AI Hand Warmers Rechargeable: Magnetic 2 in 1 Electric Hand Warmers with USB Charging, Portable Reusable Pocket Heater, Men Women Gifts for Outdoors, Golfing, Hiking, Skiing, Hunting

These have worked great over the winter. My son loads cargo at the airport and is outside in wide open areas where the winter wind can drive the temperature down, and these hand warmers easily get him through a couple shifts, important because flight schedules can change frequently. I'll order some more for camping. Thus far a very good product.

These work great, The battery lasts longer than it's supposed to, I used these to keep my hands warm at work perfect size they fit right in my work gloves and stayed out of the way and did not interfere with work. But inevitably ended up giving them to a homeless person who honestly did not even have a coat and the last time I saw him he still had them and said he would not give them up for anything

Heat up nicely, great battery life, useful.

these rechargeable hand warmers have been a life saver this winter. they heat up SO FAST. and they get REALLY hot but they’re perfect for holding when you’re wearing cheap gloves and they help warm you up super fast. perfect size for my hands. they also last so long inbetween charges. i’m very pleased with this purchase. i’m a fulltime dog walker and truly these things saved my fingers!

I got these before my family and I headed to an outdoor event in the winter. They were perfect to have in my pocket! My only issue was that they did get pretty warm to touch directly, but if you have on a glove or if you wrap it in a little fabric it was fine. I liked that they stick together when not in use. Easy to store and carry.

These were a gift and they couldn’t be more perfect! I work in an ER which is always cold. These helped me warm my hands so I could use them!!

These work great. I bought them for a trip to the New Hampshire, specifically to visit the Ice Castles and the top of Mt. Cannon. At 4 degrees, these kept my hands toasty inside my pockets. I kept them set on the low setting because medium and hot are VERY hot.The batteries, once charged, last a long time— more than 5 hours.

I might have gotten a wonky pair but holy cow are these things ever hot. One didn't want to fully charge but it kept up with the other heatwise. The magnetic feature is great and they seemed to be substantial. I was going to return them but have to not only got to UPS, but get a box from them and label. I will donate.
