The most powerful bottle warmer on the market

With 15,000 mAh, the LIINI bottle warmer 4.0 is the most powerful mobile bottle warmer on the market. In comparison, the LIINI 3.0 has 10,000 mAh – strong, but the 4.0 delivers noticeably more power. And that’s exactly what makes the difference for you in everyday life.

More battery means: several bottles in a row, a whole day on the road without recharging and no stress with sockets, thermos flasks or planning. When your baby is hungry, you don’t want to improvise – you want it to just work. The LIINI 4.0 delivers constant power and heats reliably, even when things need to be done quickly.

In short: less waiting time, less stress, more freedom – so you can concentrate on your baby instead of the next meal.

Swiss quality - for you and your baby.

On the electronics side, the power and start architecture has been specifically modernized – including a new power controller (PMIC) and a cleaner separation of battery, control and power section. This ensures a controlled, stable voltage build-up and greater overall robustness – especially when the battery level is low or the conditions are more demanding.

IP66 protection against dust & water

The LIINI bottle warmer 4.0 is consistently designed for everyday use with babies. While the LIINI 3.0 was only protected against light splashes with IPX4, the 4.0 offers significantly higher protection against water and dust with IP66. Rain, wet hands or a mishap in the kitchen are no longer a problem.

In addition, even the PCB (the electronics inside) of the LIINI 4.0 is specially coated. This means that the bottle warmer is protected even where you can’t see it. Moisture, condensation or steam are much less likely to damage the electronics – for greater reliability and a longer service life.

For you, this means quite simply: less worry, more confidence. You can use the LIINI 4.0 in everyday life, on the go or when traveling without having to be constantly careful. It is made for situations in which not everything goes perfectly – just like real life with a baby.

And best of all: with a whopping 15,000 mAh, LIINI® has the most powerful battery in its class – more than any other bottle warmer. Perfect for the next visit to friends or a well-deserved vacation in the sun.

Towing? Nope.

Lugging a thermos? Nope, you don’t have to anymore with LIINI®. The bottle warmer combines everything in one small device and is just as big as the palm of your hand and as heavy (or light) as your smartphone. Of course, the device also has an integrated thermometer.

How to find the perfect ring size

Do you already have another ring at home?

Yes - measure ring

If you already have a good fitting ring, you can use that to determine the size.

Step 1: Prepare material

  • An existing ring that fits well
  • A ruler or tape measure
  • A pen and a sheet of paper

Step 2: Measure the existing ring

Lay the existing ring flat on a flat surface. Make sure that it does not deform or twist. Use the ruler or tape measure to measure the inside diameter of the ring. This is the distance from one inner edge to the opposite inner edge of the ring. Note the measurement in millimeters.

Step 3: Compare with our size chart

Now compare the measurement you noted with our size scale and choose the appropriate ring size.

No - Measure finger

If you don’t have a matching ring at home, you can easily determine your size with the following procedure.

Step 1: Prepare material

  • A thin strip of paper or a piece of string
  • A pen
  • One pair of scissors
  • A ruler or tape measure

Step 2: Measure the circumference of the finger

Wrap the thin strip of paper or string around the finger you want to wear the ring on. Make sure the strip fits snugly, but not too tight or too loose. Use a pencil to mark the place where the strip or string overlaps.

Step 3: Check the size

To make sure that the determined ring size is correct, you can wrap the thin paper strip or string around your finger again and place the ring on it. Check that it fits comfortably and is not too loose or too tight. Repeat this step if necessary to find the optimal size.

Tip: If you want more accurate measurements, you can repeat the process several times and take the average of the measurements.

Step 4: Compare with our size chart

Now compare the measurement you noted with our size scale and choose the appropriate ring size.
