Hand Warmers Rechargeable - 2 Pack Electric Hand Warmers 14000mAh, 16 Hrs Warmth Dual-Sided Heating Max 131℉, 4 Heating Levels Battery Operated Pocket Heater for Raynauds, Hunting, Golf, Camping

These have been extremely useful working in winter in a not heated manufacturing environment.Pros:Heats up quick. Once activated, it's warm after about 5 seconds.Consistent heat level. Once set to a heat level it maintains that temperature with no noticeable fluctuations.Great battery life. Lasts a 12 hour shift, even using both with both sides heated to 2.Intuitive button control. Once you get used to which side does what and how long to press, it's very intuitive to turn them on, change mode and heat levels while keeping your hands in your pocket.Also usable as a power bank. Really handy to have around in power outages.Cons:None, honestly.I could however do without the built in light. It's not very bright, more of a soft glowing LED type light. I'm sure it could be helpful but I have no use for it.

I am very happy with this item I bought it a year ago while I was doing alot of work outdoors running them on the lowest setting generates pletty of warmth if you are reading this review know that you are buying a good product if you work longer then 8 hours I would by two sets note the temperatures i was using these in was in the 30s to 40s F on the lowest setting to preserve battery life to make it last the whole day

I work outside, and staying busy my hands are ok. But on my daily hikes with my 3 dingos, my hands get cold in the winter. Sick of stuffing them in my jeans, so thought Id try these. Holy crap...the best things I ever bought. Ive been using them for months now every day on our trail hikes!!!! My hands are toasty and I love these things. I returned another brand that only did one side, and bought these, and the double sided is SOO much better. Bought a second pair for my oldest daughter. Great product holding up very well, and I get about 3 to 4 days 2 miles hikes out of them no issues.

A four because they work great but are quirky when recharging them.You can start off at 8 or 10% battery when you plug them in. After a half hour, they might reach 16%. Later, the screen will be dark and you jiggle them and light back up as charging at maybe 18%. Sometimes, I unplug and turn them on then off and plug them back in and they start recharging.Somehow, after a few hours, they hit 100%.Once powered on, they do provide great warmth. The battery indicator seems quite accurate as you're using them.Depending on outside temp, I've been getting about 2 hours on H2 and still have about 50% battery.I was going to return them because of the charging quirks, but they do recharge and last a long time once charged.Others have mentioned random button clicks. I've experienced this but realized it was due to me squeezing them.

I’m so glad I ordered these rechargeable hand warmers! They heat up quickly and stay warm for hours. The compact size makes them easy to slip into my pockets or gloves, and I love that they’re reusable and eco-friendly. The dual-sided heat is a game-changer, and the temperature settings let me customize the warmth to exactly what I need. Plus, the battery life is impressive!Highly recommend for anyone who wants to stay cozy without constantly buying disposable warmers. Great purchase!

Bought these for my mom for Christmas she lives them and says they work great. Charge easy and fast

These are bulkier than some others, but that's because they provide heat on both sides. That's a nice feature. If you have small hands, you may find them uncomfortable to hold.I wish someone made handwarmers with inductive charging, so there wasn't an exposed USB port. Maybe someday...

I bought these because I have an issue with cold hands. I like that they heat on both sides at once. Or if you prefer just one side. The on off button is on the left side it also controls if you only want one side to heat. There is another button on the right side that controls if you want both sides to heat at one. It goes from L1 up to L4 if your heating both sides the L indicates both sides are heating. If you only want one side to heat it also has 1 ( lowest setting) to 4 ( highest setting). If you keep this in a coat pocket for me I use the lowest setting and it keeps my hands warm. If it's a bit windy I might use the next setting up but anything more than that and it's too hot. On the lowest setting for both sides heating it heats for 6.5 hours. I haven't used the one sided so I don't know how long that would run. I found that if you use this with a Hoodia that has the pouch pocket in the front I have to use the second to the lowest setting. I love the fact that this is one unit and not having to put 2 units together ( I have a set of those as well) to get heat on both sides. This keeps my hands warm and fit nicely in my hand when I hold it. They aren't too heavy which I like. So far they are holding up nicely. Im thinking of ordering another just so I can have a set fully charged and use while the other set is charging.
