OK, you're welcome & good luck my friend. :)
Question marked as
Apple's 140W charger is intended for charging Apple laptops. See https://www.asme.org/topics-resources/content/explore-the-basics-of-usb-c-and-usb-power-delivery. USB-C power delivery is negotiated by devices. Notionally power is delivered at 5, 9, 15, or 20V, and at up to 5A, making for a maximum of 100W. Presumably Apple have extended the specification slightly. If you want to use this power supply to run a third party hub you will need to make sure that it is able to correctly negotiate the amount of power that it want (watts=volts * current) and then deliver the correct regulated current to each of your devices.

That would appear to 5A. Anything greater would likely start to fry cables.

Very clear explanation! :) 👍
If you are trying to find out if it will damage your iPhone, it won't.
The iPhone will only pull as much power as it needs. You can use the 140watt charger of a Mac to charge an iPhone without any issue.
