AC DC Desktop, Wall Adapters are a category of power supplies designed to convert alternating current (AC) from a wall outlet into direct current (DC) that can be used to power or charge electronic devices. These adapters are external to the devices they power and often come in two main designs: desktop versions, which sit on a surface and usually have a separate power cord that plugs into the wall socket, and wall adapters, which plug directly into the outlet and dangle from the socket or lay flush against the wall. The main function of these adapters is to provide a safe and reliable power source for devices such as laptops, smartphones, game consoles, and other household electronics, ensuring compatibility with the electrical grid and the specific voltage and current requirements of the device.
These power adapters are valued for their convenience and versatility, with most featuring varying voltage outputs and interchangeable tips to fit different electronic devices. Some are specifically designed with universal input voltage compatibility, making them ideal for international travel. The main characteristics that distinguish these products include their energy efficiency ratings, output power levels, physical size, and the presence of additional features like USB charging ports. Prominent manufacturers in this field include big names like Delta Electronics, Bel Power Solutions, Mean Well, and Phihong, among others.
