The power adapter is divided into wall-plug type and desktop type. Wall-plug type is also called wall-mounted power adapter. This may not be clear to everyone. Let’s follow the editor to learn about it together!
Wall-type power adapter is the power adapter that the body can be directly plugged into the board. The desktop power adapter is the power adapter that the body needs to be placed on the desktop.
The difference between the desktop power adapter and the wall plug-in power adapter is that the desktop power adapter needs an AC cable to be connected to the mains.
Power adapters are widely used in security products, communication products, as well as small household appliances and consumer electronics products, especially in portable consumer electronics and communication products, which are generally less than 10W.
For example, smart phones and tablet computers generally use 5-10W power adapters for power supply, while computer peripherals, security products, and small home appliances generally use power adapters below 36W. common. While notebooks,
TVs and other products generally use power adapters below 120W, while those larger than 100W mostly use built-in power supplies. But there are also external power adapters below 200W. But the number is relatively small.
Generally below 36W, plug-in power adapters are mostly used. The feature of this power adapter is that it does not require AC wires, which saves cost and space, and does not require the countertop space for placing the power supply. It is directly plugged into the plugboard. Safety.
There are a few power adapters below 36W that are desktop type, which is generally because the product is far away from the AC socket or because the power adapter is large and heavy, or the power adapter is heavy.
For example, a multi-port USB power adapter, in order to avoid the unstable insertion caused by the use of many USB products plugged on it. And the power adapter larger than 36W is not suitable for wall-plugging. Because of its large size and weight.
Therefore, the desktop type is generally used above 36W.
