These 2.1mm barrel plugs come with a tapped plastic torus to protect them from some of the elements.
They’re perfect for repairing your laptop’s power supply without getting stopped by the TSA for having “modified electronics”, though knowing you, they’ll get you for something else. To use, simply drop the plastic torus over your wires small-hole first, solder a wire into the pin in the center and another through the hole in the sheath. We recommend center-positive, but you can do whatever you like as long as you don’t plug a non-center-positive jack into any of our equipment.
