Plug-in adaptors are a type of electrical accessory that allows users to connect their devices to different power sources. These adaptors are designed to fit into various types of outlets, converting the outlet to a compatible plug type for the device.
They are useful for travellers, as different countries often have different types of electrical outlets. Adaptors are also commonly used to expand the number of outlets available in a single location, allowing users to plug in multiple devices simultaneously. They come in a variety of shapes and sizes, making them versatile and easy to use for a wide range of electrical devices.
