Eufy S1 Pro Review
I’ve tested a lot of wearable pumps, and when I saw the Eufy S1 Pro hit the market, I knew I had to try it. It retails around $349, which puts it in line with most premium wearable pumps—but does it live up to the hype?
Here’s my honest review after using it for a bit, including what I love, what I don’t, and whether I think it’s worth the investment.

A Quick PSA: Wearables Shouldn’t Be Your Primary Pump
I don’t recommend using any wearable pump as your primary or only pump—especially in the early days of establishing supply.
Here’s why:
Wearables often aren’t as strong or efficient as traditional pumps.
They often require double the amount of time to make you feel “empty”
They’re amazing for convenience—but that can come at the cost of milk removal over time.
If you’re trying to maintain or build supply, your main pump should be something a little more powerful.
Think of wearables like this: They’re supplements, not replacements. Great for errands, work, or chasing toddlers—but not the tool you want to rely on 100%.
The Charging Case: My Favorite Feature
Let’s start with the thing that immediately had me in a chokehold—the charging case. It’s sleek, compact, and makes this pump feel travel- and work-friendly in a way that most other wearables just don’t.
It’s not totally necessary if you’re pumping mostly at home.
But for work, errands, or travel? It’s a game-changer.
The case takes 3.5–5 hours to fully charge, depending on whether the motors are in and connected.
It’s noticeably less bulky than any of my other wearable pump cases.
This feature alone makes me reach for the Eufy more often than I expected.
Heat Flow Technology: A Nice Bonus
The S1 Pro includes heat flow technology, which isn’t essential but can help stimulate milk flow, especially for moms who notice a difference with warmth.
If you use the fridge hack (reusing pump parts between sessions by storing them in a sealed container in the fridge), this warmth might be especially welcome. It’s not a must-have for everyone, but it does feel nice.
Customization via the App
The Eufy app makes this pump super customizable:
Set your session duration and heating time
Choose your rhythm: Max, Standard, Gentle, or Natural
Each rhythm has its own preset setting, but you can still switch between expression and stimulation modes as you wish
It’s nice to have this level of control, especially if you’re picky about suction settings. That said, if you’re not comfortable with Bluetooth tech on your chest, that’s something to consider.
Pump Design Details
Cups hold 5 oz—a decent size for most sessions
No overflow sensor, so you’ll need to keep an eye on your output manually
Silicone flanges which some people prefer
Shorter flange tunnel is something to be aware of if you have elastic tissue - however because of where the diaphragm is at the end of the flange tunnel (also made of a soft silicone), it shouldn’t cause discomfort if your nipple reaches the whole way to the end and touches the diaphragm.
The pump stands upright when not in use—minor, but helpful!
It’s not super loud, which is a nice perk if you’re pumping around others
Output & Overall Experience
Let’s talk results: I get consistently decent output with this pump. For a wearable, it has decent suction strength and definitely holds its own.
I find myself reaching for this pump often, mainly because:
The charging case is so easy to toss in a diaper bag
It’s comfortable enough (for a wearable)
Now—do most wearables feel a little pinchy to me? Yes. That’s just how they feel on my body, and while it doesn’t stop me from using them, it’s something I always notice. So if you're super sensitive, just know that wearables in general might not be your favorite.
Final Thoughts: Is It Worth It?
If you’re someone who pumps on the go, works outside the home, or just wants a sleek, customizable wearable that doesn’t take up half your kitchen counter—the Eufy S1 Pro is a really solid option.
It’s not perfect, and it doesn’t have all the bells and whistles (like an overflow sensor), but it delivers a good pumping experience, great portability, and solid output.
That said, a couple things to keep in mind:
Wearables shouldn’t be your primary pump. They’re amazing for convenience—but in general, they don’t remove milk as effectively as a traditional or hospital-grade pump. I recommend using a wearable like this as a backup or on-the-go option, not your main one—especially in the early weeks when you’re still building supply.
You can save money by skipping extras. The charging case and heat flow technology are optional add-ons. If you don’t need heat or don’t plan to pump away from home often, you can purchase just the base pump and save a decent chunk of change.
All in all, the Eufy S1 Pro is one of the better wearables I’ve tried—and if you’re clear on what you need it for, it can definitely earn a spot in your pump lineup. Get it on Amazon!
