Jumkeet Hand Warmer Rechargeable, Power Bank 10000mAh, Electronic USB Pocket Heater, Portable Reusable Heat Therapy Warmer, Best Winter Gifts for Women Men, Outdoor Sports Home Office Usage

This hand warmer is brilliant.My wife often complains of cold hands. We have tried the liquid hand warmers of various types where you pop a disk in the gel and they get warm for a time. Of course, worth those you cannot control the temperature and they only last a couple of hours. We have always had trouble trying to boil them in a pan of water to reset them too. Overall, we found them to be rubbish.This electronic warmer is such a contrast. Turn it on and it is warm within a few seconds. You can control the temperature you want rather than being at the mercy of a chemical reaction. The device can cover quite a range of temperatures but for warming your hands without burning them we find 45 degrees is more than enough. At that setting the device can stay warm for over 8 hours easily. You are not left to guess what setting you are on as the display states the set temperature clearly. You can adjust the temperature in one degree increments up to something like 65 degrees. I can’t quite imagine when you would want that as it is starting to get uncomfortable to hold. You won’t change the temperature or turn it on / off by accident either. The buttons are on the corners and flush mounted. You must deliberately press the button so it is slightly recessed to operate it. Easy to do deliberately but not likely to happen by pressing against other things.The shape and size of the device is good. It fits comfortably in the palm of your hand or is easily clasped between two hands. It has a decent flat area so it won’t roll away when put on a surface. It is not a bulky or awkward shape to get in the way when kept in your pocket. Other electronic had warmers I have seen have weird shapes that would not be anywhere near as practical as this one.Once flat it is really easy to reset, or in this case recharge, the device. When charging the display counts up the percentage charge. It only takes a couple of hours to reach full charge again so easily charge over night to be ready to go again the next day. Uses a USB C connector to charge this device.We haven’t needed to try it yet, but this can also function as a power bank and charge any other device like phones, tablets, earphones etc. It has a standard USB port on it for outgoing charge. So all you need is a lead for the other device.Very happy with this purchase. Our friends tried it and were going to promptly buy one for themselves.

Most hand warmers are 5000mAh but this one is 10,000 so lasts a lot longer between charges. It's bigger than most hand warmers, double-sided and you can set the temperature from 45 degrees to 60 in 1degree increments. Display very clear and easy to read and there is an option to see how much battery life is left (percentage). Also shows the percentage when you charge so it's clear to see when you can take it off charge. Would definitely recommend.

The display is always on and unnecessarily bright. I can't use this thing because it might catch my eyes and blind me. It's just so unnecessarily bright, which is an unnecessary draw on the system's power. You can't turn the display off without turning the entire device off, which makes it useless as a hand warmer.It's fine if you want a torch/lamp that warms your hands while using it, or if you want to temporarily blind someone as a prank. It's absolutely ridiculous that a display this bright stays on all the time. It's brighter than my phone.For someone with photophobia, that really sucks.

Got these for my mum because we just do not handle the cold well, she's been absolutely LOVING this for her commute to work, waiting out for a bus in the cold wind has been a lot easier with warm hands. It was a little difficult trying to figure out how it worked, with regards to temperature and controlling it, plus she entirely overlooks the power bank aspect of this, but I can see that being extremely useful to some.

Works very well.It does not charge my phone very quickly and does not work with all cables and not at all through the usb-c port.The supplied cable is fine. It is charge only so is handy for public usb ports if you believe that they might be set up to hack your device.

Bought for a Xmas present she likes it gets really warm

This product has been a great purchase, I have bought three now as family members have requested them.

I like the overall finish of the product, its versatility as a power bank to enable emergency phone charge and ease of recharge. I will look forward to using it on cold evenings doing practical astronomy outside. It seems to be great value for money
