What is a charger and what is a power adapter?
1: Charger usually refers to a device that converts alternating current to low-voltage direct current.
It contains current limiting, voltage limiting and other control circuits to meet charging characteristics.
The power adapter is a power converter after transformer, rectifier and voltage regulator. The output is DC,
which can be understood as a low voltage regulator in the case of power.
2: power adapter is a small portable electronic equipment and electronic electrical power supply conversion equipment,
it puts the power external, with a line and the host connection,
This reduces the size and weight of the mainframe, and very few devices and appliances have power supplies built into the mainframe.
It consists of a power transformer and a rectifier circuit,
According to its output type can be divided into AC output type and DC output type; According to the connection mode,
it can be divided into wall type and desktop type.
