Hospital Strength, Wherever You Go

Massage mode uses a faster, lighter cycle that mimics the initial suckling rhythm to stimulate letdown. Once milk begins to flow, switch to expression mode for slower, deeper suction that maximizes milk output. You can adjust vacuum strength and cycle speed independently in each mode.

Battery life varies based on suction settings, but a fully charged S1 Plus typically supports multiple pumping sessions before needing to recharge. The included AC adapter lets you pump plugged in while the battery charges, so you're never without power.

The S1 Plus comes with 24mm and 28mm flanges. Correct flange fit is essential for comfort and efficient expression. If neither size feels right, Spectra offers additional sizes separately. A lactation consultant can help determine your ideal flange size.

A closed system uses a backflow protector that creates a barrier between the expressed milk and the pump's tubing and motor. This prevents milk and moisture from entering the tubing, making the pump more hygienic and easier to clean. It also means the pump can potentially be shared between users with new accessory kits.
