Step-by-step instructions
Important note regarding adapters:
Only USB adapters with a maximum output power of 5V are suitable for charging LIINI®. output power of maximum 5V!
When using fast-charging adapters, it is essential to ensure that the adapter can automatically regulate the corresponding output charging power to 5V/3A. This is usually marked with: 5V/3A OR 9V/2A OR 12V/1.5A . Otherwise the battery may be defective!
It is important to us that you use our products correctly. For this reason, you will find below step-by-step instructions on how to use LIINI® correctly, which can be used with both breast milk and powdered milk. If there is anything special to note, you will find a note under the corresponding steps 🙂
General information:
- The battery must be 100% charged before using the device for the first time !
- The appliance must NEVER be operated without a baby bottle with water / breast milk. Otherwise, the circuit board of the appliance may be damaged due to the enormous heat. In such a case, all guarantee and warranty claims are excluded.
- Both the baby bottle and all LIINI components (seal and heating plate) must always be cleaned thoroughly BEFORE and AFTER use!
- Incorrect use can lead to large temperature differences(actual temperature is lower than the temperature displayed on the bottle warmer)
- LIINI® is not suitable for heating cold water or cold breast milk from the refrigerator. The battery power is too low for this! If you still want to heat breast milk from the fridge, we recommend that you keep the appliance connected to the mains (with the USB charging cable plugged in during the heating process). Please note that LIINI takes longer to heat liquids from the refrigerator than a conventional domestic hot water warmer.
- LIINI® is a gadget for parents on the go – the focus is on uncomplicated warming of the baby bottle, no matter where and when. With our products, we do NOT focus on the speed of heating. Heating too quickly reduces the quality and can even destroy important nutrients!
- The bottle warmer must always be placed on a flat surface (e.g. table) during the warming process to ensure accurate warming
- LIINI® must never be left unattended (e.g. overnight!). We expressly point out that LIINI® is only suitable for short-term warming of baby food, e.g. on the go, on a hike or on vacation under the supervision of an adult.
1. remove the dust cover
The cute bunny ears protect the LIINI® warming area from dirt such as dust and other environmental particles. Before using the bottle warmer, you must therefore remove the dust cover and then clean the warming area or heating plate with damp water. Under no circumstances should you start LIINI® with the ears still attached. Although the bottle warmer has overheating protection, this can destroy the ears or make them unusable.
2. check sealing ring
Before using the bottle warmer, the correct installation of the sealing ring must be checked. The sealing ring prevents liquid from leaking during the heating process. For most baby bottle brands, the sealing ring must be installed as shown in the picture on the left. In this installation form, the sealing lips point upwards (lips visible). However, there are baby bottles where the sealing ring must be installed in the opposite direction. This is particularly the case with the following brands:
- CHU CHU
- Combi
- HiTo
- DoubleHeart
- Lansinoh
- TUTU
3. screw on the adapter
Next, an adapter must be screwed on when using the following baby bottle brands:
- MAM
- NUK
- Tommee Tippee
- All other bottles that have a narrow neck (the Medela adapter must be used here, even if your bottle is not from Medela).
When screwing on the adapter, it is important that it is not tilted and is tightened hand-tight.
For all other brands NOT listed above, the baby bottle can be screwed DIRECTLY to LIINI®.
4. add breast milk / water
For breast milk: Breast milk should be at room temperature when heated and can be poured directly into the LIINI® bottle warmer.
For powdered milk / breast milk substitutes: When using powdered products, the mineral water from the bottle (or boiled tap water) must now be poured into the baby bottle warmer in the desired quantity. The milk powder is not yet added.
After adding the desired bottle content per meal, the baby bottle can be screwed to the adapter and the bottle warmer.
5. start LIINI
By pressing and holding the start button on the underside of the appliance (for approx. 2 seconds), you can now choose between the three temperature levels (37° / 40° / 45°).
A quick tap on the start button displays the battery status.
6. warm breast milk / water
You’ve almost made it! LIINI® now automatically takes care of reaching the previously set temperature. For heating, it is important that the LIINI® is placed on a parallel surface (e.g. table). The baby bottle warmer must never be upside down during warming!
Important: Our bottle warmer has a gentle process to bring the water or breast milk to the desired temperature. This prevents the contents from overheating and losing important nutrients. For this reason, the contents of the baby bottle (breast milk or mineral or tap water) must always be in contact with the hotplate during heating. always have contact with the heating plate. This is the only way to ensure that the temperature displayed corresponds to the actual temperature of the contents.
When LIINI® has reached the desired temperature, beeps the bottle warmer. From this point on the baby bottle is ready for your baby. If you want to wait a little longer before feeding, you can leave the contents in the baby bottle without any problems. The LIINI takes care of maintaining the desired temperature fully automatically.
7. add milk powder
For breast milk: If you are feeding your baby with breast milk, you can now screw the teat onto the baby bottle – that’s it. You have made it!
For powdered milk / breast milk substitutes: If you are feeding your baby with milk substitutes, you can add the milk powder once the desired temperature has been reached. Please mix everything well!

For our reference measurements, we decided on an initial temperature of 25°C because LIINI® is a gadget for on the go. As a rule, bottled mineral water or breast milk, stored in the handbag, is used unrefrigerated (for a short time!) and at approx. 25° to prepare the bottle.
We have verified the temperature several times after heating the pot using different thermometers (digital and analog). The LIINI® bottle warmer has a tolerance of approx. 2°C, whereby the specified temperature has only been undershot to protect the baby , but never exceeded.
If you want to verify the temperature with another thermometer, proceed as follows:
- Heat the milk to the desired temperature (37 ° / 40 ° / 45 °) with the bottle warmer until the beep signal sounds
- Remove the baby bottle from the LIINI® and mix the contents for 5 seconds (circular hand movements)
- Now you can check the temperature in the middle of the contents
No! Breast milk or water straight from the fridge (around 3-5°) is not suitable for heating with LIINI®. The battery power is too low for this. LIINI® was designed for when you are traveling, in a restaurant or visiting friends, for example.
LIINI® is available in the following two versions::
- Little Princess
- Babyboy
