Spectra S1 vs S2 Breast Pump Comparison Guide

Looking at getting a breast pump but wondering whether to get the Spectra S1 Plus or the Spectra S2 Plus? This guide gives you a comparison of the Spectra S1 vs S2 so you can make the best decision for you.

Which is better, Spectra S1 or S2?

The Spectra S1 Plus is better, in my opinion, because it gives you more freedom since it is rechargeable. If you think you will need a portable breast pump at any time during your breastfeeding journey, get the S1 Plus.

The rechargeable battery gives you the freedom to pump away from a power source for up to 3-4 full pumping sessions, great for power pumping. The Spectra S1 Plus is worth the extra cost for the rechargeable battery.

FAQ’s for Spectra Breast Pumps

1. How are the Spectra S1 Plus and Spectra S2 Plus models similar?

Both pumps have these key features:

  • Ultra-Quiet Motor
  • Massage Mode and Expression Mode
  • Adjustable Suction Levels
  • Night Light
  • Auto-Timer with Display
  • Closed System Pump
  • Backflow Protector
  • 2-year Warranty on Pump
  • Single or Double Pump Capability
  • Size Dimensions: 7.9 x 7.9 x 6.7 inches

2. How are the Spectra S1 Plus and the Spectra S2 Plus models different?

One of the differences between the S1 and the S2 is the color. The S1 is blue, and the S2 is pink. The other main difference between the two pumps and the extra cost on the S1 is the rechargeable battery.

The S1 comes with a rechargeable battery, so it gives you the freedom of being able to pump anywhere. You can get about 3-4 full pumping sessions out of it before it needs to be recharged. The Spectra S2 must plug in to use; it does not have a battery. 

3. Why get a Spectra Breast Pump?

Spectra Baby USA is owned and run by board-certified lactation consultants and registered nurses who are also all moms. It is a mommy-owned company providing you with products that support you in your journey of breastfeeding. They are committed to being there for you every step of the way. 

One of the great features of any Spectra pump is that they have Natural Nursing Technology. Natural Nursing Technology allows the pump to mimic the natural breastfeeding experience as closely as possible. The pumps are super quiet, and you can adjust the suction levels for a more comfortable pumping experience. 

4. How do the Spectra pumps compare to Medela pumps?

Most moms that have tried both Medela pumps and Spectra pumps prefer the Spectra pumps. Spectra breast pumps are a lot quieter, making it easy to pump at night or when the baby is napping. They are also more than half the weight of most Medela pumps, so they can easily travel with or take to work. 

The best thing about Spectra pumps vs. Medela pumps is that the Spectra pumps have adjustable suction levels. This makes the pump more customizable for each mother and leads to a more comfortable pumping experience. 

The spectra pumps also have a digital timer and automatic shutoff capability.

5. Should I buy the S1 or S2?

The Spectra S1 Plus is worth the extra cost for the rechargeable battery. However, if you know that you will always be near a power source and don’t mind plugging in for every pumping session, the Spectra S2 Plus will work just fine. I like the portability of the S1 and like knowing that I could pump without plugging in when I need to. I recommend getting the S1 over the S2.

6. How long does it take to charge Spectra S1?

The Spectra S1 takes about 4 hours to charge fully. A battery indicator that displays 4 bars means there are approximately 3 hours of operating time; 1 bar indicates 1 hour of operating time left. When the battery indicator is flashing, you have about 20 mins of operating time left. 

7. Does insurance cover a Spectra breast pump?

Your insurance provider will cover a breast pump at no cost to you. You can find out what breast pump you are allowed through your insurance provider with these insurance look-up tools.

With Edgepark, you enter where you live and your insurance provider then you see the breast pumps available to you.

Aeroflow is another site that will tell you what breast pumps your insurance provider covers, as well as some other motherhood essentials.

Or you can use the Spectra insurance look-up tool to see if your insurance provider will cover a Spectra Breast Pump.

8. Can you sterilize pump parts in a bottle sterilizer?

Yes, you can sterilize pump parts in a microwavable sanitizing bag or a microwave sterilizer or electric steamer sanitizer for bottles. Be sure to follow manufacturer recommendations on the sterilizer. 

9. Are the Spectra pumps hospital-grade pumps?

The term ‘hospital-grade pump’ does not have a universal definition that the FDA recognizes. Traditionally hospital-grade pumps are extremely bulky, heavy, expensive, and can be used by multiple users.

Spectra considers their pumps hospital-grade because they can be used by multiple users and can support a need to pump frequently for an extended amount of time. They are also way more portable and affordable for home use than the ones used in a hospital.

Conclusion

Spectra S1 vs S2: The Difference

The Spectra S1 and S2 Breast Pumps are very similar in all of their key features. They both have adjustable suction, a built-in night light, ultra-quiet motor, single and double breast pumping capability, and have different modes.

The main difference aside from the color is the rechargeable battery which is only available on the S1 Plus. The S2 Plus needs to be plugged in for every pumping session. The freedom to pump 3-4 full sessions away from a power source is perfect for the everyday mother, so I think the S1 Plus is the better choice.
