Laptop USB ports power delivery

[3alfa3]

Hello,

I have Lenovo V17 g4 iru 17.3 Laptop and was wondering does usually USB ports on laptops share power delivery, or every single USB port is separated in that sense?

Asking because all of them are occupied and one of them is used by Topping DX1 which can theoretically demand almost all the power that a USB port can provide.

Separated. Every port delivers power according to the specification (usb2,3,3.1...)
Thats how must be.
Sometimes the laptop manufacturers are cunning providing ports with shared capabilities including the power supply. Read careful your laaptop/MB manual.
