Loved by moms and lactation consultants worldwide, the Spectra S1 Plus Electric Breast Pump is designed to bring confidence and comfort to every moment of the breastfeeding journey. The Spectra S1 Plus is portable and quickly rechargeable for active moms, but also quiet and discreet for a soothing pumping experience. The added night light allows you to easily pump at any hour. This breast pump conveniently weighs only 2.9lbs. With a maximum suction strength of 270mmhg and the ability to be used as a single or double pump, the Spectra S1 Plus will be a great asset for your breastfeeding journey. The S1 Plus’s completely flexible, touch button with the S1 Plus pump’s digital controls allow you to set the pumping program to the speed and rhythm most effective for your body. The suction is adjustable in both let-down and expression mode. This quiet pump also includes a timer. With the quietest motor available, the S1 Plus, in the “massage mode,” simulates the natural suckling of baby. We thought hard about things like “adjustable suction levels” because it provides a more natural flow of milk.
