Wavmill Hand Warmers Rechargeable - 2 Pack Portable 5200mAh*2 Handwarmers - 360° Warming, 18Hrs Heating Time Pocket Heater - Great for Outdoors, Hunting, Hiking - Gifts for Men, Stocking Stuffers

I am a hockey coach and I spent a lot of time at the rink. I get cold and usually wear gloves while on the bench. Putting these in my pockets has been an improvement. Gloves caused issues but these are small enough for the pocket to give me warmth.I have yet to run out the battery while using so I am not sure how long they go but definitely more than I need which is usually a couple hours.They are very easy to use and charge. One button and USB C.

These are easy to hold, warm up quick, and I love the flat spot so they don’t roll everywhere.

These do get nice and warm and have 3 intensity settings, and they magnets in them on the flat sides, and they are made in pairs so they attract each other, one has the north pole facing out, the other has the south pole facing out, so you can stick them to each other. Not sure why you would want to do that...They do not heat in 360°, 360° would mean the heaters inside them go all the way around the cylinder and heat uniformly in all directions, these do not do that, they only heat the flat part, and that is all, since they have an aluminum body, the aluminum will eventually conduct all the way around, but only if you are leaving them sit on a counter or something, but even after pre-heating them like this, your hands will extract the heat as it is generated faster than it can go all the way around, so you will only feel it being warm on the flat side after about 5 seconds... but wait a minute.... what about those magnets??? hmmmm... if you stick them to each other with the magnets and turn them both on, now you can't hold the flat side... so your hand can't suck all the heat out of it faster than it makes it, and what do you know... if you do this, and hold them both in one hand, then YES, it's 360° heat, and THAT'S how they are meant to be used! you are NEVER supposed to touch the flat side, you are supposed to stick them together flat side to flat side and use the two together in one hand and buy another set for your other hand. Try it, they are WAY more comfortable and with more uniform heat if you stick the magnets to each other and hold them both in one hand.They come with USB-C charging cables, but not the power supplies, which is pretty typical for USB powered things, they say 5V@2A on them so any typical USB charger should work fine.They have 3 LEDs on top, they are blue while charging and green while warming. you need to press and hold the power button for a few seconds to turn them on, which is a good feature to prevent them coming on accidentally. They don't come with any kind of plug for the USB-C charging port, and from my experience with my phone, all kinds of pocket fluff gets into USB-C connectors, and then you can't get the plug all the way in, so to prevent that I got some USB-C plugs to keep the pocket fluff out of the connector.

I bought a different pair of hand warms before this one and they were larger for my hands so I returned them. Even though they worked fine they didn’t fit my hands so I bought this pair and they are perfect! I love them

Theses are great for winter activities. They charge fast fit in hand good. nice and comfortable made out of good material and really easy to use. Great price for a great product.

I use this for camping and very light weight and easy to fit in a pocket, also you are able to adjust the heat. This will be great for winter season. It takes a minute to warm up and keep your hand warm.

The Wavmill Hand Warmers - 5200mAh Portable Rechargeable Handwarmers - 360° Warmth works well, however the heating is a little uneven.I used a thermal tester on the hand warmer. There's a flat portion that has the highest temperature, however it is not spread evenly throughout the cylinder. The highest temperature I could read on the third setting was 122 - it lists on the product listing page as 131. I tested it inside a home, outside could be different. On each setting the temperature difference from the flat portion to the remaining part of the cylinder was approximately minus 5° to 7° difference.The flat portion of the cylinder heats up within one minute. After about 5 minutes, the rest of the cylinder started to catch up with the flat portion and it was maybe a three to four degree difference. If it's really cold outside it might take 10-15 minutes for the rest to catch up. It is definitely 360° heating, but slightly uneven temperature when fully warmed up. Also when it's very cold outside it will cycle and cool down a little for about a minute and resume the high temperature within a couple minutes. It did this cycle about 4 or 5 times in a 3-hour period. I think this is to prevent it from overheating.When you power it off it cools down very quickly, which makes it nice to put it back in its carrying bag.I love that it's 360° and the size and shape of the cylinder shape makes it very easy to hold. It comes with two USB C cables which makes it easy to charge it in your vehicle.The power button and heat setting button I wish were a different color because it blends in and it makes it more difficult to see at night. It's good that you have to long press the power button to turn on otherwise you could accidentally have it on in the nice thick carrying bag that it comes with.I have tried other hand warmers including Hot Hands disposable - which have been my favorite because of the even warmth on both sides of your hands. I love the cylinder shape of this product and so for me it's the next best thing to disposable hand warmers and less expensive in the long run. I found that on level one or two it is more than sufficient to keep my hands warm. I keep the flat portion that has the highest temperature around my fingers since that tends to be the coldest.I would recommend this set of hand warmers because I think at this price point, I doubt any of them sold on Amazon are going to have completely even temperature throughout even if you spend a lot more.Despite its small deficits, I still gave this hand warmer four stars because it does overall work well, it is rechargeable, the cylinder shape is really conducive to keeping your hands warm and the price is very fair for the quality.

These lil guys work great. Easy to charge, keep with you until you need them and then with the click of a button your hands will be warm in seconds. Just in time for winter jogs. 🙂
