This Elvie Pump Single is a smart, thin, wearable electric breast pump that fits discreetly in a bra and holds up to 150 ml of milk, ideal for on-the-go feeding and hands-free expression. This is controlled via the Elvie app and uses SmartRhythm™ with four suction modes and seven intensity levels to optimize milk production, protect sensitive nipples, or quickly express full breasts. This compact, quiet, all-in-one pump has no tubes or external parts and expresses directly into 150 ml reusable, freezer-safe bottles that clean easily—only five dishwasher-safe parts made from BPA-free plastic, Tritan and food-grade silicone. This charges in 2 hours for up to 2.5 hours of use (about 5–6 sessions) and arrives with two bottles, two breastshield sizes (24 mm and 28 mm), valves, lids, bra adjusters, USB cable and carrying bag; two units can pair to create a double pumping setup.
