Wesley;

No this is not a USB wire checker. It's designed to only measure Voltage
and Amperage flowing in a USB circuit.
There are such things as a "charging cable" vs a "data cable". But it
depends on the manufacturer, as an example
my 2012 Android Nexus 7 is designed that when the data pins are shorted
together the unit will thus default to "fast charge" mode. Here is the
pin out of a standard charger:

So I since you really can't fix a "cheap cable" I would recommend
acquiring a good data cable from a source that you can trust. I would
NOT trust any cables sold on eBay sourced from china.

My current research shows that the app "Charging Report" ( for Samsung
Galaxy Handsets ) does accurately report mA
https://play.google.com/store/apps/details?id=com.playfulgeeks.chargingreport
or at least matches what the USB tester states up to at lease a
hundredth of a mA.

Will this tester tell my why?
