Background

Accessories are worth matching precisely to the device you own. Most returns in this category come down to a compatibility detail rather than quality. Against the other 1268 accessories we list, this one sits towards the affordable end of the range at R269, with most falling between R269 and R19 133.

Points to check

• Check the exact model and variant against what you own before ordering, as compatibility is usually model-specific.
• Look at the specification you will still care about in two years, not only the one that matters this week.
• Check what is included in the box, as bundled cables and adapters vary between models and regions.
• Confirm the variant matches the one you need; near-identical model codes often differ in one specification that matters.
• Read the specification rather than the headline — the number in the title is rarely the one that decides the fit.
