How much power does the charger consume?

In fact, the power consumption of a single charger is not large. The communication industry standard of the People's Republic of China yd-t1591-2009 "Technical requirements and test methods for power adapters and charging/data interfaces for mobile communication terminals" states that the rated output current of the power adapter should be in the range of 500 mA to 1500 mA. , determined by the manufacturer. The power consumption is less than 150 milliwatts at no load energy consumption of the power adapter. The regular chargers we use will meet the relevant national standards. But as mentioned above, if most of the user's chargers are left on the power supply, the accumulated power consumption is still very shocking.
