alt Hacker News> The Neo charges faster if you plug it into a more powerful power adapter, in either USB-C port.
The fact that the "usb 2" port works for (fast) charging is a big win. That means you can charge and use the fast usb port at the same time.

For some use cases, you can do that with a single USB port, too. For example, a single USB cable connected to a monitor can both send video and charge the laptop.

USB-C PD (power delivery) has been a standard for over a decade now. I first used it on a Nexus 4 or 5, and later on a Chromebook Pixel in 2016. It would be surprising for apple to not use that standard, particularly when both ports are probably run from the same controller.
I think that makes it a non-standard implementation though (I agree it's certainly more practical for the user), sounds like it's usb-c pd but with nerfed data, an odd choice that feels like it would actually have cost more to develop than just adding two identical usb-c 3.x ports...
