E-Marker Chip (Shopping)

Buying & Quality

The electronic marker inside USB-C cables that identifies cable capabilities to connected devices.

When shopping for USB-C cables, e-marker presence is the single most important indicator of quality. Cables with e-markers identify themselves to chargers, enabling full power delivery above 60W and high-speed data modes. Budget cables often lack e-markers, silently limiting your devices to lower performance.
