What is /different/ about a 60 watt USB-C cable that says it charges just
about everything, including Android, iPhone, Mac, Dell, Thinkpad, Nintendo
and Apple TV?

Is it thicker wires?
Better insulation?
Different wiring inside?

What makes it 60 watts?

I'm thinking of buying this USB charger with an included 60 Watt cable. https://www.amazon.com/dp/B0DQ7XFYQB
That $17 charger is only 35 Watts but the cable is said to be 60 Watts.

What is it about that USB cable (or any USB cable) that makes it 60 Watts?

It says it works for iPhone 16/15/14/13, Galaxy S24, Note 20, Pixel 8
Pro/8/7, iPad/iPad Mini, MacBook, iPhone 15/15 Pro/15 Pro Max,
iPhone 14/14 Mini/14 Pro/14 Pro Max , iPhone 13 /13 Mini/13 Pro/13 Pro Max, iPhone SE (2020), Samsung S22/S21/S20, Samsung Note 20/20 Ultra/10+/10,
AirPods Pro/3, Nintendo Switch, MacBook Air 2020, ThinkPad X1/X390/E490,
Google Pixelbook, Dell XPS 13/9360/9380, iPad Air 5/4, iPad Pro
2021/2020/2018.

Most cables don't even say what their wattage is, like this one. https://www.amazon.com/dp/B0DNFHM4TW
But they still say they work with almost everything that is out there.
Like this one which says it works with Apple TV but doesn't say the watts. https://www.amazon.com/dp/B0DPG21DZS

This one is 100 watts.
https://www.amazon.com/dp/B0CKZ7V21Y

This one is 240 watts.
https://www.amazon.com/dp/B09PB8DJ28/

What is it about a USB-C cable that makes it high wattage, and can we tell
by looking at something in the cable or by running some kind of test?
