Rechargeable Magnetic Hand Warmers 2-Pack – UL Certified Electric Pocket Heater, 3 Heat Settings, Ultra Slim, Portable Winter Hunting & Christmas Gift for Men, UT3 Lite

These work great for me as I have Raynaud's syndrome and these hand warmers let me be outside comfortably in colder temperatures. They heat up quickly and are easy to operate. Great compact size. The Ocoopa customer service is also very helpful, I had a small issue and they took care of it promptly and easily.

Subsistence farmer here in the PNW.Fantastic product!I do a lot of daily outside work in cold wet conditions that requires manual dexterity I haven’t been able to achieve with warm waterproof work gloves.I used to use disposable hand warmers, but I have always felt wasteful because once you open the package, that’s it. You can’t turn them off or really rejuvenate them. Plus they are an on-going expense. And if you can’t find any, you’re out of luck.These things are fantastic! I keep them in my jeans pockets when I’m outdoors. When my hands get cold, I dry them on a rag and shove them in my pockets and grab the warmers for a few minutes. I usually started at heat setting 2 and lower it to 1.What’s great is that they help keep my core warm which means my extremities stay warm longer. As long as I remember to turn them off when I come inside for breaks or to clean up (it’s very muddy here), they last all day. Charging is easy. They don’t come with a brick, but these days few chargers do. I do wish they charged a little faster, but as long as I manage my use (IOW, don’t leave them on when I don’t need them), I only charge them after my chores are done for the day. I love that they are magnetized and take up little space while charging.I like them so much that I bought a pair for my mail carrier and a pair for my mother whose arthritis gives her grief. They are both converts, too.Seriously, just shove them in your pockets on the first or second setting, and you’re good to go!

I’ve been using these OCOOPA hand warmers for a little while now, and overall I really like them. They definitely get hot — I’d guess close to the 125°F they advertise — and that temperature is perfect for actually warming your hands. As someone with mild Raynaud’s, the heat really does make a difference, and these offer quick relief when my fingers start to go cold.The downsides are mostly around practicality. The battery life is fine, but the charge time feels slow. When I run them on high, it seems like they take almost as long to recharge as they last. The included Y-shaped charging cable was a nice idea in theory, but one of the two output ends on mine didn’t work at all, so I ended up charging one side at a time anyway.OCOOPA’s model system could also be clearer. The numbers (3, 4, etc.) feel random — if the “4” is supposed to be better than the “3,” I really can’t tell how based on their descriptions. On top of that, the sizing isn’t consistent: some models list measurements in centimeters and others in inches. It makes comparison way harder than it should be. For larger hands, these are on the small side. They still help, but they don’t fill your palm the way I’d like.I also ordered another OCOOPA model with heat on both sides and I prefer that one. Its a nice feature that warms more evenly and works just as well overall. I’d recommend a 2-sided model if you’re deciding between the two. One major downside of both models is the size. Yes, small makes them portable and easy to fit in your pocket, but these do not work great for people with large hands.Still, the heat output and reliability make this a solid 4-star pick — great for cold hands and Raynaud’s, with room for improvement in design and charging.

Wow they heat up so fast! They came fully charged with wrist lanyards that can be attached, a charger with two on one end so both hand warmers can be charged at the same time, a storage bag and very limited instructions but it is easy to figure out and easy to use. They appear to be well made. They fit comfortably in the hands and are slim enough for smaller hands but I think they would work well for larger hands as well. They are magnetic so they stay together when you aren’t using them. I bought them due to arthritis and poor circulation and the warmth along with the slim design are a great benefit. I think they are a great value.

I love these hand warmers!I bought these just in time to use at my kids outdoor sports games this Fall. The charge lasts for at least 4 hours (I didn't time it but it made it through 2 youth football games and then some) The dual charging cord is a major plus, I use them both so charging at the same time is a big time saver and having the USB end makes it easy to charge in my vehicle if I need to.These are good quality and they work great. These warmers fit perfect in my palms. The heat range is just right, the lower setting feels like the disposable hot hands, I love that these can be much warmer. The box they come in is a nice touch also.I will be ordering more from Ocoopa, everyone would like a pair of their own now.
