Who this is for

It is a sensible fit for keeping a spare where you need one and replacing a worn cable.

Some context

Cables are not interchangeable. Power delivery and data rate vary widely between cables that look identical, and the difference only shows up under load. Against the other 209 cables we list, this one sits around the middle of the range at R479, with most falling between R89 and R4 116.

Worth checking

• Length is worth thinking about before ordering — a cable that is slightly too short is useless.
• Check the exact model and variant against what you own before ordering, as compatibility is usually model-specific.
• Read the specification rather than the headline — the number in the title is rarely the one that decides the fit.
• If you are unsure whether this suits your setup, ask us before ordering rather than after.
• Confirm the variant matches the one you need; near-identical model codes often differ in one specification that matters.
