A key point was:
⚡ Key Charger Parameters Explained
1. 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.
