Same Trusted Spectra Performance

The S2 Plus shares the same hospital-grade motor, closed system design, and dual-mode technology as the S1 Plus — in a streamlined, plug-in package that keeps things simple.

Frequently Asked Questions

What's the difference between the S2 Plus and S1 Plus?

The S1 Plus has a built-in rechargeable battery for cord-free pumping, while the S2 Plus uses a plug-in AC adapter. Both share the same hospital-grade motor, closed system, dual pumping modes, night light, and LCD display. The S2 Plus is the right choice if you'll mostly pump near an outlet and want the same performance at a more accessible price.

What's the difference between massage mode and expression mode?

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.

Can I use it as both a single and double pump?

Yes. The S2 Plus supports single and double pumping. You can pump one breast at a time or both simultaneously, depending on your schedule and preferences. Double pumping typically shortens session time.

What does "closed system" mean?

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

What's included in the kit?
  • Spectra S2 Plus electric breast pump unit
  • Spectra Backflow Protectors — includes silicone membrane, uppercase, and lowercase for each backflow protector
  • Spectra Wide Neck Storage Bottles — includes nipple, cap, disc, and lid for each bottle
  • Spectra 12-Volt AC Power Adapter

Note: Included parts may vary by kit. Check the "Included" section above the Add to Cart button for the exact configuration.

How quiet is the S2 Plus?

The S2 Plus uses the same quiet motor as the S1 Plus. It's designed for discreet operation, making it comfortable to use at work, during naps, or in shared spaces without drawing attention.

Tips for getting the most from your S2 Plus
  • Start sessions on a gentle setting, then increase gradually to a comfortable level.
  • Keep spare valves and membranes on hand. Replacing wear parts regularly helps maintain suction performance.
  • Use the built-in timer to track session length and build a consistent routine.
  • If you need to pump away from an outlet, consider a portable battery pack that outputs 12V DC as a workaround.
