You don’t really want that. A thunderbolt cable is both stiff and expensive. They only really make sense to leave attached to the back of a monitor or dock.

What would work better is a flexible 100w+ usb3 cable. You can’t do thunderbolt on it but it’s a tiny fraction of the cost and does everything you’d actually need on the go.

If you actually do want it, this is the do everything cable https://www.apple.com/au/xc/product/MW5H3ZA/A

So much this. I have a few different categories of "known good" USB-C cables because one type doesn't fit all my use cases. Sometimes the trait I need is >100w PD charging at 1M. Sometimes I need 80 Gbps dual 4k video at 3M. Other times I need 40 Gbps .5M to a portable NVMe enclosure. USB-C cables I regularly rely on range from $5 to $100 and weight/size varies >3x.

And in my tiny 'go bike bag' for day trips I need one 2M cable that's thin, coils into a tight ball and weighs nothing yet will charge up to 45w and reliably xfer data at up to 5Gbps (USB 3.1) for quick uploads with optional USB-A and Micro-USB adapters at either end (because I still know people with Micro-USB (though it obviously drops to USB2 speeds)).

At my workplace someone always orders the what they perceive to be the "best" cables. They aren't thunderbolt, they are just oversized with thick braiding. They are all so stiff and heavy you can barely handle a phone while charging without the cable pulling itself out.

I’m sure it’s overkill but I wanted to know how much power my laptop or whatever was actually drawing.

Love this! I got a USB C multimeter and used it to test the output of two dozen chargers. Wanted to see if they supplied the voltage that was advertised. Funny enough, AOHI was the only brand whose chargers actually increased their voltage as my current draw went up. It was like the engineers knew about the resistance in the wire and decided to compensate by upping the voltage slightly.

As an alternative, you could get a stand-alone USB-C power meter which can be used with any cable. That way, when the cable breaks, you don't have to buy a new power meter. Here is an example of one such product (though I've never used this model): https://www.amazon.com/Adapter-Voltage-Current-Extension-Con...

LTT did a lot of work to prove their cables do everything they say:

(these are what I would buy from a sea of cables, not the cheapest, but far from the most expensive)

A thunderbolt cable

This is the solution, but it is 1) expensive and 2) Thunderbolt cables are quite short compared to regular USB-C.

Well they do want it all so they can pay for all, right? :)

Apple sells a 3m one, It’s just $250AUD.

I imagine at that length and speed, signal integrity becomes difficult.

And to be precise, a nice, high quality thunderbolt cable from a reputable manufacturer like Apple or OWC. Protect the cable as it will have been expensive, but it will work very well.

Would it work with USB-C screens and projectors ?
