Upgrade 20H Heating Time AI Hand Warmers Rechargeable 2 Pack, Rechargeable Hand Warmer,6000mAh Portable Pocket Heater, Golf Accessories, Camping Essentials, Gifts for Men, Women, Camping, Hunting

These little hand warmers changed my life! I have Reynaud's and my fingers suffer in the winter. The minute I get in the car, I turn on one of these and it warms my fingers right up. I use one at a time and keep one for a spare.

Great for the the out doors when your hands get cold. These are perfect for the outdoors person. Long lasting charge and it does as is it intended to do.

These are small, but powerful, the lowest setting is sufficient. I like that they stick together with the magnets, so I don’t lose them. They work well and hold a charge. I got one set for my dad for hunting and an another for me when I watch my nephew’s hockey games. The value is good for the money. I like the color options. They’re very durable too. I’ve dropped them a few times when they accidentally slipped out of my pocket.

These little hand warmers perform exactly as the description says: instant heat that's adjustable to your personal comfort.They're about the size of two Oreos laid side by side--maybe a little thicker. They fit well into the palm of your hand. After you turn them on, heat starts in a few seconds. It seems to cycle: very warm, then decreasing, then very warm. This is probably to conserve the rechargeable battery, but it's still effective.Only one side heats. If you want two-sided heat, you clip them together with the built-in- magnet. Most of the time, I've found the lowest setting adequate, although I have used the medium and high setting a few times when my hands were very cold. Instructions say a full charge takes about 3 hours. Because the charging cord has two separate leads, you can charge both units at once. That's handy.My only complaint is that the LED indicator lights are extremely tiny, smaller than the head of a pin. Outdoors you have to shade it with your hand to see it. But considering how well these work and for the low price, that's a very minor problem.If you suffer from cold hands, you'll really enjoy these. I expect to get a lot of use from mine.

These heat up within seconds. Each one uses a type C charger (so you need two chargers if you want to charge both at the same time) You cannot turn them on while charging.Long-press the power button to turn on and off.Short-press to cycle through the three heat settings (1, 2, 3, 1, 2, 3)Setting 1 is pretty warm, but 2 and 3 get very hot. Possibly hot enough to burn your skin, but if you're putting them in pockets, you need that extra, little oomph of heat.They are magnetic, so you can keep them snapped together when you're not using them.My main inconvenience is that they're designed so that only one side of each warmer actually heats up. (It isn't 360° heat), which doesn't feel like it should matter, but when you're holding them, the part of your had that is touching the side that doesn't warm up really feels that absence of heat. If I bought another pair, I would look for a different setup that would heat all around so that I don't have each hand 50% warm and 50% cold (I have to decide if I want warm fingers and a cold palm or vice versa). I know I can just flip it and give each part of my hand "turns" of comfort, but it's still dissatisfying and distracting.I'm still happy with them and they were a decent price point, it just shows me what I actually want to look for if and when I decide to get a different pair. To be honest, all my friends think it's the coolest thing and I have gained cool points because of them. It's a great li'l party trick. (Also, I've dropped them pretty hard a few times, and they don't show any signs of damage)

I bought these to put in my lunch bag to keep it warm. They work really well. I put them on the highest setting and put them in with my (wrapped) food inside an insulated bag, and they stay hot until I'm ready to eat. I can use them that way for two or three days without recharging (I work part-time, so it's only a couple of hours). They don't keep my food HOT, but warm enough that I don't have to eat a cold meal. My only "complaint" is that the little indicator lights are microscopic, and you have to hold them at a certain angle to be able to see them. Other than that, I've had no problems. I will update if anything changes. (written 2/13/25)

Used these for hunting, lasts a very long time on a charge, warm hands for the day!

Been using these since Christmas. Batteries last a long time and recharge pretty quick. I use them on the lowest setting and keep them on for 3 to 4 hours a day. Medium and high settings are almost too hot.
