Portable bottle warmer plus adapters. In box without charging cord. Our portable bottle warmer is designed to provide the ultimate feeding experience for your baby whether you're at home, running errands, or on a remote hike, making feeding your little one a breeze. The sleek, stainless steel, leak-proof design means that parents do not have to transfer milk from the warmer to the bottle while also allowing parents to pick whichever bottle is their favorite. Equipped with advanced smart sensor technology, it ensures that your baby's bottle is always warmed to the ideal temperature, without any risk of overheating or nutritional deterioration. The gentle warmth of the liquid can help to reduce colic symptoms by providing a soothing and calming sensation, relaxing the digestive system, and promoting the production of digestive enzymes. You can be confident that you and your baby will enjoy a comfortable and stress-free feeding experience every time. The warmer set includes four of our most popular adapters. These adapters are compatible with Comotomo, MAM, Narrow neck Dr. Brown, and Tommee Tippee bottles, and each of them accommodates multiple bottle brands.
