Male DC Power adapter - 2.1mm plug to screw terminal

The Male DC Power Adapter 2.1mm Plug to Screw Terminal is a simple and practical power conversion accessory designed for electronics and prototyping applications. It allows users to easily connect a wired power source or battery pack to devices that use a standard 2.1mm DC barrel jack input.

One side of the adapter features a 2.1mm male DC plug, while the other side provides a screw terminal block, enabling secure and tool-free wire connections. The terminals are clearly marked for positive (+) and negative (-) polarity, supporting the most common center-positive DC power configuration.

This adapter is widely used in DIY electronics, embedded systems, LED installations, and security systems where quick and reliable power distribution is required without soldering.
