DC Power Jack Male Plug – DC Barrel Connector for Power Cable Repair & DIY Wiring

A DC power jack male (male barrel plug) is a basic but essential connector used to deliver DC power from an adapter or power supply to compatible devices. It’s commonly used for cable repair, DIY wiring, and custom power leads where you need a standard-style DC plug on the end of a cable.
