Warmth and massage in a wearable, no case to carry
The eufy Wearable Breast Pump S2 massages, warms and pumps at once from two cups inside your bra. It’s the same pump as the eufy S2 Pro, without the charging case, so it suits moms who pump near a charger.
Charge it on the magnetic cable, and eufy rates one charge at about 6.5 hours of pumping.
Is the eufy S2 right for you?
Best for
- Pumping at home or at a desk, where a charger is close by
- Moms who want massage and warmth in a wearable
- Keeping the pump bag light: two cups and a cable

Maybe not for
- Long days away from an outlet. The eufy S2 Pro is the same pump with a case that recharges it on the go.

Questions moms ask about the eufy S2
How strong is the eufy S2 suction?
Up to 300 mmHg across 10 expression levels (7 in stimulation mode) and 3 speeds, eufy says. That is a higher maximum than the Spectra S1 and S2, which list 270 mmHg. Compare maximums only; a higher number does not mean a pump empties better.
How do you assemble the eufy S2?
Assembly takes six steps, from eufy’s user guide. 1. Press the duckbill valve into the small hole inside the container and flick it to check it holds. 2. Fit the container back (lid on the top slot, tab into the container slot), press the top and then the bottom until it clicks, with all 4 alignment marks above it, and press the lid into the spout. 3. Seat the dry diaphragm in its recess. 4. Line up the peg on the pump hub with the diaphragm hole and press the container onto the hub until it clicks. 5. Press the flange on. 6. Pick an insert with the Nipple Measurement Card and set it in the flange tunnel.
How do you clean the eufy S2?
Rinse every washable part in warm, soapy water and let it air dry; the pump hub is not washable, so wipe it with a dry cloth. Before first use, eufy says to boil the parts for up to 5 minutes, stirring constantly, or steam them, and never to sanitize in a microwave. Use only the supplied brush on the duckbill valve. eufy’s guide does not say whether the parts are dishwasher safe.
What parts does the eufy S2 have, and when do they need replacing?
eufy counts 5 parts to wash on each pump. The guide names the milk container, container lid and back, duckbill valve, diaphragm and its lid, and the flange; the pump hub is not washable. eufy rates the washable parts at 1 to 3 months and says to replace them sooner if suction drops, especially the duckbill valve. Replacements are sold at eufy.com.
What flange size does the eufy S2 use?
A 24 mm double-sealed flange, plus 15, 17, 19 and 21 mm sizing inserts in the box. Measure with the Nipple Measurement Card, set the closest insert in the flange tunnel, and try another size if output drops or it hurts, eufy says.
How long does the battery last?
About 6.5 hours of pumping per charge, eufy says, from a 1460 mAh battery in each pump. A full recharge takes about 1.7 hours on the magnetic cable, and the pump will not run while it charges.
How much milk does each cup hold?
5 oz per cup, with larger 7 oz containers sold separately, eufy says.
What’s the difference between the eufy S2 and S2 Pro?
The pump is the same. The eufy S2 Pro adds a wireless charging case that holds and recharges both pumps, plus a stain-proof mat. The S2 charges with a magnetic cable and includes flange dust covers.
How loud is the eufy S2?
Under 46 dB, eufy says, the same rating it gives the S2, S1 and S1 Pro.
Is the eufy S2 hospital grade?
eufy publishes 300 mmHg as the maximum suction, and we do not call it hospital grade. We describe it by that published number instead.
Can I use the eufy S2 lying down?
eufy’s guide says not to lean back or bend forward excessively while pumping, because it can cause leaks. Lean slightly forward when you put the pumps on, so your nipple sits centered in the flange tunnel, and wear a full-coverage nursing bra with a flap.
Does insurance cover the eufy S2?
Most health plans must cover a breast pump under federal rules, and we check whether yours covers the eufy S2. Start your order through insurance, and we will tell you before anything ships if your plan covers a different pump.
Can I get a eufy pump through insurance?
Most health plans, including Marketplace plans, must cover a breast pump under federal rules (HealthCare.gov). We check your plan, get the prescription from your doctor, and ship the S2 to your door. If your plan covers a different pump, we will tell you before anything ships.
