Thermal Hand Warmer

I am absolutely thrilled with these KOZY magnetic hand warmers! The design is so clever—two slim units that snap together magnetically or can be used separately. They heat up fast and evenly, and the three different heat settings let you choose exactly the right warmth. I was honestly surprised by how powerful they are for their size!

The rechargeable batteries last a long time, and they’re perfect for outdoor activities, hunting, or just staying cozy during cold weather. I love how lightweight and smooth they feel in my hands, and they slip right into my pockets with no problem. These are going to be my go-to hand warmers all winter long—and they’d make an amazing Christmas gift too.

My partner bought these hand warmers, and after using them, I knew I needed a set too. I ended up buying them for myself, my four kids, and their partners. My daughter and her partner, who work out in cold weather, and my three sons, who play baseball, all love them. They used to rely on disposable hand warmers, but these are a game-changer. The hand warmers are especially helpful for my youngest while playing baseball, keeping his hands warm when pitching or getting ready to bat. The battery life is impressive, and they charge quickly, even in the car. This product is perfect for anyone spending time in cold weather. It’s a one-time purchase, cost-effective, and great quality. The different colors were a nice touch for my boys, and we’ll definitely buy again when needed.

Just make sure that you know there are three settings for these warmers. They work great but my granddaughters said they get too hot. Once I told them there were three settings, they are happy with them. I enjoy being able to keep my hands and feet warm. They are easy to use, seem to be durable and I like the oval design which fits into my gloves for a while and I put them in my shoes before I put them on to warm them up on a cold day. You can see the settings easily and they’re not too bright so pay attention for your settings and then turn off when you’re done. I recommend these for anyone that has cold hands year round like I do.

These work much better than I expected. They fit well into my palm and kept my hands warm even though it only heats on the top side. I found the level 1 and 2 settings good against my bare skin but the level 3 was too warm.

I first tried testing how well they function by only using one of them on an hour walk when it was 48°F. Then I measured the temperature of each device using an infrared temperature meter. I found there was no degredation in performance after an hour as the both measure the same.

So, I'm very happy with them, especially at such a low price.

Wife and daughter used these while we were hunting in October. Battery life was great. Used them on and off and lasted a day and a half. Heat up super quick and get pretty hot. We have had others in the past that were pretty junk. But these are awesome. They charged up pretty quick off the 12volt plug for the side by side. Way better than any of the little disposable packet hand warmers you can buy.

These work great! I took them to a tailgate on a cold morning and they warmed up my hands quickly and everyone wanted to try them. The adjustable heating levels is really nice and the highest level is almost too hot. The magnetic feature is wonderful so they don't get lost. The battery life was about 4 hours but we used them at a highest level the entire time. They are light and fit well in your hand.
