AC adapter dc 12v 1000ma

The power wall plug adapter is a power conversion device for small portable electronic equipment 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; it can be divided according to the connection method. It is wall-mounted and desktop type. Since mobile PCs do not have batteries, the power wall plug adapter is particularly important for them.

The power wall plug adapter of most mobile PCs can automatically detect 100-240V AC (50/60Hz). Basically all mobile PCs have an external power supply and connect to the host with a cable, which can reduce the size and weight of the host. Only a few models have the power built in the host.　There is a nameplate on the power wall plug adapter, which indicates the power, input and output voltage and current and other indicators. Pay special attention to the input voltage range. This is the so-called "travel power wall plug adapter".
In a computer, the wall plug adapter is usually built into a card that can be inserted into a slot on the motherboard (there are also external ones), and the adapter information in the card is exchanged with the processor and the device supported by the wall plug adapter.

The wall plug adapter is an interface converter, which can be an independent hardware interface device, allowing the hardware or electronic interface to be connected to other hardware or electronic interfaces, or it can be an information interface. For example: power wall plug adapters, tripod base adapter parts, USB and serial port adapters, etc.
