Hand Warmers Rechargeable-14000mAh,2 Pack 2-in1 LED Display Electric Hand Warmer,20Hrs Warmth Up to 131℉, USB-C Battery Heater for Raynauds, Golf, Camping, Hunting for Men Women Kids

These are small enough to not be too heavy but strong enough to hold a good charge. In the summer I can stash them in two different places to use his chargers, in the winter, they will never leave my coat pockets.

My sons ordered a two pack of black hand warmers for me for Christmas. Instead of receiving a box containing two black hand warmers I received one black and one orange in separate shipments. The orange units looked new. The black one was obviously a return, missing the security seal and damaged internal packaging.Pros, give off adequate heat. Size and feel are very nice.Cons, on the higher setting I got a little over two hours of battery life. No where near the 4 hours that they advertise. Also, the button to switch between the two power settings is very easy to press when warming your hands. I kept switching it to the lower setting which I noticed when the unit wasn't giving off as much heat.Overall I cannot give this product or company a positive rating.

Broken with only a few uses. Wouldn’t warm but just flash blue lights. Even after charging multiple times it still wouldn’t work

I've never had rechargeable warmers before, but these are exactly what I wanted and needed for a Minnesota winter! I'm thrilled to report that the "lowest" temp setting is perfect inside my mittens, so I'll get the longest life out of them on a single charge. The hotter and hottest settings are definitely hotter, if needed, but I doubt I'll need them. That said, they last for hours (I've been tubing for several hours with them in my mittens and they only went down a single "dot" from the place where they started. Super happy with my first rechargeable purchase and hope they last a very long time!

These worked out great and are very easy to use! These will come in handy for hunting and fishing.
