The more generous the cross-section, the less voltage is lost on the way and the more stable the supply stays when the device briefly draws more. At 2 × 2 mm², that's ample for a DC cable; the brown fabric sleeve keeps everything flexible and tidy.\u003c\/p\u003e\u003ch2\u003eWhat you get\u003c\/h2\u003e\u003cp\u003eThe right connector combination – and with it the part where all the effort otherwise gets stuck. A high-quality linear power supply connected via the bundled lead is like a good wine in a toothbrush cup.

If yours takes 2.5 mm on both ends, Version 1 is the right one. The difference is tiny, but it decides whether the connector holds or wobbles.

Alternatively, measure the inner pin of the existing socket. If you're unsure, tell us your device and power supply – we'll tell you which version fits.\u003c\/p\u003e\u003ch3\u003eWhat happens if the connector doesn't fit exactly?\u003c\/h3\u003e\u003cp\u003eAn inner diameter that's too large sits loose, contact becomes unreliable and can drop out in operation. One that's too small won't fit at all.
