2UUL PW31 PortCheck Pro Tail Plug Automatic Detector

The 2UUL PW31 PortCheck Pro is a disassembly-free charging port and cable diagnostic tool built for Type-C and Lightning (8-Pin) interfaces. You plug it directly into the port and get an instant pass or fail reading through a color-coded display, so you skip the guesswork on dead charging complaints. A built-in 300 mAh battery keeps it ready on the bench without needing external power for quick checks. Technicians use it to isolate port-side faults from motherboard-side faults before opening a device, cutting diagnostic time significantly. The large LCD screen shows real-time measurement data, giving you a clear, repeatable reference point for every port you test in your workshop.
