Warm milk stays warm wherever the feed happens. This slim USB sleeve runs on a power bank, car port or wall charger and gives you three heat levels at the press of a button.
Keeps milk warm on the go, powered by any USB source
- cold milk during night feeds
- no access to warm water when out
- bulky warmers that are hard to carry
Warm milk for every feed, wherever you are
Cold bottles at 2am and no warm water on a stroller walk are a daily struggle. Now your milk stays warm on the move, powered by a USB source you already carry.
Pick the warmth your feed needs

Three heat levels, one button
Press to cycle 70% output (55 degrees), 100% (65 degrees) and 40% (45 degrees). The LED ring changes color so you know the level at a glance, even in a dark nursery.
Power from any USB source
The 5V 2A input works with a power bank, a car USB port or a wall charger. No outlet hunt, no bulky base to pack.

Four layers that hold heat
A four-layer insulated wall with a heating layer sits inside a grey PU leather exterior. A carry loop with a silver snap lets you hang it from a stroller or bag.

From cold bottle to calm feed

The 2am bottle
The bottle is cold from the fridge. The baby is fussing and you are too tired to think. Warm water is a walk away, and the crying will not wait.

The fix you can carry
A compact USB sleeve gives you warm milk without the bulk of a plug-in warmer. It fits the bag you already pack and plugs into the power bank already in it.

Warm feeds, anywhere
Stroller walks and car trips stop being a countdown. The milk is warm when the baby is hungry, and you test it on your wrist before you feed.
Keep the sleeve looking new
- Wipe clean
Soft damp cloth on the exterior.
- Keep it dry
Do not soak the sleeve or USB port.
- Unplug after use
Disconnect once the milk is warm.
- Check the cable
Look for wear on the cable regularly.

Questions and answers
Yes. It takes USB DC 5V 2A, so a power bank, a car USB port or a wall charger will run it. A weak 1A port may heat slowly.
It is a warming sleeve. It holds milk at a set warmth with three levels: 45, 55 and 65 degrees. It does not sterilize milk.
Swirl the bottle and put a few drops on your inner wrist. It should feel comfortably warm, not hot. Always do this before every feed.
Wipe the outside with a soft damp cloth and dry it. Keep the sleeve and the USB connector away from soaking water.
You pay once for a sleeve that works at home, in the car and on walks, so you skip carrying thermoses of hot water or a second device.
The bottle warmer sleeve and a USB charging cable. A power bank or charger is not included.
