power bank to recharge her devices, AS WELL as to keep her hands warm. They work beautifully, with different heat levels to suit your mood. My gf says that minimum to medium heat is ample to keep her hands warm on even the coldest days. Though they DO discharge more rapidly than we would like, as we occasionally go for hours-long strolls.These electric hand warmers are absolutely perfect for people who are sensitive to the cold and like to walk around with their hands in their pockets. Not ideal for any activity requiring you to use your hands. Though they are perfect in my opinion, the gf has minor gripes so I give this product 4/5⭐

Pretty happy with these hand warmers! They've been surprisingly very convenient when I'm feeling cold / chilly. Not only do they keep my hands toasty warm, but the fact that they also double as power banks is a plus. The 8000mAh capacity ensures I have plenty of juice to charge my devices on the go. Plus, the compact design fits easily in my pockets or purse. These hand warmers have become an essential part of my "everywhere I go bag", and I highly recommend them to anyone looking for a versatile and reliable solution to stay warm and connected.

Overall the design makes perfect sense- a cylindrical warmer allows for your whole palm to get warmth and hold on conveniently. The nice soft carrying case was a nice touch, and it comes with straps for each warmer.Charging from out of the box was relatively fast before being ready to go- maybe like 3 hours since I had to charge each warmer one at a time. It does comes with 2 charging cables so you can charge both simultaneously if you have the ports to do so.My only complaint is that this thing is a bit too warm at the high setting. It gets warm pretty quickly, like under a minute, and by 2 minutes it's already at it's warmest. For really cold weather, this would be perfect, but for like a chilly spring night, it's a bit too warm for me. I guess I am nitpicking and technically you don't need something like this for spring weather, but it would have been nice to have like a heat seating that was just a little warm and not like a furnace.This will fit perfectly in my coat pockets, so I can't wait to try it in some proper winter weather.

I ordered these for my trip to Europe recently. I actually tested them out at work since I work outside before the trip and the weather is turning cooler. The hand warmers heat up very quickly in less than 30 seconds and you can adjust the heat setting. The heated part is only on the shiny side of the warmer as well. The charge on these is about 3-5 hours which isn't as long as disposable hand warmers. But I expected that due to its functionalities. Sometimes I'd forget to turn it off the save on battery life.They worked really as a back up charger too. I charged my phone but it won't fully charge your phone if you've been using it as a hand warmer. You'll maybe get up to 50% depending on the usage.The color is prettier that what I expected too. And the they're magnetic so the warmers stick together. They come with l white wristlets so you don't drop them, pouch to put them in, and a small cord for each warmer to charge.I bought these so I wouldn't have to keep buying disposable hand warmers. Overall it worked exactly how I expected it to.

First what I like a lot:The handwarmers themselves feel good in the hand, are not too heavy, seem well-made, are rechargeable and the 2 heat settings seem like they will work well for most situations. The lowest heat can be used with bare hands if needed, while the higher heat will work best when you are wearing gloves or mittens as it's too hot for bare skin for any length of time when fully heated. (Disclaimer: it's not yet brutally cold where I live so I have not tested these in extreme outdoor conditions yet. Also, I have not used them for more than an hour at a time, so I can't speak to the battery longevity.) I also like that they give you a small pouch to keep the handwarmers and chargers and instructions together when not in use.Now what needs improvement:1) The instructions! I read every word on the teeny tiny instruction sheet, some with the help of a magnifying glass. Not only are they hard to read, there are some things that I can't make heads nor tails of, such as something called the "protective function". After reading that section a couple of times, I just gave up and figured it was stuff I didn't need to know anyway. Also, the instructions state that they "are not waterproof to be used in rainy or snowing day". Hello? If you couldn't really use them on a snowy day, what good would they be? What they really mean to say is just don't submerge in water as it would short them out. This is a classic case of instructions being written by someone whose first language is not English, and they haven't bothered to have a true English speaker proof the copy.2) These come with little hanging ropes to attach to the units. This is actually a good idea, for storage or for attaching loosely to your wrists while using for a little extra insurance not to lose one on the trail. However, be warned that getting them attached to the units is NOT easy. There was no reference to these little ropes in the instructions other than mentioning them in the list of items included in the box. After looking everything over very closely, there was just one specific place where the ropes could attach, so I needed to thread the loop into this one little hole and push it through to a second little hole, then tie up the loop. Sounds simple BUT it wasn't. I pushed and pulled and worked on the first one for quite some time trying to get it to slide through to the second hole. Wouldn't go. Checked everything over again, kept trying, kept trying... finally went and found a safety pin and used it to "grab" the end of the loop and pull it through. Even that took a few tries and loosened the fibers on the loop in so doing, but I FINALLY got it. Now that I knew it would actually work, and how to do it, I turned to the second handwarmer and decided to time myself. It still took me 9 minutes to get the second rope onto the other handwarmer! The good news is that now I never need to deal with that again, so while it was very frustrating at the time, it was once and done. If I had to do that regularly these would have gone straight back. Most people are not are relentless as I am, and probably would have just thrown the loops away. There has to be a better way.3) The use of these is not exactly intuitive, as there is a light ring that flashes either green or blue when in use or when charging. Reading the instructions (which call these "breathing lights", whatever that means?), you learn that green is lower heat and blue is higher. And when charging, the green light just flashes until it's charged, then just stays green. I figured that out by trial and error since the instructions don't tell you that - they simply mention a red light to warn of low battery, which I have not seen yet given my light usage.Overall, the handwarmers themselves are very nice once you wade through the instructions and get the loops on and figure out how they actually work. Which is quite simple: on low, on high, off and charge is all there is to it. But don’t lose the instructions, because as I said, usage is not intuitive and you or another user might need to refer to them occasionally in future years.
