Hand Warmers Rechargeable, Hot Hands Hand Warmers 5200mAh Electric Portable Pocket Hand Warmer/Power Bank, Heat Therapy Great for Raynauds Arthritic Sufferers Pain Relief

My wife has been using a similar one of these since last year and absolutely loves it, so we got another for the grandmother, who saw it and thought it was brilliant. So basically this is a phone-charging power bank, but the bonus is that it doubles up as a small pocket heater. It has three different heat levels, and you basically press the button to activate the heat mode and then slip it in your pocket with your hands, it works great if you have one of those 'pouch' style pockets on the front of your jumper or jacket. You charge it with a standard USB cable just like any other power bank, and you can use it when you're out and about to charge your phone with a USB cable too, just like a normal power bank. When you use the heat mode it does reduce the amount of charge available for your phone but it's very efficient and well worth the trade off to us. The packing box comes with a neat little magnetic flap too, so it's quite nicely packed.

Fortunately, this winter has been so mild that I've only had to use this a few times. As a postman, your hands get pretty cold so I slipped this in my bundle carrying hand, in my glove, and it worked exceptionally well. Full power was a bit much after 10 minutes so the mid setting stayed on for the 5 hour route march till it ran out of juice. I'll keep it with me right through till there's no chance of frost. I'd recommend it to anyone who suffers from poor circulation or cold extremities.

The batteries don't last long so that was my dislike part from that it's pretty good very warm.

Written by my patner who I purchased it for:Really useful for both charging of devices and hand warming function (actually, I've used it on my lower back and chest at times too!), but difficult to control certain functions (which has cost it one precious star) as times as there is only one button which controls everything and it's like having to figure out morse code at times depending on what you are after!!!!! One thing I will say however is that when you set it to the highest heating (ie 3 red dots), the heat is sensationally HOT which really helps my Raynards condition tremendously :) It does have a relatively short battery life (ie 4-5 hours) so you do need to charge it daily if that's how you're using it, but on the whole, it's a very handy little device that I now wouldn't be without.

Bought this for a Remembrance day parade as I have arthritis and I can get cold and it's blummin cold.It is worth noting you do need to charge it first but it lasted me on full heat the full three hours.I had a simular one last year but this on has a few added benefits, namely that it has two different charger plugs you can charge via usb c or micro usb which for me is ideal. It also works as a battery pack from a standard usb

I bought this for my partner as they suffer from cold hands in the winter time. I was really impressed by it as it's easy to use and has three settings of heat. A bonus is that it's a power bank as well so you can charge your phone or any other device whilst using it is a hand warmer. Great device and worth the money paid.

Had this for a while now and it's holding up well. Previously I used chemical warmers but this is a better shout. Lasts surprisingly long, takes a while to charge back up. Recommended

Very warm on high heat setting and it lasted 3 hours. It is better quality than I expected for the price.
