Male DC Power adapter - 2.1mm plug to screw terminal block

These adapters are super-handy for wiring your own power source to a DC barrel jack 2.1mm tip.

Simply secure your power source wires to the terminal block end, then plug the barrel jack side into the 'thing' you want to power (or use this breadboard barrel jack breadboard-friendly connector to use it when prototyping)

The terminal block has the polarity labelled, which assumes a centre-positive tip (most barrel jack PSUs are centre-positive, but always check first!)

We also offer a version with a female tip.
