Professional Review of above USB meter:

This meter has proven helpful in my understanding of why some outlets charge various USB devices faster than others, and that the quality of the USB cord, and its length can make a huge difference.

This linked meter can test voltage at the end of a micro USB cable, and the voltage drop can be significant.

Gee thanks.... There's another $10 I need to spend.. You're correct about chargers and cords. I'm finding out why some things charge, others done, and the differences in wall worts. It's amazing the charge differences in various devices
