OCOOPAQuick Charge Hand Warmers, Power Delivery 10000 mAh USB C Electric Hand Warmer Rechargeable Power Bank, 15hrs Long Lasting, 3 Heat Levels, Perfect for Outdoors, Great Gift Women Men

I currently have a petrol hand warmer, it’s a faf to fill and light. So the electronic hand warmers are appealing but I was concerned about performance.A friend showed me his and I was impressed enough to buy one. It was delivered a day early, very well packaged with clear instructions, so got it on charge immediately, really simple, just plug it into your phone charger. First impression, bloody hell the hot setting is very hot, you wouldn’t want to hold it in your bare hand for long, the medium or low setting is ample. They are weighty little things too, screaming quality manufacturing, again very impressed at the quality. Battery life seems really good too, turn it on with a press of the button and a minute or so and it’s up to temperature. Not tried it yet as a battery bank to charge my iPhone but in am very confident that it can and with ease. There is a link to register for warranty, did mine, very professional site, filled me with more confidence in this product. Would I recommend it to anyone, absolutely.

I bought one of these on a whim in the sales for just over £20. I thought, even if its rubbish as a hand warmer, it'll do for a spare portable charger as it delivered QC3.0. Anyway, it arrived today and I was impressed. It had a bit of power already in it. It's smaller than i expected- it looks pretty big in the pics. So it does actually fit in your hand. However, due to it being so small, it does leave me slightly sceptical about it having a 10,000 mah battery inside. However it heated up quickly. Level 1 would be ok for general usage, or level 2 if its pretty chilly, and maybe level 3 if its really cold. It's much more effective than those disposable ones than you snap and shake. However, unlike those, you'd struggle to pop one of these inside a glove. However they are fine to pop in your coat pocket, for a quick warm up. So after a quick play i let it charge using my Huawei 40w charger which worked and triggered the PD charge(middle light green). Within 3 hours it was full. So I've not had chance to see how long it lasts yet, or to check how it performs as a charger. To be honest, I probably wont even use it until the weather gets really cold, and even then, I'm sure i'll be lending it to others who complain more about cold conditions(kids/women). But I can't fault it so far. I actually decided to buy a second one too as i realised most people have 2 hands attached, and its too much hard work to move 1 warmer between pockets. But I bought from a different seller who had them for just under £20. Well worth the petty cash

Great for warming hands at football matches & walks too.

I suffer from Reynaud'sHaving left my original Ocoopa warmer in an airport, I purchased this newer version.Not as big as the previous version, which makes it easier/nicer to hold with one hand, and stow away in a pocket.The bigger battery means it runs for longer, and can be charged with micro usb or usb-c, like the original.The only gripes I have with this model is it doesn't feel as well made as the original, it creaks if I squeeze it, and I'm sure the trimbetween the 2 sides will come out at some point ? And like others have stated, the temp consistency isn't great.Dropped a star for the qc, otherwise a recommended product

The media could not be loaded. I've always used the microwaveable style "gel" handwarmers for myself and when my children were waiting for the school bus in colder weather. The problem with these is that once they are activated and gone cold, you can only reactivate them by microwaving or boiling them in hot water.This rechargeable hand warmer charges quickly but can be turned off and on again all the time it has power.In use, there are 3 heat settings which are displayed by 1, 2 or 3 *red* led lights and you can check the power left by pressing the on/off button a couple of times and it will light up to 3 *blue* lights. It heats very quickly, and I found the hottest setting really was quite warm so in use would imagine 1 or 2 would be adequate. Obviously, the hotter you use it, the faster it will drain power, bit you should still get a few hours use on a full charge. Just don't forget to turn it off when not in use!While charging, the blue lights flash and the hand warmer displays a green light and once fully charged, it turns to a steady green. It comes with a usb "c" cable but has an option to use a micro USB cable (not supplied) and also doubles up as an emergency usb charger if required. I plugged my mobile into it and there was no connection/charger problems.Also in the box is a silicone lanyard which stretches to fit over your wrist along with a plush storage bag.This handwarmer comes plastic sealed and would make a fabulous winter gift - I maybe making this top of my Christmas present buying list for relatives young and old!

Good product. Keeps the hands warm on those cold winter days.

The warmth it produces is great, but the time the hand warmer lasts for is not as long as the advertised time. Then again, I might just have a colder room than 25 degrees Celsius (since that's what the times are based on).

I did not expect to love this little thing! I use it more as a portable charger since it fast charges my phone but when I need to warm my hands during the really cold winter days, it serves well as a hand warmer. I'm so fond of this product that I ended up buying my dad one as well since he likes to hike and he's also been using it pretty consistently. I will be buying more of these to gift to people in the future for sure. I highly recommend this product.
