Once fully charged, always remember to disconnect the power cable from the outlet. Doing so helps preserve the battery's good functionality over time.
CHECKING THE BATTERY LEVEL
By briefly pressing (1 second) and only once the power button, 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 battery of the Warm’n’Go bottle warmer behaves differently from traditional rechargeable batteries, such as those in cell phones. Its battery is described 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 “OL”
For example, when the battery is at 90%, the display will show 80, and when it’s at 70%, the display will show 60.
USING THE DEVICE WITH A CHARGE LEVEL BELOW 20
You can use Warm’n’Go even with a charge level of 20, but it’s recommended to connect it to the charger to avoid it shutting off before finishing the heating process.
LOW BATTERY WARNING AND AUTOMATIC SHUTDOWN
• During use, if the battery level reaches 20, an audible signal will remind you to recharge it.
• When the battery level drops below 20, the display will show “OL” and the product will shut down automatically.
• When the bottle content is less than 20 ml or dry, the product will shut off automatically to protect the battery from possible damage.
PRECAUTIONS
• The product is shipped with a factory pre-charge that is not 100%. If used before being fully charged, the battery’s memory will not reset, preventing it from reaching 100% during subsequent charges.
• Using a charger with specifications different from those recommended can damage the battery and negatively impact the product’s performance, as well as void the warranty.

❗ The heating time varies depending on the amount and initial temperature of the liquid, the ambient temperature, the type of bottle, and the set heating temperature.
▶️ Warm’n’Go will notify you with a beep when it has reached the temperature you set.
▶️ To ensure the liquid heats evenly, stir the liquid as described in the next section.
The indicated performance may vary by ±10%.
▶ PRACTICAL EXAMPLES
The time required 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 the summer or in the mountains during winter?
• If you want to heat 120 ml of liquid to 37°C (the ideal body temperature for infant milk) starting from room temperature (for instance, you're at the beach on a summer day at 27°C), the temperature difference is only 10°C, and Warm’n’Go will need just 4 minutes.
• However, if it's winter and you're outdoors (for example, at 10°C) and you want to heat a double quantity (e.g., 240 ml), the bottle warmer will need more time to bring the liquid to the same temperature.
The device is optimized to heat up to 240 ml, so for larger quantities, longer heating times will be necessary.

TIPS FOR ACHIEVING A CONSISTENT TEMPERATURE
✅ WHAT TO DO
During heating, gently stir the bottle's contents by moving it gently to allow the liquid to mix and for the sensor to display the actual temperature of the liquid. It's normal for the indicator to show a lower temperature when you stir.
❌ WHAT NOT TO DO
Do not rely on the temperature displayed by the bottle warmer as the real temperature if you haven't stirred the liquid during the heating process, as the heat won't be evenly distributed.
Do not turn the bottle warmer upside down during the heating process.
▶ MORE INFORMATION
Milk in contact with the heating plate reaches the desired temperature before the milk in the upper layer, which is farther from the heating plate.
To ensure even heating, gently stir the contents during the heating process.
If the liquid is not stirred during heating, some areas will remain cold, especially if the liquid is over 240 ml or if the starting temperature was very low.
During use:
• Do not turn the bottle warmer upside down, which would leave the heating plate dry.
• Do not remove the bottle from the warmer during heating.
The temperature sensor is located on the heating plate. Once the desired temperature is reached, it stops the heating process.

HOW LONG DOES IT KEEP THE HEAT?
❗You can use Warm’n’Go to maintain the liquid at the desired temperature for several hours, such as keeping hot water ready for nighttime feedings.
The performance indicated in the table may vary by ±10%.
▶ MORE INFORMATION
• The maximum operating time for maintaining heat is approximately 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 water warm throughout the night, we recommend keeping the bottle warmer connected to the power source.
• For breast milk, it is recommended not to exceed 30 minutes of heat maintenance. Always consult a neonatal nutrition specialist for advice on proper nutrition and appropriate temperatures.
