Spectra Pump Range
Spectra has built a strong reputation for creating powerful, reliable breast pumps trusted by both moms and lactation professionals around the world. Their range includes everything from lightweight portable options to hospital-grade double electric pumps designed for exclusive pumping.
Currently, the most well-known Spectra breast pumps include:
- Spectra S1 Plus
- Spectra S2 Plus
- Spectra 9 Plus
- Spectra Synergy Gold
- Spectra Synergy Gold Portable
- Spectra Wearable Breast Pump
While all Spectra pumps are built around the brand’s signature quiet motor, closed system hygiene, and gentle yet effective suction, each model brings its own unique features designed to suit different pumping routines.
So, what sets each Spectra pump apart?
Let’s dive into the comparison and take a closer look at each one.
Spectra S1 Plus
The Spectra S1 Plus is one of the most popular and highly recommended breast pumps in the Spectra range—and for good reason. With hospital-grade strength, a rechargeable battery, and ultra-quiet operation, the S1 Plus is designed for moms who need reliable, efficient pumping at home or on the go.
It’s a closed system pump, which means you don’t have to worry about milk backing up into the tubing or motor—a must-have for hygiene and peace of mind.
At a snapshot, the Spectra S1 Plus offers:
- Hospital-grade suction up to 270mmHg
- 2 pumping modes – stimulation and expression
- 12 suction levels
- Cycle speed control for customized rhythm
- Closed system for hygiene
- Quiet motor – only 45 dB
- Rechargeable battery (approx. 3 hours of use)
- Digital LCD screen with timer and night light
- Double or single pumping option
- Compatible with Spectra wide-neck bottles and flanges
What I love most about the S1 Plus is how customizable it is—you can adjust both suction and cycle speed independently, which gives you more control over comfort and milk flow. It’s also incredibly quiet, which makes it ideal for night pumping or discreet use at work.
Compared to the Spectra S2 vs the S1 has one major advantage: portability. The built-in rechargeable battery means you’re not tethered to a power outlet, making it a great choice for busy moms or those pumping in multiple locations.

Spectra S2 Plus
If you’re after hospital-grade performance without the need for portability, then the Spectra S2 Plus is a fantastic choice. It offers nearly all the same features as the S1 Plus—like strong suction, adjustable settings, and whisper-quiet operation—but at a more budget-friendly price point.
The main difference? The S2 Plus doesn’t come with a rechargeable battery, so it needs to be plugged into a power outlet during use. That makes it ideal for moms who mostly pump at home or at a designated spot at work.
At a snapshot, the Spectra S2 Plus offers:
- Hospital-grade suction up to 270mmHg
- 2 pumping modes – stimulation and expression
- 12 suction levels
- Cycle speed control
- Closed system for backflow protection
- Quiet motor – only 45 dB
- Digital LCD screen with timer and night light
- Double or single pumping option
- Plug-in only (no built-in battery)
What I appreciate about the S2 is that it delivers the same customizable pumping experience as the S1, just without the added cost of a battery. So if you don’t need mobility, it’s a great way to get the power and comfort of a Spectra pump at a lower price.
The S2 Plus is especially popular with exclusive pumpers who want a strong, efficient pump for home use and don’t mind staying plugged in during sessions.
Spectra 9 Plus
The Spectra 9 Plus is the most compact and portable pump in the Spectra range, making it a great option for moms who need something lightweight and discreet for on-the-go pumping. Unlike the S1 and S2, which are a bit bulkier, the 9 Plus is small enough to fit in your hand or pop into a handbag.
It’s a double electric pump with a built-in rechargeable battery, so you’re not tied to a power outlet—perfect for work, travel, or pumping between errands.
At a snapshot, the Spectra 9 Plus offers:
- Suction strength up to 260mmHg
- 2 pumping modes – stimulation and expression
- 10 suction levels
- Compact, handheld design
- Built-in rechargeable battery (up to 2 hours use)
- Digital screen with timer
- Quiet operation
- Closed system for hygiene
- Double or single pumping option
While it’s not quite as powerful or customizable as the S1 or S2, the 9 Plus is ideal if you value portability and simplicity over advanced settings. It’s a great second pump for travel or work, or a primary pump for moms who don’t need hospital-grade strength but still want reliable performance.
If you’re frequently on the move and don’t want to carry a bulky motor around, the Spectra 9 Plus might be the most convenient choice in the lineup.
Spectra Synergy Gold
The Spectra Synergy Gold is Spectra’s most advanced breast pump, designed with dual-motor technology that allows you to control the suction strength and cycle speed on each breast independently. This is a game-changer for moms who experience different milk flow or sensitivity levels between sides.
