  • Good price.
  • Tried and trusted.

It can reach up to 131 degrees on the highest setting, heating up in just three seconds and lasting between four to eight hours depending on use and conditions.

  • Comfortable.
  • Choice of colors.



A really nice idea that works well for the most part. You can’t go wrong for the price and a decent option for casual use.

Zippo Refillable Hand Warmers

Review: As a brand, Zippo needs little introduction, and their portable hand warmers are arguably the market leaders.

Much like their famous lighters, these all-metal warmers use a butane reservoir to power up to twelve hours of flameless heat with a catalytic burner.

Six-hour versions are also available and they all come with a soft pouch for comfortable use.


  • Another company you can trust.
  • Multi-use.
  • Slim, compact design.


  • Requires fuel and igniter to operate.
  • Can’t be turned off once lit.


This virtually odorless design is one of the best hand warmers for hunting, but it’ll hold its own in just about any situation.

How it actually works might put some people off though – see the FAQ below.

Reusable Heat Packs by Snappy Heat

Review: Rocketing to 130 degrees inside three seconds, one of the great advantages of these heat packs is that they are reusable.

Once activated, they’ll last between 10-15 minutes, and to reuse you simply boil them until the internal crystals have liquified again.

Up there with the best chemical hand warmers, you can buy.


  • Versatile shapes.
  • Reusable.


  • Heat doesn’t last long.


If you’re needing a quick 15-minute heat boost then these packs are a great option, but for a longer lasting hand warmer you’ll need to look elsewhere.

It offers three temperature settings and can last up to eight hours. You’ll be able to give your smartphone at least one full charge from the power bank, too.

  • Lightweight.
  • Choice of colors.


  • Like all these power bank warmers – you can’t charge and heat at the same time.


A nice looking hand warmer that would make an ideal gift for a loved one.

HotSnapZ Hand Warmers

Review: These HotSnapz are contenders for the best reusable hand warmers and are a significant improvement on similar products because of they last longer.

The green pocket warmers will go for about an hour, while the red hand warmers will last for up to 40 minutes.

Boil them for 10-15 minutes to return to their liquid state and you can use them again and again.


  • Useful pocket and hand size options.
  • Eco-friendly.


  • Still won’t last as long as electric warmers.
  • Takes a minute or two to heat up.


A good chemical hand warmer that’s reusable and lasts long enough to give your frostbitten fingers some relief.

Again, if you’re outside for longer periods or need continuous heat, it won’t be what you’re looking for.

PISEN Rechargeable Hand Warmer

Review: Another version of the popular pebble design, this warmer is a step up from previous models.

An award-winning unit, it has a more powerful battery and will maintain 122 degrees for three to five hours. It’s a fuller, more rounded device that should be more comfortable for most hands.


  • Doesn’t get too hot.
  • Heat is well distributed.


  • Slightly on the bulkier/heavier side.


A well built, stylish, quality hand warmer that offers decent battery power.

BigBlue Rechargeable Hand Warmers

Review: One of the more powerful 3-in-1 devices out there, this hand warmer will charge your phone roughly two times and give you heat for up to 4.5 hours.

The LED flashlight is very useful and the 10000 mAh battery packs a punch.

Big Blue make quality solar chargers, although I’m not entirely sure why this device comes in red.


  • Great battery power.
  • Reputable company.


  • A choice of colors would have been nice.


Probably one of the best electric hand warmers and power banks available. The 10000 mAh battery power really makes a difference here.

A reputable sporting goods company, UA are clearly marketing this at anyone who plays sports outside in freezing conditions, but it’ll work just as well for any exterior activity.

A Handy Buying Guide to Hand Warmers

If you didn’t realize just how confusing the world of hand warmers really is – then the following sections are for you.

Primary Use

Before making a choice of the type of hand warmer that would suit you best, first, you need to identify what you’re going to be using it for.

If it’s just going to be a once off, or you don’t think you’ll use an electric model much throughout the year, consider picking up some spare disposable warmers – or the gel reusable kind.

For more regular use, or if the product will be used for frequent pain relief and health issues – you’ll want a rechargeable device which will save you money in the long run.

And if you’re frequently out in the field, camping, hiking, hunting, fishing or any kind of sport; then heated gloves or mittens might be the way to go.

Chemical Hand Warmers

Hothands, Snappy Heat and Hotsnapz (to name but three brands) utilize a chemical reaction in their hand warmers – which usually comes in a sachet of colorful liquid.

But don’t worry, it’s perfectly safe, non-toxic and environmentally friendly.

Unless of course, it says otherwise – which it shouldn’t – so steer clear if it does.

They can be either disposable (Hothands) or reusable (Snappy Heat and Hotsnapz), and again it’s up to you to purchase the best one for your needs. Obviously, the reusable versions will be a little more expensive.

Each offers their own advantages and disadvantages, with heat lasting longer in some, achieving peak temperature in shorter times and/or generally being a hotter product.

Check the reviews above for the specs of each.

Electric Hand Warmers

Supplied with a USB cable, you simply connect these hand warmers up to the mains and give them a full charge.

Then, depending on the make and model, it will give you double-sided heat at the touch of a button. Most models will offer more than one temperature setting.

Again, how long they last and how hot they become is determined by the quality of the product, as well as the conditions you use it in.

But most rechargeable hand warmers should reach around 130 degrees in under a minute – some as fast as a few seconds.

How long it takes to charge will vary too, so check the specs again to make sure you’re not waiting too long. Electric models are among the best reusable hand warmers 2023.

Fuel Hand Warmers

Liquid gas – in the form of butane lighter fluid – is used to power a fuel-only hand warmer.

Zippo has the market cornered in this regard, and they create some of the most popular and reliable products for this type of warmer.

