▶️ The number displayed on the screen (E) corresponds to the current charge level (100, 80, 60, 40, 20, “OL” = 0%).

▶ ADDITIONAL INFORMATION

CABLE AND CHARGER
The battery is charged via the USB-C cable included in your Warm70 package. The charger (B) must have an output power of 5V and 2A (10 Watts). You can use chargers you already have at home, even a phone charger might be suitable, but check the printed specifications before use because chargers have different power outputs and not all are suitable. The OUTPUT 5V 2A is the correct one.
Using the correct cable and charger ensures proper and safe device operation, as well as prolonging battery life. Chargers with different specifications may damage the battery and extend charging times.

USING A POWER BANK
If you are away from home and want to charge the bottle warmer with a portable battery (power bank), use one with at least 10,000mAh capacity.

CHARGING TIMES
  • The full charging time varies between 4 and 6 hours, depending on the initial battery level and the type of charger used.
  • • During the charging process, the display (E) will show the digital lines "---" and "100" when fully charged.
  • • The device can be used with a minimum charge level of 20.
    Once fully charged, always remember to disconnect the power cable from the outlet. Doing so preserves the battery’s functionality over time.

  • CHECKING THE BATTERY LEVEL
    Briefly press (1 second) the power button once; the display (E) will show the current battery charge level: 100, 80, 60, 40, and 20.

    HOW TO READ THE CHARGE LEVEL ON THE DISPLAY
    The Warm70 bottle warmer battery behaves differently from traditional rechargeable batteries, such as those in mobile phones. It is defined as a "single cell" battery, and the charge levels follow an irregular progression:
    Full charge 100%: Level 100
    From 95% to 80% charge: the display shows Level 80
    From 79% to 60% charge: the display shows Level 60
    From 59% to 40% charge: the display shows Level 40
    From 39% to 20% charge: the display shows Level 20
    Below 20% charge: the display shows the code OL
    For example, when the battery level is at 90%, the display will show 80; when it is at 70%, the display will show 60.

    USING THE DEVICE WITH A CHARGE LEVEL BELOW 20
    You can use Warm70 even with a charge level of 20, but it is recommended to connect it to the charger to avoid it shutting off before completing the heating.

    LOW BATTERY WARNING AND AUTOMATIC SHUTDOWN
  • • During use, if the battery level reaches 20, an acoustic signal will remind you to recharge it.
  • • When the battery level falls below 20, the display will show "OL" and the product will automatically shut off.
  • • When the bottle content is below 20 ml or dry, the product will automatically shut off to protect the battery from damage.

  • PRECAUTIONS
  • • The product is shipped with a factory pre-charge that is not 100%. If used before fully charging, the battery memory will not reset, preventing the level 100 from being reached during subsequent charges.
  • • Using a charger with different specifications than recommended can damage the battery and negatively affect product performance, as well as void the warranty.
  • A USB-C cable included
    B Charger. Read the "output" label before use

    HOW MANY BOTTLES CAN YOU WARM WITH A FULL CHARGE (LEVEL 100)?

    Battery life varies depending on the quantity and initial temperature of the liquid, as well as the desired target temperature.

    ❗ Ambient temperature and bottle type can also affect
    the warming time and therefore the battery life.


    The performance indicated in the table may be subject to a variability of ±10%.

    Frequently Asked Questions

    ▶ ADDITIONAL INFORMATION

    The battery life varies depending on the amount of liquid heated, the initial temperature, and the temperature you want to reach. Starting from a full charge level of 100, to heat 120 ml of milk stored at room temperature to 37°C:
  • • At the end of the first heating, the level drops to 80.
  • • After the second heating, the level drops to 60.
  • • After the third and fourth heating, it still shows 60.
  • • After the fifth, sixth, and seventh heating, it shows 40.
  • • The eighth heating will start from 20. In this case, if you heat a quantity of milk greater than 120 ml, it is advisable to connect the power adapter because the bottle warmer could turn off before finishing the heating.

    The progression can drop faster depending on the type of use.

    The indicated performance may be subject to a variability of ±10%.

    ▶ PRACTICAL EXAMPLES

    The time needed to bring all the water or milk to the desired temperature depends on various factors. Let's consider an extreme example: are you at the beach in summer or in the mountains in winter?
    • If you intend to warm up 120 ml of liquid to 37°C (ideal body temperature for newborn milk) starting from room temperature (for example, you are on the beach on a summer day at 27°C), the temperature difference is only 10°C and Warm70 will need just 4 minutes.
    • However, if it's winter and you are outdoors (for example, at 10°C) and want to warm a double quantity (for example, 240 ml), then the bottle warmer will need more time to bring the liquid to the same temperature.
    The device is optimized to warm up to 240 ml; consequently, for larger quantities, longer heating times will be necessary.

    Frequently Asked Questions


    WHAT TO DO
    During heating, stir the contents of the bottle by gently moving it to allow the contents to mix and for the sensor to indicate the actual temperature of the liquid. It is normal for the indicator to show a lower temperature when stirring.

    ❌ WHAT NOT TO DO
    Do not consider the temperature indicated by the warmer as the actual temperature if you have never stirred the liquid during the heating period, because the heat will not be distributed evenly.
    Do not invert the warmer during the heating process.

    ▶ ADDITIONAL INFORMATION

    The milk in contact with the plate reaches the desired temperature before the milk in the upper layer, farther from the heating plate.
    To heat evenly, therefore, gently stir the contents during the heating period.
    If the liquid is never stirred during heating, some spots will remain cold, especially if the liquid is more than 240 ml and if the starting temperature was very low.

    During use:
    • Do not invert the bottle warmer, leaving the heating plate dry
    • Do not remove the bottle from the bottle warmer

    The temperature sensor is located on the heating plate; once it detects the target temperature, it stops heating.

    HOW LONG DOES IT KEEP THE HEAT?

    ❗You can use Warm70 to keep the liquid at temperature for several hours, for example warm water for night feedings.


    The performance indicated in the table may be subject to a variability of ±10%.

    ▶ ADDITIONAL INFORMATION

    • The longest operating time for heat maintenance is about 8 hours for 120 ml of liquid kept at 37°C. This heat maintenance time is based on a full battery charge.
    • If you want to keep the water warm overnight, we recommend keeping the bottle warmer connected to the power adapter.
    • For breast milk, it is recommended not to exceed 30 minutes of heat maintenance. Always consult a neonatal nutrition specialist for advice on nutrition and appropriate temperatures.

    Frequently Asked Questions


    Special infant formulae are designed to meet specific needs, such as intolerances, allergies, colic, constipation, gastroesophageal reflux, prematurity, or low birth weight. These products are classified as foods for special medical purposes and should only be used under the pediatrician's prescription, who evaluates the child's medical history and clinical conditions.

    If special formula is required for feeding your baby, it is important to know that its composition has a higher fat percentage than regular infant formula, and this requires appropriate temperatures and heating times that may differ from the standard guidelines.

    ▶ HOW TO USE THE PORTABLE BOTTLE WARMER TO HEAT SPECIAL MILKS


    • Set the heating temperature between 40°C and 45°C.
    • Stir the milk well during the first few minutes by moving the bottle (even if the bottle warmer is the model with mixing spiral).
    • Check the heating from time to time to reach around 37°C, suitable for consumption.

    If the final temperature is not satisfactory, a second heating may be useful as the milk is already partially warm.

    This system allows you to optimally heat the special milk without compromising its medical properties.

    It is recommended to follow the described procedure especially with milk that has already been reconstituted at home or with liquid milk.
