Disposable hand warmers do the job for an afternoon, then go in the bin. A rechargeable hand warmer gives the same pocket of warmth, then charges back up by USB for the next cold morning. If you walk the dog, wait at the bus stop or stand on the touchline every weekend, here's what to look for.
What to look for
- Where it heats. Some warmers only get hot on one face. A warmer that heats on both sides feels warm whichever way you hold it.
- Battery size. Capacity is listed in mAh. A bigger battery generally means longer warmth between charges, but also a slightly heavier warmer.
- Heat settings. Two or more levels let you turn it down once your hands have warmed up.
- Size and shape. Pocket-sized and smooth is easiest to carry. A lanyard helps if you want it hanging from your wrist or bag.
- Extras. Some hand warmers double as a power bank, so they can top up your phone when you're not using the heat.
Our three rechargeable hand warmers
AeroWarm Rechargeable Hand Warmer: £19.99
A smooth, pebble-shaped warmer that heats on both sides and doubles as a USB power bank (4000mAh). It comes in sky blue, gold, rose gold and silver. It's the one to pick if you want a single gadget for your commute that also rescues a flat phone.
AeroPaw Cat Paw Hand Warmer: £15
A small cat-paw warmer with a 1200mAh battery and two heat levels (about 50°C and 55°C). It measures about 8 x 7.5cm, weighs 82g and comes with a lanyard. It's available in green, pink or white, and makes a fun stocking filler. It's a hand warmer only, not a power bank.
AeroDuo Magnetic Hand Warmers: £33
Two slim, rechargeable hand warmers that snap together magnetically. Split them for one in each pocket, or share one with a friend at the match. They charge by USB (5V), with the cable included.
Bundle offer: buy any 2 hand warmers (AeroWarm, AeroPaw or AeroDuo) and save 15%, applied automatically at checkout.
A few tips
- Charge it fully before the first use.
- If it starts to feel too hot, switch to a lower setting or put it in a pocket rather than holding it against bare skin for long periods.
- Follow the instructions that come with your warmer for charging and care.
