Keiyaloe Rechargeable Hand Warmers, 5200mAh Electric Hand Warmer and Power Bank, Portable Hand Warmers for Outdoor Sports, Best Valentines Gift for Men and Wowen in Cold Winter

I got this for my mom to go out in winter. It is very useful for her since she goes out a lot. It can charge her phone 2-3 times and make her hand warm by press the button and hold. The warmer has 3 level of warm. It has the red lights to let you known what level are you in. It usually get warm very soon. It is the best warmer that you should get in winter!

I am a person with cold hands and feet. Glad I bought this one before the severe winter comes. Size is handy, just palm-sized, easy to put in a small purse. One full charge can work for around 2 hours. Quality looks good and functions as a power bank is a bonus for me, under the emergency case. Overall, no complains and happy with my purchase.

So as small as this thing is I figured there was no way it would work any good. Boy, was I surprised! This thing packs a punch! To top things off, it charged my phone, too! Great little purchase!

You'll be pleasantly surprised at how hot this thing gets even on the lowest setting. In fact, it can sometimes be too hot to handle when used in an already warm environment. In colder climates, the frigid air and your cold hands will be constantly sapping heat away from it, so it struggles to stay super hot, but it'll definitely stay warm enough to keep your hands from numbing.How's battery life? It takes about 3-3.5 hours to charge on a quick charger, and it lasts about 4-5 hours on the lowest setting. It's a bit far from the "4-8 hours" listed in the Engrish manual, but still impressive.

My right hand always get cold in colder weather so I came upon this hand warmer. Its smaller and lighter than I thought (but that's even better since I don't wanna carry around some big heavy thing). It was mentioned to be the size of a phone but since I have iphone 8 plus, I was imagining that size. It also functions as a charger for my phone (that's a plus!). I have tried charging my phone and it works pretty well. The battery also seem to last pretty long; I have yet to try the hotter temps on the warmer since the smallest is warm enough for me right now. Overall, great product!

I tend to get cold hands. Initially, I thought this would be too small (I have large hands), but it gets so warm that it isn't an issue. It also fits nicely into a pocket. I haven't tested it for lasting power, but I haven't had to. It also didn't have instructions, but it was fairly intuitive to figure out how to change settings.

I have small hands but this warmer has just the right size!! it's pretty warm even just the first level and it can last for hours! Will purchase one more for my friends as her Thanksgiving gift !

I bought this for my son who rides the city bus to get to high school during the week. He has a half mile walk and then often waits up to half an hour for the bus to arrive. In the cold, Wisconsin winter, of which we are now entering, this hadn warmer helps keep him warm. He usually charges it at his desk at school - yes, they have USB chargers for student desks now, and has the warmer ready for the ride home. He loves the simplicity, just plug it in and then hit a button to choose low or high heat. On days he forgets to charge, it has not let him down so the charge keeps the heater going for at least a couple hours on high heat and stays in stand-by mode for at least 48 hours. I'm sure it will last longer than that, just haven't tried it.
