8000mAh Hand Warmers Rechargeable 2 Pack, Electric Portable Pocket Heater, Dual-Sided Safe Heating, Reusable Hand Warmer for Outdoor, Hunting, Golf, Camping, Winter Gifts for Women Men

I must say these hand warmers are a must have for any parent that spends their life of the side lines watching their children play sports. Both my sons play football and during the winter periods and it is absolutely freezing on evenings and weekends on a football pitch somewhere. Well not anymore, these compact hand warmers pack a punch and I am now the envy of the other parents. They have three settings which is great as I can put them in my pockets on max temperature or inside my gloves at the lower temperature both keeping me warm and cosy so I can focus on watching my lads play footie. They click together if you want to hold them in one hand, great ergonomic design and the charge seems to last forever. You can also charge them in the car which was handy as I forgot to charge them last week so a quick charge gave me so much heat. I even now take them when I go for a dog walk which really helps my arthritis as they keep me so warm. Parents get these now they are definitely worth the money and more importantly keep you soooooooo warm !!!

These hand warmers are great during this time of year. I've used them two weekends in a row and I have to say they make a big difference. There's no boiling them in water and can be used multiple times. There's even an option to change the temperature of the units. The hand warmers are actually a set of two but they can be combined to form one larger unit. Each unit is independently controlled so I'm not sure what the benefit is of them being one unit, I used them separately - one for each hand. Packaging wise they are well boxed, they come with a case, straps to put round your wrist and a charging cable. I like the charging cable, it's a split usb one that allows you to charge both devices at once. It's only a little thought but actually makes so much sense. The devices themselves feel well made. The top setting can get very toasty after some time but you can lower this. I had this on the bottom setting and was standing out in the freezing cold waiting for my daughter to come out of some rehearsal for half an hour and this kept me warm.... yes, keeping your hands warm whilst wrapped up makes a difference. I think it's something to do with blood circulation. Going to buy a set for my dad for when he goes out.

Being of a certain age I do suffer from cold hands during a UK Autumn/Winter so I thought I would invest in these hand warmers and very "handy" they have proved to be! (Forgive the pun!) .. They certainly are very effective but as other reviewers have noticed, to warm both the hand and the fingers, you really need to use them as a magnetically attached pair. I still tend to only use one, just rotating the item between hand and fingers.. The charging time is long admittedly but they also do last quite awhile between charging periods.. Overall I would recommend them, just losing one star having to use as a pair for total effectiveness..

Amazing used when it was cold I use a mobility scooter so my hands are always cold but the temperature setting and being able to alter that and turn them off and charge them up excellent and a nice size and smooth to touch and a little bag to put them in when not in use

Bought these for my wife as she suffers from Raynauds Syndrome and struggles with her hands when watching our son play matches during the colder months in winter. They are really well made and smaller than they look with a digital display showing the temperature and small leds showing the battery level which only light up when selecting the desired temperature. They are very discreet and work really well and give off a surprising amount of warmth. Haven't tested them enough to see how long they actually stay warm for after a full charge but they were on full for 2 hours and were still going strong.

I have been using this item for a few days now, It is an excellent device compact, easy to use and heats up very quickly, though only used the lowest heat setting it is still quite warm and the battery lasted a few days, well recommended. The only quibble is that the carry pouch could be a little larger as it's a tight fit with two heaters and a charging cable.

These hand warmers have been a total game-changer for weekends spent freezing on the sidelines watching my kids play sports. They heat up quickly and stay warm for hours, keeping my hands toasty no matter how chilly it gets. The dual-sided design is genius, cos you feel the heat on both sides. As there's two it also means you can share one or keep both for yourself. Compact, easy to charge, and perfect for outdoor parents like me—these are a must-have for cold weather that's gonna get colder.

They work ok but only really get about 5 hours out of battery from full charge on lowest setting don't know where they get up to 20hours as stated unless mine are Faulty??

These hand warmers are great! The set comes with two hand warmers, one for each hand! It starts on high and you can turn it down twice so there are three settings. The settings are in Celsius which doesn’t matter as you know if it is on high, medium or low. The high is at the upper level of how much heat I would want which is perfect. It comes with a USB cord that has two connectors so you can charge both warmers at the same time using one USB port. The backs are magnetic so they can stick together as one piece. They have loops to put around your wrists so you don’t drop them and a carrying/storage case as well. One side heat up and the other does not so they are quite safe. They are very sturdy and seem well made and I expect them to last a very long time. The warmers can also be put in your pockets to warm your legs. I live in Minnesota and these are going to be used all the time.

Great product, does what it’s supposed to. Quick heating time and very hot delivery (maybe a bit too much), but it does the job. For the price and the length of battery, I’d say it lasts quite long. Usage factor is dependent on the person, but I could use this all day with no issue.

Lasts four a very long time and keeps my hands warm, which is the whole reason for them. They heart up really fast and get very hot.

These hand warmers are compact, easy to use, and come with a convenient carry case, which is great for safety, especially when using the hotter settings. They charge quickly with a USB-C cable, and include lanyards for easy access. While they claim to heat both sides, they are actually two one-sided warmers that can magnetically join together. The instructions are clear and provide good safety information. Overall, I'm happy with the performance of this product and would recommend them for anyone needing quick and convenient warmth during the winter season.

These hand warmers work, maybe a little too well. The temperature settings are in Celsius, not Fahrenheit, but even the lowest setting is pretty hot. They definitely work like they are supposed to, but the battery life is not all that long.
