Spectra S1 Plus Output Test: Real Milk Volume and Cycle Settings Compared
By James H. Sterling
Pumping parents face an immediate decision when examining health insurance benefits formularies: pay an upgrade fee for the blue S1 or accept the pink S2 at zero out-of-pocket cost. Both machines share identical internal pump mechanisms, circuit boards, and suction capabilities.
| Technical Feature | Spectra S1 Plus | Spectra S2 Plus |
|---|---|---|
| Chassis Housing Color | Soft Blue / White | Soft Pink / White |
| Power Architecture | Internal Rechargeable Li-Ion (11.1V, 2000mAh) | A/C Wall Adapter Only (12V Input) |
| Real-World Run Time | **150, 180 minutes** continuous | 0 minutes untethered |
| Average Insurance Upgrade Upcharge | **$50, $95** copay | **$0** fully covered under ACA |
| Weight Profile | 3.3 lbs (1.5 kg) | 2.9 lbs (1.3 kg) |
The S1 houses an 11.1-volt lithium-ion cell that delivers untethered freedom around living spaces. Parents can pump at a kitchen island, relocate across a nursery, or express during cross-town commutes without hunting for electrical outlets. For mothers managing twins or return-to-office timelines, those cordless minutes justify the out-of-pocket upgrade surcharge. Those establishing a stationary nursing desk setup can save capital by taking the zero-dollar S2 and routing cords through desktop cable trays.
