    It has been really useful for me beacuase I wanted to test mi phone charger and several usb cables that I have at home. I have been able to test their quality and, for further purchases, buy only those who guarantee an amount of A that allows to charge my phone in a reasonable time.

    Tells you the voltage and current with very good accuracy (tested with another device). Easy to carry and allows usage of the USB port while monitoring.

Thought I was running out of USB ports, but thanks to this meter found out how many non-powered USB devices could be connected to each port with a USB hub, for example two 2.5 HDD's and a USB fan,...
