OCOOPA Magnetic Hand Warmers Rechargeable 2Pack, IP45 Water Resistant, UL Certified, Ergonomic Electric Hand Warmer, Up to 9hrs, Pocket Size, Raynauds, Golf, Outdoor, Tech Gifts for Men, UT4 Urban

Went on a ski trip and decided to try these out. They charge rather quickly and get quite warm. I Kept them in my pockets and never had cold hands. The fact that they magnetically connect to each other make them easy to store and keep together without losing them. The shape and size is comfortable in the hands as well.

Purchased these for my parents who's hands tend to get cold. Once placing in their hands on the lowest setting all I heard was Wow from Dad and Ahh nice from Mom.I purchased and had them use another brand hand warmer. They too worked very well and heated up very quickly. However these seem better for the folks. They fit better in the palm of your hand, less slippery but I might put a couple rubber bands around the warmer for something that helps them to grip, LED color indicator lights are easy to see/read, button to control is easier to use than the other one since it is right under the LED lights and button is oval and a smooth rubber material rather than hard shell of warmer. Charger uses common USB and has a rubber cap covering it and keeps it's charge for hours, 6+.I would definetly recommend purchasing these handwarmers.Note to anyone who enjoys designing and engineering. Design and have manufactured ones that have more senior usability. A lay down magnetic charger, hard for senors to plug any USB cords in anything, larger control button with a definite texture and larger led lights, eyesight also gets more challenging for seniors so they do rely on touch to help. Maybe rubber sides that help with seniors being able to hold onto it better.

Very nice and quick heating. The magnets on the underside of the both heaters works well and makes storage easy. I travel to Japan which has been cold and I used them frequently during my last trip. Long lasting warmth.

Don't fit in mittens!Work very well in pockets if you're wearing thinner gloves and warming up your hands in your pockets. Too hot on anything except the lowest setting when holding in hands on laying under wrists while typing at the computer (for Reynaud's symptoms while typing), but comfortably hot on the lowest setting against bare skin.They nicely warm the palms, but only the palm side warms up. Your palm will be toasty, but your fingers won't be heated while gripping it. Still comfortable to hold for small hands (standard glove size 6, nitrile glove size xs)

Works insanely well. Gets hot fast, I thought it wasn’t charging but it was fully charged. They are a bit bulky but still portable.

Who knew I would need these? When walking the dog on cold winter days my hands stay toasty. Sometimes I put them in my pants pocket to keep my legs warm. It's nice they came as a pair. They stay charged for a long time. I think the longest I used these handwarmers at one time is four hours. However, I don't charge them every day and every time I have needed them they are ready to go. They are very useful. I bought them because they are rechargeable. There are three heat settings. Warm, hot, very hot. They also come in a nice faux suede bag to store them when not using them. I think they are awesome.

These rechargeable hand warmers are amazing! They are so nice when it is cold outside.

These power handwarmers are wonderful for hunting, fishing, softball dugout and winter ski trips! Purchased them for the entire family for stocking stuffers and now they are often found in the car glovebox!
