Best cold weather hand warmers ever
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.

AMAZING 🥰🥰
I BOUGHT THESE TO REPLACE ANOTHER CHEAPER SET (THEY WERE NO GOOD) BUT I AM BLOWN AWAY BY THESE LOL 🙂 THEY WORK SO GOOD AND GET SO HOT THAT YOU HAVE TO TURN THEM DOWN TO LOW OR MEDIUM 🙂 I LOVE THEM AND NOW SENDING THE LINK TO EACH ONE OF MY KIDS AND GRANDKIDS SO THEY CAN GET A SET 🙂 THANK YOU SO MUCH 🙂

These are amazing and do what they are designed to do, and some
I bought this for my husband who works outside. We have tested them out inside so far, and they heay up great. There are 3 heat settings, with a very noticeable difference between the lowest and highest. There is a flashlight which I didn’t expect much from, but it has a great light with 3 settings as well. My husband has been using his phone flashlight at work an now this will more than work. It also is a portable battery charger that will be handy for him if his phone runs low, he can now charge it when needed. They come with a little lanyard to keep them secured to your wrists, that we can’t get on them. That would be our only complaint. This is not a big deal to him as it doesn’t affect the purpose/function, and my husband said he wouldn’t use them away. The display is nice. It does take a while to charge. Each one comes with a charging cables.

Battery time is highly overstated.
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.
