The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of components such as a casing, a transformer, an inductor, a capacitor, a control IC, a PCB board, etc. Its working principle is converted from an AC input to a DC output; The way can be divided into wall-mounted and desktop. Widely used in security cameras, set-top boxes, routers, light bars, massage instruments and other equipment.
The power adapter is also called an external power supply. It is a power supply voltage conversion device for small portable electronic devices and electronic appliances. It is commonly found in small electronic products such as mobile phones, liquid crystal displays and notebook computers.
Most notebook power adapters are suitable for 100 to 240V AC (50/60Hz). Basically, most laptops have external power supplies and are connected to the main unit with a power cord. This reduces the size and weight of the mainframe. Only a very small number of models have built-in power in the mainframe.
There is a nameplate on the power adapter, which indicates the power, input and output voltage and current quantity, etc., pay special attention to the range of input voltage. This is the so-called "travel power adapter", if the country has a voltage of only 110V. This feature is very useful, some parallel laptops are only sold in the country of origin, without this compatible voltage design, even a single input voltage of 110V, will be burned when plugged in China's 220V mains voltage.
