The new Swing Maxi is a portable, compact, and easy-to-use double electric breast pump made to fit seamlessly into your lifestyle. Mimic baby’s natural feeding rhythm with our 2-Phase Expression® technology. During feeding, babies start by using short, fast sucks to stimulate the Milk Ejection Reflex. Once milk begins to flow, babies change to a slower, individual rhythm to actually feed. Get a comfortable fit with the Personal Fit Flex™ breast shield. The 105-degree opening angle, soft rim, and oval shape put less pressure on your milk ducts than traditional breast shields for a more effective and comfortable pumping experience. More comfort for you, with up to 11. 8% more milk for your baby – clinically proven. Includes breast shields in 21 mm and 24 mm sizes. Pump wherever you are, even if no power outlet is available. With the cutting-edge available USB type C connector, the built-in rechargeable battery lasts for up to six pumping sessions when fully charged. Integrated Bluetooth technology lets you connect with the Medela Family app for pump session tracking, virtual milk storage, and more. Swing Maxi™ has an intuitive, hassle-free design with nine pre-programmed settings that you can choose and control and four easy-to-use buttons. Fewer parts make cleaning your pump a breeze.
