There are those clients who have Raynaud's or do hunting or work in the very cold degree. Check about the idea of using Ocoopa rechargeable hand warmer.
I bought Ocoopa hand warmer to just try out and see if my winters could be more bearable. This thing definitely does the trick. It heats up extremely quick, seconds, and packs a punch when it comes to heat. It also had a large battery to provide heat for several hours.
It has a cool feature that it is able to charge other devices from its battery.
My only complaint might be the durability. The runner edging seems like it might come off eventually. I'll update this review if it does have issues.
Great warmer though!

This little hand warmer battery charger combo is something that I don't know why hasn't been Invented before. It is absolutely perfect. That has the ability to charge my cellphone keep my hands warm and it's not so big and bulky that it's uncomfortable or frustrating to keep up with. It has an amazing heat, and works perfect if you turn it on and just slide in your pocket . The little strap to carry it the carrying case all are extras that you can use or not use totally up to you. If you find yourself in the market for a backup battery charger for your phone I would say you need to buy this period because why not have a hand warmer Built-in!

I have Raynaud's and in general get cold easily, so keeping my hands warm is a constant concern. I had to return a different brand because the warmth did not last long enough. I have two of these OCOOPA's, one for each pocket - I have played 9 holes golf in 40 degree weather, with the warmer set at the lowest heat level, putting my hands in my pockets or carrying the warmers in my hands while I pushed my cart, and had 2 dots of 3 battery left at the end. I am pretty confident they would last 18 holes as well.
Yes they are a bit heavy/bulky - read the description - but fit my hand just fine, and, honestly, if you get cold, a bit of bulk is no big deal. I have tried the hotties, but these are much much better - warmer and longer lasting. Hotties are good to slip in the boots though. I have also tried the lighter fluid warmers, which warm very well but are a hassle in comparison to a rechargeable - if you are hunting or camping without a power source, I would suggest Ocoopa hand warmer, of course.
Recharging does not take very long.I am very pleased and only wish I had bought them sooner.

I wanted something other than heated gloves and disposable warmers. I didn’t understand the purpose of these since the rest of your hand doesn’t go into a glove. But I’m a fan of different tech so I bought Ocoopa.
This is a first impression opinion having only tried one indoors.
Lanyard and pouch accessories included
Heats up quick and can get very hot to the touch
The pouch makes it comfortable when hot
You can use it as a heating rock not just for hands
Had to destroy the box to get it out. I like to preserve packaging to have the option to return.
Summary So Far:
Heated gloves can be mild at the highest setting. These are authentically HOT at the highest setting and toasty at the lowest.
I ordered another to have one in each hand/pocket.

I've had this OCOOPA Warmer/portable charger 10,000 mah model for almost a week now. It's kind of like a bar of soap. Not heavy either. Could fit in large winter gloves if you did not need to use your hands and be functional. I have not tried this myself though. I have 2 of these units. I will explain why I returned the other one at end.
My experience will be only using this as a hand warmer. I think this device will be perfect for what I need it for. I work out on an airport tarmac in the middle of the night and it gets very cold.
To test the ability of this unit I went through 4 straight days of continually using and charging cycles with excellent results. There are 3 heat settings. The highest setting in my opinion gets too hot to even handle the unit. 2nd setting would probably work best when it does get to below -0°F. But the 1st setting will stay nice and warm when you need to hold on to it. This thing heats up extremely fast. Less than a minute. I was thinking I would need to leave this thing on in my pocket all day hoping it would not die toward the end of my shift. Turning it on when needed is just as good. I had only one shift where I actually used it on my hands where it hovered around 32°F with misting raw rain & wind chill off the ocean. (In my opinion I doubt it is anywhere near waterproof or is water resistant so I would not expose to wet elements.) The usage time which is what I was worried about is just phenomenal. On the lowest setting I can get anywhere from 12 to 14 hrs. Just shy of advertised 15 hrs. On 2nd setting it's around 10 to 11 hrs. I did not test on highest setting because I don't think I will use that because it's just too hot. Charging takes roughly around 3 hrs. The 3 hours advertised by the company I assume does require a certain amperage from your charger. (Which they don't include.) (The USB C cable is included.) I do happen to have the newest Samsung 45w charger & 5 amp cable from my phone that's more than adequate to charge this in 3 hours. I don't know about older chargers with lower amperage/wattage & voltage. Now the 2nd unit I purchased heats up good like the first unit. The three settings work also like the other unit. But the battery time only lasted about 6 hrs on the lowest setting with the same continuous 4 day cycling test. Obviously there is a battery cell problem so I I'm returning that one.
I wrote this review because you should know that I did end up with one unit that worked very well and one that was obviously either used and repackaged or just defective. Since I can only attest to about one week of usage I don't have a longevity review. This unit is advertised to be using a newer lithium cell 21700 which I use in high power LED flashlights. These batteries are awesome. However I don't know how this type of battery will last long term in this application (built inside a unit to create "high" heat). Heat drastically shortens lifespan of lithium cells. For now it does what I need at a good price $$$. Time will tell.

