Unless the other end lies about what voltage they're getting, a cable can't lie about its ability to carry current.

Cheap cable maker can just program cable to pretend to be more powerful one but not have wiring up to spec: > Sources Shall detect the type of Attached cable and limit the Capabilities they offer based on the current carrying capability of the cable determined by the Cable capabilities determined using the Discover Identity Command (see Section 6.4.4.2) sent using SOP’ Communication (see Section 2.5) to the Cable Plug. The Cable VDO returned as part of the Discover Identity Command details the maximum current and voltage values that Shall be negotiated for a given cable as part of an Explicit Contract. Please don't talk about stuff you have no idea about.
