AI Hand Warmers Rechargeable 2 Pack, Real-Time Temp & Battery Display, Electric Hand Warmers, Fast Heating, Fits in Gloves/Pocket, Gifts for Women & Men

My hands are always cold. So I have lots of different hand warming options, but love that this is the the lightest set I have. As it doesn't have magnets (never understood why you need magnets) it saves a lot of weight. I charge them during the night and put one in both jacket pockets and enjoy during the day. They are small, easy to turn on and off and pick the temp setting I like. Also when I have a shirt pocket I have learned I can drop it in my shirt pocket and keeps my chest warm. Well made and it seems to go from 100% to 90% fast, but it seems to takes me the rest of the day using them to get to 0% and them turn off. So I am happy with the battery life. Easy to store in my jacket pockets as they weigh almost nothing.

Great product that is easy to recharge. Use them for deer hunting, golf and sporting events. The different level settings are great based on your activity.

1. Description for these on Amazon (and above) says 6400mAh, but that's for BOTH combined. I was under the impression that they were 6400 mAh each.2. The warmers work just fine, with three heat settings. They heat up very quickly. The hottest setting is too hot for my hands, but my wife thinks the top setting is just right.3. They're somewhat small but put out serious heat. Only one side heats up, which is fine with me but might be a negative for others (my wife prefers her two-sided warmer).4. Controls and display lights are easy to use. I like that a USB-C port is used for charging instead of older design ports. A short (6 inches) dual output USB-A to USB-C cable is included so you can charge both warmers at the same time, a nice touch.5. Both warmers came with some charge (1 light out of three, so <30%) and took about 90 minutes on a 30 Watt charger to fully charge them, so not too bad. I haven't done a run-time to end of battery yet.6.. Overall a good product at a good price. I'd recommend it.

I chose this item as a gift for a Christmas gift exchange with friends and acquaintances. According to those who received it, the size was good, and the product lived up to the description in terms of longevity and warmth. They all said it was great. I’m considering buying it again in the future.

Overall, the combination of functionality, style, and heartfelt features makes them an unforgettable gift and a reliable companion in the cold. I recommend them for personal use or as a present for friends and family.

I recently purchased these hand warmers and was impressed with how quickly they heated up, just as the description promised. They were incredibly effective and kept my hands warm.However, I was disappointed to find that they appeared used upon opening the package. The outside packaging appeared sealed, but the warmers themselves had some visible scratches and what looked like visible wear. Very unexpected for a new product.Other than that, the product is great! Keeps your hands warm, heats up very fast and is small enough to fit in your pocket. If it wasn’t for the “wear” on the product, I would I have rated this a 5 star product.While they performed well, the appearance gave me second thoughts about the quality control. I’d recommend these for their effectiveness, but I hope the seller addresses this issue to ensure a better first impression for future customers.

Husband loved these- kept him warm. Doesn’t use them often so can’t speak on battery life. Good temperature though! Great size for portability.

I had another pair of these but returned them because they were bulking and had little control of the temp.But these are very compact, three easy settings (113 degrees, 123 degrees, and 133 degrees). The battery remaining display is very easy to see. One button operation is easy too. Long press ON, then press again to cycle through the 3 heat settings.I have not tested battery life thoroughly, but example for 113 degrees. 2 hours = 20% of the battery.Any the price is so good which makes it easily 5 stars.
