Sadly, there’s not much in the way of documentation, so it’s unclear how many display modes there are. I’m also confused by the “real-time” voltage and current reporting, because we’re also told it takes 5 seconds to detect “abnormal pins”.

The VBEST’s device is very similar to the A2C caberQU and C2C caberQU boards used to respectively test USB-A to USB-C and USB-C to USB-C cables. But instead of relying on LED for each pin, the VBEST Tail Insert Detector features an LCD display, and it also supports Lightning devices instead of just USB-C devices.

The VBEST USB-C and Lightning port tester can be purchased on Banggood for $18.69 as part of a Flash sale, but the “normal” price is $69. If you’re happy with LEDs and a USB Type-C support, cable testers can be purchased on Amazon for just $15.
