Our pick
Best overall: BIUYO Rechargeable Hand Warmers, 2 Pack, Magnetic Design (£15.99). Two pocket-sized electric hand warmers that work separately or snap together as one double-sided heater. The colour is grey, the listed material is plastic (the bullet points mention an aluminium alloy and flame-retardant ABS build), and the box includes a charging cable and a user manual. The listing gives a 1 year warranty.
What the Amazon UK listing says
Two-in-one design: the two warmers have a magnetic snap, so you can use them together as one double-sided warmer or apart, one for each hand or one to share.
Battery: 6000mAh in total, listed as 3000mAh per unit. The listing says up to 12 hours of continuous warmth on a single charge. Run time on any heated product usually depends on the heat level you use, so expect less on the highest setting unless the manual says otherwise.
Charging: a dual USB-C cable is included and the listing says both units fully recharge in about 3 hours. A USB plug is not listed as included.
Heat levels: 3 settings, listed as low 40 to 45°C, medium 48 to 52°C and high 53 to 60°C. The listing says a chip keeps the temperature steady and prevents overheating.
Size and weight: each warmer is listed at 75 g and 0.8 inches (about 2 cm) thin, small enough for a coat pocket, glove or handbag.
Protection: the listing says there is protection against overcharging, over-discharging, overheating and short circuits. The product title also says CE-certified.
Who it is aimed at
The listing suggests it for golf, hiking, football matches, fishing, camping and cold commutes, and as a winter gift. At £15.99 for two units it sits at the budget end for rechargeable hand warmers, so it may suit someone who wants a pair to share or one for each pocket.
What BIUYO claims, and how to read it
The listing says these are ideal for Raynaud's syndrome relief and arthritis comfort. That is the seller's own claim. We have not tested it, and a hand warmer is a comfort product, not a medical treatment. We have also left out the listing's comparison with other brands because we cannot check it.
What the NHS says about Raynaud's
The NHS says Raynaud's is where blood stops flowing properly to your fingers and toes, and that you can often treat the symptoms yourself by keeping warm. It advises keeping your home warm, wearing warm clothes in cold weather, especially on your hands and feet, and trying to avoid sudden changes in temperature. See a GP if symptoms are very bad or getting worse, are affecting your daily life, are only on one side of your body, come with joint pain, skin rashes or muscle weakness, or start for the first time when you are over 30. A child under 12 with symptoms should also see a GP.
What the NHS says about arthritis
For osteoarthritis, the NHS says applying hot or cold packs to the joints can relieve pain and symptoms in some people, alongside exercise, pain relief and keeping to a healthy weight. Ask your GP or physiotherapist whether heat suits you.
Safety points before you buy
Heat: the highest setting is listed at up to 60°C. Start on low, do not hold a warmer against bare skin for long periods, and stop if your skin becomes red or sore. Take extra care if you have reduced feeling in your hands, for example from diabetes or nerve problems, because you may not notice a burn. Ask a GP or pharmacist first if that applies to you.
Children: supervise children using any heated product and keep to the lowest setting.
Sleeping: do not fall asleep holding or wearing a heated warmer.
Batteries: these contain rechargeable batteries. Use the supplied cable, do not charge them unattended overnight or under a pillow, and stop using a unit that swells, gets unusually hot while charging or is damaged.
Flying: GOV.UK says some airlines have different rules on electronic items and batteries, so check with your airline before you pack these.

Frequently asked questions
Are rechargeable hand warmers safe?
This BIUYO pack lists protection against overcharging, over-discharging, overheating and short circuits, and a top heat setting of up to 60°C. As with any heated, battery-powered product, start on the lowest setting, use the supplied cable, stop using a unit that swells or is damaged, and take extra care if you have reduced feeling in your hands.
How long do rechargeable hand warmers last?
The Amazon UK listing says up to 12 hours of continuous warmth on a single charge from 3000mAh per unit (6000mAh across the pair). Run time usually drops on higher heat settings, so check the user manual for the figure at each level.
How long do rechargeable hand warmers take to charge?
The listing says both BIUYO warmers fully recharge in about 3 hours using the included dual USB-C cable.
How hot do rechargeable hand warmers get?
This model has 3 heat levels, listed as 40 to 45°C on low, 48 to 52°C on medium and 53 to 60°C on high. Start on low and check your skin, especially if you are using them for long periods.
Are hand warmers good for Raynaud's?
The NHS says you can often treat Raynaud's symptoms yourself by keeping warm, including wearing warm clothes on your hands and feet and avoiding sudden temperature changes. A hand warmer can be one way to keep hands warm, but it is not a treatment. See a GP if symptoms are very bad, getting worse or affecting your daily life.
Can you take rechargeable hand warmers on a plane?
GOV.UK says some airlines have different restrictions on electronic items and batteries, and that devices should be charged before you travel. These warmers contain rechargeable batteries, so check with your airline before you fly.
