The winter may be cold this year, with La Niña effects varying from place to place. There’s a chance Earth’s seasons may also be out of sync causing variable weather. However, when those cold months do arrive, you’ll need to stay warm. You can pile on layers, jackets, and extra clothing, but it also helps to have some handy gadgets — like a USB-powered hand warmer. More specifically, this $18 winter-ready two-pack of Unihand AI hand warmers is just the kind of thing you, and your loved ones, might need. They’re dual hand warmers that offer rapid heating between 95 degrees and 130 degrees Fahrenheit. You leave them in your pocket until you’re ready to warm up those palms. They work great when you’re going to be outdoors for an extended period, such as while skiing, hunting, or camping.
According to the listing, these warmers have a “next-gen” AI chip to help protect from overheating, over-currents, over-charging, and over-voltage. The listing also claims they’re CE/FCC certified for user safety. The batteries should last between eight and a half and 20 hours of use, depending on the temperatures you select, which is great for long, cold days outside.
While some reviews do mention they can get “extremely” hot, possibly even hotter than the range provided, they still work well at warming your hands. In addition, some others seem to think they make the “perfect gift” for a loved one, especially if they’re spending time out in the cold. The price is also great. While not the same brand, hand warmers did appear in our list of USB gadgets smart owners should have for fall. It makes sense for that to carry over into winter with something portable like the Unihand hand warmers.
What reviewers have to say
With their supercar-inspired designs, USB-charging capabilities — they come with USB-C to USB-A cables — suitable operating temperature range, and easy to use setup, it makes sense why these are popular. They also come in a myriad of colors from all-black to champagne, dark green, and beyond. That’s fantastic if you’re buying several bundles to gift to others and want everyone to have a different style.
As for what the community thinks, they currently have over 6,000 reviews on Amazon with a 4.5 star rating. 80% of those reviews are five stars, 13% are four stars, and 4% are three stars. Customers seem to agree they’re reliable, work well, offer great battery life and warmth, and are a good travel or portable size. Some of the negative reviews do mention they get too hot, which tracks with even the positive reviews.
Some of the other reviews state the batteries didn’t last as long as promised and that the devices didn’t last longer than a single season. While most of the experiences seem to be glowing and positive, it still helps to consider the other side of the equation. Temperature-related USB gadgets seem to be a big hit for improving your daily life, whether you’re talking about hand warmers, a mug warmer, or even a mini fan when it’s hot. They’re also phenomenal stocking stuffers for friends and family, and they would also probably make an exciting surprise in white elephant.
