USB current, voltage and capacitance tester KWS-V20

If you work with USB devices, then you certainly know how important it is to have the right tool to check and optimize these devices. In this article, we will review the KWS-V20 USB tester, which is a reliable and efficient tool for testing and optimizing USB devices.

What is KWS-V20 USB Tester?

KWS-V20 USB tester is a compact device that allows you to test and optimize USB devices. It is equipped with an OLED display and control buttons, making it convenient to use. With the KWS-V20, you can check the power, voltage and current of the USB port on your computer or any other device with a USB port.

How to use KWS-V20 USB Tester?

Using the KWS-V20 USB tester is very easy. Simply plug the device you want to test into the USB port on the KWS-V20 and you will see the power, voltage and current information on the display. This will help you determine if the device is working properly, and if not, what problems might be.

In addition, KWS-V20 USB tester can also be used to optimize USB devices. You can use it to measure the power consumed by a device and find out which devices are consuming too much power and can be optimized for better use.
