How to determine the voltage output and maximum current of USB hub ports in Windows 10

There are different methods to check the voltage output and maximum current of USB hub ports in Windows 10:

1. Device Manager: The Device Manager provides information about hardware devices connected to your computer, including USB hub ports. Here’s how to use the Device Manager:

1. Press Windows key + X and select Device Manager from the menu.
2. Expand the Universal Serial Bus controllers section.
3. Right-click on a USB hub port and select Properties.
4. In the Properties window, go to the Power tab.
5. Here, you will find the Power Required field, which indicates the maximum current required by the USB hub port.

Alternatively, you can use third-party software to check USB hub port voltage output and maximum current. There are various tools available online that provide detailed information about USB ports and their power capabilities.

Other methods:

There are alternative ways to determine the voltage output and maximum current of USB hub ports:

1. Manufacturer’s Specifications: Check the manual or visit the manufacturer’s website for the USB hub device to find detailed specifications regarding voltage output and maximum current.
2. USB Power Delivery: USB Power Delivery (USB PD) is a charging specification that allows higher power delivery through USB ports. USB PD-compatible devices often display their power requirements, including voltage and current, on the device or packaging.
3. USB Ammeter: Using a USB ammeter device, you can directly measure the voltage output and current of USB hub ports. These devices are widely available and provide real-time measurements.
