What are hand warmers and why do you need one?
Hand warmers are small disposable or reusable units that generate on-demand heat to warm hands and other body parts. Hand warmers are especially useful while hiking and camping in cold weather. They are also pretty useful for other outdoor activities such as hunting, skiing, and fishing. Moreover, if you suffer from medical conditions such as Raynaud’s disease, hand (and toe) warmers can be a lifesaver.
Three types of hand warmers are common in the market – air-activated, catalytic (lighter fuel-based) and electric (battery-powered).
Air-activated hand warmers contain a concoction of iron, cellulose, water, and salt and produce heat from exothermic oxidation of iron when exposed to oxygen in the air. Such hand warmers can last anywhere between 4-12 hours. Such hand warmers are inexpensive, lightweight and efficient. However, they are single-use and cannot be turned off.
Catalytic hand warmers are traditional lighter-fuel based hand warmers. These hand warmers require a flame to initiate warming. Catalytic hand warmers are multi-use and can work for long times till the fuel last (up to 12-15 hours). They, however, provide very little control over the heat levels and are sometimes difficult to turn off.
Battery-powered hand warmers are essentially electrically resistive heating devices that use battery charge to convert electric energy into heat for 6-8 hours. Such hand warmers are multi-use (can last up to 500 recharges) and provide excellent control over heat levels. They are however costlier than other types and may not be as efficient and long-lasting.

How to pick the best hand warmers for you?
Picking the best hand warmers depends on personal preference and factors such as cost and purpose. Once you have an understanding of that, you can keep the following factors in mind while considering the best choice for you or anybody else you are buying it for:
- Type of warmer
- Duration of warmth provided
- Single use or Reusable
Type of warmer
As discussed above, the three most common type of hand warmers used in outdoor activities are air-activated, catalytic (lighter fuel-based) and electric (rechargeable battery-powered).
The air-activated hand warmers are generally single use and once activated, they can provide efficient heating for long times. The air-activated warmers are generally cheaper and come in different shapes and sizes, so they can be also be used for warming other body parts. They are also lightweight enough to fit in gloves, shoes or pockets.
The catalytic (lighter fuel-based) are multi-use/reusable and can last for a long time, up to 15 hours depending upon the fuel supply. They are pretty efficient and provide a high heat level. However, starting and turning them off can be a hassle.
The rechargeable battery-powered hand warmers are also reusable and they generally support recharging for up to 500 times. Once activated, they can provide heat for 6-8 hours. Moreover, they can be easily turned off. Another advantage of rechargeable battery-powered hand warmers is that they can be used as small power banks to recharge digital products such as phones, mp3 players, and digital cameras. However, these hand warmers are not as efficient as the air-activated and catalytic hand warmers and you may find their thermal capacity a little inadequate at times.
Based on the above considerations, you can pick the type of warmers you would like to go with.
Duration of warmth provided
The activation time and the warmth duration provided by a warmer are also important, especially in freezing temperatures.
The air-activated warmers typically take about 4-5 minutes to activate fully on a little bit of shaking in the open air, but can provide warmth for 8-9 hours in most cases and even up to 12 hours in some cases. In addition, air-activated warmers come in pairs, so you can use them for both hands, pockets or gloves.
The catalytic, lighter-fuel based hand warmers take 1-2 minutes to heat up fully after lighting up and last as long as the fuel is available – typically 8-12 hours on full fuel.
In case of rechargeable battery-powered hand warmers, once charged they can be used almost immediately, but are not as efficient and can provide warmth only for up to 7 hours on the lowest setting. Catalytic and electric hand warmers typically have a double-sided thermal surface, so you would have to switch between hands to keep both the hands warm.
Single use or Reusable
As discussed above, air-activated hand warmers are generally single use while lighter fuel based and rechargeable battery-powered hand warmers can be reused multiple times. As a hack, some people tend to use air-activated hand warmers a couple of times by cooling them in ice and then packing them in zipping lock bags, though this is not always advisable.
Lighter fuel-based and battery-powered hand warmers are multi-use, so they can be used more than once. Some battery-powered hand warmers even have different thermal levels – Low (up to 110 F) and High (up to 120 F). In addition, most of the battery-powered hand warmers come with additional features such as LED Flashlight & Emergency SOS Strobe Light. Of course, because of these features and functionalities, battery-powered hand warmers are generally costlier than air-activated warmers.
So based on your preferences, you can pick single-use air-activated or multi-use lighter or battery powered hand warmers.

Cotton Flannel, woolen and fleece fabric are most suitable for this purpose. To use, simply heat the hand-warmers in a microwave for 20-40 seconds and you have some workable hand warmers.
