In Windows 11, is there a way to find how many watts my USB ports give?

I ask because I'm looking to use an internal SSD with an external enclosure and I'm trying to make absolutely sure that my ports offer enough power for it. I'm pretty sure USB C offers 100W according to other sources but I want to make sure. I want to know that my ports can give more than enough so everything works properly.

Also, I'm using a gaming laptop.

    Hi! I'm Luis, a fellow Microsoft Community Member . Thanks for reaching us out here.

    You can not exactly get the exact amount using Windows alone. The closest thing would be to get the Power State

    Device Manager>Universal Serial Bus Controllers>Right click on "USB Root Hub (USB3.0)>Properties>Details Tab>Property>Power Data.

    You will then see the value D0 to D3

    D0 being maximum and D3 Sleep mode

    You can optionally use a third party software such like USBDeview to get the exact amount of energy

    Hi, sorry to randomly pop in again but is there supposed to be any actual number next to these values? I don't see anything. Everything in my device manager just says this:

    "Current power state:
    D0"

    but there isn't actually any value or number by it indicating the power.

    Thank you so much! Also, I’ve recently read that different versions of USB A and USB C have different power outputs, USB 2.0 being at 2.5W, USB 3.0-3.2 being at 4.5W, and USB C being at 100W and sometimes 240W. Is that right? So ideally I should just use a USB C port, which would be more than enough, right?
