    I’m not stranger to cold. When I was in college in Syracuse, New York it felt like crossing the street to get to class. AntarcticaI have built my career by chasing stories where winter is often the main agenda. Swedish Lapland, the high Canadian Arctic, Hokkaido, JapanBuffalo, New York is where I visit my in-laws most often. The last seven years have been by far the most coldest part of my life. Minnesota—a place I adore precisely because locals don’t hide from Old Man Winter. They snowshoe and ski, go ice fishing, and have art festivals in frozen lakes. The right gear is essential: breathable baselayers, balaclavas which make us look like bank thieves, and most importantly, hand warmers.

    I’ve relied on for a long time HotHandsThis classic has its place. I also decided to try some of the other hand warmers available on the market and compare them with my favorite. This winter, I tested a mix of disposable and rechargeable warmers during a snowy week that swung from 27°F to a teeth-clattering –5°F. I used the warmers during neighborhood walks and at outdoor markets. hiking in the woods. chasing my toddler The powdery playground is a great place to test your skills. While many rechargeable models were similar (and even made by the exact same manufacturer in China), some stood out. Here are my picks for the best handwarmers to keep you warm all winter.

    DeeKom

    Rechargeable Hand Warmers

    Heat levels Up to 131°F
    Charging time 4 hours
    Battery life 8–15 hours

    DeeKom warmers were praised for their innovative design and outstanding performance. The thin, remote-like design feels natural in your hand. It keeps your fingers and palms toasty while you grip the stroller handle or steering wheels. They snap together, making them harder to lose. And they reach full heat in about a minute. Five temperature settings make it easy to customize comfort. The 6000mAh battery combined gave me some of the longest running times of any rechargeable that I tested. USB-C charging, an emergency LED/SOS/strobe and a travel-friendly package round out this smart, compact device.

    Pros: Rapid heat, ergonomic oblong shape, long-lasting battery, emergency light
    Cons: The highest temperature setting can be too hot.

    Hot Hands

    Hand warmer Value Pack

    Heat levels Up to 158°F (average 135°F per manufacturer)

    HotHands has been the name of disposable warmers since its inception. These palm-size fabric packets—filled with iron powder, salt, activated charcoal, vermiculite, and other natural ingredients—activate as soon as they’re exposed to oxygen. Then, tear the wrapper open, shake them, and place them in a glove or pocket. These are ultralight, packable and cost less than $1 per pair. ski tripsYou can either go on a city break or get outfitted. larger groups. HotHands claims that they can run for 10 hours. However, in my testing I found them to peak around 4 hours and then gradually cool down. They also took much longer than the 90 seconds some reviewers suggest—more like 15 to 30 minutes—to reach full heat.

    Freshness can affect performance. One pack I stored for an entire year was rock-hard and never warmed, but a fresher pack heated quickly. Still, they’re the easiest size and shape for small hands—my three-year-old loves shaking them to “reactivate” the heat. To avoid burning or irritation, do not place them on bare skin.

    Pros: It is lightweight, safe, child-friendly and easy to use.
    Cons: One-time use and not recyclable

Then, tear the wrapper open, shake them, and place them in a glove or pocket.

However, in my testing I found them to peak around 4 hours and then gradually cool down. They also took much longer than the 90 seconds some reviewers suggest—more like 15 to 30 minutes—to reach full heat.

    The performance can vary based on the freshness of the pack. A pack that I had stored for over a year was as hard as a stone and never heated up. However, a more recent one heated up quickly. Still, they’re the easiest size and shape for small hands—my three-year-old loves shaking them to “reactivate” the heat. To avoid burning or irritation, do not place them on bare skin.

    Pros: It is lightweight, safe, child-friendly and easy to use.
    Cons: One-time use and not recyclable

    Riapow

    Rechargeable Hand Warmers

    Heat levels 104–131°F
    Charging time 4–5 hours
    Battery life Maximum 24 hours (around 10 hours at higher settings for temperatures below zero)

    Riapow’s rechargeable heaters are the perfect option for travelers looking to control their heat output. Smooth and palm-friendly—almost like polished river stones—they warm up in seconds and feature a digital LED display that shows the preferred temperature: 113°F, 122°F, or 131°F. A smart chip integrated into the heater monitors your skin and automatically adjusts temperature levels for safety. It is useful if you are wearing gloves, or moving between indoors and outdoors.

