Spectra Baby USA S1 Plus Rechargeable Double Electric Breast Pump
D0 No Radio — No radio at all. It cannot phone home.
The unplug test
There is nothing to unplug except the pump itself. It runs on physical buttons and an internal rechargeable battery, remembers your last session's settings on its own, and shuts off automatically after 30 minutes with no phone, app, or account involved at any point. It has behaved identically since the day it was made and always will.
Why this tier: Both the manufacturer's own product page and its own setup/operation instructions describe the S1 Plus entirely in terms of physical buttons, a digital display, and a rechargeable battery, with no mention of WiFi, Bluetooth, an app, or an account anywhere. No radio is claimed by the manufacturer or found by any reviewer. No intentional radiator, no vendor cloud: D0.

Open questions
- An FCC lookup was not completed for this device specifically (only a secondary, un-cited search snippet claimed a Part 15B unintentional-radiator compliance statement, which was not independently verified against a primary source and so is not used to support this record). This does not change the tier — no vendor markets any connectivity for this pump and both manufacturer sources describe pure physical controls — but a direct FCC/label check would tighten the record.
- Price band left unknown per project policy on search budget.

Class A is primary (manual, FCC filing, teardown). Class B is corroborated community reporting. Class C is never sufficient alone.
