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.

Great product! Compact, and generate a lot of heat, even on the first setting of three. Easily fit inside gloves, mittens or pockets.

These little hand warmers are impressive.
Pros:
They are small and lightweight, and are easy to slide in your gloves without an extreme hindrance on hand movement (I use them on the knuckle side while riding).
They are inexpensive, magnetic, include a lanyard hook/lanyard to hang from wrist when not in use, and the battery last for quite a while. (4 hours on medium and only lost one bar of battery – roughly 33%.)
The heat output is much better than I expected for the size. The highest setting will burn a little on bare skin. (I usually run it on medium for about 20 minutes and then low to maintain the heat.)
Cons: The power button is on top, next to the heat plate, and you hit it while using the hand warmers. (This usually results in increasing the heat setting.) The texture of the hand warmer should have been grippy instead of a smooth plastic, as they slide around A LOT.

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.

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

These are great. They heat up quickly. The charge lasts about 4 hours on medium and about 2 on high. I find myself not getting as cold whole body when i use them. I take and use them every week at the hockey rink.
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.

This little device helped me tremendously during a long three day backpacking. It helped me stay warm at night. It kept running a whole night and a half. It is also easy to recharge. Fits perfectly in your palm as you sleep. They can get pretty warm, so I did wear gloves while I held onto them.

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。
