United Chargers Grizzl-E Classic 40A (GR1-14-24-PB)

D0 No Radio — No radio at all. It cannot phone home.

The unplug test

Nothing changes, because there is nothing to disconnect. The Grizzl-E Classic has no Wi-Fi, no Bluetooth, and no app; the manufacturer's own spec sheet lists its 'Smart function' as 'No Internet Connection'. Current output (40A/32A/24A/16A) is set with a physical switch inside the case at install time, and the unit charges a car the same way on day one as on year ten with no vendor involved at any point after purchase.

Why this tier: The manufacturer's own product specification table lists 'Smart function: No Internet Connection' as a spec-sheet line item, and no radio (Wi-Fi, Bluetooth, or otherwise) appears anywhere in the full specifications list. Adjustable current (40A/32A/24A/16A) is set by a physical DIP switch inside the enclosure per the user manual, not an app. No FCC grant was found for United Chargers Inc. under its registered grantee code (2BOBH), consistent with a device that contains no intentional radiator.

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