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.

Is this pump compatible with the Mason milk storage glass containers?
Best Answer: Yes, but not directly out of the box. The Spectra S1 Plus is not directly compatible with Mason Bottle glass storage containers.
Does the battery come with the Spectra S1 plus? If not, what kind of battery does it use? Where do I buy the battery? And how much is the battery?
Best Answer: The battery is in the pump -- you do not need to purchase it separately.
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.
This says you need an adapter to pump milk directly into the bags. Is that adapter available here?

So, I had a hands free pump from another company to begin with and it broke 2 days in. My baby was not latching and I was in a PANIC to get a pump that worked great and would last. I ran to the nearest target and got this one based on reviews and let me tell you it is a LIFESAVER. I got great output (way more than I did with my original) and it has so much of an easier assembly. I cannot say enough good things about this pump. If you are a first time mom, I also highly recommend this.

Let me start with spectra s1 is the top of the line! I have two spectra s1 , one for down stairs and one for upstairs. 100% primary pump! I can honestly say with the correct flange and my comfort suction setting spectra pulls has milked the most oz in one session 🫶🏻 thank you spectra for such an awesome product and making it possible for me to donate ! Blessed thank you 🫶🏻

Good Pump
I ordered wearable breast pumps through my insurance while pregnant. After giving birth, I quickly realized I was an overproducer and needed a good wall pump. I love the Spectra S1! It does a great job emptying me out & I love the option of being rechargeable. I feel more portable and find myself bringing my pump all over my house: the bathroom while getting ready, the bedroom for early morning pumps, the kitchen while eating. It holds the charge for a good amount of time. Well worth the money! I would repurchase again!

From Drops to Dairy Queen 👑
First time mom here! I originally wanted a hands free pump like momcozy, Elvie stride plus, willow 360 and so on. I settled on the Elvie stride plus paying a pretty penny for it. After 3 weeks of exclusively breast feeding my little dude the pediatrician/lactation consultant gave me the okay to start pumping. I started with tandem pumping once a day and slowly moved up to three times a day. The amount of milk the Elvie stride was pulling absolutely deflated my belief that I had enough supply for…

Reliable, Comfortable, and Perfect for Pumping at home and occasionally on the go
I’ve used multiple pumps over the years, and the Spectra S1 Plus has not disappointed me at all. It’s reliable, quiet, and comfortable. The suction is strong yet gentle, and it allows me to efficiently express milk without discomfort. I appreciate the adjustable settings, nightlight, and rechargeable battery, which make it perfect for both home use and on-the-go pumping.It works seamlessly with my Maymom flange and duckbill set, which is important for ensuring proper fit and milk flow. I needed…

Pump
Great pump I would prefer the S1 than the S2. Used it with my first born now I'm using it with my second born.

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.
