How To Distinguish Chargers And Power Adapters?

A charger is used to charge a device with a power supply, usually with a charging indicator light, such as a battery car charger and a mobile phone charger. The power adapter is a device that directly provides electrical energy to electrical appliances, such as an adapter for a liquid crystal display, so why are these two names confused? Let’s also talk about switching power supply. Switching power supply is a method of turning 220V voltage into low-voltage direct current, which is different from traditional power frequency transformers. The power supply using this switching voltage conversion technology is called a switching power supply. In our daily life, whether it is a charger or a power adapter, it converts 220V household electricity into low-voltage direct current suitable for electrical equipment, and its functions are similar.
So some people will call the charger of the iPhone 12 an adapter. In fact, they are all the same and have similar meanings, but the name of the charger is to focus on its purpose, and the name of the adapter is to highlight the auxiliary function of the main equipment. My analogy: The charger is equivalent to the rice bowl, and the adapter is equivalent to the tableware.
