The SilkMum S1 wearable hands-free breast pump delivers discreet, comfortable, and efficient pumping wherever life takes you. Ergonomically engineered with a 130° ultra-wide angle for better fit and comfort, S1 simulates a baby’s natural suckling with four modes (Massage, Pumping, Enhanced, Blending) and 9 adjustable intensity levels. The integrated 1200mAh rechargeable battery supports approximately 3-4 pumping sessions (each lasting around 30 minutes) after a 2– 3 hour USB-C charge. A clear LED touch display shows mode, level, and battery status while the device auto shuts off after 20 minutes for safety. With a 120ml collection bottle, BPA-free silicone shield, and simple, few-part assembly, the SilkMum S1 is quiet (<45 dB), portable (~240 g), and easy to clean, making it perfect for on-the-go, at-work, or at-home use.
