I got an HC703 7 in 1 type C USB hub as a gift. The details mention USB PD(100W). I was curious about how to make use of this high-power feature. The hub comes with one USB Type C cable, which I connect to my laptop's USB port. I understand I can charge my phone via the hub's USB PD port. However, because the hub is connected through the laptop's USB port, its power output is limited by the laptop's capabilities. Can a standard laptop USB Type C port really deliver 100W? If not, the hub's PD port might not be very effective.

It's not about "USB C." USB C refers only to the physical design, not the technical specifications. Any USB C connection can be built to work with different USB standards and requirements. The important factor is which specific standard the port supports—such as USB 3.1 Gen 1, Gen 2, Gen 2x2, etc.—before you assess its capabilities for charging or data transfer.

Only the PD USB C port is capable of charging

They all have the ability to charge, though not necessarily at identical speeds. Additionally, certain ports that support faster charging may not be able to transmit data, which contradicts your suggestion. Some devices can send information, while others cannot, but every one of them can "charge," with possible variations in speed based on the port type.

The USB-PD 100W capability allows connecting a charger to the hub, which then powers the laptop. This setup is designed to utilize your laptop's USB-C charging port while also adding additional ports simultaneously, making it efficient for dual purposes.

I just wanted to mention that a 100W charger is necessary to get the best performance. Usually, the hub takes up 15W for powering it, so you’ll receive 85W in total.
If you use the original USB-C charger that came with the laptop—often around 65W—you’ll end up with a lower charge, about 50W.
The positive aspect is that you’ll have an additional external display and more extra ports.
Hope this clears things up,

When connecting via a hub or using a direct USB port on a PC, it doesn't involve a "charger," making this point completely out of context.

You cannot power a laptop using this hub without supplying input power to it. However, other small devices can be charged through the USB type A/C port, albeit at a very low rate of 7.5W or up to 15W.

The charging features are available for the device in question, generally, regardless of the specific model, as long as it meets the requirements. Claiming otherwise would be misleading.
