Spectra  S1 Vs. Spectra S2

There are hospital-grade pumps in the form of the Spectra S1 and S2. Pumping exclusively or having a poor milk production is a common reason for mothers to use these pumps since they are strong, efficient, and very adaptable. Spectra pumps are powerful enough to boost milk production and keep it stable.

Compared to hospital-issue breast pumps, they are also smaller, lighter, and less expensive.

It is the robustness and extended motor life of Spectra pumps that set them apart. For those who anticipate regular pumping and/or future children, they are the best alternative instead of renting a pump from the hospital.

If you’re looking for the most comfort and output from your pumping sessions, which Spectra model is best? Let’s take a closer look at these two examples side by side: Both the S1 and S2 versions are available.

Factors to Consider Before Deciding for a Breast Pump 

It’s nerve-wracking to buy a breast pump, particularly if you intend on pumping your milk exclusively. You’ll be hooked up to your pump for two hours a day, but you can’t always view or test it before you purchase it.

What aspects are most essential to you will help you select which pump is ideal for your needs. An example may be:

  • Mobility: How much space is needed, and whether or not an outlet is necessary
  • The Noise: Being able to pump while on the phone, for example
  • Timers, settings, and other usability features
  • Your budget

A massage mode is available, as well as 12 different degrees of intensity.

While the Spectra S1 includes a rechargeable battery, the design of this pump is very similar to that of its twin, the Spectra S2, which does not.

In either a single or double pump setup, the S2’s attachments are interchangeable.

Hospital-grade quality and backflow prevention are included, as well as a nightlight for enhanced safety and convenience.

Breast Pump S1 vs. S2: A Comparison of Features

There are many similarities between the Spectra 1 and Spectra 2 breast pumps, two hospital-grade breast pumps. However, there are a few distinctions between them that you should be aware of before settling on a purchase.

The Spectra S1 breast pump contains a built-in battery, making it more convenient for on-the-go use, but the Spectra S2 does not. The Spectra S1 Plus may be used without the need for an electrical connection. S1 Spectra pumps are more expensive because of this added functionality.

Two further, subtle distinctions exist: Compared to the larger and blue S1 pump, the Spectra S2 is more compact and pink.

Similarities of Spectra S1 Vs. S2 Breast Pumps

A hospital-grade suction pump, the Spectra S1 Plus and S2 Plus are packed with power (270 mmHg). The vacuum and the cycle speed may be adjusted to suit your particular preferences with each pump.

Flanges of 28mm and 24mm are included with both Spectra pumps. If you find these shields too big for you, you can always adjust to smaller shields. Fortunately, Spectra sells flanges in two different sizes: 32mm and 20mm. Spectra wide-neck milk bottles may be attached to the bottle connectors and the flanges as a single piece.

A Single Pump or a Dual Pump

You may pump both breasts at the same time with the Spectra S1 and S2 breast pumps. It’s easier and quicker to express milk from both sides simultaneously.

You may even nurse on one breast while draining the other.

Scientific studies have shown that utilizing a double pump instead of a single pump for alternating pumping may increase the amount of milk a mother produces by about 20%. As a result, this milk is higher in calories and nutritional value since it has a higher percentage of fats.

Closed System with a Backflow Prevention

The closed system of the Spectra S1 Plus and Spectra S2 Plus sets them distinct from different electric breast pumps. The suction tubes are safe from contamination due to the built-in backflow control that prevents milk from flowing backwards. This is a critical function, as it keeps the pumping sessions clean and healthy for both mom and baby by preventing contamination.Backflow prevention keeps viruses, bacteria and molds away from pump components. No matter whatever model you choose, Spectra S1 or S2 will allow you to make adjustments.

Different Techniques for Expression Massage

The power of Spectra S2 is comparable to that of Spectra S1. Each pump features a massage mode that simulates the first phase of pumping, and an expression mode that mimics the second phase. The rate of vibration in the massage mode is 70 hertz. During this time, you may adjust the suction power from 1 to 5 but not the speed.

During expression, you may alter the suction intensity anywhere between 38 and 54 CPM, or from 1 to 12. Both the Spectra S1 Plus and the Spectra S2 Plus have suction levels that are very close to level 12, the maximum level to which hospital pumps are capable of sucking.

