AC Power Adapter

 

AC power adapters are external power supplies for portable computers such as laptops and tablets. As the name suggests, they convert AC power from the mains supply to a stable DC power that the computers require. Each Ac adapter has an output power rating depending on the device it is intended for. An external power supply has made it possible to design slimmer and more portable PCs. When buying a new AC adapter, you need to consider its efficiency. Just as a reminder, this is the ratio of output power and input power. An efficient AC adapter reduces power wastage and generates less heat, a characteristic of almost all AC adapters. They depend 100% on the natural flow of air for cooling because of the less heat generated.
