AC AC Wall AdaptersAC AC wall adapters, also known as AC/AC wall adapters or power converters, are devices that convert AC power from a wall outlet into a different AC voltage or frequency. These adapters are commonly used to power electronic devices that require a specific AC voltage or frequency that is different from the local AC power supply. AC AC wall adapters typically include a transformer and rectifier circuit to convert the AC power, and may also include features such as protection circuits and user-adjustable output voltage. They are commonly used in a variety of applications, including consumer electronics, industrial equipment, and portable devices.
