- Reusable Chemically Activated Heat Warmers
- Battery Operated or USB Rechargeable Electric Socks
- Lighter Fuel Hand Warmers
- USB Heated Electric Slipper Foot Warmers
1. Single Use Hand and Toe Warmers
Single use warmer pouches are good for people who only occasionally need to warm up their fingers and toes. A single use pack consists of two chemicals that are inert (stable and non-reactive) until they're mixed together.
The chemicals are held 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 and toe warmers. These are convenient to use and cost less than a dollar each. They can be popped inside your gloves, socks, or jacket pockets. They're also great to help warm up cold wellies on a snowy day. Hot Hands
Single use hand and feet warmers are a good standby to keep in your backpack or car trunk in case of unexpected bad weather. These single use warmers last from 10 to 18 hours depending on the brand bought and on how cold the weather is.

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 in the paragraph above, i.e. an exothermic chemical reaction is used to produce heat as a result of a liquid being turned into a solid. I like the reusable hand-warmer. Although reusable warmers cost a bit more upfront, in the long run they work out cheaper compared to single-use, disposable ones. HotSnapZ
Now for the science bit. Reusable hand warmers produce an exothermic chemical reaction. A solution of sodium acetate crystallizes into a solid, producing 130 degrees Fahrenheit in 5 seconds. The reaction is started by flexing or bending a small metal disc within the pack. As the crystals form, heat radiates from the pouch onto your hands or feet and the warmth produced is effective for several hours.
To reuse the pouch and reactivate the chemicals, the warmer needs to be boiled. The sodium acetate is returned to a liquid form by boiling in a pan of water for 10 minutes. The video below demonstrates how simple a reusable hand warmer pouch is to activate and reactivate.

3. Battery Operated or Rechargeable Heated Socks
If you don't like the idea of carrying chemicals around in your gloves or boots, you may prefer to buy a battery operated hand or foot warmer. These are a similar size to the chemical versions. Many also have the option to choose high or low heat levels. To charge before use, they are connected to a USB charger or a conventional electric wall plug. In use, they draw power from a battery placed within a small pocket hidden in the sock or glove.
Rechargeable heated socks are ideal for keeping your feet warm and cozy inside wellington boots or similar. The s kit is my favorite. It is made of a thick cotton fabric and has three heat settings. There is a small pocket at the top of each sock for a cell battery. When activated, heat spreads throughout the sock fabric. It is your personal foot-shaped electric blanket. Battery operated socks are ideal for outdoor activities like hunting, fishing, hiking, and sporting events. Rabbitroom Unisex Rechargeable Battery Electric Heated Sock
4. Lighter-Fuel Hand Warmers
The Zippo brand, well known for making lighters, also makes hand-warming devices. They work on the same principle as a cigarette lighters. Each hand warmer contains a catalytic burner which uses lighter fuel for combustion and heat generation.
I recommend the . It provides value for money as it is well made and lasts a long time. It is reused by refilling with premium lighter fuel. You need to be careful when refilling as lighter fuel can be dangerous if spilled. There are other cheaper brands on the market, but as the saying goes "you get what you pay for."

The Zippo hand warmer is a small metal box about the size of a pack of playing cards and fits easily inside your glove or coat pocket. The burning fire within the box is completely enclosed and the smouldering heat generated lasts for up to twelve hours.
I purchased 4 of these and I can think of quite a few uses for them. One is going in my car. Another in my backpack. A third I'll keep at the office and the 4th will serve as a backup, if necessary. These had warmers are awesome. Absolutely awesome. They can get quite hot so make sure you don't lose the felt carrying pouch they come with. Filling them with Zippo lighter fluid is simple as is getting the catalytic burner going.— Review of Zippo reusable hand warmers by Amazon customer
5. USB Heated Slipper Footwarmers
Last, but not least I recommend USB heated slippers for a cozy night-in. These fluffy slippers are great as they can be powered up from any USB point (like your laptop or PC.) However, they are not as flexible in use as the other gadgets mentioned as you need to remain connected to a power source while using the device.
My top pick for warm slippers is the One Size Plush . The power cable on these is nearly 2 meters long so you can sit a little distance away from your power source. I wear them every winter to keep my feet toasty and warm. The slippers can be safely worn while they are being charged, so no electricity is wasted waiting for them to be ready to wear. They look just like standard furry slippers and when switched on remain at a steady and comfortable temperature of 42 degrees. USB Electric Heating Slippers
USB slippers are also made as uni-slippers like the pair below. Two feet in one pocket makes you less mobile, but they're a fun accessory for an evening at home with family in front of the TV.
Other Uses for Pocket-Sized Heat Warmers
Pocket-sized or mini heat warmers are designed to be put inside gloves or shoes, but they can also 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 hand warmers in the foot area of your sleeping bag when camping outdoors. They will help keep your feet warm overnight. They will stay hot for longer than a conventional hot water bottle.
3. Use them as a heat pack to soothe sore muscles and aching joints. This works well for for rheumatic and arthritic aches and pains. The small size of hand and feet warmers means they can be placed directly on the target area and can provide instant relief.
4. Warm up a pair of cold slippers with a heat pack before you put them on your bare feet. This works like magic if you have to get out of a warm bed into an unheated room on a cold winter's morning.
5. And I'm sure your pet cat or dog would love a warming heat pack placed in their bed in wintertime too! Your pet will be your best friend forever if you treat them to this luxury.
