Review: Versatile and always ready - I have tried or considered various hand-warming solutions as I find even with gloves my hands get cold. I wanted something to help keep warm when standing watching my son play sports or for going on walks. I have tried the disposable hand-warmers (seems wasteful) and the rechargeable natural ones (get hot but not for long) before considering the fuel or electric variants. I discounted the fuel ones thinking once they are hot they stay hot and there's a chance I could forget or run out of the fuel. The electric rechargeable one seemed the best option. I had been watching deals on these before finally ordering one after a particularly cold day. I was pleasantly surprised with the quality of it - it doesn't feel cheap or flimsy. It's super easy to use and reassuringly warm without getting too hot which was one of my fears. It's therefore fine to use without a case and for my children to benefit from too. The ability to top up the charge on my phone if needed is an added bonus as we do sometimes take a power bank on walks. I also like the idea that, when we go on longer trips, we can top the charger up in the car so as long as we have it with us we will have warmth. I'm actually thinking of buying another now, one for each pocket and for sharing with my family when on walks together :-)
Review: Hand warmer - I love this hand warmer/power bank. For years I've put up with cold hands from poor circulation and working in the cold elements of the Scottish hills. I've tried every way possible to warm hands and fingers to no avail. Cold hands are no more of a nuisance and sourse of pain thanks to this solid, quality feeling purchase. The hand warmer is just the right size when held in hand and produces a lovely heat in 3 settings. When I'm outside I use setting 60 and in home setting 50 and as I enjoy warmth I put hand warmer on setting 40 and leave it turned on in pocket for a lovely warm feeling. Battery life is great and I'm sure as stated in the description because I had hand warmer on on medium heat for over 8 hours. Charge time is approx 3 to 5 hours from depletion to full charge. I've used power bank facility briefly and it worked as stated but I purchased the item to warm my hands and it does it magnificently. I'm so impressed I'm going to buy another for my my mum who's a lollipop lady out in snow, rain and wind I know she'll be happy.

### ⭐⭐⭐⭐ Not 10000mah but still warms your hands...
*by L***E on 30 November 2023*

Only done a partial test on this, when there's lots of lights on the battery it gets super hot, but as the smaller than advertised battery drains the heat seems to scale. I took it from 2 lights all the way up 4 and it took about 2200mah, initially drawing 1.6 amps but that quickly dropped. Dont buy this to recharge your phone, buy it cos its a cheap rechargeable hand warmer. Will test again when I've run the battery down again.
