Power adapter is a small portable electronic equipment and electronic electrical power supply conversion equipment, generally by the shell transformer,  

Inductor, capacitor, control IC, PCB board and other components, its working principle has AC input into DC input, connection can also be divided into wall type and desktop type,  

Widely used in security cameras, set-top boxes, routers and other devices."  

Rated power is the output power of the power supply at rated voltage.  

Maximum power is the maximum output power a power supply can withstand.  Also called peak power.  

Actual power is the actual work of the power supply.  

It is mainly the current that causes the change in power.  The voltages are fixed at 5V and 12V, and each power loop has its own rated operating current.  Under normal circumstances, the actual operating current is always less than the rated operating current,  

After a high-power component is added or replaced, the actual working current may exceed the rated power supply current and the power supply may be overloaded.  

Long-term overheating of power supply will lead to long-term heating aging of components, which further affects the reduction of rated power and reduces the service life of power supply.  For a power supply without a protection loop, this can cause the power supply to burn.
