AC DC Desktop, Wall AdaptersAC/DC desktop and wall adapters are types of external power supplies that are used to convert alternating current (AC) power from a wall outlet or other source into direct current (DC) power that can be used by electronic devices. These adapters are often small and portable, and are designed to be plugged into a wall outlet or other AC power source. AC/DC desktop and wall adapters are commonly used to power a wide range of electronic devices, including laptops, tablets, smartphones, and other portable devices. In some cases, the adapter may include additional features such as voltage and current regulation, protection against over-voltage or over-current conditions, and indicator lights to show the status of the power supply. Some AC/DC desktop and wall adapters are designed to be universal, and can be used with a variety of different devices, while others are designed for use with specific devices and may include custom connectors or other features.
