GP's point is that although chargers are labeled with wattage, they can't output any combination of volts and currents as long as they multiply to the stated wattage. Can you take a normal 100W charger and ask it to output 100V and 1A? It can't.
The Apple 29W charger supports two configurations only: 14.5V × 2A, or 5.2V × 2.4A
The Apple 30W charger supports these four instead: 20V × 1.5A, 15V × 2A, 9V × 3A, 5V × 3A

Do you see a problem here?
