This is a very handy device if you have anything with a USB Port on it. This will show you both current and voltage. It can be incredibly useful to determine what charging issues are on USB devices.
I wish the usb port rotated, sometimes it will wind up with the display facing down or away from you and can be hard to read. This can be solved with a male to female USB extension cable, but still the design would be improved it it had a rotate or swivel on the male port.
Very handy, I used to have an old, cut off USB cable that I used to check voltage, this is much cleaner and easier to use.
Get one if you want to know what's up with your USB ports and charging.
