Portable Baby Electric Water Heator

Non. You can keep your bottles, because the device heats the liquid. Once at temperature, all you have to do is pour it into your bottle and baby just has to taste it.

Yes. Our bottle warmer heats all liquids. The borosilicate glass container allows easy cleaning for perfect hygiene.

As recommended by powdered milk manufacturers, it is best to heat the water before mixing. The mixture will be made directly in the bottle.

The maximum heating temperature is 55°C, which avoids the risk of burns.

GOOD TO KNOW: For babies up to 3-4 months, some pediatricians and milk powder manufacturers will recommend using water that has been previously heated to 70°C to eliminate any germs.

This is particularly recommended for premature babies or if you are unsure of the water quality in your area. If this is your case here are 2 solutions:

1. Take water with you in a clean bottle that has been heated to 70°C. You can use this water for 24 hours

2. Use bottled water suitable for newborns. Again, it can be used up to 24 hours after opening.

The heating time differs depending on the volume to be heated.  3-4min for a 210ml bottle. Max: ∼8min for 300ml.

The borosilicate glass container unscrews and can be cleaned in the dishwasher. Use a damp cloth to clean the base.
For sterilization, simply fill it with boiling water for about 10 min.

Recharging is done using the supplied USB cable, once charged the bottle warmer has an autonomy of about 6 bottles of 300ml.

NB: The energy required to heat water is greater than that required to light an LED bulb. The charger must produce at least 5V and 2A (10W). A smartphone charger is sufficient.

99.9% of people make at least 1 old phone charger at home. For the sake of ecology, we think it is unnecessary to provide a new one. The charger is therefore not included.

We recommend cleaning and sterilizing the bottle warmer before first use.

6. To turn off the device, press the ON/OFF button for 3 seconds.

A problem with your bottle warmer?
Do not worry, most often it is easy to solve it.

Problem: The battery does not fully charge?
Solution : It's probably the USB charger you're using that's not powerful enough. The charger must produce at least 5V and 2A(10W), a smartphone charger is sufficient. (See section "How to recharge it".

Please use only the cable provided.

Problem: Can't use the bottle warmer?
Solution : Follow the instructions in the "instructions for use" section.

Problem: The bottle warmer is not waterproof.
Solution : We recommend filling the bottle warmer only when you need it. If liquid escapes, check that the glass container and cap are properly screwed. Also check that the two gaskets placed above and below the glass container are properly positioned.
