Can someone tell me what the difference in the watt numbers on the chargers is? How does it affect the charging?

Doing a Google search for 'what do watt numbers mean on chargers' this site popped up:

A key point was: Key Charger Parameters Explained1. Wattage (W): Total Power Output·Formula: Voltage (V) × Current (A) = Wattage (W)·A 20W charger = 5V × 4A or 9V × 2.2A depending on configuration.·Higher wattage = faster charging (if the device supports it).
Note: Higher wattage=faster charging, IF THE DEVICE SUPPORTS IT.
