Rechargeable hand warmers
Two warm pebbles for your pockets that click together into one. Pick a color, charge them over USB-C, and choose Low, Medium or High.
130 °F on High · 20 h on Low
Ten colors, one pair
The thermostat
Each press of the orange button moves the pair one level up. The number of red lights tells you where you are.
95-107.5 °Fup to 20 hours
Low keeps your fingers comfortable through a long, still stretch: a tree stand at dawn, a desk by a drafty window, the second half of a game. It is the level that reaches 20 hours.
104-118.5 °Fup to 14 hours
Medium is the walking level. Between shots on the course or on a commute, it warms your hand each time it goes back into the pocket and still lasts most of the day.
118.5-130 °Fup to 8.5 hours
High is for the first cold minutes, a windy lift or numb fingers after unloading the car. Use it to warm up, then step down to make the charge last.
The hours are upper figures for each level. Wind and cold air shorten them, and so does switching on and off. That is the UNIHAND way: printed figures, never promises. How to pick a level.

Before you choose
The UNIHAND studio gets these six questions most often.
Long, still hours want Low and its 20 hours. A walk, a round or a commute is a Medium day.
Each unit is 3.46 by 1.84 inches and under an inch thick. Check that your coat or pant pocket takes it lying flat.
One box warms both your hands, or your hands and the hands of the person next to you.
A warmer works best held in a bare or lightly gloved hand inside a pocket, between the times you need your fingers.
Plan a full charge at room temperature the evening before, with the USB-C cable from the box.
All ten colors heat the same. Pick the one you will spot in a bag, or the one the person you are buying for would pick.
The 2-in-1 idea
One unit in each coat pocket, or one per glove hand. Each is 3.46 inches tall and weighs 0.15 lb, so it disappears into a jeans pocket.
Put the two back to back and they join into one palm-sized warmer that heats all the way around your hand.
Hand one to the person next to you on the bleachers or at the market. Each half runs on its own charge and its own level.
Every color in the UNIHAND hand warmer range is built this way, with a USB-C cable in the box to charge both halves. How to charge and join them.
Our story
That line is printed on our store banner, and it is the whole brief we gave ourselves. UNIHAND started in 2022 with one question: why does the warm part of a winter day have to end when you step outside?
Our answer fits in a pocket. Two small rechargeable warmers, shaped to the curve of a palm, with a sensor in each that reads the warmth between the shell and your hand and holds the level you picked. We call it the AI chip. It is a thermostat, not a gadget that learns.
Since then the pair has gone to tree stands and golf courses, to Christmas markets and school pickups, in ten colors. You choose the color, we keep the warmth honest: three levels, printed temperatures and hours, and nothing promised that a small battery cannot deliver.
The people at UNIHAND still write every page of this site from those printed figures.

HuntingHand warmers for huntingIn a stand or blind your hands cool during the hours you sit still. Low holds 95-107.5 °F for up to 20 hours on one unit, the second unit waits switched off in an inner pocket, and the darker shells stay out of sight next to camouflage.Heat levelsHeat levelsLow, Medium and High run from 95 to 130 °F, one red light per level. Low lasts up to 20 hours, High up to 8.5, and those are ceilings that cold and wind bring down. Choose by where the warmer sits and how long the cold lasts.
GolfHand warmers for golfGolf on a cold morning asks for feel in your fingers at the exact second you swing. A UNIHAND unit in each front pocket warms your hands on the walk between shots. The second unit can go to your partner in the cart, and the golf balls stay in a pocket of their own.
SkiingHand warmers for skiingThe chairlift is where a ski day turns cold. Keep a UNIHAND unit in an inside pocket and hold it on the ride up. Give the second one to the person beside you, and charge both at the lodge rather than in the car park.

Choosing
Air-activated packs, lighter-fluid warmers and rechargeable pairs make heat three different ways. What each runs at, how long, and what is left over after a season.

Low, Medium and High as fractions of one charge, why a cold battery gives less, and the charging and storage habits that keep a lithium cell healthy for years.

Why fingers go cold first, what wind does to a 30-degree morning, and where a pocket warmer earns its place on the course, in the stand and on the lift.
Read the guideIt is two rechargeable hand warmers in one box, sold in ten colors. Carry them apart, one per pocket or one per person, or press them back to back and they become a single warmer heating all the way around. Each unit charges over USB-C and offers three heat levels.
Our figures for one unit are up to 20 hours on Low, 14 on Medium and 8.5 on High. Treat them as the most you will get. A windy, freezing day and lots of switching on and off bring them down, so start your plans from the shorter end.
Use the USB-C cable that comes in the box and any USB charger. Charge indoors at room temperature, and our battery guide explains why a frozen battery should warm up first. The lights on each unit show how much battery is left.
That is what the second warmer is for. Hand one to your partner on the bleachers or to a friend on the chairlift, and each of you sets your own level with your own button. Our page on the UNIHAND gift has more ideas.
Yes. Pack them switched off in your carry-on bag and check your airline's own rules before an international trip. Our battery guide sets out the flying rules for lithium devices, with the sources.
Pick the shell you would like to hold every winter morning, since every color heats the same. Black and Dark Green look quiet, Champagne and Bronze look warm, and Sky Blue is the brightest. Our colors page shows all ten side by side.
