Usage Features:
The Bottle Warmer features a simple operation process. To use, purified water or milk is poured into a baby bottle, and the warmer is screwed upside down onto the bottle. If the bottle doesn't fit directly, adapters are available for various bottle brands and neck sizes (39mm narrow neck, 53mm wide neck, 56mm ultra-wide neck).
The device is turned on by long-pressing the power button for 3 seconds. The desired temperature (37°C, 40°C, 45°C, 50°C) is selected by lightly pressing the power button. The liquid will then be heated and maintained at the chosen temperature until the warmer is removed. The heating time is approximately 4 minutes, and a fully charged battery allows for about 10 heating cycles.
The Bottle Warmer also offers a reservation function, allowing users to preset a warming time (30, 60, 90, 120, 150, or 180 minutes). This function can extend battery life and prevent overheating of milk during long heat preservation processes. The temperature unit can be switched between Fahrenheit (°F) and Celsius (°C) by pressing the reservation button for 3 seconds in the power-off state, then pressing the power button for 3 seconds to toggle between units.
The device includes an LED display that shows the current temperature. It also provides battery status LEDs (1, 2, or 3 LEDs indicating 0-20%, 21-60%, and 60-90% charge respectively) and error warnings:
- "Lo" indicates low battery (<20%), prompting a recharge.
- "Hi" indicates a high temperature (>55°C).
- "E3" indicates dry boiling, requiring the user to add water or turn off the device to cool down.
The Bottle Warmer can maintain water warmth at 40°C for up to 12 hours on a full charge. It is important to note that actual heating and heat preservation times may vary based on ambient temperature, bottle material, initial liquid temperature, and water volume.
Maintenance Features:
Regular cleaning and occasional descaling are essential for the Bottle Warmer's optimal performance and longevity.
- Cleaning: After each use, the Bottle Warmer should be cleaned and dried. It must be allowed to cool completely before cleaning. The device should be switched off and unplugged from the USB charger before cleaning. A soft dry cloth is recommended for cleaning the exterior. Avoid excessive pressure on the display and buttons. The sealing ring should not be damaged during cleaning. The Bottle Warmer must not be submerged in water or rinsed with water to prevent electrical circuit damage. Abrasive objects, aggressive cleaning agents, alcohol, or other chemical solutions should not be used. The device is not dishwasher-safe.
- Descaling: If tap water is used, limescale can build up, affecting performance. Descaling is recommended every 1-3 weeks, depending on water hardness and frequency of use. The descaling procedure involves mixing white vinegar with an equal amount of 50°C hot water, pouring the mixture into the base, and letting it sit for about 10 minutes until the limescale dissolves. Afterward, the base should be emptied and rinsed thoroughly with clean water, then dried. Citric acid can also be used for descaling. Good ventilation is advised when descaling with vinegar.
- Storage & Transport: Before long-term storage, the Bottle Warmer should be cleaned and allowed to cool completely. It should always be stored with a closed dust cover in a dust-free place, away from direct sunlight, humidity, and extreme temperatures. Wet or damp parts should not be stored to prevent mold or rust. The device should be stored out of reach of small children. The battery should be recharged every 3 months, even if not used. The USB cable should be coiled loosely, not wrapped around the device. During transport, the device should be protected against vibrations and shocks.
Safety Instructions:
- Always read and follow the user manual carefully to prevent damage or harm.
- The device is intended for household use only, not commercial or industrial use.
- Use only indoors.
- Handle with care; avoid shocks, impacts, or falls.
- Place on a stable, heat-resistant surface, not on carpet or plastic.
- Ensure all parts are correctly assembled.
- Use only the manufacturer-recommended accessories.
- Do not insert objects or fingers into any openings.
- Do not apply excessive force to buttons or the display.
- Do not leave the switched-on Bottle Warmer unattended, especially near children.
- Avoid strong magnetic fields and dusty environments.
- If visibly damaged or malfunctioning, discontinue use.
- Water Safety: The device is not waterproof. Never use with wet hands, submerge in water, or rinse with water. If it falls into water while charging, unplug the USB charger immediately before retrieving the device. Ensure the device is on a dry surface.
- Battery Safety: Do not place near fire or direct sunlight. Do not charge below 5°C or above 40°C. Discontinue charging if the battery does not charge within the specified time or if it emits substances, overheats, or leaks. Charge only with a 5V/3A USB charger. Do not charge near flammable materials. Do not puncture, modify, disassemble, or replace the battery. Do not touch leaking materials or inhale fumes. Do not throw the battery into fire. Avoid short-circuiting the battery terminals.
- Operation Cautions: Do not touch stainless steel parts during heating to avoid burns. Always use sterilized bottles. Wash hands thoroughly before contact with sterilized parts. Heating time should not be too long; heat retention for breast milk should not exceed half an hour to prevent spoilage. Always check milk temperature before feeding.
- Unpacking Safety: Keep plastic bags and foils away from babies and children to prevent suffocation. Keep cables longer than 18 cm (7 inches) away from babies and young children to prevent strangulation.
