Lerat 2 Pack Hand Warmers Rechargeable, Portable Electric Hand Warmers Reusable, USB 2 in 1 Handwarmers, Outdoor/Indoor/Warm Gifts for Men Women Kids

Product manual indicates hand warmer should provid 11 hrs warmth at lowest setting. On repeated tests the maximum time I could get was 4 hrs 40 min on a full charge. Tests were carried out at room temperature from full charge until the batteries were dead. In actual use at about 1 degree C in insulated gloves power ran out at about 3 1/2 hours.

Best hand warmers ever!!!!!! Had them in my cart and was thinking about buying, then one day my niece said she bought a pair and she loved them so of course j had to get my own..... definitely best hand warmers ever!!! No need to use the higher settings because the lower one will be hot enough. Will be buying more for stocking stuffers this year

I have used the disposable hand and feet warmers for years. Thought I would give these a try. They were super easy to charge and they kept their charge for hours. The heat was consistent and a good temperature .

Hand warmers seem to work ok for now. The charger cord has a doubleoutlet so that you can charge both hand warmers at the same time. You need the charger plug like what you charge your phone with.

I purchased these last year and first used them on Halloween for my kids. (Michigan) I was very surprised with how fast they heat up & how hot they are able to get. They lasted us all night and we've used them countless t times since then. I liked them so well that I purchased another set just before Halloween this year :)