This electric pump does not automatically toggle between the Massage and Expression settings. Click the mode button once to switch to expression mode at the first sign of milk let-down. Massage and Expression modes on the Spectra S1 Plus and S2 Plus are fully customizable, down to the ability to switch between them mid-session. The Massage Mode may be used at one of five different intensity levels. In Expression Mode, a total of twelve expression levels (up to 270 mmHg) are available for each pump. During Expression, you are allowed to make adjustments to the tempo.

When running on battery power, the Spectra 1’s suction may be somewhat lower than that of the Spectra 2 to avoid draining the battery too quickly.

Reliable And Silent Motor

Spectra breast pumps are very quiet. However, Spectra is an exception among the often loud medical pumps. It has powerful suction yet is surprisingly quiet. This electric pump isn’t fully quiet, but it gives you greater control over its operation.

With a predicted lifespan of 1500 motor hours, the Spectra S1 and S2 breast pumps outlast any other pump available. This outstanding outcome makes Spectra a great investment due to its extreme durability.


The Spectra S1 and Spectra S2 Breast Pumps both have illumination systems built right in. At night, it’s far less complicated and more convenient to use the pump.

Differences of Spectra S Vs. S2

While there are many similarities between the Spectra S1 and S2 breast pumps, there are also many distinctions that make the S1 and S2 two entirely separate breast pumps.

In-Cell Battery

The battery is the most significant distinction between the S1 and S2. In terms of mobility and reuse, the Spectra S1’s rechargeable battery is unbeatable.

The S1 breast pump includes a rechargeable lithium-ion battery that makes it easy to carry with you and pump wherever you need to go, whereas the S2 breast pump needs an AC adaptor.

If you need to go to work or out for the day, you may use the Spectra S1 to pump at any time and in any location. However, the S2 lacks rechargeable batteries, so you’ll need to locate a power source to operate it. As a result, it’s very hard to use the S2 outside of your house in perfect anonymity.

As long as you have privacy and adequate battery power, you can pump anywhere with the S1.

Even if the lithium-ion battery dies while you’re on the road, you can easily recharge it thanks to its rechargeable nature. The S1’s battery can last up to three hours when completely charged, so you won’t have to worry about running out of milk in the middle of the day to keep pumping throughout the day.

It’s far simpler to recharge your breast pump in a public location rather than attempt to use one if you ever find yourself without a functioning S1 battery. It’s now possible for women who have to return to work or travel but still need to pump to do so with the S1.


In contrast to the S2, the S1 features a rechargeable battery, making it more easier to use. The fact that you can pump wherever you want as long as you have privacy and adequate battery power has already been touched on, but it also means that you aren’t tied to a wall when you do the pumping, as we indicated above.

When using the S1 at home, you may stand up and walk about while still connected to the breast pump. While pumping, if your baby needs you, you may go to them and provide comfort. You can’t walk about with the S2 since it has to be connected into an outlet to be used, which means you’re trapped pumping with it. Due to the AC adaptor, it is almost tethered to the wall.

As such, when it comes to pumping, the S1 is a terrific option for women who want to multitask while doing so.

The Weight

Even while the S1 breast pump is smaller and lighter than the other, it is also the most cumbersome. Weight differences between the Spectra S1 and S2 are negligible.

Because most portable breast pumps are supposed to be lighter than their non-portable equivalents, this disparity is unexpected.

The Spectra S1 and S2 are reversed in this design element, which is to make it easier to carry about and utilize for hands-free pumping. It is worth noting, however, that both breast pumps are quite light, even though the S2 is the heaviest of the two. Both the S1 and S2 are quite light in comparison to other breast pumps on the market.


This is a significant distinction, which you may have already noticed.

There is a blue Spectra S1 and a pink Spectra S2, both of which are soothing. You won’t be able to get the S1 or S2 in pink or blue since they are the only colors offered for each breast pump.

Even while color isn’t always the decisive factor when it comes to picking breast pumps, it might be for some women who find the other distinctions mentioned inconvenient.


Both the Spectra S1 and S2 cost the same, however the S2 is a more affordable alternative.

Conclusions on the Spectra s1 Vs. s2 

The Spectra S1 and S2 have many similarities and differences, but which one is better?

That truly depends on whether or not you need a portable breast pump.

While the s1 is an excellent travel pump, it lacks the stealth of the Spectra s9.

Consequently, if we had to select between the S1 and S2 versions of the Spectrum, we would choose the S2 model since it was less expensive.

It’s our goal that our Spectra breast pump guide has helped you make an informed decision.
