Put the cold boiled water into the milk bottle, put the milk bottle into the milk warmer, and then hand it over to the automatic constant temperature milk warmer. Don't worry about flushing milk in the middle of the night. When it is heated to 42 ℃, the thermostatic lamp will be on and kept at this temperature. Precise temperature control: the real-time monitoring spring temperature controller is more suitable for temperature measurement, and the bottom temperature measurement is more accurate ± 42 ° C constant temperature warm milk. Note： Please make sure that the bottom of the feeding bottle is closely attached to the temperature control head with spring on the base, otherwise the temperature controller will not be able to measure the temperature, and the temperature will be too high. Please make sure that the insulation is appropriate before feeding. The Velcro is easy to take and place: The Velcro can be adjusted freely to fit the milk bottle better and adapt to different milk bottle diameters and bottle types. Multilayer thermal insulation materials: multiple thermal insulation materials are used for more lasting insulation, so that the milk warmer can last longer, save electricity, and be more convenient. Power supply/power supply: from the USB port.
