How to check USB port for Power on Windows 10


There 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 Manager




With 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 application




If 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 Port’s 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.

Hello Adam,

We appreciate the details that you've provided about your USB port issue. This may have occurred due to software conflict or a hardware issue. For us to help you with this, kindly answer the following questions for further research:

• What is the current build and version number of your Windows 10? To check, press the Windows key, type winver, and press the Enter key.
• We'd like to clarify the uninstalling and installing usb hub part. Have you tried
  
  updating your USB port driver? Have you tried uninstalling the driver and let Windows install the compatible driver?
  
• Have you tried rolling back the USB port driver to its previous version?

Meanwhile, in order to save power, Windows switches your USB controllers off when they’re not in use. We suggest that you check your Power management settings:

• Type Device Manager in the Windows search field and open it.
• Expand the Universal Serial Bus controllers branch.
• Double-click the first USB Root Hub device in the list.
• Click the Power Management tab.
• Un-check the Allow the computer to turn off this device to save power checkbox, and click
  OK.
• Repeat steps 3-5 for each USB Root Hub device in your list of Universal Serial Bus controllers.

We'll be waiting for your reply.

Average Power Output
The average power of a USB port is about 5 volts. Your USB device will be able to draw out a maximum of 500 milliamperes (mA), but most default to 100 mA until prompted to provide more power by the device software. If your device requires more power than
500 mA, it may work slower or not at all while plugged into your computer.
