OCOOPA Hand Warmers: A Review

I am a runner and always have trouble keeping my hands warm with my mittens. I just recently purchased them to try them out and they worked. I place them inside my mittens. What I love the most is that you can adjust the level of heat.

These are perfect for teachers who have recess duty. I’ve used mine all week!

They get the job done. They get hot quick and warm your hands but they’re larger than expected and only heat on one side of each. Magnets holding them together were also weak and not ideal. Will probably stick to the left over disposable ones I have from last year

I've had a couple of electric hand warmers before but this one is just perfect as it can be detached to 2 parts and I can keep each hand warm in my jacket pockets. Also as nice is that each part can be used to charge other device, as long as you have the cable to do so. I've been keeping it in my jacket pocket for now, until it needs to be charged up again.

I've been using OCOOPA hand warmers for a few years now. I've decided to pick up a third set for an off grid camping hunting trip I'll be on. OCOOPA products have been a game changer for me. My hands use to get so numb in a matter of minutes whether I was wearing gloves or not that I could not spend more than 5 minutes outdoors at times. I use them at work as well to keep my hands functioning while working with small connectors and wires. Using them as a battery bank is a bonus function especially when traveling.

These are very very inconsistent. I had them on level 2, and it wasn’t quite warm enough for the rink so I raised to level 3. It seemed to be ok for a bit but then they started to cool off. I raised it to level 4 but they didn’t get warmer. Eventually they heated to level 4 which was too much and I put it back to level 2. Once the heat was down to a 2, I put them in my pockets but a few minutes later they were burning hot (hotter than they should be on level 2, was more like level 4 on a level 2 setting). They got cool again, then burning hot, then cool again, then normal heat, then hot again, then cool, they just kept changing on their own. When they cooled again, I tried level 4 again, but it barely warmed up and the temp was colder than level 2. These were fully charged before testing them. I thought they would be great for youth hockey games at an ice rink but they are too pricy for something that doesn’t work properly. The inconsistent temperature is also dangerous to have it on a low setting and have them get so unexpectedly hot that it hurts.
