Use a third-party software program to find out your USB properties.

Use a USB voltmeter to measure the power output of your USB ports.

Use the Device Manager to check the power output of your USB ports.

Meanwhile, some third-party software programs can detect the properties of your USB port, including the power output. You can use specialized hardware known as a USB Voltmeter to check the power supply of a USB port. However, thatвЂ™s not the only means thatвЂ™s available to you. You can do so with the help of the Device Manager. You can find out the actual power output of your USB ports as well as the amount of power that is being used by your connected devices.

How to Check Power Output of a USB Port on Windows 10

USB 3.0 charging downstream ports can supply up to 1,500 mA.

USB 3.0 standard downstream ports can provide up to 900 mA.

USB 1.0, USB 1.1, and USB 2.0 standard downstream ports can supply up to 500 mA (milliamperes).

Here are what different types of ports can supply: However, standard downstream ports are for data transfers only. A charging downstream port, also known as a charge and sync port, can charge your connected device while enabling you to send and receive data.

However, sometimes, you may find that your PC also has a standard downstream port (SDP). On a desktop PC or laptop, youвЂ™d usually have charging downstream ports (CDPs). So, how much power can a USB 2.0, USB 3.0, and USB 3.1 port supply? Each time a new USB standard is introduced, we witness an increase in data transfer rate and power output. Universal Serial Bus technology has seen a couple of improvements since the inception of USB 1.0 in the 1990s. One thing every computer user must know is that not all USB ports are the same. If it is inadequate, you might not be able to use your USB device on your computer. Since power is an essential factor in USB usage, you must learn how much your ports are supplying. Well, itвЂ™s all related to the power output. Perhaps, you notice that a peripheral seems not to be working as well as it should on one port but works perfectly on another port. Have you ever wondered why sending files from your computer to your external hard drive, SSD card, or flash drive seems to drag on forever on one USB ports? However, when you try a different port, the transmission is much faster. Moreover, the power outputвЂ™s capacity will determine if your device can only run keyboards, printers, and mice. However, did you know that the power output of your computerвЂ™s USB port determines how fast you can transfer files or charge a connected device? Capabilities for facilitating system backups and large file transmissions also depend on it. ThatвЂ™s how the ports can read peripherals, such as a mouse, keyboard, camera, smartphone, hard drive, and other storage devices. Your PC supplies current to its USB ports.
