Question What is the right way to use the USB PD port on a USB hub

[hw_user]

I received an HC703 7 in 1 type C USB hub as a gift. The specification says USB PD(100W). I was just wondering how can I use this 100W PD feature. The hub has a single USB Type C cable which I connect to the USB C port of my laptop. I know I can charge my phone by connecting it to the USB PD port of the hub. Since the hub is connected to the laptop USB port, it is limited by how much power the laptop USB port can provide. Can a regular laptop USB Type C port provide 100W ? If not, the PD port on the hub is probably not very useful.

It's not about "USB C.

"USB C" is ONLY the "form factor", not the spec. ANY USB C port can be designed to support a variety of different USB specifications and standards.

It's about what SPEC that USB C port supports and they are absolutely not all the same. You need to know what spec, as in, USB 3.1 Gen 1, USB 3.1 Gen 2, USB 3.2 Gen 1, USB 3.2 Gen 2, USB 3.2 Gen 2x2, etc. that the specific USB C port in question was designed to support before you can make any determination of what exactly that port can support in terms of charging or data transfer speeds.

No, only the PD usb c port can be charged

Wrong. They ALL can charge, just not necessarily at the same speeds AND some of the ports that charge at higher speeds cannot transfer data, which is exactly opposite of your indication. Some can transfer data, some cannot, but ALL of them can "charge", potentially at lower or higher rates of charge depending on the type of port it is.

The USB-PD 100W feature of this hub is so you can plug in a charger into the hub, which will then charge the laptop. This is meant to be able to use your laptop's USB-C charging input (assuming the laptop charges via USB-C) and add ports at the same time, so you effectively kill two birds with one stone.

Thanks, I think this is the right answer.

Just wanted to point out that you will need a 100W charger to take fully advantages. There is usually a 15W reserved by the hub to power it so you will get 85W output.
In case of using original USB-C charger that came with the laptop, often 65W, you will get lower charge (50W)
The bright side is that you get another external display plus some more extra ports.

Hope this helps,
Triple

If you are charging from a hub or directly from a USB port on a PC, you would not be USING a "charger", so this is totally irrelevant to the conversation.

You can't charge a laptop with this hub without providing an input power to the hub. And yes, you can charge other small devices via USB type A/C port but very slow saying 7.5W or max 15W.

Charging properties are INCLUSIVE to the device in question, mostly, independent of WHAT device it is, so long as it adheres to the standard. Saying otherwise is just, nonsense.
