Spectra Baby USA Double/Single Breast Pump with Rechargeable Battery, 3.3 Pound

Spectra Baby USA Double/Single Breast Pump with Rechargeable Battery, 3.3 Pound

The S1 boasts so many great features, including an inbuilt rechargeable battery and is designed to truly meet the needs of moms wanting to feel confident that they have an effective, powerful breast pump to support supply while also incorporating features to make life a little easier. Like all Spectra pumps, the S1 is a closed system – a physical barrier between the milk and the pump ensures hygiene and motor performance. The S1 is intended to rival the Medela Symphony, and even surpass it with some of its innovative features designed to make life easier for moms. The S1 is hospital grade – strong and efficient enough to support milk supply. Used in hospitals to establish a milk supply for moms with premise. With a maximum suction strength of 350mmHg and the ability to be used as a single or double pump, plus a host of additional features, the S1, like her sister the S2, is set to become the ultimate breast pump to support U.S. moms. Completely flexible, touch button with the S1 pump’s digital controls. These allow you to set the pumping program to the speed and rhythm most effective for your body. The pump will start in ‘massage mode’, a short, shallow mode designed to stimulate your body’s letdown reflex (start the milk flowing) just like how your baby tells your body to start milk flow. The pump will then switch to expression mode, a deeper, slower pattern of suction which mimics how your baby nurses when the milk is flowing. For women who find it hard to get a letdown when pumping, this feature really helps – switch back and forth as needed. The suction is also adjustable whether in let-down or expression mode. Includes a timer and nightlight. You can see on the picture that you can adjust both cycle (how often the pump ‘sucks’) and vacuum (the strength of the suction) easily, and the digital display allows you to see your program at a glance. Can be used with it’s inbuilt battery for 1 hour on full charge or plug it in…it’s up to you.

Main features

  • Closed system – hygienic for you and baby
  • Night light and timer, Super quiet, Letdown mode and fully adjustable program to best suit your body
  • Everything you need for double pumping
  • Powerful, adjustable suction yet so comfortable you won’t realize how powerful it is. If the pump is making a loud noise please make sure that it is on a flat and level surface as this may cause unwanted noise due to the angle of the pump piston. The next step is to ensure that the tubing is fully on the pump and that there is no kinks or sharp turns in the tubing as this may cut off suction. After those two things the loud noise is usually fixed, however, sometimes the back flow protectors or duck bill valves can cause this issue. So please ensure that they are properly fit

