Mini Pocket Hand Warmers Rechargeable: 2 Pack Hot Reusable Handwarmers with 20 Hours Heat - 2 in 1 Portable USB Electric Hands Warmer - Winter Warm Gifts for Men Women Camping Hunting Outdoor - Blue

These heat up quickly and are great for my freezing cold hands in the winter. They charge quickly and stay charged for several hours. They are small enough to slip into gloves if desired.

Got these for my husband as he works in the cold weather during the winter. They do exactly as described and keep his hands warm. I would recommend these to others who are looking for rechargeable hand warmers.

These work so good. I like how they're small enough to fit in my hand and in my pockets. So warm, too! Easy to use, they look cute and the battery life works for a long time.

All I want for Christmas is to be invited to Amazon Vine. :) I am happy with these. My only gripe if the heat turns off after a certain period of time, and then comes back on. It's like it's timed to go in cycles. Possibly to keep it from overheating in your pocket. Not a big deal. My hands are still warm. It does get pretty warm. It's almost hot to the touch. That should be nice when it gets really cold. So far it works good in about 50 degree weather to keep my hands warm. I won't be able to test frigid temperatures for at least a few weeks. If I were to hazard a guess, I would say it would do a decent job of keeping your pocket warm in frigid temps if you have at least some insulation in your jacket.

Perfect for the winter the heat last a long time