It works by filling a plastic reservoir with fuel and then dousing the cotton swab at the top of the metal casing – similar to that at the bottom of a regular Zippo lighter.

By igniting this tinder, the device will convert it to heat by means of a simple but effective catalytic converter.

In spite of it being flameless, some people might be a little uneasy using such a device in their pockets.

The only real downside I can see is you still need to carry a lighter or matches to “turn it on.” It’ll last for hours when it gets going, though.

Muff Hand Warmers

The kind of warmer that uses no power source, save your own body heat.

Usually lined with thermal retaining materials such as faux fur, sheep’s wool or other insulated fabrics, you simply stuff your hands in and keep them there until you can feel them again.

Some models (like the version included in my review) include pockets or compartments in which you can add another hand warming device like any of those listed above.

The obvious advantage is that you don’t need to charge or burn anything, but they might not be the best in genuinely arctic conditions.

Like in the Midwest, for example…

Microwavable Hand Warmers

Filled with rice or perhaps another synthetic material, these warmers can come in a variety of shapes and sizes for use all over the body – not just the hands.

Pop them into the microwave, give them a 30-second boost or so and they’ll heat you up and keep you toasty in no time.

One of the best options for people who aren’t going to be leaving the house and/or suffer from health issues – such as poor circulation or arthritis.

Not much good in the great outdoors.

Electric Heated Gloves or Mittens

Electric gloves or mittens are an excellent way to keep your hands that extra bit warmer – even in sub-zero conditions.

Charge the battery at home, turn on in the field and let the current flow around the circuit ensuring your hands keep frostbite at bay.

Good quality gloves and mittens won’t be cheap, but they’re perfect for winter sports or people who spend a lot of time outdoors during the colder months of the year.


You’ll notice that the main “extra” offered with electric hand warmers is that they often double as a power bank.

How effective these are will be determined by the size of the battery and the type of device that you’re intending to charge.

It should be noted that you can’t warm your hands and charge something at the same time.

Flashlights are included in some models – which can be surprisingly bright and useful when you’re fumbling around in the dark.

Size and Weight

Not to be overlooked is the size and weight of the hand warmer.

Will it fit into your pocket? Will it fit comfortably into your hand? Will it slide easily into a glove? Is it pleasant to sit on and warm your bum?

For the most part, hand warmers are ergonomically designed to fit into the contours of your hand, but it’s worth double checking dimensions because some are more cumbersome and bulky than others – and you might want to warm more than your hands.


One thing you might notice in my review is that the prices between hand warmers don’t vary that wildly. For a decent electric device, you won’t be breaking the bank.

However, as mentioned above, good quality mittens and gloves will stretch the wallet a little further.

I personally wouldn’t take a chance on anything cheap if this was the type of warmer I was looking for.

And the cost of disposable warmers will depend on how many you want to stock up on. A bargain initially, but you might be throwing money down the drain in the long run.

Are Hand Warmers Safe?

Probably the number one concern for people looking to dip into the hand warmer market, the general answer is – yes, they are.

Like any product, you have to use it correctly and stick to the safety advice in order to not have accidents or issues.

For people who have sensitive skin, such as the young or the elderly, heat injury is often a worry. But most devices will come with protective pouches or pockets, and manufacturers advise that you don’t put any warmer directly onto the skin anyway.

Even so, while they get quite hot, hand warmers won’t injure anyone given proper use. And you’re never going to get an electric shock from the glove or mitten warmers.

Obviously, take care when charging any electrical device. Sticking your fingers in the socket isn’t safe at all.

See below for a description of the chemical warmers.

How do the Chemical Warmers Work?

Another concern is what exactly is the reaction going on inside the disposable/reusable gel hand warmers? When you mention the word ‘chemical,’ people tend to freak out.

It’s a non-toxic, non-harmful, natural and eco-friendly reaction between the ingredients inside the sealed bag.

These ingredients are most likely to be iron powder, water, salt, activated carbon, and vermiculite. When exposed to air, they react in a fast exothermic oxidation process that provides the heat.

Instead of iron, a reusable warmer will utilize a supersaturated solution of sodium acetate that releases heat as it crystallizes. It can be re-activated by boiling for 10-15 minutes until it returns to a liquid again.

Regardless, ‘chemical’ warmers are not going to melt anyone’s hands off, even if the bag is somehow punctured.

Keep out of reach of young children and certain millennials though – they don’t look too dissimilar to Tide Pods…

How Long Does the Heat Last and How Hot do they Get?

This will depend on a variety of factors.

  • The type of hand warmer you’re using.
  • The quality of the product.
  • The current temperature and conditions.
  • What heat settings you’re using (if there are any).

Obviously, you’re going to want to select a hand warmer that will get the job done – so check the manufacturer’s specs again to make sure it’s going to last as long as you need it to.

Can I Take Hand Warmers on an Aircraft?

While the final decision will be with your carrier/the TSA, most hand warmers are safe to travel with. The main exception will be fuel reliant hand warmers, where you’ll likely be asked to check the device in – particularly on international flights.

Make sure you inquire before departure – it’s better to be safe than sorry.

Do Hand Warmers Smell?

Hunters especially will be concerned with this, given that it might frighten a potential target away.

Fuel warmers are “virtually” odorless, with some users reporting only the faintest smell of lighter fluid – and even then it’s barely noticeable.

Other types of warmer don’t smell at all.

The microwave rice packs can give off a bit of a niff – but you’re unlikely to be chasing a deer with your hands stuffed in one of those.

Can I Make My Own Hand Warmers?

If you’re feeling that way inclined, yes, you can! You can do anything you set your mind to.

But rather than allow me to waffle on about this basic science experiment, check out the useful video below if you want to take things into your own hands…
