There are many types of hand warmers that would suit your personal needs. Besides, you need to be confident of your decision and that you’re using the system would be comfortable for you. You should consider charging comfort, as well as ease of recharging. In this article, the author sets out the details you need in order to pick a heater, and guides you through making your decision.

How to choose a hand warmer?

Choosing the right hand warmer is not easy since there are several types.

Electric vs catalytic vs chemical model

Three options are offered for those willing to buy a hand warmer. In this way, they will limit their options to an electric, a chemical or a catalytic.

Electric hand warmers

Electric hand warmers are the most common commodity in the industry. They are really realistic. As soon as these are enabled, it is ready for use and what the user then does is to place his hands on them to warm them up. They can easily be turned off when it comes to conservation of resources. This model provides multiple features such as flashlight and external phone battery.

The primary benefit of electric hand warmers is that they are rechargeable, odorless, cheap, and they can be used to charge your smartphone. There are several drawbacks. An electric hand warmer does not last as long as an catalytic hand warmers. Their use of batteries is limited depending on the availability of batteries.

Catalytic hand warmers

Therefore, it is a combustion model. This is the chemical breakdown of the former that releases heat. Catalytic hand warmers were available before electric versions were invented.

While they are less common, they are still valued because of their great function, namely autonomy. It is important to realize that catalytic hand heaters can run continuously for up to 15 hours. A system like this can withstand anything, as long as it’s fuel. The catalytic warmer models are most often intended to have a special design. It is critical that you know that catalytic hand warmers emanate a strong unpleasant smell. It is also risky if you carelessly touch this.

Chemical hand warmers

A chemical hand warmer is a model of hand warmer that does not chemically react – instead, it is based on an exothermic reaction resulting from the oxidation of iron. First, the chemical reaction generates heat. The iron powder is handled in the presence of a suspension of water and carbon. Next, the mixture exposed to the surrounding air is brought inside the combustion chamber. It is in especially ski resorts that these hand warmers are used because of their high efficiency combined with their compact nature.

By being in a compact format, exposed chemical hand heaters are much more portable and can be carried in briefcase, backpack, or even handbag, and taken anywhere in the world. It’s all about ease of use, creating a very attractive interface for the user. This kind of device is at an affordable price among other models. Not like the chemical hand warmers, which can only be re-used, it is likely that the chemical reaction cause the present substance to be formed into an insoluble black residue.

Heat length

The best thing to do when considering taking a hand warmer is to educate yourself about its acceptable temperature range. This autonomy is limited for small devices, no more than a few minutes. For large devices, autonomy is between several hours and several days. As a guide, one should understand that the autonomy time of electric heaters varies between 2 and 8 hours. When heating with a chemical stove, it can take between 6 and 12 hours for the product to reach its targeted temp. Finally, the average time a heaters will reach their temperatures is about 6-15 hours.

Single-use or reusable hand warmer

If it really is true that a reusable hand warmer is more costly than a disposable device of the same kind, it is painfully obvious. It is the number one quality of the philosophy of each model that will decide whether you like that type of system. You are an avid, outdoors-type of person who prefers lightweight, personal vaporizers which you can easily carry around with you. You should think of disposable heaters as another option to consider. If you look for a rechargeable hand warmer that you can use over time, you should opt for a hand warmer that can be used for a tabletop, hands-free combination.


To summarize the point that their ratings vary, it is best to focus on catalytic and chemical hand warmer models that heat better than electric models. It also makes electric devices to heat up slower than conventional devices and fuel and common chemical models. Of course, if the model is resonating at too high a temperature, it can be modified to resonate at a cooler temperature. Regardless of the temperature, opt for a hand warmer that offers a temperature of 50 degrees Celsius or higher.

What are the different types of hand warmers?

Here are the most popular methods hand warmers use to generate heat.

  • Crystallization: This types of hand warmer uses supersaturated solutions of ingredients. Basically, when a gel is properly activated it becomes very opaque, and appears clear. The heat generated by the exothermic crystallization of the gel pack is responsible for the opaque appearance.
  • Lighter fuel: is made by combining petroleum with a platinum catalyst. The two molecules react to produce energy by releasing heat on oxidation.
  • Battery: Small containers that are equipped with a battery convert energy from electrical sources into energy in the form of heat.
  • Charcoal: Charcoal is the most “primitive” hand warmer, which is reflected in the simplicity of its design. Charcoal hand warmers usually have an area where charcoal is placed which produces warmth by combustion.
  • Air activated: Finally, there are heaters that use air as a source. They utilize the oxidation process and catalyze it with a salt.
