2 Pack - USB-C Rechargeable Hand Warmers - 16 Hrs

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 pretty good so far, heat up quick and feel like they would keep hands warm when kept in jacket pockets for a day out. While the warmers are together, they are a bit hard to hold. I have fairly large hands and while I can hold them together, definitely easier to split and hold one in each hand. My biggest issue is that one side doesn't get as warm as the other side. Its slightly frustrating given I want my hands to both be warm but worst case I can swap which one I use to both hands. Battery life seems good but havent timed how long they work for. I'd assume a few hours? Definitely nice to have when outside in the winter, happy so far with them.

I started to look into hand warmers body warmers foot warmers since I need to be in a warehouse setting for 15 days in December. I got both this one and the mini one. the mini one heats up immediately and this one needs maybe one minute to fully heat up. when I first turn it on, I thought they might be defective and it's little odd that it wouldn't work if the mini one works so wonderfully. so I gave it some time to warm up and sure enough it works. I took them for a 60 min walk yesterday evening, weather was 45F and I only used the lowest settings and my hands were kept warm. really happy with this product and will get some as gifts.

I purchased for a movie outdoor event last night. Once is go cooler I turned the warmer on level one. They kept my hard at the perfect temperate. A friend got cold and I was able to hand her one to warm up. If they are perfect for a cool night, they will be perfection in December walking around at outdoor events.

I bought these because my hands are alway frozen. They work well, good heat, and I could charge my phone. I plan to take them hunting next week and it’s usually cold as heck. We will see. Good buy

These are very easy to use, good weight and they sit comfortably in your coat pocket. I loved the magnetic attachments! They’re very warm, maybe even too hot on the highest setting. They also look great…my only feedback is the slow recharge but other than that I’m impressed, so impressed that I did my first review.

Love these things, the shape is nice and small, so I don't worry about dropping. Lasts for 8 hours on setting 3, which is plenty hot. They do lose some heat as the battery gets low, but that's expected, and let's me know it's time to plug them in. Highly recommend!

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.
