Magnetic USB-C cables sit outside the USB Type-C specification, and the most common complaint from long-term users is not fire but a tip that stops charging reliably after a few months, sometimes showing a charging icon while the battery drains. This guide explains where the risks come from (live disconnects, exposed pins, contact wear), what design choices reduce them, and how pin count decides what a magnetic cable can do: 1-pin tips charge only, 9-pin and 16-pin lines reach 240W, and only 24-pin adapters carry 40 to 80Gbps data and external video. It closes with GREENPORT's 9-pin, 16-pin and 24-pin magnetic lines and a checklist for testing samples yourself.

It also explains the color and length checkbox system that lets one printed box cover a whole model family.
