OCOOPA Hand Warmers Rechargeable 2 Pack, Magnetic Electric Handwarmer, 4 Levels Heat Up to 136℉, USB-C Portable Charger 10000mAh, Raynauds, Golf, Tech Gifts for Men, UT2s(MagTwins)

I used this in ny winter. Definitely worth it if you walking in and out in the city

These are great as pocket warmers. You should stick them inside of things that you want to warm up.If you're like me and the backs of your hands get cold and are more of a priority than the palms of your hands, this type of warmer might not be the best fit. I didn't know that about myself until I got these.They pack away very neatly into a bag and are easy to charge. If this is exactly what you're looking for, then I would wholeheartedly recommend this item! I still keep these around in case I want to warm up a pocket or shoes or anything else that these can fit inside.If you're a cold-natured person and your discomfort is mostly from the backs of your hands being frigid, this form factor is not very convenient and I would suggest heated gloves or a more malleable, flexible heat pack that can more comfortably conform to the shape of the back of your hand :)

I was super surprised at how well this product works. It does what it's supposed to and what the product detail says. You can't go wrong with this product and I would buy again

These are very nice to keep my cold hands warm. They don’t fit comfortably though in my hands as I wish they did. They’re a little too big. But they do work.

Has a long battery life thought maybe not to the exact capacity as described. Heats up quickly and keeps hands warm.

Really good and easy to use. Saved me from winter

I do like these hand warmers, even with the 3-star review. The size is perfect to keep in my coat pocket and the shape is helpful to conserve heat with my hand wrapped around it. Level 2 is enough heat to keep my hands warm on calm, ~20-degree days with no wind.So why the average rating? There is no way these things will last the full 8 hours advertised, especially on colder days. I have never gotten more than 3 hours, max, on heat level 2, and I doubt the lowest heat level would be warm enough for anything approaching a polar vortex during a Chicago winter. Also, they take FOREVER to charge, so if you forget to charge them overnight, you're out of luck in the morning. That said, they are good for a couple of hours of birdwatching, which is what I use them for, but if you're going to be out all day, you may want to consider a different product.
