Spectra S1 Double Electric Breast Pump Review

spectra s1 breast pump reviewThis pump has it all – amazing functionality, easy portability, and great price considering its efficacy. It also looks like an adorable kettlebell. And who doesn’t love the Spectra slogan “our pumps don’t suck, they suckle!” This Spectra S1 breast pump review will detail everything I love (and what I don’t love) about the S1 pump.

After I became a mom and pumped regularly at work, I started hearing about Spectra. They are a well known brand in Asia, but they’ve only been available in the US market since 2013. Information was hard to come by and as I experimented with different pumps, so I skipped over the Spectra in favor of familiar brands like Medela and Philips Avent.

Finally, a close friend purchased a Spectra so I could try one first hand. I was instantly converted! I had been satisfied pumping daily with my Ameda Purely Yours, but from the moment I laid eyes on the Spectra, my breastfeeding and pumping life wasn’t the same.

What’s in the box?

The Spectra S1 pump comes in a box with everything you need to pump and feed your baby. The pump motor comes with a built-in rechargeable battery, so no additional battery purchase is needed.

  • 2 breast pump bodies (each is one piece and includes the breastshield/ flange and connector to milk collection bottle)
  • 2 milk flow valves that attach to the pump bodies
  • 2 diaphragms, which attach between breast pump body and tubing
  • 2 pieces of tubing
  • 2 milk collection bottles (5oz/160mL size)
  • 2 nipples/ teats for feeding (with covers)
  • Motor unit with rechargeable battery
  • AC adapter for charging
  • Instruction manual

Spectra S1 Double Electric Breast Pump Pros: 

  • Closed System – this is the most hygienic option, saves you cleaning time (no need to clean tubing), and it means you could lend or sell your used pump without concerns of bacteria growing in the motor.
  • Quiet – it makes a bit of noise, but it is slightly quieter than Medela, Ameda, and Philips Avent. This was important to me since I pump at work and occasionally need to take calls during a pumping session.
  • Excellent massage feature to stimulate letdown – as they say, this pump doesn’t suck, it suckles. The pump helps stimulate letdown really quickly so your overall pumping session is shorter.
  • Independent suction speed and vacuum controls – you can adjust the settings to mimic the suckling of your baby, thus allowing you to pump quickly and thoroughly. I also prefer pumps with independent controls because they are the most comfortable – you can set the vacuum strength to what is comfortable for you and choose the speed that helps you express the most milk.
  • Digital display – allows you to see settings at a glance, and pump in the dark if you’re near your sleeping little one. It is helpful to see the amount of time you’ve been pumping. It was easy for me to lose track of time if I was working while pumping.
  • Rechargeable battery – You can pump away from power outlets or on the go. The suction strength seemed the same to me when operating on battery. 
  • Can use as a single pump if needed – This is a feature offered by most double pumps. It is useful if you, for example, have just fed or plan to feed with one breast but would like to pump the other. Or, you can pump one breast while directly feeding with the other.
Spectra S2. Same as S1, but without internal battery (runs on AC Power only)

Spectra S1 Double Electric Breast Pump Cons:

  • Does not come with a carrying case or cooler bag – I do not see this as a huge negative as I prefer to carry my pump and accessories in a bag that matches my style. Any small cooler bag/ lunch box with an ice box will do to store your expressed milk.
  • The flange sizes are less varied than other brands (only 24mm-32mm vs. Medela’s 21mm – 36mm). However, the sizes available will fit most women.
  • Spare parts can be harder to come by as they are not widely stocked in stores like Medela parts. This said, you can easily order the parts online, there just aren’t quite as many online vendors with the parts, either.
  • Spectra does not offer a car adapter – you can buy an aftermarket brand, though

Should you buy the Spectra S1 Double Electric Breast Pump?

Yes! You should buy the Spectra S1. It’s great! For anyone who needs to express their milk quickly and in quantity, this is the ideal pump. It is a little heavy to carry around, but it is so quiet and so effective! Highly recommended as well for ease of use – it is incredibly easy to adjust the settings and the digital display lets you know where you’re at. Also, you can’t beat the hygiene since it is a closed system. Interested? View details or buy on Amazon!
