For those that love exercising outdoors year-round, hand warmers can be the difference between feeling uncomfortably cold and being ready for anything in the winter months. Hand warmers come in a variety of forms, including disposable, battery-powered handheld units, and heated gloves and mittens. The type of unit you choose will depend on your preferences and activity level.
“Hand warmers can actually be used to heat up more than just your hands. Use them to heat up a sleeping bag, water bottle, camera batteries, or even your phone if it turns off because of the cold temperatures. You can also place these on your femoral or carotid arteries to help warm up your whole body in an emergency. If you’re using them on a sensitive area, put them in a sock so you don’t get burnt,” Alexandra Roberts, Wilderness First Responder and member of Androscoggin Valley Search & Rescue in the White Mountains of New Hampshire, says.

May be too bulky for some
The warmer charges to full battery in under four hours, and we love that it can also charge your phone. Weighing in at 7 ounces, it’s light enough to carry while exercising. However, it’s too large to fit in a standard running glove or mitten, so you may need to keep it in a jacket or pants pocket instead.

What the Experts Say: “I’ve tried all brands of disposable hand warmers, and these stay the hottest for the longest amount of time. I am an avid backcountry skier, climber, and hiker, and I never leave home without at least one pair in my pack during the cold months.”
They’re also the best option when you can’t recharge a battery, like during a camping trip. Hot Hands are air activated and TSA-approved. But they do take 15 to 30 minutes to heat up, which is longer than other warmers on our list.

For a reusable option that doesn’t require electricity, we recommend Zippo’s Refillable Hand Warmer. Because it runs on lighter fluid, once you fill it up and light it, it stays warm until the fluid runs out about 12 hours later. This warmer is a great option for cold weather walking or camping, when you might not have access to electricity, since it’s easy to refill on the go.

How We Selected the Best Hand Warmers
To select the best hand warmers, we first interviewed Alexandra Roberts, an outdoor enthusiast and wilderness first responder. Roberts also has Raynaud’s syndrome, which can cause pain, tingling, or numbness in someone’s fingers or toes when they are exposed to cold. As a result, she has tested out many hand warmers on the market and offered her expert advice on which features every quality hand warmer needs.
Final Verdict
Ocoopa’s Rechargeable Hand Warmer is our top pick if you’re searching for a lightweight hand warmer with a long battery life. It has a phone charger and can fully charge in just a few hours, making it a reliable choice for walking or running outdoors.
For a budget-friendly option, we also recommend Hotsnapz’ Reusable Hand Warmers. User-friendly and easy to reset, these tiny warmers are thin, portable, and provide heat for over 30 minutes.
Then, we researched dozens of hand warmers from the most trusted and popular brands. We considered the type of warmer, the quality, and the price. We also evaluated them based on size and weight, heat duration, heat source, maximum temperature, and how much time they take to charge.
What To Look For in a Hand Warmer
Heat Source
There are two main types of hand warmers: disposable and reusable. Disposable options usually heat up when they are exposed to air, and many can last a full day, depending on the outside temperature. Once they are cold, they can’t be reheated. Disposable options are great for when you won’t have access to a charger, or as a backup in a pinch.
Reusable hand warmers typically feature a rechargeable battery. There are hand held warmers, like Zippo’s HeatBank Rechargeable Hand Warmer, and heated gloves or mittens, like Outdoor Research’s Lucent Heated Sensor Mitts. Handheld warmers are helpful for outdoor activities where you aren’t using your hands or can stop to take breaks. Heated gloves or mittens are a good choice for cycling or skiing, when you need warmth while exercising.
“If the duration of time isn’t of any concern to you, electric hand warmers are the way to go. These help save the planet as well—for example, if you’re going out on a dog walk and don’t need 10 hours of warmth, heated gloves are perfect for this use,” Roberts says.
Heat Duration
“The best hand warmer is the one that stays hottest for the longest amount of time,” Roberts says. Hand warmers may hold heat for anywhere from 30 minutes to 15 hours. For shorter activities like walking, a warmer with a shorter battery life may be enough. However, if you’re headed out for a full day of downhill or cross-country skiing, snow shoeing, or hiking, you will want to choose a hand warmer that stays warm for several hours, like Celestron Elements’ Firecel+.
Size and Weight
The size and weight of hand warmers can vary. Larger, heavier warmers may provide longer heat times, but can be difficult to carry while staying active. Smaller, lighter weight options (like Survival Frog’s Rechargeable Hand Warmer) may be more practical for activities like running or skiing.
Maximum Temperature
Hand warmers can grow as hot as 95 to 150 degrees Fahrenheit, depending on the brand and type. Some, like Ocoopa’s Rechargeable Hand Warmer, also have settings that allow you to adjust the level of heat, so you can find one that feels comfortable and not too hot. Most electric hand warmers and gloves have three levels of heat, but some have up to six. Be mindful of how hot your hand warmer is getting over time to avoid burns.
Additional Features
Many handheld electric hand warmers can also act as a device charger in a pinch. Some also come with a flashlight, which may be helpful in certain low-light situations. Choose a warmer that meets your needs, depending on the outdoor winter activities you enjoy doing the most.
Why Trust Verywell Fit
An avid runner and downhill skier living just outside of Boston, Sarah Anzlovar, MS, RDN, LDN, has tested and used many different hand warmers over the years. When she’s on the slopes, she prefers Hot Hands’ Hand Warmers for their convenience, size, and heat duration. For colder runs or dog walks, she likes a heated glove, like Day Wolf’s Heated Glove Liners.
Frequently Asked Questions
- What is a hand warmer?
- Hand warmers are small packets or devices that provide heat and can be used to warm your hands. Most hand warmers are designed to be held in your hand, though some can fit in a glove or a pocket. Others, like come built into gloves and mittens.
- How do hand warmers work?
- “There are a handful of types of hand warmers on the market today, but the most common ones you will see are air-activated, supersaturated solution (snap and heat), and battery-powered. Air-activated hand warmers work when they are exposed to air,” Roberts says. Air activated hand warmers may include iron powder, water, salt, activated charcoal, and vermiculite, among other ingredients. When mixed together and exposed to air, these ingredients oxidize and produce heat.“Electric hand warmers work by using a little heater inside of the casing that you slip into your glove or hold,” Roberts says. These rely on a battery that must be recharged regularly. “The supersaturated solution type has a little metal disc inside. When bent, small pieces of metal are released into the solution, which causes the solution to crystallize and produce heat,” she adds.
- How long does a hand warmer last?
- It depends on the warmer. Disposable hand warmers may stay warm for up to ten hours. Battery-powered options can last up to 18 hours on a full charge. And reusable hand warmers usually last for under an hour.
