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.

I was cautiously optimistic when I bought these. I was hoping they'd be decent, but you never know what you're gonna get. But these have exceeded my expectations! I'm very pleased with them. They start to warm the instant I turn them on and they get hot. And my hands in the winter are always freezing so that's a good thing for me. The magnets that are in them to hold them together are pretty strong. And everything fits nicely in the provided carrying bag. I wasnt aware when I bought them that they are also power banks so that was a nice surprise as well. I highly recommend these!
