USB Cable Short-Circuit Tester — Type-C / USB-A Board

Free shipping · 6–12 days · tracking

USB cable short-circuit tester — compact Type-C / USB-A test board to check cable continuity, shorts, and data-line faults before you blame the phone or charger.

One board SKU for everyday cable triage on the repair bench. Plug the cable under test and read the LED / switch indicators — no guesswork with a bare multimeter every time.

Features

- Type-C and USB-A / Micro-style cable check on one small board

- Short-circuit / open-line indication for quick pass-fail

- Handy for sorting customer cables and shop stock

- Bench tool only — not a power supply or charger

How to use

- Connect both ends of the cable to the matching ports on the board

- Power the tester as shown on the silk / legend

- Watch the indicators for short, open, or normal data/power lines

- Retire or repair cables that fail before they take out a port

Typical jobs: shop cable QC, customer drop-off triage, and checking aftermarket Type-C / USB leads on the phone repair bench.
