This is a good example of where this fails. The Fnirsi FNB58 does not report GND vs VCC measurement of cable resistance. Cables fail due to GND resistance NOT due to VCC resistance. Other than that single test function it only reports what the cables tell it. It can't tell you if there is poor shielding between the cc pins and USB causing interference that will cause dropouts or if the inductance is too high and it will damage your devices or any of the other dozen compliance tests. You can use it to see if charging is dropping out but this is not a cable test. For the price of this tester you could buy 6 certified premium USB-C charging cables
