coldSky Hand Warmers Rechargeable 2 Pack, Magnetic Electric Hand Warmer with Digital Display, Reusable Handwarmers Heat Up to 140℉, Portable Pocket Heater Warm Gift for Outdoors, Camping, Hunting

I got these to stay warm at work (It get very cold helping people at the drive thru window all day). They are worth every penny. I bought every color. My coworkers saw on the counter and now they raid my pockets looking for these warmers.The batteries last all day if set on low. Heads up... unless you live in the arctic, the high setting WILL burn you. Low is a great setting even in temperatures in the teens

I've been putting the Hand Warmers Rechargeable 2 Pack to good use through the cool fall mornings and found them to be just right for casual use as I head out to my commute every day. Great magnetic design-that makes it easy to slip them in my pocket and keep my hands warm without fuss. I set them to medium mostly, and for this temperature-chilly but not freezing-it's just right. The battery will last with no problem through my morning and will recharge fast enough for the next day. It's just about small enough and comfortable to wear on the go, especially now with the crisp mornings in autumn.

I go hunting every year but I e yet to adjust to the cold weather. Before I would just use the bag hand warmers you get at some gas stations but now. These are all I need.Easy to use, and they stay warm for hours.The battery has lasted me roughly 4 hours on the middle.

it seems as though people may be testing these right out of the box indoors. There seem to be a lot of complaints about them getting too hot to hold. This is the case when you put them on the highest settings inside. However, I just tested these out in very cold weather. these things are perfect. The heat is outstanding and will even penetrate thin gloves. I have even used them to warm up by rubbing them up and down on my legs. and works like a dream. Highly recommend these I give them five stars.Battery length is completely related to the temperature setting.(YMMV) from what I can tell on the highest setting, you’ll probably get close to an hour to an hour and a half of use.These things would be a great gift for this Christmas. I keep them in the pocket of my winter jacket. They are a lifesaver. Would be perfect for outdoor and stadium events.Stay warm out there people! 😃———UPDATE———Some folks are asking if these can charge a device. I tried with no luck.

Works great, the o my thing is they need to be recharged after an hour or so

We have multiple sets of these hand warmers and love them. They do a great job of keeping your hands warm.

Bought these to replace single use handwarmers for myself (an adult) and my two kids (6 and 8). They fit nicely into both adult and kid mittens. It is nice that there are 3 heat settings. We do the middle setting. They keeps the kids hands warm and the hottest setting is really warm. You can get 2 days of snowboarding on the mountain out of 1 charge. I love the cord that comes with so you can charge two at a time. Love these and they have replaced single use handwarmers!

The hand warmers were a little difficult to figure out at first, but once you got it, it was never a comfortable warming of the hands. It was either on or off basically although you can adjust the temperatures they got so so hot you could only hold them for a second They weren’t something you could hold on to or keeping your hands long at all, even on the lowest setting. Adjustable no not really hot definitely..
