The difference between plug - in and desktop power

The difference between plug - in and desktop power


      The power adapter is divided into a plug - in power adapter and a desktop power adapter, and a wall type power adapter is also known as a wall-mounted power adapter. It can be explained simply. The plug - in power adapter is the power adapter that the body can plug directly into the plugboard. The desktop power adapter is the power adapter that the ontology needs to be placed on the desktop. The difference between a desktop power adapter and a plug - in power adapter is that a desktop power adapter requires AC lines to connect to the city.

     Power adapter in security products, communication products, as well as small home appliance products and is widely used in consumer electronic products, especially in portable consumer electronics and communications products, generally in the majority with less than 10 w, such as smart phones and tablets generally adopts 5-10 w power adapter power supply, and computer peripheral, security products, small home appliances products generally adopt the following 36 w power adapter in the majority, especially in today's energy advocate energy conservation and environmental protection, the power of products is the most common. And laptop, TV and other products generally use the power adapter below 120W, and more than 100W use built-in power. But there are also 200W with external power adapter. But the Numbers are relatively small.

     Commonly used more plugged into a wall under 36 w power adapter, the characteristics of the power adapter is not to need to AC wire, so relatively save cost, save space, do not need to be placed the mesa power cargo space. It is also safer to plug directly into the board. There are a few below 36 w power adapter using the desktop type, the general because of considering the use the product from the AC plug plate distance far away or because the power adapter volume is larger, quality is heavier, or power adapter on the heavier. For example, multi-port USB power adapter, in order to avoid the use of the above plug in the USB products more and lead to instability. The power adapter that is greater than 36W is not suitable to be inserted into the wall type, because its volume and weight are larger, so more than 36W generally adopts the desktop type.

     And in the early days we had a lot of contact with linear power. For example, the repeater used in the last century. The unit is bulky and bulky. There may also be awkward situations that fall off the plugboard directly because of the instability. But with the development of science and technology, as well as to the increasingly tense energy, the requirements for energy efficiency is higher and higher, consumer electronics products for the power adapter is high efficiency, wide input voltage range of requirements, as well as copper, iron, and the increase of labor costs, the linear transformer were gradually replaced by the switching power adapter.
