2 Pack Hand Warmers Rechargeable with Charging Case, Electric Portable Hot Hands Hand Warmers, Pocket-Sized Double Sides Heater, Winter/Outdoor/Indoor for Men Women

I live in the Chicago area and we can get pretty cold and windy. I dress for the weather but my fingers are always freezing even with heavy duty winter gloves. I walk my dogs everyday and was looking for something to help with the bitter cold days.Went to Holiday Magic at the Brookfield Zoo and tried these out. It was a warmer day, just above freezing, and I had my super warm gloves on but I kept taking them off to take pictures. I’d put the gloves back on, then put my hands into my pockets. I set these hand warmers at the hottest temperature. What I noticed was that if I placed the tips of my fingers around the warmers, they warmed through my gloves and kept the tips of my fingers warm, which helped to keep the rest of my hand warm.Today I went for a hike. It was 18 degrees. Doubled my gloves (with a liner then then a heavier glove.) Turned the hand warmers to high, and rested the tips of my fingers on the warmers. They worked great and kept my hands warm even at such cold temps.There are three heat settings. The lowest can be held with bare hands. The high gets pretty hot and worked well to permeate the layers of thick gloves. I haven’t used the medium setting yet.These hand warmers come with a charging box that I like. It a good storage container so you don’t lose or misplace the hand warmers plus you can charge the box (rather than the individual hand warmers) and while the warmers are in the box, they charge. The area I was hiking was about an hour drive away so I was able to keep the hand warmers in the box, keeping them charged, until I got to the hiking area. I had them turned on “high” for about 3 hours and they stayed hot.So far I’m very happy with them. I’ve had them for 2 months and hoping they last through the winter season.
