USB-C hosts and power adapters are only allowed to provide 5V if they can sense a downstream device (either via a network of resistors or via explicit PD negotiation). Out-of-spec USB-C devices sometimes skip that, and out-of-spec USB-C chargers often (somewhat dangerously) always supply 5V, so the two mistakes sort of cancel out. |
