5v Wall Mount Adapter

What does the current and voltage marked by the power adapter mean
First, the nominal voltage of the 5v wall plug in adapter refers to the voltage output by the power supply, that is, the voltage when the power supply is not connected to any load, so it can be understood as the upper limit of the power supply voltage.
The nominal current of the power supply is due to the internal resistance inside the power supply. When the current flows through the power adapter, a voltage drop occurs in the power adapter, causing the power adapter to generate heat, the power supply generates heat, and the output voltage decreases.
