Teardown of 140W MacBook Pro Power Adapter Shows What's Inside

Apple has introduced new technology to the 140W power adapter, which ships with 16-inch MacBook Pro models. This adapter is the first to use gallium nitride (or "GaN") technology to reduce its size. It also features USB-C power delivery 3.1. ChargerLab published today a teardown video of the 140W adapter to give those interested a peek at what's under the hood.

While the teardown video includes general measurements and testing the power adapter's performance, ChargerLab completely disassembles it to access the internals. Although the analysis section of the teardown video is very technical, it is well worth the effort if you want to learn more about the particular chip setup Apple uses.

This adapter is compatible with all devices that support USB-C Power Delivery 3.0. The MacBook Pro models can also charge with USB-C Power Delivery 3.1 chargers made by third-party brands.

The 140W power adapter comes with the 16-inch MacBook Pro. It is also available at Apple for $99.
