5 Gadgets to Keep Hands and Feet Warm (Winter 2018)
Five Pocket-Sized Feet and Hand Warmers
- Single Use Hand and Feet Warmers.
- Reusable Chemically Activated Heat Warmers.
- Battery Operated or USB Rechargeable Electric Gadgets.
- Lighter Fuel Hand Warmers.
- USB Heating Slippers.
1. Single Use Hand and Feet Warmers
Single use warmer pouches consist of two chemicals that are inert (stable and non-reactive) until they're mixed together. They are packed separately in sealed compartments within a larger cover. To activate the pack, you simply break the seal between the two compartments and an exothermic chemical reaction occurs. Exothermic is a scientific term that means heat is produced as a by-product of the chemicals mixing together.
There are many commercially produced single use warmers available. I particularly like hand warmers. These are convenient to use and cost less than a dollar each. They can be popped inside your socks too to use as toe warmers. Hot Hands
If you like doing DIY, you can make single use hand warmers using Calcium Chloride and water. The video below shows you how.

2. Reusable Chemically Activated Heat Warmers
If you're likely to use hand or feet warmers on a regular basis then it's cheaper to buy reusable ones (and better for the planet.) Reusable chemically activated warmers work on the same principle as described above, i.e. an exothermic chemical reaction is used to produce heat as a result of a liquid being turned into a solid.
Different chemicals are the basis of these reusable, more environmentally-friendly versions. A solution of sodium acetate crystallizes into a solid producing 130 degrees Fahrenheit in 5 seconds. Activation is carried out by flexing or bending a small metal disc within the pack. The sodium acetate is returned to its liquid form by boiling it in a pan of water for 10 minutes. The video below demonstrates one of these being activated.

3. Battery Operated or Rechargeable Electric Gadgets
If you don't like the idea of carrying chemicals around in your bag, then you may prefer battery operated hand and feet warmers. These are a similar size to the chemical versions and have the benefit of having the option of variable heat levels (usually high or low heat). They can be connected to a USB charger of a conventional wall plug so they are convenient for travelers.
You can also get socks designed to keep your feet toasty warm inside wellington boots or similar. are great if you need to be outside in winter. They have a tiny pocket in which you put a small cell battery. The warmth is spread through the sock fabric like a foot shaped electric blanket. They are ideal for outdoor activities like hunting, fishing, hiking, and sporting events. Lectra Wader Sox
4. Lighter-Fuel Hand Warmers
The Zippo brand, well known for making lighters, also makes a hand warmer device. It works on the same principle as its cigarette lighters. It consists of a catalytic burner which needs lighter fuel for combustion. It is a small metal container that fits inside your glove or pocket. It is reusable and refillable. It provides a safe, enclosed real fire and, depending on which size you use, it provides heat for up to twelve hours.
5. USB Heating Slippers
Last, but not least are USB heated slippers. These are great as they can be powered up from any USB point (like your laptop or PC.) The power cable on the is nearly 2 meters long so you can sit a little distance away from your power source. The slippers can be safely worn as they are being charged. They look just like standard furry slippers and when switched on will remain stay at a cozy temperature of 42 degrees. One Size Plush USB Electric Heating Slippers
USB slippers are also made as fun uni-slippers like the pair below. Two feet in one pocket makes you less mobile, but good for an evening in front of the TV.
Other Uses for Pocket-Sized Heat Warmers
Although mini heat warmers are designed to be put inside gloves or shoes they can be used for many other things. Here are a few suggestions.
1. Use them to dry out wet walking boots overnight. Put one in each damp boot before you go to bed. Your boots will be warm and dry when you wake up next morning.
2. Place a couple of warmers in the foot area of your sleeping bag when camping outdoors. They will help keep your feet warm overnight.
3. Use them as a heat pack to soothe sore muscles and aching joints.
4. Warm up a pair of cold slippers with a heat pack before you put them on your bare feet.
5. And I'm sure your pet cat or dog would love a warmer pack placed in their bed in wintertime too!
Cosy Fingers and Toes Make You Feel Better
Your hands and feet get cold in winter because your body prioritizes blood flow to vital organs like the heart and lungs to keep you alive. This leads to a reduction in blood flow to the extremities (i.e. hands and feet). Wrapping up warm helps prevent heat loss in fingers and toes.
