Measuring the voltage, current, power and capacity (current over time or amp hour) flowing through USB plugs is easy with a USB tester. Simply plug the ISB tester between the male and female USB connectors that you want to measure. The tool does the rest.
I have only used the Drok USB tester that is in my videos. I don’t know which other other ones are better or worse for the price. I have the USB version. There are other USB types available, so pay close attention to what it is when you are looking to get one.
