What is spectra s1?
The Spectra S1 (often called the S1 Plus) is a hospital-strength, electric breast pump from Spectra Baby USA, featuring a closed system design, customizable modes, and a rechargeable battery—ideal for moms looking for powerful yet portable pumping solutions.
Key Features

- Hospital-level suction: Delivers strong vacuum power (up to 270 mmHg), suitable for single or double pumping
- Dual-phase settings: Massage mode (~70 cycles/min) to stimulate let-down, and expression mode (~38–54 CPM), both with adjustable suction levels
- Rechargeable & cordless: Built-in battery provides about 3 hours of pumping per charge, freeing you from always needing an outlet
- Quiet operation with nightlight: Rated around 45–55 dB, plus a built-in nightlight and timer display—a plus for discreet use at night
- Portable & user-friendly: Weighs about 3 lb, with a convenient handle and fully digital controls
- Flange options: Comes with 24 mm and 28 mm shields; parts are BPA-free and easily replaceable
