Spectra Baby S1 Plus Premier Portable Rechargeable Breast Pump with Tote Bag and Premium Accessory Kit – 24mm

Product description

Which flange size should I use?

Flange fit drives comfort and how much milk you express. The box includes 24mm and 28mm flanges, with 16mm to 32mm sold separately. To size correctly, measure your nipple’s diameter and add 2-3mm. A wrong-size flange can reduce comfort or output.

The suction feels weaker than it used to — is the pump failing?

Almost always, no. Lost suction usually comes from a duckbill valve or backflow membrane that’s slipped, loose, or worn. Seat the duckbill fully, keep parts dry so the seal holds, and reassemble correctly. If it persists, replace these parts.

The rhythm feels different from what I expected — is something wrong?

The S1/S2 Plus use our Natural Nursing Technology, which simulates how a baby suckles at the breast. Use massage mode first to bring on your letdown, then expression mode to draw milk — together they recreate a baby’s natural feeding rhythm.

How is the S1 Plus different from the S2 Plus?

They’re the same pump in every way but one. Both deliver identical suction, modes, and settings; the S1 Plus adds a rechargeable battery for portable use, while the S2 Plus runs on a cord. If mobility matters to you, the S1 Plus is the one to choose.

How do I charge it, and can I pump while it’s charging?

Yes — you can pump while it’s plugged into the AC adapter, and the battery charges at the same time so it’s ready to go cordless when you are. Charge it about four hours, and avoid leaving it on longer, which can shorten battery life over time.
