Letouch Rechargeable Hand Warmers 5200mAh Power Bank, Electric Hand Warmer Double-sided Heating Portable USB Mobile External Battery Charger Best Gift in Winter for Women, Man

I have Raynaud’s disease in both hands and suffer terribly with it, specially when dog walking and chicken keeping etc, my poor hands just go white, I bought just one to try, an boy is it good, I’m amazed by the little power block, so much so I’ve recommended on my Facebook Raynauds page for people to buy one, The heat is amazing on any setting, lasts for ages on a charge, throughly recommend

Threat little gadget. I’ve only used this once but it warmed up I thin seconds and heated my coat pockets fast. It was on the lowest setting too.It comes in a nicely packaged box containing a cloth bag, small wrist strap and short charging cable. There’s no charging plug, you’ll have you plug it into a PC or a USB power supply.The device fits into my palm nicely but I have quite large hands so it may not be for everyone. The sides are nice and smooth and comfortable to hold.A long press of the only button, sets the gadget into hand warming mode and short presses set the power level. Judging from level 1, the other ones will be too hot to hold comfortably and would need the bag.Recommended.

I took one of the into the welsh mountains to do some photography, and I am glad I had it- despite having chemical hand warmers, the sub zero temperatures and North Easterly Words made it feel bitter. Taking pictures with gloves off resulted in very cold hands, which the chemical hand warmers alone were not fixing - popping this into my gloves for 5 minutes made a huge difference, and got my hands to temperature again - its also useful as a charging device. I don't know how long it would last if on permanently, but it was used a lot, and still performed each day on its charge.Worth every penny to have warm hands again!

If it is really cold, I got blue fingers.... but not any more. The hand warmer comes with a draw string bag, which is useful on higher settings to avoid it being a bit too toasty to touch. In my case it is handy to pop in my pocket whilst walking our deranged Springer Spaniel, she requires lots of walks, regardless of icy blasts or tempests. So far I have only needed to use the low setting and popped it in my pocket. Certainly, putting it in your pocket is the way to go, as it provides a little haven of warm air. just holding it in the open would probably not bring much benefit. I don't actually know how long it keeps going, but certainly several hours. It is also excellent for recharging my phone or e-cigarette in an emergency.

Product arrived.Looked great . Switched on and was partly charged charged . Heat perfect . charged it up fully .. took about 3-4 hours . Switched on to check and on/off button and it slid to one side under the plastic . Could not retrieve so would have to use something to depress button . Ok sometimes things happen so thought will return for a replacement . Raised return request which is done at my expense and have to claim back . The biggie is that cannot return by normal post but a courier due to lithium batteries. So now have to find a courier . Difficult as in rural area. So may well have wasted my money!

Exactly as described; purchased three in rose, blue and silver, considering purchasing another. Heats up very quickly, easy to charge with a smart charger, last several hours. Mother loves it and using it for her aches and pains as well. I've used those gel ones, thin plastic water bottles and microwavable wheat packets and they are all useless, these are much better, purchasing neck strap to hang inside my clothes.

I bought this to use in a particularly cold classroom. I was immediately very popular, and a bunch of my classmates bought one after they borrowed mine. It heats up surprisingly quickly and is really pleasant to use. It's easy to use with the light indicators and I love that it doubles as a phone charger.

This is a good handwarmer in operation, it's a good temperature and it's more convenient than handwamers that run on fuel. However the battery life gets eaten quickly, I can run it down to 1 out of 3 bars in an hour on the lowest setting. I'm bouncing between 3 and 4 stars. I'm giving it an extra star just because it works well in the wind. I have so many issues lighting a lighter fluid powered hand warmer in a strong wind. However lighter fluid lasts a loooong time. I also have concerns about battery cycle life as you are heating a battery and then discharging it, and batteries aren't fond of high temperatures. Assuming it lasts a couple years (hopefully more) I think I'd get another one just for the convenience when out for a short time. Although I might look into charcoal warmers.Edit: After a short amount of time it desoldered it's charging port from the heat and became useless.