Updated review- returning the S1

UPDATE- I’m leaving 2 stars on this product for customer service. I began to like this pump less and less, but Sandra @ Spectra was usually quick to help me troubleshoot. The thing is, it’s not as customize-able as I was hoping. You can’t adjust the cycles in Let Down mode, just the suction strength, and it’s too slow. About 1/2 the speed of the Symphony’s Let Down mode. The numbers for the cycles in Expression mode probably make sense when explained but I sent 2 e-mails to Sandra asking for clarification on those and didn’t get much info. The vibration/suction also made my nipples pretty sore and I would dread putting on the pump which is when I pretty much gave up. It’s quieter than the Symphony until about L5 on suction and then it’s pretty loud and vibrate-y. I do like the night light feature though. I didn’t use it while pumping but I did use it to find my TV remote at night, have enough light to plug in my cell phone, etc. I also like that the wall plug can be adapted for international use and the battery feature was wonderful.I did have to message Spectra on Facebook to get info on their return process as nobody answered me at the company e-mail, but they told me since I’m within my 2 weeks from receiving it that I can return it, so it is going back tomorrow.All in all I think it’s worth a try for anyone, given the generous return policy.ORIGINAL REVIEW-I have been using this pump for about a day now and I am pleasantly surprised by it. I am just about 12 weeks post partum and my normal workhorse pump is a Medela Symphony. I also have a Pump in Style that I use when out and about and a Medela Harmony that I don’t use often but it does have it’s place. I have also tried a Medela Swing and Medela Freestyle in the past. I am renting my Symphony month to month and wanted to buy my own but the Spectra is literally a fraction of the price and is supposed to be comparable so I decided to give it a try.First of all let me warn you to turn it on for the first time before you hook it up to yourself. Mine was on a vacuum setting of L12, the highest, and I just about flew off of the couch in pain.I don’t understand the settings or cycles. One has a cycle setting of 70 that can’t be adjusted and the vacuum settings go from 1 to 5. You get to that setting when you press the button with waves and see waves on the pump’s screen. The other has a cycle setting that can be adjusted from 38 to 54 in increments of 2. What do those numbers actually mean, and why that number range? The vacuum settings in that phase go from 1 to 12. I do prefer the Symphony’s simple 1 button 1 dial mode of phases.The sound is quieter than my Symphony. I didn’t wake my husband up when I pumped in bed this morning. It’s kind of a purring, gurgling, vibrating sound vs. the smoother sound of the Symphony.The night light is a neat feature but I don’t pump in the dark, nor do I know anyone that does. I used it last night to find a pillow that had fallen off the bed, so, yay for that I guess.It’s soooo light, even with the rechargeable battery. I read that the battery-less S2 is lighter which I can’t even imagine.There is room for 1 bottle in the bottle holder on the back. I would have preferred it to hold 2 bottles. It’s a double pump, why only one?The battery, which is supposed to last for 3 hours on a full charge, is already 1/2 gone after just 32 minutes of use. That’s not good. I love the portability though. I started pumping at the kitchen table while on my laptop and then just picked it up and moved to the living room with hubby to watch tv. The Symphony is heavier and has no battery.While pumping it kind of vibrates as it pulls your nipples, which is different. Doesn’t hurt, doesn’t feel any more comfortable than the Symphony though. It’s just different.My milk output has been about the same, possibly a touch better, but I don’t pump on a set schedule or for set times, so it’s hard to really compare that. Yesterday with the S1 I ended up with 0.5 oz more overall than the day before with the Symphony. I fluctuate around 2 oz in either direction, but I’m fine if the Spectra is simply normal for me (as long as it doesn’t hurt my supply or take forever to empty me!).I have a really hard time figuring out the settings I mentioned. I find myself fiddling with it a lot to achieve more letdowns. Again, the Medela pumps are SO much more simple in that regard.The letdown mode of the S1 (the waves mode) is probably only half as fast as the Symphony’s letdown mode, and I usually find myself staying in non-waves mode, Cycle 38, vacuum L05, for most of my pumping sessions. I have no idea what any of those settings actually mean though. I e-mailed Spectra for more clarification, as the manual appears to have been written by a Korean kindergartner and then translated by a blind man, but I haven’t heard back yet.

Great Pump!

I was a little weary since I hadn’t heard of the brand before, but since it had such great reviews I figured I’d give it a try. I had an Ameda pump and it was not that great, since upgrading to the spectra I have gotten a lot more milk during each pumping session. It’s also a lot quieter and the massage feature gets the milk flowing a lot faster then my Ameda did. Would recommend to a friend!

While others have great luck with the Medela PISA

I have been exclusively pumping for over two months now, and this pump is the only reason that I have been able to keep going. While others have great luck with the Medela PISA, it was not effective for me. I went from producing about 30 ounces per day to over 80 on this pump. The Spectra is much more gentle on my nipples (I don’t even need nipple butter or Lanolin anymore) and is much faster than the PISA. Just to compare, I went back to the PISA for a pump, and when the milk stopped flowing, I switched to my Spectra and continued to empty. If you’re planning to pump long-term, I definitely recommend the S1 with the internal battery over the S2. You can accomplish so much more when you can move around a little bit, which is especially true when you have a screaming baby!

