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.

Have had mine since January 2023, now it's December 2025. I mainly used it for about 2-3 months out of the year and they have worked great! They get hot enough for me. They are a little slippery if you plan on putting them in your pocket. Also, mine did just start having issues charging but I think it's because I would leave them for months without use since I didn't need them every month. Still, not bad for the price and for the length of time that they've worked for.

Hand warmers were the perfect thing after a 30 minute ride to work in 31 degree weather - removing gloves taking off helmet - nice hand warmers like these do the trick and the heat lasts - portable- can even be used as power source

I play rec football year round, including winter, and keeping my hands warm so I can actually catch a ball is pretty key. On really cold days, vinyl gloves under the receiver gloves just isn't enough. One of my teammates got these and showed me his set - in 20 degree (F) weather with two layers of gloves on, they immediately warmed up my hands. So after the game I ordered my own set. I had a chance to use them last week and yeah, definitely keep the cold at bay while I was holding them. I didn't give all five stars for a few reasons. First thing I noticed is charging. They apparently messed something up with USB-C because power delivery adapters just don't work (C to C cables). Apparently only A to C chargers will charge these. Kinda annoying since most of my chargers are C to C now. Second thing is ergonomics - they're either too big or too small for my whole hand - if I press the curved part in my palm my fingers end up not getting warm, and if I rotate the device so my fingers are over the curved area it bites into my palm. I can deal but it's a little frustrating. However, they did their job and stayed warm in subfreezing temps for two and a half hours, and probably would have kept going - after the game I was at about 50% charge. I kept them in a hoodie pocket so they warmed up extra quick and used them on the ride home to keep my hands warm until the car heater kicked in.

Got these for my kids. They love them. Charge holds forever and the heat setting is great for bare hands or full blast for when wearing gloves. The magnetic part makes it easy to store and don't have to dig for two separate pieces. Conclusion: Yes, good buy!!

These hand warmers are small enough that I can hold them easily (I have a fairly small hand at 5'1"). They feel warm immediately. But do take a few minutes to fully warm up. There are 4 levels of heat setting and the highest is almost "hot". I find the most effective use is to place them in a pocket and put my hand in with them. It is my fingers tip that get cold and simply wrapping the hand around them is okay. But in the pocket is awesome! I have recharged them before going a full 16 hours...but they absolutely last more than 10 hours by my use.

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.

Very effective and last a good amount of time. Shame you don’t get a cable to charge them both together

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

Si, calienta muy bien y carga el celular sin problemas y algo rápido

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.
