What is an adapter
An adapter is an interface converter that can be an independent hardware interface device that allows hardware or electronic interfaces to be connected to other hardware or electronic interfaces. It can also be an information interface, such as a power adapter, tripod base adapter, USB and serial port adapter device, etc.

Basic meaning of adapter
In computers, adapters are usually built into cards that can be inserted into slots on the motherboard (there are also external ones), and the adapter information in the card is exchanged between the processor and the devices supported by the adapter.
A power adapter is a power conversion device for small portable electronic devices and electronic appliances. It generally consists of a housing, a power transformer, and a rectifier circuit. According to its output type, it can be divided into AC output type and DC output type; According to the connection method, it can be divided into wall mounted and desktop mounted. Due to the lack of batteries, power adapters are particularly important for mobile PCs.
Most mobile PC power adapters can automatically detect 100-240V AC power (50/60Hz). Basically, all mobile PCs have an external power supply connected to the host via a single cable, which can reduce the size and weight of the host. Only a very small number of models have a power supply built into the host. There is a nameplate on the power adapter, which indicates indicators such as power, input and output voltage, and current. It is particularly important to pay attention to the range of input voltage, which is called a "travel power adapter".