Went with Medela

We had a medela pump that I had gotten from my sister as she was done having children. This Spectra pump was recommended by a lactation nurse but it sounded like she had some incentive to sell us this one. We ended up getting it on Amazon because it was cheaper (like everything else). It looks fantastic and stylish. By far the best "looking" pump we have had. Yet the "sucking power" on this one didnt compare to the medela. Want numbers? We took this pump, our used medela pump and a new medela pump to get tested. A pump needs to hit over 185 (dont know what unit of measurement they are using). This spectra was hitting around 200 (passing) on full power. However, the old medela we had was hitting 235 and the new medela was over 250. While this may not be ideal for everyone, it was what we were used to and only wanted to get a new pump because everyone told us not to use my sisters 5 year old pump. Ended up returning this unit in favor of the new medela. While it may be OK for some, it wasnt OK for us mainly because of the sucking power.

I cancelled returning this product!!

I used a Medela Pump in Style for 2 months that was a friend’s who wasn’t able to pump. I wanted to purchase my own pump and loved how this was totally portable and others reported this as super quiet. The Medela, even on a low setting, always hurt made me sore. During pumping I would have pain and at times would skip a pump because I just didn’t want to be in pain. After receiving this I was very disappointed at first because it wasn’t as strong as the Medela pump and I didn’t feel like it emptied my breast. So today I emailed the company and looked into returning it, but I gave it one more test and pumped for 20 minutes like I normally do, then I wanted to pump what I thought was left with the Medela pump. Low and behold, I was empty. The Medela pump only got out a couple of drops. This machine is so gentle that I honestly was so use to the searing pain of a Medela, and thought that the Spectra pump didn’t work. I cancelled my return and am keeping this pump! My only major complaint (why I only gave it 4 stars) is that I can’t turn off the "massage" feature. Because of this, the machine shakes and is noisier. Maybe I’m doing something wrong, but I’ve read the instructions and pressed the buttons and it still shakes.Pros: portable, gentle, effective, quieter than Medela (but it still does sound like a pump)Cons: parts are expensive (but I knew that and it does work with Medela parts), you don’t get a lot of bottles or any spare parts for what you are spending, I can’t turn off the "massage" feature.Please post if I’m doing something wrong with the massage feature!

Highly recommended!

I was hesitant to buy this because it’s not a common name like Medela or Ameda. But buying this has been one of the better decisions I have made recently! This pump is more powerful than you will ever need and it’s lightweight. Doesn’t really come with great instructions but it is easy to figure out. It is not as quiet as I expected but it isn’t loud either; sounds like a repetitive loud cat purring or dog growling. The nightlight feature is cool but I never need it.Two weeks post partum, overall when compared to my pumping sessions with my Medela Advance, the Spectra yields a little more milk. With the Medela I may get 4oz in a session but with the Spectra I can get up to 5oz. Not a HUGE difference but for those of us struggling with milk supply issues, every drop counts.My only criticism of the system is it only comes with one set of flanges so if you have larger nipples you will need to buy extra flanges from them which will cost you about $35.

In the past I have used various brands of manual pumps and electric breast pumps. I have rented hospital grade amedas and owned a medela pump in style tote, nothing compares!!First of all, Spectra is compact. Comes with a night light which is handy when I’m pumping and putting my other child to bed. Has a handle so you don’t have to fumble and its cool design.Secondly, the pump is strong and you can control the speeds and the pull. I can’t believe I didn’t buy one sooner!! I really love the back flow membrane that is washable and prevents the milk from getting into the pump. That is something you will NEVER have to worry about. So I can even lend my pump to a girlfriend as long as she has her own collection kit. How amazing is that!?!And thirdly, they have amazing customer service. I had an issue with my pump, emailed them directly and they honored their warranty and sent me a pump within a few days. Now that is a relief especially when you have an infant and need to pump.Splurge and get this. I still think it is a better deal than the other brands.

My favorite baby buy!

