Well, not quite. Both chargers and devices need not support all charging standards/profiles and thus may disagree on working together. A working (all USB PD profiles up to 100W supporting) charger looks inherently the same as a profile-1 only one, and both may even say "USB PD" in the specs. Thank god the MacBook accepts the widespread 5V/3A USB-PD power level and even USB BC.
