Read guide →Before replacing a cable, isolate the problem
1. Define the symptom
Is charging slow, video missing, file transfer slow, or a network link unstable? One symptom at a time makes testing easier.
2. Simplify the connection
Remove hubs and adapters when possible. Test a direct connection with a known-good compatible cable.
3. Verify specifications
Check device ports, required signal direction, cable rating, and power limits in official documentation.
Questions we hear often
Quick answers
Will any USB-C cable work with my monitor?
No. The computer’s port must support video output and the cable or adapter must support the required display signal and mode.
Can a higher-wattage charger damage my phone?
Compatible USB Power Delivery equipment negotiates power; a larger advertised maximum does not mean the phone must draw it. Use compliant, undamaged accessories and follow manufacturer instructions.
Why does an adapter work in one direction but not the other?
Many adapters convert signals in one specified direction. Read the source-to-display direction and active conversion requirements before purchasing.
Is a more expensive cable always better?
No. A clearly specified cable that meets your actual requirements is usually a better choice than paying for features your devices cannot use.
