Power Output of
USB Ports on Windows 10, this post is for you.
How to check USB port for Power on Windows 10There are two methods by which you can check the Power Output of USB Ports on Windows 10:
■ By Device Manager
■ By Third-Party application
Let us talk about them in detail.
Using Device ManagerWith the help of Device Manager, you can check the Power Output of USB Ports on Windows 10.
1. To do that launch
Device Manager by
Win + X >
Device Manager.
2. Expand
Universal Serial Bus controller, right-click on
USB Root Hub or
Generic USB Hub, and click
Properties.
3. Go to the
Details tab and from the
Property section select
Power data.
4. Now, you can see the Power Output of your USB Port from there.
5. You will see something like
D0. The higher the number, the lower the Power Output of your USB Device.
For example, in this screenshot, the
Current power state is D2, which is somewhere in the middle.
Using Third-Party applicationIf you want to know the exact Power Output rating in Ampere then go for USBDeview, a third-party application to manage your USB devices.
You need to download and install the application.
Launch
USBDeview and see your USB Ports Power Output from the
Power section.
You may want to use the horizontal slider to reach the Power option.
This can be a bit frustrating if you are checking Power Outputs of multiple ports, so, you can either drag the Power option or double-click on a specific port to know its Power Output.
