Need recommendation for bus-powered Thunderbolt 3 hub / dock?

[timidhermit]

I like to know if there exists a Thunderbolt 3 hub or port that can be entirely bus-powered by USB-C. I am also looking for a device for which the Thunderbolt 3 port has Thunderbolt 2 backward compatibility. This way, I can connect a Thunderbolt 2 device (such as my Mac Pro 2013) to it if needed.

I searched for the typical models from OWC, Belkin, and IOGear, all of them appeared to require an AC outlet. However, there are so many models from these manufacturers that I cannot be uncertain. Moreover, some reddit thread I read awhile ago (can't find the post anymore) said that such bus-powered hub or port was released and did not give out any specific information.

Any suggestion?

There are bus powered TB3 devices, but I’ve never seen a bus powered TB3 hub. Power delivery to hub attached TB3 downstream devices would seem suspect to me. What TB3 downstream devices would you attach to the bus powered hub?

@timidhermit Thunderbolt devices have to be Intel Certified, and nothing gets certified if it can’t supply the TB/USB-IF required power (15w per USB-C port).

So bus powered TB peripherals with downstream ports don’t exist.

There may be ’TB-compatible’ knock-off products out there.
Or USB devices that are marketed as 'Thunderbolt' because they work when plugged into a port on a 'Thunderbolt Mac'.
They won’t work as you want unless they are properly TB, and have an external power source.

Because of that, when Apple introduced their two-way TB3><TB2 adapter, they decided not to include power transfer wiring, because both ends needed to plug into a TB dock or hub, which would have its own power supply.

A self-powered TB3 dock will work connected to a TB2 Mac, using Apple's adapter.

My advice is DON'T do this.
Get a tbolt dock with its own power supply brick.
It will serve you MUCH better.