It’s considered a premium hospital-grade pump and is ideal for exclusive pumpers, moms with medical or supply concerns, or those who simply want more precision and comfort in their pumping sessions.
At a snapshot, the Spectra Synergy Gold offers:
- Dual-motor system for independent left/right control
- Suction strength up to 270mmHg
- 2 pumping modes – stimulation and expression
- 15 suction levels
- Adjustable cycle speeds per side
- Quiet motor with gentle start
- LED screen with timer
- Closed system for hygiene
- Plug-in only (no battery option)
- Recommended for frequent or exclusive pumping
What makes the Synergy Gold really stand out is the customizable control over each breast. This means you can fine-tune the pump to match your body’s natural rhythm and comfort, which can be especially helpful if you’re dealing with oversupply, engorgement, or uneven milk output.
It’s not the most portable pump in the range, and it does come at a higher price point, but for moms who need or want the most advanced functionality, the Synergy Gold delivers on performance and comfort.
Spectra Synergy Gold Portable
The Spectra Synergy Gold Portable is a newer addition to the Spectra lineup, combining the customizable power of the Synergy Gold with a more compact, lightweight design. It features dual-motor technology—just like the Synergy Gold—so you can adjust the suction and cycle speed separately on each side, but it’s made with portability in mind.
Unlike the original Synergy Gold, this model includes a built-in rechargeable battery, making it a great option for moms who want flexibility and advanced features without being tethered to an outlet.
At a snapshot, the Spectra SG Portable offers:
- Dual-motor system with left/right control
- Suction strength up to 270mmHg
- 2 pumping modes – stimulation and expression
- 15 suction levels
- Adjustable cycle speed on each side
- Built-in rechargeable battery (approx. 2 hours use)
- Quiet motor with soft startup
- Digital display with timer
- Closed system design
- Lightweight and travel-friendly
The SG Portable is ideal for moms who love the idea of independent control but don’t want to sacrifice mobility. It’s a great fit for exclusive pumpers, working moms, or anyone who wants the power of a hospital-grade pump in a more practical, portable package.
If you liked the concept of the Synergy Gold but need something easier to travel with, the SG Portable is definitely worth considering.
Spectra Wearable Breast Pump
The Spectra Wearable Breast Pump is the newest innovation from Spectra—and their first truly all-in-one wearable model. Designed for busy moms who want the freedom to pump hands-free and cord-free, this pump fits directly in your bra, so you can move around with ease while you express milk.
Unlike Spectra’s traditional pumps with external motors and tubing, this wearable design is compact, quiet, and designed for discreet use whether you’re at work, running errands, or multitasking at home.
At a snapshot, the Spectra Wearable Breast Pump offers:
- All-in-one cordless, tubeless wearable design
- Suction strength up to 280mmHg
- 3 pumping modes – stimulation, expression, and mixed
- 5 suction levels per mode
- Lightweight motor – only 225g
- 4oz collection cups with measurement markings
- Digital display with timer
- Closed system with backflow protection
- Built-in rechargeable battery (approx. 2.5 hours use)
- USB-C charging
- Quiet operation for discreet pumping
This pump is ideal for moms looking for true mobility without compromising Spectra’s hospital-grade strength. While it’s not as customizable as the dual-motor models, it offers the kind of hands-free convenience that many moms find essential—especially during busy days or nighttime pumping.
If you love Spectra’s reliability but want something wearable and truly on-the-go, this is the pump to consider.
The Verdict: Which is the Best Spectra Pump
When it comes to finding the best Spectra pump, it really depends on your pumping needs, lifestyle, and how much flexibility you’re looking for.
If you’re after hospital-grade strength with portability, the Spectra S1 Plus is my top pick. I think it is a fantastic all-rounder. It’s powerful, quiet, and comes with a built-in rechargeable battery, making it a great option for both home and on-the-go pumping.
If you don’t need mobility and want to save a little, the Spectra S2 Plus offers the same performance and features—just without the battery. It’s a great budget-friendly choice for pumping at home.
For something compact and travel-friendly, the Spectra 9 Plus is perfect for moms who need a lightweight option. While it’s not as strong or customizable as the S1 or S2, it offers a solid balance of portability and performance.
If customization and comfort are your top priorities, the Spectra Synergy Gold and SG Portable stand out with their dual-motor technology. For those who want independent suction control on each side—and a truly tailored pumping experience—these are the top choices. If you need portability, the SG Portable gives you the same great features in a more flexible, battery-powered design.
And for hands-free pumping, the Spectra Wearable Breast Pump delivers true convenience without sacrificing strength. It’s a great option for busy moms who want to pump discreetly while getting things done.
Whichever Spectra pump you choose, you’re getting a quiet, reliable, closed-system pump designed to support your breastfeeding journey every step of the way.
