The new Medela Swing Maxi is a compact, easy-to-use double electric breast pump designed to fit seamlessly into your lifestyle and express more milk in less time, whenever and wherever you are. With a built-in rechargeable battery that lasts for up to six pumping sessions when fully charged and a cutting-edge USB type C adaptor for quick charging, you’ll never be without power. Swing Maxi™ also offers intuitive, and hassle-free pumping with Bluetooth technology that lets you connect to the Medela Family app for pump session tracking, virtual milk storage, and nine pre-programmed settings that you can choose and control with four easy-to-use buttons. With fewer parts cleaning your pump is a breeze. Medela's 2-Phase Expression® technology mimics this natural sucking rhythm – fast to stimulate milk flow, then slower to provide optimal milk flow. More comfortable pumping with the PersonalFit Flex™ breast shield. Includes two sizes of breast shields in 21 mm and 24 mm sizes with 105-degree opening angle, soft rim, and oval shape that puts 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.
