🔬 Key Features That Matter
🏥 Hospital-Grade Motor
The same suction strength as hospital pumps (up to 350 mmHg). This matters because weak pumps don't empty breasts fully, which can decrease supply.
Our experience: Output matched hospital pump within 0.5 oz per session.
🔋 Rechargeable Battery (S1)
~3 hours of pumping per charge. You can pump during power outages, road trips, or anywhere without an outlet.
Our experience: Pumped in the car, at parks, during family gatherings. Freedom.
⚙️ Adjustable Settings
Independent suction (1-12) and cycle speed (38-54 cpm) controls. Plus "let-down" mode button for massage phase.
Our experience: Found my perfect setting: Cycle 3, Suction 7. Every body is different.
🔒 Closed System
Milk never contacts the motor or tubing. More hygienic, easier to clean, and pump can be safely used for multiple babies.
Our experience: Planning to use for baby #2. Medela open systems can't do this.
👩 Mom's Pumping Journey
"I exclusively pumped for 12 months. Not by choice—my daughter had a tongue tie that made direct nursing painful. That meant 6-8 pumping sessions a day, every day, for a year. The pump you choose MATTERS.
Week 1 (hospital Medela Symphony): Established supply beautifully. 4oz per side per session by day 5.
Week 2-4 (cheap insurance pump): Supply started dropping. Sessions took 30+ minutes. Nipple pain increased. I was ready to quit.
Month 2+ (Spectra S1): Everything changed. The hospital-grade suction matched what I'd used in the hospital. My supply rebounded within a week. Sessions dropped to 15-20 minutes. I could finally pump without dreading it.
The settings that worked for me:The battery was life-changing. I pumped during my commute, at the park while my toddler played, during power outages. That freedom made the difference between quitting at 6 months and making it to 12.
- Let-down mode: 2 minutes to trigger milk flow
- Expression: Cycle 3, Suction 7
- Higher suction isn't always better—find your sweet spot
What I'd do differently: Get properly sized flanges immediately. I struggled for weeks with the standard 24mm before discovering I needed 19mm. Game-changer for comfort and output."

🔄 Spectra S1 vs S2 vs Medela
💡 Our recommendation: S1 is worth the extra $40 for the battery alone. Unless you'll ONLY pump at home with reliable power, get the S1.
❓ Frequently Asked Questions
Is Spectra S1 covered by insurance?
Yes, Spectra S1 is covered by most insurance plans under the Affordable Care Act. Use a DME supplier like Aeroflow, Edgepark, or The Breastfeeding Shop who handle insurance billing directly. You may pay nothing out of pocket.
What flange size do I need?
The Spectra S1 comes with 24mm and 28mm flanges. Most women need 19-21mm. Measure your nipple diameter (not areola) and add 2-3mm. Signs of wrong size: pain, rubbing, white marks, or poor output. Correctly sized flanges make a HUGE difference.
How long does the S1 battery last?
About 3 hours of active pumping (roughly 6-9 sessions). Charges in 2-3 hours. You can pump while charging. We recommend charging nightly.
Can I use Medela parts with Spectra?
Not directly—different threading. But adapters exist (Maymom, Nenesupply) that let you use Medela flanges and bottles. Useful if you have Medela parts already.
🏆 Our Final Verdict
The Best Pump for Serious Pumping
After 12 months and 1,000+ sessions, the Spectra S1 earned its reputation as the gold standard for personal breast pumps. Hospital-grade suction, customizable settings, and the rechargeable battery combine to make exclusive pumping actually sustainable.
It's not a wearable pump—if you need truly hands-free, look at Elvie or Willow. But for output, comfort, and value, nothing beats the Spectra S1. Get it through insurance if you can; you've already paid for it through your premiums.
