Youha The Cube Portable Warmer

The Youha The Cube Portable Warmer is a compact, battery-friendly bottle warmer built for feeding away from home. It gently heats breastmilk or formula to a temperature you set, so you can get a feed ready in the car, at a friend's place or on a day out without hunting for a plug point or a kettle. If you've been juggling cold bottles and impatient babies while out and about, this is the small, packable device that takes some of that scramble out of the day.

At 85 x 85 x 71 mm and around 300 g, The Cube is genuinely pocket- or nappy-bag-sized, and it warms 120 ml in roughly 2–4 minutes. An LCD display shows the temperature reading and makes it easy to see what setting you're on, with adjustable settings across a 37–50°C range so you can warm milk or food to the point you prefer.

Set the temperature you want

Rather than a single fixed setting, The Cube lets you choose across a 37–50°C range and shows the reading on the LCD screen. As with any warmer, the display reflects the device's own reading rather than the exact temperature at the centre of the feed, so it's still worth giving the bottle a gentle swirl and testing a few drops before you offer it to your baby.

Made to travel

The Cube carries an IPX6 water-resistance rating and a build meant to stand up to everyday use, which makes it suited to bags, prams and the general knocks of life with a baby. It's compatible with over 20 major baby bottle brands, though the adapters that make those connections are sold separately, so it's worth checking you have the right one for your bottles before a trip.

Everyday safety

An auto shut-off feature switches the unit off to help prevent overheating when there's no liquid present, which is a useful bit of reassurance for a device that tends to live in a bag and get used on the move.

Best For

The Youha The Cube Portable Warmer is a great option for parents who:

• Feed away from home often and want to warm a bottle without a plug point or kettle nearby
• Prefer to choose their own warming temperature and see a reading on a display
• Want something small and light enough to keep in a nappy bag or pram

It may not be the best fit if you:

• Only feed at home and would rather use a mains-powered warmer with a larger capacity
• Warm large volumes at once, as heating times are quoted for 120 ml

Pandylane Pro Tip: The adapters that connect The Cube to different bottle brands are sold separately, so check which adapter suits your bottles and pack it before you head out — it's the easy thing to forget.

Warming is optional: milk doesn't have to be warm to be served, provided it's otherwise stored and handled correctly. Always follow the device instructions and your healthcare provider's guidance, and check the temperature of the feed yourself before giving it to your baby.
