Voneta Hand Warmers Rechargeable, Reusable USB Hand Warmer 10000mAh Electric Portable Pocket Hand Warmers, Double-sided Heat Hand Heater with LED Temperature Display Screen for Winter

Bought this for keeping my bowling hand warm during the winter months and on cold evenings. Have always used the one time chemical pads before so was a bit dubious whether this would produce as much heat and for long enough. It certainly did and on just the lowest setting. Heated up very quickly too. Seems sturdy and well made so should last for years saving me quite a bit of cash. Only downside I suppose is that it's bulkier in my pocket but not really a problem.

I bought 2 of these to use to warm my hands whilst at work. I fully charged them both yesterday (overnight charge) and gave them a try today. I set them to the lowest heat setting and used them in the plush bags which comes with each one. They kept a good constant temperature throughout my 8 hours at work, and finally ran out of power after about 9 hours (much more than I was expecting)I really like the design of these, and although at first they looked a bit bulky, they are actually a really comfortable size to hold (I have hands which are on the smaller side). They heat up quickly, and the option of three heat settings is really nice too. I found the lowest setting adequate all day today, the middle setting I would say is warmer but still pleasant, and the hottest setting seems quite fierce (perhaps good for when wearing gloves as well).The operating button is quite easy to press accidentally which will change the heat setting, and it would be nice if the supplied bags came with one of those little plastic chord stops as the draw string closures on mine tend to open by themselves (got this covered now though and will be adding some chord grips myself).I did check that mine are the 10000mAh version, and they are.Early days, but I have been really impressed with these today, especially at this price.

Be aware that I was sent 6000 mah instead of 10000 mah Voneta handwarmer not what I paid for.

Works quite well with a few issues. There are three temperature settings, 40C, 50C and 60C, 40C being comfortable 50C/60C being too hot unless the warmer is kept in a pocket or in it's sleeve. There is no way to lock the temperature button so, while it is recessed, it is still quite easy to accidentally press. and increase the temperature to maximum (the next setting after 40C). Also if the warmer is left on when not being used then the heating surface gets very hot!!Can also be used as a battery backed-up USB charger.

Fantastic, virtually instant heat. Choose 40,50 or 60C heat. 40’s fine for me. 60C is scorching! Like holding a tablet of soap. I work outside and it has been a boon in these freezing days of Jan 2021. I bought two and have them on in each pocket to warm my hands very quickly. Highly recommend

The design of the hand warmer appeals to me. Seems well made. It is chunky but fits into the whole hand rather than just the palm. Its size also means that both hands can warm up by clasping it between the hands. It gets comfortably warm at the 60C setting but not great below that. No idea how long it stays warm as have not been able to play a round of golf since I got it due to the lockdown. Hence the four stars. Hopefully it will work out well.

I bring it everywhere on my lockdown walks. I used it to charge my phone and about 1/4 of the charge was used up fully charging my S9. You can regulate the temperature of the warmer. And it charges up fairly quickly. It did make a bit of a hissing noise when it was fully charged though so I wouldn't leave it charging overnight or for hours unattended just in case. I will update the review if I notice anything else. Very happy so far as it saves so much space in my pockets/bag and it's great value.

This product claims a 10,000mAh battery, but when the product arrived it was in a box that had two options 6,000 and 10,000, neither of which was marked. So we don't know if we got the advertised 10,000 mAh version or 6,000 one.Problem was we have another from a different supplier with a stated 7,800 mAh battery which lasts the entire day between charges.This product lasts a few hours.So, it was returned.
