Absolutely fantastic little gadgets! I’ve had hand warmers for a few years since developing secondary Reynauds and couldn’t be without them in winter. These are a big improvement on my old ones. They really do heat up in 3 seconds, it’s amazing! The hottest setting is boiling and probably too hot for me once I’ve warmed my white fingers up but that’s a bonus as it means the batteries will last longer. They only heat on one side but you can put them together to make one big one if you’d prefer. They fit nicely in gloves and come with a nice little bag to keep them in. The fact that you can charge them at the same time is a bonus. I’ve included a photo of the box with battery details etc. on it. These are going to be a lifesaver for me this winter…no more pain!!

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.

We live on extensive rural acreage within a great lakes snowbelt. Every winter we go through many pairs of bagged granular hand warmers. With our active outdoor life, the bags are sometimes damaged enough to leak contents and when Ziploc-stored to extend use, there’s no way to tell one bag from another or how much ‘heat life’ is left. So I tried the OCOOPA UT3 light rechargeable electric warmers. At first, I had problems understanding the very skimy User’s Manual – and I emailed OCOOPA customer service, asking for help understanding button function and operation. They responded promptly with detailed instruction well written. In the interim, I was able to comprehend operation after viewing a YouTube video review. My first field trial of the UT3 was in an unheated (below freezing) hunting blind, wearing gloves. I set the heat on ‘high’ (three red lights) and soon found it to be warmer than necessary. I switched to ‘medium’ heat, and found that too was more than I needed, despite the frosty atmosphere. The heaters actually kept my gloved hands perfectly warm on ‘low’ heat setting. Without the gloves, the ‘mid’ setting was enough. And I would assume that working with icy-gripped equipment (i.e. Snowblowing), the ‘high’ setting would work fine. Recharging (blinking blue light) and battery checking is easy. In sum, these hand warmers exceeded my expectations. They are far better (read: warmer, more durable, easily checked, rechargeable, inexpensive/use) than the granular-filled heaters. And the service response was clear and prompt. – The Duffian

Perfect for the upcoming winter! Long battery life and the magnet upgrade is very convenient compared to the last hand warmers I had!

Works well but battery doesn’t last as long as advertised . It does recharge quick and easy. Great size for the pockets and nice little straps for around your wrists. I use these for my 90 year old mom whose hands are always cold. They are priced cheap enough that we have three pairs so she’s never without. 😂She loves them.

I am absolutely thrilled with these OCOOPA 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.

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 noticed they didn’t heat to a fixed temperature and remain but instead they turn off and on to generate heat. So you feel them continually warm and cool in your hands.
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. I haven’t tested them for any longer duration . . . yet.
It’s nice they come with the dual charging cords, but they’re much too short for most locations where I would plug them in. I wish they were twice as long.
So, I’m very happy with them, especially at such a low price.
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 3 hours but we used them at a higher level the entire time. They are light and fit well in your hand.

カイロ、要る？？ってずっと思ってた。が、日常使いに大正解。
スノボ行く時ぐらいしか使わないし、普段手袋も使ってないけど、これ買ったら、あー、こんなに手が暖かいって幸せなんだなって思えた。
すぐあたたまるし、暑すぎない。ただ、両面じゃないからぽっかぽかになりたい人は注意。私にはちょうど良かった。
