Two USB-C ports can look identical and still deliver very different charging performance.
When I review a residential wall socket with USB-C, I never treat “Type-C” as the power specification.
USB-C describes the interface. The charging experience comes from the architecture behind it: source capability, PD controller and firmware, supported power profiles, cable and device negotiation, thermal design, and the power-sharing rule when more than one port is in use.
That distinction matters in OEM/ODM development because a clean front face can hide very different engineering decisions.
Before tooling or label approval, I want the brand team to lock the target device mix, single-port behavior, simultaneous-port behavior, protocol requirements, thermal limits, protection strategy and the claims that will appear on the product and packaging.
Leave those decisions too late, and you can end up with the right connector but the wrong charging experience.
For me, USB-C is the starting point of the specification — not the specification itself.
