AI Hand Warmers Rechargeable 2 Pack with Charging Case, 14000mAh Electric Hand Warmers, AI Smart Chips Safe Heat, Gifts for Christmas, Outdoor, Golf, Hunting, Camping Accessories

These are the best! I love to keep them in my pockets at work in the wintertime. Their design makes it easy to curl your hands around them. My hands get so cold and having them readily available is great. They're small enough that they don't weigh a lot, but they are powerful! I can only keep them at the lowest heat level because the other levels are too hot. I love that they shut off on their own and that the battery lasts a long time. I love them so much that I decided to buy the as stocking stuffers for Christmas! Worth the money!

These things get HOT. Bought them for my girlfriend who seems to think she lives in a meat cooler. They charge via USB, last many hours on high, and they really put out the heat. I can barely touch them on high. They're perfectly hand/pocket-sized, feel sturdy, and you get two for the price, so not overly expensive. She's happy with them, so I'm happy with them.

I work construction and I love these to warm my hands during winter size and fits is perfect for my hands battery life seems decent

Would give 5 stars but the high is VERY hot so please use caution. Love that these have a little charging dock unlike many that require multiple cords. They warm up fast and can be used inside gloves or between layers, just be mindful of the heat settings. Have not had long enough to determine how long the charge holds up but can report back. So far very pleased. Purchased a 2nd set for my mom with diabetes.

I am happy with this purchase. I work outside in the cold and these small palm sized handwarmers are easy to carry in my pocket, and easy to turn on for quick warming of hands. The low setting is sufficient for warming bare hands, and the higher settings work well through thin gloves. When turned on the handwarmers seem to turn on for a time and then shut off, to not burn your hand which is nice. But it turns back on again at a nice rate that you aren't waiting for them to heat up again. Very happy with my purchase. I'm curious if more expensive models have the ability to sense your hand temp and maintain a more constant warmth though. Regardless, I am very happy with this product.

These worked very well and, get pretty hot. the case charges them up when not in use these are perfect for winter weather

I just bought these and they already seem great! They work well and get warm very quickly. They came charged a little, but I elected to charge them fully before use. It didn't take too long for them to charge, and they use a USB C cord, so I could use my high speed charger for them! They are very easy to use and figure out, and are great for outdoor walks. I personally stuck them in my gloves for some warmth, and it worked great.

I bought these for my wife. She likes them a lot and uses them frequently.
