I'm going to build the DIY Perks secondary monitor from a laptop screen but I'm not entirely clear on how to power it as described in the video. 

My laptop uses a Max 65w USB-C charger that can output 20V/3.25A, 15V/3.0A, 9V/2A, and 5V/2A.

In the video, an extension cable that looks specific to the laptop is spliced and the voltage step down board is used to power the monitor. I don't have a strong enough understanding of how USB-C power cords work to emulate this for my setup. I see 60w and 100w USB-C cables available, but I don't know how the power regulation works if I want to splice on of these in the same way.

Any advice/recommendations?
