Hand Warmers (Buyer’s Guide and Reviews)

When was the last time you felt comfortable, while also feeling cold? The two contradict themselves conclusively.

Most of us realize that. That’s why, when winter comes around, we put on as many layers as physically possible. Unfortunately, winters get so very brutal in many parts of the U.S. One of the most disappointing and defeating feelings in the world is being cold in spite of wearing, a coat, a sweatshirt, a pair of gloves, a hat, a scarf, and several pairs of socks.

Another quite discouraging feeling is living with a chronic condition. Two particularly bad ones are Raynaud’s and arthritis. If you have one of the two, your hands and feet will either be cold or achy for no particular reason other than bad luck.

Thankfully, there is an unsung hero to help us with both the cold weather and the evil chronic conditions that are Raynaud’s and arthritis.

Enter the the hand warmers.

Created by a small-town Japanese inventor in 1923, the hand warmer has become a favorite widget amongst households worldwide; over 45 million sold annually. This 1923 invention is still considered an advanced piece of technology, although, not quite as advanced as the self-driving cars and reusable rockets, of course.

There are three types of hand warmers:

  • Rechargeable – The rechargeable (a.k.a. electric) hand warmers are powered by a battery, which is charged with a USB-to-android cable. They usually have multiple heat settings, as well as extra features, such as a flashlight and a charging plug (compatible with most electric devices out there).
  • Air-Activated – These warmers are disposable. All you need to do in order to use one is to take it out of the wrap. They heat up from coming in contact with oxygen.
  • Catalytic – These heating units need to be filled with lighter fluid and ignited with a lighter. They also need access to oxygen to operate. The catalytic hand warmers are superior to any other types of warmers when it comes to their heat duration, as they could keep you warm for up to 24 hours.

Depending on your needs, desires, and circumstances, one or more of these types of warmers may be useless to you. The contrary is also true.

Here are some pros and cons of each type, so that you may buy the right unit for you, or the person you are gifting to. We’ll start with a brief infographic and go into more detail underneath. Types of Hand Warmers - Infographics

1. Electric/Rechargeable Warmers

Perfect for you if:

You need to use a heating unit for no longer than 6 to 8 hrs at a time.

You plan to use your unit regularly.

You would be pausing and resuming your hand warmer numerous times.

You plan to use the product in your pocket.

Smaller rechargeable units, like the EnergyFlux, may even fit in gloves and scarfs.

You need an easy-to-operate warmer, due to reasons like arthritis or Raynaud’s disease.

Don’t buy an electric hand warmer if:

You have tiny hands.

You won’t have access to electricity for long periods, like when hunting, camping, etc.

You intend to place your it in your boot. Electric warmers are still way too big for that.

Other Info:

To prolong the battery life of your rechargeable warmer, consider the following:

  • Keep the catalytic unit away from direct contact with the cold (like by placing it in your pocket, glove, or pouch if it comes with one).
  • Turn the unit off, while you’re not using it. However, switching it on and off too regularly will reduce the working time of your warmer.
  • Avoid charging other devices with your electric unit or using its flashlight. The additional features will drain part of the battery and affect the heat duration of the product.

Most electric heating units come with a warranty.

Manufacturers of rechargeable units recommend not to use your unit while charging.

2. Air-Activated Warmers.

Buy if:

You want a product that is extremely easy, and non-demanding to use (due to reasons like arthritis pain, and others)

You won’t have access to electricity for long periods of time.

You would need hand warmers only for a few days/ weeks out of the year.

You want your product to be small and soft so that you could place it in your boot, glove, etc.

Don’t buy if:

You are allergic to any of the contents of the air-activated hand warmers.

You need to use a hand warmer regularly.

You need your hand warmers to be 100% reliable. Sometimes, in a box of air-activated warmers, a few of the pairs may be faulty.

Other Info:

You may pause (for no longer than a day or two) and reuse air-activated units by placing them in a Ziploc and sucking all the air out of the bag.

If you wish to use your heating unit in an oxygen-deprived space, like your boot, be sure to take the warmer out of the wrap and let it reach its highest temperature, before placing it there. It takes about 20 minutes for this to happen.

If you have arthritis in your hands, or they are just numb from the cold, you will need scissors to open the wrap of the warmers.

3. Catalytic Hand Warmers.

Buy if:

You need your warmer to last long periods at a time (12-24 hrs).

You want an elegant accessory, as well as a hand warmer.

You like large length and width of the rechargeable warmers but dislike how thick they are (especially if you will wear it in your pocket).

You don’t mind purchasing and handling lighter fluid and lighters.

Don’t buy if:

You have arthritis in your hands, and refilling and igniting the unit would be difficult for you.

You will need to refill your warmer in extremely cold conditions; your hands may go numb and make it hard for you to do so.

You don’t feel like spending money on lighter fluid regularly.

You’d like to place the catalytic unit in your shoe.

Other Info:

To turn off a lighter fluid hand warmer, you must place cut its oxygen flow. One way to do that is to put it in a ziplock bag, suck the air out and seal the bag.

Usually, the catalytic units get too hot and need to be placed in a pouch (which most products come with) when used.
