Treedix USB Cable Tester with Acrylic Case

Check the wiring of your USB cables with the Treedix USB Cable Tester. Its 24 LED indicators show connections at individual pins, helping you inspect cable wiring and distinguish power-only connections from connections that also include data lines.

• Supports cable connections using USB-A, USB-C, USB-B, Micro-B, Mini-B and Lightning, as described in the manufacturer's manual.
• Includes an acrylic protective case.
• Powered by a CR2032 coin cell or the dedicated USB-C power input.

To test a cable, connect its two ends to the appropriate ports on the tester and compare the LED pattern with the manufacturer's reference guide. Keep the cable disconnected from phones, computers and other devices during testing.

Know its limits: This is an electrical wiring checker. An LED result does not establish that a cable is free of hidden electronics or malicious functionality, and it does not certify real-world data speed or charging performance. Treedix warns that shorted pins, diodes, active electronics and other cable faults can produce inaccurate results.
