What Is the Charging Power of Wall-Mounted Charger?

Input: 100-240v 50/60Hz 0.2A Output: 5.0V 550mA Input is 100× 0.2 = 20W. Why 100 is used? It is because the parameter is in the limit case. If 240 is used, there is no current of 0.2A. Output power is 5× 0.55 = 2.75 watts. Only in the charging state. If there is no current without charging, there will be no output power. Note: The input power can only be reached when the charger is fully loaded, that is, if you are charging at 5.0V 550mA, the power consumption is 20 watts. If you don't charge, or the charge is almost full and the current is small, the power will be small and can be ignored. If you don't believe me, you can look at your electricity meter. The electricity meter won't turn under the condition of low current charge or full charge.
