S1 Plus Electric Breast Pump
1
Overview
Description
Many moms love this pump for its exceptional performance, allowing for more productive pumping sessions that fully empty the breast—which can be a game-changer. Also, it’s quiet. The motor operates at 45 decibels, which is basically the hush of a library.
It offers adjustable suction levels for a more natural flow of milk, including the popular massage mode that simulates the natural suckling of a baby. More key features: back-flow protection protects your breast milk from harmful bacteria (it’s a closed-system pump), a night light allows you to pump at any hour, it remembers your most recent settings and it has an auto-shutoff feature.
The biggest difference between this model and the Spectra S2 Plus Electric Breast Pump? This one has a rechargeable battery that lasts up to three hours—so you don’t always have to be plugged in. It’s .5 lbs heavier, but the convenience and portability could be worth it.
What’s Included:
- 1 S1 Plus Electric Breast Pump
- 2 Breast Flanges (24mm)
- 2 Breast Flanges (28mm)
- 2 Wide Neck Storage Bottles (5.4oz) (Includes nipple, cap, disc and cover for each bottle)
- 2 Backflow Protectors (Includes silicone membrane, uppercase, and lowercase for each Backflow Protector)
- 2 Tubing
- 2 Duckbill Valves
- 1 AC Power Adapter/Charger (12V)
What we about it
A pump that's portable, rechargeable and extra quiet.

Q&A
Have a question? Ask an expert.
Start typing and see existing answers.
Is this pump Hospital grade?
Best Answer: This is not considered hospital grade, but it has the efficiency, power, and performance of a hospital-strength breast pump without compromising on portability.
Is this pump compatible with Mam bottles?
Best Answer: Yes, it's compatible with Mam bottles.
Do you need a special nursing bra while pumping?
Best Answer: Any nursing bra will do!
Can I use this pump in Australia or do I need an adapter?
Best Answer: You need an adapter to use the pump in Australia.
Is this pump compatible with the wide-neck Dr. Browns bottles?
Best Answer: It is! The S1 takes standard wide mouth bottles, so bottles from Dr. Brown's will connect directly to it.
Is this Spectra compatible with Dr. Brown's bottles?
Best Answer: It isn't! You'll need to purchase the Small Cap bottle adaptor to make it possible for you to use any narrow-neck bottle with the flanges.
Does this work with Philips Avent Milk Storage bags?
Best Answer: This pump does work with the Philips Avent Milk Storage bags.
Does it have 2-year Limited Manufacturer’s Pump Warranty?
Best Answer: The warranty is offered by the manufacturer so you'd want to reach out to Spectra directly.
Are the Momcozy bags compatible without an adapter? If not, which bags are compatible without the adapters?
Best Answer: Spectra users can use Lansinoh's storage bags, which fit right onto the flanges.
Is there a way to make it hands free?
Best Answer: This isn't designed to be a hands-free-pump, but some reviews say that they use it with a hands-free bra to make it more portable.
This says you need an adapter to pump milk directly into the bags. Is that adapter available here?

Awesome Pump for Breastfeeding Mamas
This made my breastfeeding journey so easy and efficient. Use the pump all the time and it works like new. If you are considering exclusively breastfeeding/pumping this is for you. I rarely had clogs and never got mastitis while using this. Battery lasts me 2/3 days. Also the fact that its cordless is great especially that I pump at work or at home and do other things at the same time. Would recommend 100%

This pump was a lifesaver when my newborn didn’t nurse efficiently right away. Preserved my supply, held a decent charge, and loved that I didn’t have to be plugged into the wall.

My absolute favorite pump. This pump got me through breastfeeding my daughter. I primarily nursed her but this helped keep my mind at ease as far as my supply goes

This Pump Saved my Supply!
I highly recommend this breast pump for every mom! If you’re a first time mom, don’t waste your time with a wearable pump like I did! Wearable pumps have inconsistent suction and barely works so I basically ruined my supply. I paid out of pocket for this spectra pump and it was 100% worth it. It has hospital grade suction and it improved my low supply in just days! Very easy to use, battery lasts a couple days and it has very intuitive settings. Love the massage mode and expression mode which…

Only Reason I’m still Pumping
The best pump you could buy on your pumping journey. I have been exclusively pumping for 4 months now and my son drinks 34+oz a day. The spectra pulls the most milk out of the three pumps that I have tried so far. The spectra has allowed me to feed exclusive breastmilk and not have to supplement with formula. They call it a workhorse for a reason. The only con is that it’s bulky, so it’s kind of annoying to take places, but worth it to bring because it will empty me in 15-20 min. Just make sure…

Fantastic
Worth the extra money for the chargeable version. I get great output with this and use it multiple times per day. Reliable.

Primary Pump as an EP
This is my primary pump. I'm happy I spent the extra for the rechargeable model, and it stays charged for 24-36 hours of pumping. I have preferred the Spectra to the hospital grade Medela. As an exclusive pumper, the diaphragms and valves must be replaced fairly often (every 2-4 weeks). I purchased flange inserts for a better fit.
