Neat diagram that I hadn't seen before. I plan to keep this image saved so I can refer to it and make sure I am using adequate ports as I swap cards around.

is the usb A high power still limited to 5V?
This means it'd need high current ratings (and heat dissipation) to deliver higher power at that voltage.
compare to say usb-C that can negotiate up to something like 20V, if all links allow it.
this means your usb-c can offer higher power with lower current rated components..
For basic solidstate power supply doubling the V ratings from say 6V to 12V will likely be cheaper than doubling Amp ratings from say 3A to 6A.
but for sure in a laptop managing the heat will be a consideration.
Maybe theres a version of USBA that can use the data lines to negotiate power - in which case this would be non-standard.
They should just state peak and continuous V, A and W for each port, and also for the set of ports as a whole. maybe in different input/battery scenarios. I assume a third party, or home gamer could create their own plug in module to do whatver, but it'd be helpful for them to know the electrical ratings.
