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.

Consider instead
- grizzl-e-classic-connect
The same charger with Wi-Fi, about $50 more, if you actually want scheduling, usage tracking or utility demand-response. It is a D2 rather than a REJECT: United Chargers documents that it charges in 'dumb' mode with no connection, so the app is an addition rather than a dependency.
Where to buy
Open questions
- No FCC grant was found for the Wi-Fi-equipped sibling ('Grizzl-E Classic Connect') under the United Chargers grantee code either, which weakens (but does not eliminate) the sibling-control argument — the Connect model's Wi-Fi module may be certified under a chip vendor's own modular FCC ID rather than one searchable by 'United Chargers'. This does not affect the Classic's own D0 status, which rests on the manufacturer's explicit 'No Internet Connection' spec-sheet claim rather than on the sibling comparison.
- Whether the internal current-adjustment DIP switch is documented in the publicly downloadable manual or only in an installer-only supplement was not directly confirmed in this run.

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

Manufacturer's own product specification table: 'Smart function: No Internet Connection'; full spec list (type, connector, max power, plug type, protection, certifications, adjustable current, cable length, operating temperature) contains no Wi-Fi, Bluetooth, or app entry anywhere. Price observed as $299.99 USD. Also confirms UL certification (UL E510712) and Energy Star certification. — accessed 2026-09-03 - A https://fccid.io/2BOBH
FCC grantee registration for United Chargers Inc. (grantee code 2BOBH, registered 2025-03-18, Richmond Hill, Canada) shows zero FCC ID applications indexed under that grantee code — no radio-equipment grant exists for this manufacturer's product line at the time checked, consistent with the Classic containing no intentional radiator. (The sibling Wi-Fi-equipped 'Classic Connect' model was checked separately and also returned no indexed FCC ID for this grantee, so the absence is not yet confirmed as a strong sibling-control signal — see open_questions.) — accessed 2026-09-03
