Hey,

I have a Dell TB3 dock for my laptop, the dock has a TB3 cable hardwired to itself.

The cable on the dock seems good but as I have already sent this thing back once (a sound issue) I am worried that one day the cable could give out on me with the fact I plug and unplug it fairly often.

Do extenders or connectors exist for TB3? A quick google leads be think no, it's generally TB3 to USB.

Figured if I can attach an connector of sorts then it might help save any ware of the cable itself

Cheers

Isn't TB3 physically the same as regular USB-C?

Not internally, USB 3 maxes out at 10GBs(?) but TB3 is 40.

Hard wired cable into the dock? That's not ideal, for the reasons you mention.

I don't see any Thunderbolt extension cables in NZ at my suppliers. Thunderbolt cable https://www.promate.net/products/thunderlink-c20 is available in NZ and has an end of September ETA, but I don't see a joiner anywhere.

You might have to go to Amazon. https://www.amazon.com/DISDIM-Thunderbolt-Extension-Charging-Compatible/dp/B075MBS6JY

Thank you for the reply.
I had been looking at that Amazon one actually.

Interesting read, I'll have another go over it tomorrow.
I've managed to attach my dock to the underneath of the desk so there is less movement now, hopefully that helps in the long term.

Cheers again
