The difference between power adapter and voltage regulator

The power adapter is a kind of electronic device that we usually use more commonly. Its main function is to convert 22V household electricity into DC power suitable for mobile phones, tablets, notebooks, smart cameras, routers, set-top boxes and other equipment. Then it and the voltage regulator What is the difference between the differences, the following is a brief introduction for you.
The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into AC output type and DC output type. Straightforwardly, it can be understood as a voltage converter, such as converting 110-220 volts of AC voltage into a fixed DC voltage. It is mainly divided into wall-mounted chargers and desktop chargers. Wall-mounted power supplies are used for mobile phones, tablets, routers, and cameras, and desktop power supplies are used for notebooks, electric vehicles, and balance cars.
A voltage regulator is a device that stabilizes the output voltage. The voltage stabilizer is composed of a constant voltage regulator, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator. By automatically adjusting the coil turns ratio, the output voltage is kept stable.
