USB-C w/ PD hubs. Why only Type-A receptacles?

[iamGavinJ]

Hi,

I've been looking for a USB-C hub with power delivery for a while now and I was wondering if there is a technical reason all of the products currently on the market offer a USB-C plug to connect to the host, one additional USB-C port for the power delivery, yet only offer Type-A receptacles in the hub?

When I bought my new MacBook I invested in USB-C cables for my existing peripherals to avoid the need for a convertor which was great but creates the issue with charging the MacBook when anything else is plugged in.

What I really want is a USB-C hub with power delivery offering USB-C ports. Does this exist? Is this even possible? I read briefly about the PD specification for upstream and downstream ports and got me wondering if what I'm after is even technically possible. And on that point, would the PD controller be able to deal with the situation where more than one power source could potentially be plugged in at the same time?

Thanks.

Well because in the larger market nobody uses typeC to typeC. My phone charges from a typeA at the charger into a typeC for my phone.
Its cheaper, and much more universal for them to go from typeA to typeC.

I do think its odd that I cant find a single hub that you describe though.

there is no technical limitation per say.

all devices i'm aware of connect with usb-a for pc interface so there is practically zero demand for a type c interface

it can be equally hard to find some 3.5mm 4pole to 3pole cables outside of typical common as dirt male/female arrangements. without market demand, products available might be little to nil.