You’ve found it!- the perfect pump!!I love this! I use it everyday. It is perfect for returning to work. Everything the rave reviews claim is true- quiet, strong, effective, easy, pretty- it’s great! My favorite thing is the backflow system- I never have to clean the tubing because the system never fails.

so far so good…

i purchased my spectra s1 in december when my first pump died and finally able to sit and write a well-deserved review. a bit of background, i’m a first-time mom and labor & delivery nurse. i’m still nursing my 7-month old son and going strong thanks to my spectra S1. i really did a lot of research on pumps and placed my lifestyle routine into heavy consideration. a big part of that was mobility and being able to pump with out a power source. thanks to the rechargeable battery, i’m able to do just that. i purchased this pump with the pumping pals inserts as suggested by another reviewer and found the combination excellent in helping build and maintain my freezer stash. even though my son is about to start solids, he still drinks breast milk as his primary source before eating especially since we are doing baby-led weening. i’ve also been able to compare this pump with a hospital-grade pump we use on my floor and it’s pretty much the same in comparison, except the $2000 price difference. hehe.what i love about this pump:-customer service is great when it comes to parts and questions, which is key with a lot of products. I’ve dealt with heidi and she’s been great with getting what i needed to me fast-portability with the rechargeable battery-it’s light weight, compared to some other brands of the same price-it’s quiet, compared to another pump i had that crapped out on me which sounded like a jack hammer!-less parts to clean!! omg, i didn’t think i’d complain about this with my first one, but when i really started to develop a routine waiting for parts to dry and piece together at whatever hour got ridiculous and cumbersome-night light is pretty neat for night/early morning pumping before work – this is great when i want to pump and nurse my son a the same time. pumping and nursing done together has yielded the most amount of milk for me, so when i can, i try to do this in the mornings to keep up with my stashmy only critique: a bag or tote would have been nice. i happen to inherit a breast pump bag from a friend and use that. otherwise any other bag would work. just be careful the ON button isn’t pressed by accident or the battery will drain out. the website is tricky to navigate, so i just email customer service directly.all this said, i hope people considering pumping for whatever reason really consider this pump. breast feeding is a challenge that can be overcome with help and advice. if there’s any questions, i’d love to help. happy bf’ing!! =)

I wanted to wait a few days before posting my review of this amazing product just so I could make sure I had used all the functions before giving my review. The product is awesome. I have now used three different pumps other than this one… and this one is by far my favorite. Like other reviews said the flanges on the inside of the pump are different than those of the Medela. However they are the exact same of the Evenflo pump that I have. And the Medela ones work in this pump so if you prefer those, you can always replace them with the Medela ones if you’d like. I like that it’s one less plastic part I have to keep track of. I’m going to also mention I hate pumping. If I could afford to not, I would’ve stopped a long time ago. I am exclusively pumping also, so it takes up a lot of my time. I am always looking for something to make my life easier as far as pumping. Like I mentioned I have used two different Medela pumps and an evenflo pump. I love that this is a hospital grade pump for less than 500 dollars. It is cute in its design, I’m not embarrassed by carrying it around. If you’re running late in the morning, it’s easy to go get your breakfast or do your make up or other things while pumping with the rechargable battery. It is very quiet. It has some sound, and it does sound a little weird… but I love that I can watch tv while pumping and I’m not bothering my boyfriend while I pump. I love that the breast shields are angled, unlike any other pump I have ever used. You don’t have to worry about milk piling up or rolling down the front of my body (I really hate that)!! I can’t tell you how many times i’ve been at work and gotten breast milk all over my work clothes, no matter how careful I try to be. They are easy to wash, they have less crevices than the breast shields I have currently. I love the night light feature even though it’s not really necessary. I love the suction strength. The first night I used it I had just breast fed my baby (because I was rushing home from work and didn’t have any milk ready for her) and then pumped after and still was able to get 90ML after breastfeeding which I thought was great. I LOVE the timer. I am terrible about knowing when I’ve sat down to pump. Especially when I’m tired at night time. I like that it makes my life so much easier.I haven’t had mine for very long, so I cannot answer to the longevity of this pump… but I hope that it would last by the amount of money that was spent. It also seems very sturdy and durable. I’ll update as needed.
