The best hand warmers 2021
The best hand warmer all round is this rechargeable option from Lifesystems. It features convenient USB charging and can be turned on and off as and when you need it, and it'll deliver up to six hours of heat on a single charge. There are four heat levels to choose from so that you can get things as toasty as you need, and a handy visual indicator will show you how much charge is remaining so you don't get caught out in the cold.
It's ergonomically shaped, pleasant to hold, and has two internal heat plates that deliver a decent burst of even heat from both sides. Finally, it doubles up as an emergency power pack, which is not strictly necessary but surprisingly helpful. Head to our full Lifesystems rechargeable hand warmer review for more of what we thought.
If you want the convenience of a disposable hand warmer in a reusable format, try Hot Snaps. It's a crystallisation-type hand warmer that you immerse in hot water for 10-15 minutes before you go out, then when you need a blast of warmth you can simply click the metal disc in its centre to release the heat.
Be warned, though: they don't stay warm for long: about 50-60 minutes for Pocket Warmers, 30 to 40 minutes for Hand Warmers. So this is not a good choice for lengthy outdoor adventures. But if you want something for short spells out in the cold, this is nicely portable, easy to use and endlessly reusable.
The Zippo hand warmer is shaped like Zippo's iconic cigarette lighter, with six designs to choose from, and works in a similar way. It uses specially-created Zippo fuel that burns slowly and flamelessly, so there's no need to worry about accidentally getting set on fire. And the clever refill system make topping up the fluid pretty easy too. On a full tank, this hand warmer will provide 12 hours of warmth – great if you happen to be heading up the mountain for the day, or planning to go off-grid for a while.
Rather than fiddle about with a hand warmer, why not ensure constant warmth for your hands with these heated gloves? The Aroma Season rechargeable heated gloves pack a pair of 7.4V 3000mAh rechargeable batteries that delivers warmth to your whole hand for up to an hour at a time, after which they'll automatically cut off, presumably to save you from chilblains. You'll get up to nine hours of warmth out of a single charge, though.
They're waterproof, windproof and breathable with three heat settings, and the thumbs and forefingers feature conductive material so that you can still use your phone without getting cold hands. They might be a bit chunky for some, but if you're susceptible to the cold, particularly due to arthritis or Raynaud's disease, they could be exactly what you're looking for.
Celestron is the brand behind many of today's best telescopes and binoculars, and its easy-to-use and versatile hand warmer is similarly impressive and capable of providing continuous heat for up to a massive 12 hours. You can choose to heat up one side, or both. Its aluminium shell is rugged enough for outdoors use, but it’s equally suitable for your winter commute, or standing in the park watching the kids play sports.
And that’s not all. This is also the Swiss army knife of hand warmers, as it also features a flashlight, and works as a portable charger. The 5200 mAh rechargeable lithium ion battery delivers two full charges to most smartphones and MP3 players, and also charges USB-powered cameras.
Most of the best hand warmers are designed to deliver continuous heat over a period of hours, but if all you need is the occasional revitalising blast of warmth then the Grabber might be a better option for you. Designed for occasions such as outdoor sports, hunting, fishing, camping, hiking, jogging and dog walking, these single use, air-activated packs provide fast and immediate heat, starting off at a maximum temperature of 156° F (69° C). They're very easy to use: simply open the packet and expose it to the air. They take less than a minute to warm up, and they’ll stay warm for up to six hours, although the heat intensity will dip from the initial high level. You’ll get best results if you keep them in a pocket or glove.
Don't want to spend much money on the best hand warmer? That's fine; if you're on a budget then you'll find these reusable gel hand warmers from Lifesystems will do the job at a decent price. Pop them in boiling water for a short spell, and the crystals formed from the chemical reaction will turn back to gel. That makes them an absolute bargain over the long term. Be warned that the heat from them doesn't usually last more than about 30 minutes. But if that's all you need, then why spend more?
Hot Hands have been around for a while. And these rectangular shaped, single-use, air-activated heat packs continue to be a popular choice worldwide. Although they don’t emit as much heat initially as Grabber, higher up our best hand warmer list, they do stay warm for longer; up to 10 hours at a time. So if you're going to be out in the cold for lengthy periods, they're an excellent choice at a very low price. (Bear in mind, though, that they're not reusable).
If you need a hand warmer that'll keep on going for absolutely ages, you'll probably want the Peacock, which provides up to 30 hours of heat with just one tank. This liquid-fuel powered hard warmer uses the same fuel as the Zippo lighter, and comes with refilling aids to help you keep it topped up. With its flashy, elegant design, the Peacock Hand Warmer could also make a handy gadget for anyone who suffers from cold digits.
Another top option for anyone who needs a long-lasting hand warmer, the Ocoopa features a whopping 10000mAh battery that'll keep the heat flowing for up to 15 hours, beating some of the best fuel-powered hand warmers and without the smell.

And it's a sleek-looking piece of kit, with a curved body and silicone corner protection to protect it should it get dropped.