    Each unit is only 2.2 ounces and has a magnetic detachable design. Riapow’s 6000mAh battery is advertised to last up to 24hrs, however in Minnesota during the frigid winter months I found that it lasted closer to 10hrs on the highest setting. These were the most user-friendly heaters for accuracy, comfort and ease of adjustment.

    Pros: Thermostat with excellent temperature control. Lightweight. Safety auto-adjust. Wrist lanyards Included.
    Cons: Battery life is not as good as claimed in extreme cold

    Ocoopa

    Magnetic hand warmers

    Heat levels 100–125°F
    Charging time 3–4 hours
    Battery life 4–8 hours

    Ocoopa UT3 Lite from Ocoopa is the best choice for those who are concerned about sustainability. CarbonFree partners with the company to offset emissions from every unit sold. This makes it a great option for travelers who want to reduce their carbon footprint without sacrificing comfort. Its ergonomic shape—reminiscent of a small computer mouse—fits naturally in the hand, and the flat magnetic sides snap the two warmers together so they’re less likely to disappear into the bottom of a bag or backpack. A single button cycles through three heat settings (100–108°F, 109–117°F, and 118–126°F), and the unit heats in about five seconds.

    The UT3 Lite is not as powerful as some of its competitors but it is easier to use. It charges via USB in three hours and comes with a storage pouch made from velveteen. For travelers who prefer gear that has a bit of personality, it’s available in a range of fun design options including florals.

    Pros: Purchase a carbon offset, magnetic design with ergonomic storage pouch, wrist lanyard included, one button interface.
    Cons: The model doesn’t heat up as much or last as long compared to other rechargeables

    Heat levels 95–130°F
    Charging time 4–5 hours
    Battery life 8-20 hours

    Unihand’s rechargeable warmers work much like the others on this list—three settings, quick to heat, and a magnetic click-together design—but its real standout feature is the color selection. These warmers are available in many colors including champagne, dark, minty, pink, sky, bronze and more. Each unit is powered by a 3000mAh lithium-ion battery, which delivers a good runtime for its size. However, your mileage may vary in colder weather conditions. These are the perfect pair if aesthetics and heat are equally important.

    Pros: Magnets in many colors and styles
    Cons: The grip is not as good as some other options and there is no lanyard included.

    Hot Hands

    Hand warmers with rechargeable batteries

    Heat levels Up to 131°F
    Charging time 3.5 hours
    Battery life 4–8 hours

    HotHands disposable warmers are the most popular, but their rechargeable versions make for an excellent gift due to the polished packaging and brand recognition. Each unit has a 2500mAh battery, three heat settings (96.8–131°F), and a magnetic two-piece design that snaps together neatly. They’re relatively slim—about three-quarters of an inch thick—and heat quickly, with a full charge in just 3.5 hours. They lasted between four and eight hours, depending on their setting. This is not as long as other models, but it is sufficient for most winter outings. The package includes a wrist lanyard, dual charging cable and a 1-year warranty.

    Pros: Branded packaging that is most likely to be gifted, with a limited one-year warranty
    Cons: Charged models have a shorter runtime.

    FAQ:

    What are the best hand warmers brands?

    HotHands is a leader in the industry for over 35 years. DeeKom is my top choice, even though the brand received two “best of show” awards in my testing. This warmer was the most user-friendly of all the warmers that I tried. The size and shape are more comfortable and the heat output is impressive. They also have five heat settings and thoughtful extras such as emergency lights.

    Do reusable hand warmers really work?

    If you live and work in a cold climate or travel to them often—ski trips, winter city vacations—rechargeable warmers are usually the better value. The warmers have multiple heat settings and can be turned on and off to control intensity. The disposable warmers will activate the moment they come into contact with air, and burn out their heat all at once. Disposable warmers can be more cost-effective for larger groups or trips in cold weather. These warmers are also light and easy to carry.

    It’s important to note that Lithium-ion battery performance is not as good in extreme cold. You can expect to see a noticeably shorter heat duration, and a slower activation rate when standing in the cold. TSA requires that battery-powered heaters be packed in carry on bags and not checked baggage.

    How were these handwarmers tested?

    I tested a dozen rechargeable and disposable warmers to find out which one kept my fingers warmest for the longest time. I charged each device before using it, and then followed the manufacturer’s activation instructions. During my testing, I took note of how quickly each warmer heated and how hot they got. Also, when the warmers began to cool. I also evaluated the comfort, usability and battery life.
