USB-C charging-only cable class

A USB-C cable with a high power rating can still carry USB 2.0 data; a power label alone does not mean “charging-only”.

Capability ledger

Six questions kept separate

DataConditional

A power-rated USB-C cable can still carry USB 2.0; charging label does not prove no data.

Evidence: C046A

Power / chargingDocumented

Power marking is a separate evidence field from data capability.

Evidence: C046A

VideoUnknown

Video support is not established by a power label.

ConversionNone

No conversion function is represented.

Length / reachNot Established

No class-wide length claim asserted.

Markings / certificationDocumented

USB-IF power/data markings must be interpreted separately.

Evidence: C046A

Explicit unknowns

Charging-only cannot be inferred from a high power label alone.

USB-IF’s January 2026 cable-logo guidance separates power and data markings. USB 2 C-to-C cables use power marking without a required data-rate number; that omission is not evidence of no data support.

Scope: Present USB-IF compliance and logo guidance for USB Type-C-to-Type-C cables; not a retrospective classification of every legacy cable. · review due 2027-01-06

USB 2.0 data capability is distinct from 60 W / 240 W power labeling.

Common questions

Questions this record can help resolve

Why does a USB-C cable charge but not carry a display?Treat charging and display transport as separate capabilities instead of assuming one successful USB-C function proves every other function.Are all USB-C cables the same for charging?Keep the connector form separate from cable-specific charging/current evidence and the exact devices participating in power negotiation.How do USB-C cable power and data markings differ?Read watts and data rates independently; a power-only USB 2 marking is not a no-data verdict.
