CAKOSSYLatest 2S Fast Heating Hand Warmers Rechargeable, 5200mAh Portable Electric Hand Warmer USB Power Bank,Reusable Pocket Hand Heater for Winter Outdoor Sports, 2022 Best Warm Gifts for Women Men

After roughly a week of use:This hand warmer fits nicely in your hand and does a quick job in heating up. It heats up and then pauses, reheating whenever it hits a certain temperature threshold.I think in optimal conditions would it last 8 hours. However, I get maybe 5.5 hours on the lowest setting with consistent ambient temperatures of 66 Fahrenheit. Then it dies when I needed it for that extra time, which is instead spent on the charger.

If you're thinking of purchasing for your significant other, go ahead. I purchased this for my husband for night's he's out plowing snow or as a carpenter working in the cold. They are great to keep in there pocket's and put a little blood back in their fingers! You might want 2!!

It does the job. If fits in the palm, not too hot on low, and last 5+ hours on low. It’s my first day enjoying it. Hope it lasts a bit.

This hand warmer does a good job of keeping one's hand warm in the temperatures that we experience in the Wisconsin winter. It charges well (I always charge it overnight), and lasts at least through a typical 2-hour walk, set on the lowest or second setting (I haven't tried the warmest setting). My chief complaint is that the lack of any ridges on the hand warmer makes it very slippery and very easy to drop, especially when one is holding the panoply of winter gear that is necessary in winter. I dropped this at least 5 times during the winter. When dropped, clear dents and nicks appear on the surface. There is also the fear that dropping it might in some way rupture the battery, which would be very bad. But all in all, I consider this a good purchase and recommend it.

I bought 2 of these to use for massage in place of hot stones. They heat up very well, are easy to figure out how to use, and though I am not using them as hand warmers, I find these to be a good product.

I love this product, I’m a hockey mom and after seeing a fellow parent with one at the rink I thought what a great idea I need to try it. I bought a bunch as gifts for family members for Christmas and we all love it! It’s great for the ice rink or any time you are somewhere cold. My parents are always cold at home and they love it too. I love that it has three levels of heat. The easy usb recharge is nice and easy for everyone! I should have bought two when I originally bought them, one for each hand! I recommend this to everyone!

Got this for my husband as where he works it can get pretty chilly at night. This warmer does an excellent job heating up. He really likes the fact it is easy to operate with a simple push of a button on the side. It also shows on top how much battery life it has by the bars. For example, there's 3 bars that light up blue, when fully charged all 3 are light solid. Charging is simple you use a type c cord which was nice because we already use those for our phones you get a cord with this as well. Overall, very nice and fits comfortably in your jacket.

I like this product! I love the red color! It heats up on both sides. Nice feeling, soft material. I had no idea it doubled as a power bank! When it's fully charged the warmer gets pretty HOT! My only complaint is that I wish the battery lasted longer...
