Apple 140W MacBook Pro charger redesign breaks some accessories

Apple shipped some new 16-inch MacBook Pro units with a redesigned 140W power adapter on April 2, 2026, and the change breaks compatibility with some existing accessories. 9to5Mac reported that the issue affects the 140W charger bundled with the new 16-inch MacBook Pro, but not every buyer appears to receive the revised design.

The reported change is a physical redesign of Apple's 140W power adapter rather than a new charging standard or a software update. The source did not specify which accessory models are affected or how many charger variants Apple is shipping, but it said some accessories that fit the previous 140W adapter no longer work with the new version.

This report concerns MacBook Pro hardware rather than eSIM, eUICC (embedded Universal Integrated Circuit Card), or Remote SIM Provisioning. It is relevant to the broader Apple device ecosystem because accessory compatibility changes can affect users who rely on third-party charger mounts, cable organizers, or travel accessories designed around earlier Apple power adapter dimensions.