I live in NY and it's not even mid October yet but it's so cold in the morning...
This gadget is so cool (actually so warm 😁) that it's a MUST-HAVE for me especially since I always carry a portable charger with me anyways.
This will be so handy since it's a hand warmer yet it can charge my phone if needed!
I already used it few days in the morning and I loved it! Both sides of the device gets warm very fast and starts keeping your hand warm immediately. It has 3 level of temperature setting and the surface is soft and comfortable to touch.
5 out of 5 stars. This is a must-have if you have to stay out in the cold for long time for any outdoor activity or travel. Highly recommended!

My wife suffers from Reynauds Syndrome which means some of her fingers are always white and cold. It’s especially problematic in the winter. This was a return to work gift that has a double purpose. It’s a mobile phone powerbank and handwarmer as well so a very useful device. The handwarmer function works very well. Infact in setting 3 it can be too hot! Not so hot as to burn but just shows how effective it is. Having a 10,000mAh charger means she can charge her mobile many times. Ideal for her handbag.

This little gadget is brilliant. It's super hot even on the lowest setting. I already have a previous version which is great and keeps my hands lovely and warm in winter. Bought this one for the luxury of one in each pocket. This new improved version has a bigger battery and really does get super hot. It took a few hours to charge from new but in use, stayed warm for many hours, even overnight on lowest setting. Recharged quite quickly after first use. It's a must have for me. A real pocketful of comfort on the coldest days walking the dog. Buy one, buy two! Worth it.

Still hunting, bird watching, and walking at 25 degrees - a sweet treat to have warm hands. Also a great foot warmer on a cold night.
I have two quick charge hand warmers, one for each hand or side pocket.
Only problem is the provided sack easily rips at the drawstring seem. Its not the cloth but the thread used to sew the seem that comes undone. Operating without the sack is OK at the lowest setting but not so at medium or higher as the unit becomes too hot. Its always the simple things that work for or against a product!

I ordered this rechargeable hand warmer because I live in NY and I have Rheumatoid Arthritis and the cold is not kind to my hands. My fingers often turn blue from being so cold and this thing is amazing. It’s so warm, I don’t even have to go past the first setting, and it heats up in like three seconds. It fits right in the palm of my hand, my hand is about three inches wide and 6 inches long and my fingers wrap around it perfectly. I ordered another one immediately to be able to have one in each hand. It’s a life saver for sure!

I love multi-functional devices and had to give the Ocoopa Hand Warmer/Power Bank a try. I purchased this item as a heated option for keeping my hands warm in temperatures under 40 degrees.
The hand warmers take about 3-4 hours to charge and it has a 10,000 mAh battery with an estimated run time of 15 hours. It offer heat levels from 95 degrees to 131 degrees. Let me tell you that the first setting is all you really need to stay warm. It gets hot in seconds, which is shocking when you first try it out. It reaches peak temps at about 90 seconds. It is plenty of heat for your hands and you may find yourself playing hot potato with it if you hand it over to an unsuspecting friend haha.
This little hand warmer is an awesome investment and worth every penny! Hopefully the battery life isn’t affected too much by the heat that it produces, but time will tell.
