Hand Warmers Rechargeable, 1-Pack Hand Warmer Reusable 5200mAh Electric Portable Pocket Warmer/Power Bank, Battery Operated Hand Heater Great for Outdoors, Camping, Golf, Warm Gift for Men Women

I use it for my hands because I have a condition (raynauds) that doesn't let blood flow well to my fingers. This is a very handy product.

Gave two of these to my son and wife who live in Minnesota. They have dogs who are walked regularly outside. This is a great way to keep their hands warm on a very cold day.

This was a gift.

I have always kept Chemically activated hand and body warmers because my wife feels cold quickly when the temps go down doing activity outside. I never purchased a rechargeable heater because I have a bit of prejudice about them that they do not heat up fast enough and they don't last long. but this battery heater has changed my view. I will be getting these types of heaters from now on. This particular heater heated up to 110 F degrees within 40 seconds. It literally starts to heat up a second or so after you hit the button. I had it sitting on my desk for about 4 and a 1/2 hours and it started to cool down but kept the temp all along. I only had it set at the lowest level thinking that it could melt my desk if I set it on highest setting. The lowest setting was hot enough for me. It may have lasted longer if I had it in my pocket I think. I live in So Cal and it is still hot here so I did not want to overheat . I am now sold on battery powered hand warmers. This heater works great!

The charger arrives in this black box, and was well secured. If your using this as a gift, its very unlikely it will be damaged in shipping.It comes with a small charge, so i let it charge up to 100% before any testing or activating the heating element. To charge is an included cable that is USB-A to USB-C with the battery bank using only USB-C. There is an included adapter to convert the USB-A to USB-C so you can charge via either or. This is a nice touch and i think a fair middle ground (most devices should be pushing to typeC so this is a nice compromise between older and newer devices that might need a charge.After charging the unit up i was able to turn on the heat, and it gets very hot (in a good way) Wont burn your hands but i can easily see this being thrown in a jacket pocket etc. and keeping hands nice and warm.The charging ability is nice. It wont fast charge your device, but will provide the full 5W and about 1000aH charge as detected on my phones app. It does fluctuate, but ive seen this many times in favor of protecting the battery.With a modern smart phone, you can get a single charge.I see no Con's in this device. it heats like advertised, and it charges with decent speed, and protection against the battery.

I live in the midwest and It is currently freezing. I do like to go outside and go for walks but it can get a bit frigid in the morning. These hand warmers are a life saver! This is such a genius idea and I am so glad I own a pair! I will definitely be gifting these during the holiday season. I have a few ski trips coming up and I cannot wait to pack this hand warmer!

Easy to use and warm! Great to have in the car on cold days.

This hand warmer works great and actually gets a bit hot and I haven't fully tried it but it likely gets that hot to use over thinner gloves so you don't have to take your gloves off to use it and you can warm both hands at the same time. I have had no issues yet with it and it's worked really well on the cold days we've had
