Can charging on PD USB-C wall charger damage your USB-C hardware?

The manufacturer of the Kinesis keyboard suggests only charging the keyboard via USB-C ports and hubs from computer and never from wall chargers. Can some devices like my Kinesis keyboard really be damaged if charged using my Anker USB-C GaN charging adapter instead of the USB-C port from my computer?
