Hand Warmers Rechargeable,12000mAh Electric Hand Warmers with Light, 2 Pack Pocket Hot Hands Reusable Up to 20 Hours, Double Sided Heat Portable Heater for Hunting, Camping Gear, Stocking Stuffers

I’m blown away by how well designed and their performance. Rechargeable. Feel heat in less than 5 seconds. Three heat settings are 113, 122, and 131 degrees. I stay at 113 because it’s pretty hot as hand warmers. All digital readouts tells heat settings, remaining power, and amount during charging. It has both usb-a and usb-c ports for charging. The more insulated they are while using heat the less power they consume. They can also be used as power banks to recharge a phone. I’ve used these heaters for a continuous 8 hrs several times and had 47-61% power remaining. General size is 4 x 1.5 x 1 inches. They fit very comfortably in your hands and pockets with nice rounded corners. Nothing protrudes out. Be careful about other items accidentally turning them on - like keys. Pretty simple to use. Long press to turn on/off. Double click to see battery power. Completely recharges in less than 3 hours. About 90 minutes using usb-c or car charger. On the backside is a bright adjustable LED flashlight that works the same way as the heater. With separate controls both heater and flashlight can operate at the same time without changing the other. The flashlight is bright enough to search the car, find keys dropped on the ground or to light up a door entry. And it has a strobe setting to catch someone’s attention. It comes very nicely boxed for gifting with two usb-c cables and a velvety drawstring pouch. I was lucky enough to buy them during Black Friday deals on a whim. So very glad I did now that its super cold outside.

Worked well but just didn’t last as long as I need them too. I did have them on the highest setting so it used more power

Wish that the charge would last longer. However these really help keep your hands warm. I think it would help seniors that have problems keeping their hands warm. As a home health aide I have let clients use them when they complain that they are cold. Great gift for people that spend time outdoors in the winter.

Worked great keeping my wife’s hands toasty in London for the New Years Day parade!

Well worth the money for these hand warmers. The battery life is great; we have used them at outdoor events in very cold weather and they keep your hands warm for hours. They fit right in a pocket and they are very comfortable to hold. They also have a flashlight on one side. Bought another set for my husband. These are a great fall or winter, Christmas gift, but if you camp and fish like we do when it's pretty cold at night, you will be glad you have them all year long!

Are there more than 5 star b/c I would give these little warmers a 10.I got 1 set and immediately ordered 3 more for myself so I am never searching for 1, 2 sets for my aged parents who walk everyday(gotta get their steps in), and my kids.What a lifesaver for enjoying the cold weather, getting to your cold car, movie theaters, or just a rainy day. Also, they last for days on 1 charge. Perfect size and fit. Has a handy 3 way flashlight built in too!Thanx!!!

So, the good thing about these is they do put out a decent amount of heat, albeit for a much shorter amount of time than is indicated. There is no way you are getting 20 hours out of 1 of these things, even on the lowest setting possible. I doubt you could even get close to 20 hours by using each one separately.At the lowest setting (113°), I am lucky to get 5 hours out of one. Within 2 hours of turning it on, it is already down to 40% battery. By the 3rd hour, it was down to 10% and it didn't even make it to hour #4. That is with the ambient air temp of over 50°F. With the battery down to 40% it takes an hour or more to recharge it back to 100% and when completely dead it takes substantially longer to recharge.The previous pair I owned (by another manufacturer but for the same price) lasted 3 times as long as these ones do. Unfortunately that set of warmers met their demise during hurricane Helene so I was forced to buy a new set.Also, the way this models buttons operate make it way too easy to accidentally change the temperature due to the buttons not being locked. Just by touching a button, it changes the temperature. The temp should not change that easily. You should have to hold the button down for a couple/few seconds for it to change so you do not mistakenly change it just by holding it.These will work in a pinch, but they are definitely not of the same quality of my previous ones purchased on amazon.

So glad I had these over the weekend!!! I bought these for work, getting up and driving the school bus in freezing temperatures can be rough. These worked great keeping my hands warm while I check out my bus and warm it up. Well, this weekend we went hunting, it's getting cold in the mountains so I brought them. An hour before dark we spotted elk and started stalking down this insane hill. We only had one flashlight and it quickly become dark out. I remembered bringing these so I used the flashlight feature. Over 2 miles we hiked in the dark back to the truck and these handy handwarmers saved the day! Both my kid and I used one each for over 2 hours of uphill hiking and when we got back to the truck they were still at 97%!!!! Absolutely amazing. I'm going to be buying more as gifts.
