Pocket Size Hand Warmers Rechargeable 2 Pack, AI Smart Chips 3 Levels Heating Ultrathin Electric Handwarmers with 4000mAh, Portable Electric Hand Warmer, Hunting Camping Hiking Men Womens Gifts

Why did you pick this product vs others?:I gave this as a Christmas present to my friend who suffers from cold hands but goes for exercise walks every morning including the Winter. He has raved about how well they keep his hands warm during the cold weather, how long they stay charged and appreciates their small, easy to handle size.

My husband works in construction and leaves the house early in the morning hours. We live in Utah so the weather gets pretty cold. He loves them and won’t be without next year

These work great! They stay warm for quite a while and they are comfortable in my hands. They don't take much space in my pockets.

This work great for my husband who works outdoors in the winter and also rides a motorcyle in the cold weather.

I LOVE how small and lightweight these are, especially as compared to my other much larger & heavier rechargeable hand warmer! These heat up quickly. I tend to use these for short bursts, so I can’t comment on duration of heat. The only problem (and it’s a big problem!) is that these heat only in the CENTER of the square, and mostly on the rounded or bulging size. The lack of heating to the edges makes it difficult for me to hold these gripped in my hands while simultaneously heating my fingers and fingertips, the area that needs it most.So these are only adequate for my needs at best.

Really love these hands warmers- so nice that I don't have to worry about them running out of warmth as they last a long time. There are 3 different heat settings which are noted with 1 red light, 2 red lights, or 3 red lights. The lights are a little close together so it can be tough to see if 1, 2, or 3 lights are illuminated. The brightness of your surroundings seems to have an impact on how easy it difficult it is to see those lights. On the hottest setting it got almost too hot- which is a good thing since they can just be turned down. I'm glad I purchased these.

This is the second pair of hand warms I purchased from this vendor. It's got some improvement over the first version in terms of speed to heat up. It really takes just a few seconds and the lowest temp setting is already quite warm. The inside magnet is stronger than the previous version as you can stick the pair firmly back to back so they heat up both side. The small size means you can easily fit them into your gloves. The price is great considering how much you'd otherwise spend on disposable warmers (Once open they heat for hours but you actually only use for a small fraction of time here and there!).

Not a fan of the single sided hand heaters but I knew what I was getting. Goes two hours on high heat so their estimate of 5 hours is bs. Actually, I’m not sure why I bought these, I like my 6,000 and 10,000 mah double sided warmers. Single sided ones really are kind of worthless for my use.
