Every not-broken USB C cable allows for 480Mbps USB 2 speeds and 60W charging. In USB C terms, it doesn't get any more basic than this; that's as low-and-slow the specification tolerates.

The issues come into play with going beyond that. USB 3 speeds? USB 4? Thunderbolt? DisplayPort (4k uncompressed video!) alt modes? 240W charging? These are all practical things that regular people use USB C cables for every day, but they require very specific support from the cables themselves, and that support is widely varied.

Your cables work fine for what you're doing with them, but you're really barely scratching the surface of the kinds of things that can be done. :)

It’s because you are using the lowest use case for usb (like most people). Literally everything can manage 65w power only.

All of these “usb sucks” posts are about using multiple 4k 120hz monitors dasychained while pumping 140w and a handful of other dongles hanging off which pushes usb to the limit and requires carefully selecting the highest quality cables.

It's surprising to me you've been that lucky with Belkin. They do not have a good reputation. Maybe cables are easy so that's an easy bar to pass.

What 6 port charging hub do you have? I have a broken UGREEN one.
