DELL YI2C Magnetic 2 USB-C Charging Cable 85W 20V 4.25A 5ft Braided Black

What this cable does and who it fits

This DELL YI2C cable delivers up to 85W at 20V and 4.25A through a USB-C magnetic connector designed for MacBook Air and Pro models released between 2012 and 2017. The second-generation magnetic tip snaps on quickly and helps protect the laptop port from wear. A 5-foot nylon braid adds durability and reduces tangling during daily use. It is a charging cable only and requires a separate power adapter.

Behaviour under sustained load

The cable is rated for a continuous 85W output, matching the power draw of a MacBook Pro under heavy workloads. Its 20V, 4.25A specification means voltage and current remain stable during extended charging sessions rather than throttling after a short burst. The braided jacket resists heat buildup and physical stress when the cable rests on a desk or wraps around a power brick for hours. MacBook Air owners must supply a PD65W 20V or higher adapter, while MacBook Pro users need a PD85W 20V or higher adapter to reach the rated output.

The spec that decides fit

Compatibility is limited to MacBook Air and Pro models manufactured from 2012 through 2017; newer or older machines will not connect to the magnetic tip. Buyers must verify the release year in the “About This Mac” menu before purchasing. The cable itself carries no power supply, so a suitable 20V PD charger is a separate requirement. Users needing a straight USB-C plug or support for post-2017 laptops should look elsewhere.
