5.5 / 2.1mm Barrel Connector - DC Power Plug

DIY? How about D-I-Wire! This barrel jack plug is great for adding a common power connector to the end of your wires. The jack is compatible with 5.5mm barrel jacks that have a 2.1mm center pole diameter. The outer shell unscrews to reveal solder terminals and a crimp strain relief. Nifty, tidy, and practical.
