I have a cheaper version, it does basically all one needs by telling you how many conductors the cable has, if it's only got 4 lights lit up it's a simple USB2, more power LEDs is a higher power charging cable, more data pairs, higher data throughput/USB3, nearly all of the lights (usually bar 1 of the CCX) it's full DP/Thunderbot, data, charging, A/V etc.

Sometimes it even shows USB-C connectors that are only wired for one orientation!

More often than not just knowing the contact has OK connection is good enough.

As far as I know the marker chips is mostly to tell the devices to not abuse the cable.

For USB, if it can carry 65W+ of power to my laptop as well as the Keyboard/Mouse inputs, 4K/60Hz display and audio back to the monitor as well as KB/Mouse and perhaps some external storage or network adapter, that's a pretty amazing cable.

I also have preferences between my cables by the quality and aesthetic, I prefer some over others because they look or feel nicer even if in testing they contain the same conductors, but that's just ... me.

I currently have 3 such cables connected to my work laptop each sending 4K/60Hz video to each of my 3 x 4k monitors, audio to my soundbar and one of them is powering the laptop at 90W and sending my keyboard, mouse and webcam inputs back.

I suggest finding something else, electrical tape starts coming off after a few years, leaving behind sticky residue that's impossible to remove without some kind of solvent. Same goes for masking tape.

You could even do combinations of colors like on resistors.

Might get sticky residue after a few years

Love this, that sounds awesome. Thanks for sharing!

Whoops, thank, I can't read - I misread label maker as label marker!
