Build integration and cable freedom

The fixed 2 m MagSafe 3 cable removes the need for a separate charge lead and a spare USB-C port. Magnetic attachment reduces accidental disconnects while the single brick handles the full power path. No extra adapters or docks are required for the listed laptops.

Power headroom and charging speed

The 140 W rating supports PD 3.1 output and can charge a compatible MacBook Pro to 6080 % in 30 minutes, outpacing 96 W and 70 W units. It is sized for M1 through M4 Pro and Max chips under load. Buyers needing more than 140 W or support for pre-2021 models must look elsewhere.
