Comparison and difference between wall-mounted and desktop power adapters?
Posted by Admin | 22 Jul
Power adapters are divided into wall-mounted power adapters and desktop power adapters. Wall-mounted power adapters are power adapters that can be directly plugged into the plug-in 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-mounted 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, and 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 are used for power supply, while computer peripherals, security products, and small home appliances generally use power adapters below 36W. Especially in today's energy conservation and environmental protection, products in this power segment are the most common. Notebooks, TVs and other products generally use power adapters below 120W, while those larger than 100W mostly use built-in power supplies. However, there are also external power adapters below 200W, but the number is relatively small. Generally, wall-mounted power adapters below 36W are mostly used. The feature of this kind of power adapter is that it does not require AC wires, which saves cost and space, and does not require countertop space for placing power supplies. It is also safer to plug directly into the plug-in board. There are a few power adapters below 36W that use desktop type. This is generally because the product used is far away from the AC plug-in board or because the power adapter is bulky, heavy, and has multiple ports. USB power adapter, in order to avoid the situation of 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-plug type, because its volume and weight are large, so the desktop type is generally used above 36W.
