Various electronic devices can be seen everywhere in people's lives, such as repeaters, laptops, game consoles, etc. In these electronic devices, a core component is the power supply, which controls the operation of the entire electronic device. It is also a small transformer that can ensure more stable voltage of the electronic device during operation and play a certain protective role in the use of the power supply. There will be some voltage labels on the power adapter.

　　In this way, people can also avoid some potential usage risks. Only when people use a power adapter can they successfully turn on the sub device to use it. The power adapter needs to be compatible with the product. In the production process of electronic products, it is the important responsibility of clerks to configure corresponding power sources, ensure correct connection with electronic products, and enable them to function normally. He is also a core component of every electronic product, capable of controlling the stability of the internal voltage of the electronic product.

　　Sometimes the manufacturers of power adapters and electronic products do not come from the same place, as many manufacturers specialize in manufacturing power adapters, but electronic products can be assigned to them before manufacturing to ensure that used power supplies and electronic products can be used and connected well. The power adapter itself has a voltage regulation function, which can not only protect the long-term use of electronic products, but also ensure that the safety factor of electronic products is improved and the occurrence of voltage instability is reduced during use. This is a qualified power supply that can be sold with more confidence at the factory.

　　Therefore, each power adapter will be labeled with some voltage and battery level. These clear standards can let people know what the voltage of electronic products is. With a power adapter, voltage regulation is flexible, the usage process is strict, and it is more reliable. Without a reasonable power supply, any electronic product cannot function properly, so the power adapter needs to be tightly integrated with the product. All electronic products use original power adapters to ensure that no malfunctions occur during use.
