Two cables can fit the same port and still support different jobs. USB-C describes the connector. Check the specifications for the cable, device and connected equipment before buying a replacement or assuming a port is broken. The artwork is an educational illustration; cable color does not tell you its capabilities.
Match the cable to the job
Look for the charging power rating, supported data speed and video capability in the manufacturer specifications. A cable that charges a device is not automatically suitable for every monitor or high-speed file transfer. The device port and connected equipment must support the intended function too.
- Charging: check compatible power requirements and the adapter as well as the cable.
- File transfer: check the supported data rate.
- External display: confirm that the computer port, cable and display connection support video.
Use a simple compatibility check
Find the exact device and cable model on the original packaging, order details or manufacturer page. If you have another undamaged cable already confirmed to support the same task, comparing it can help narrow the issue. Do not force a connector or keep bending a cable to make it work.
Know when specifications are not the whole answer
A compatibility check cannot repair physical damage. Repeated disconnects with suitable equipment, a damaged connector or persistent charging trouble may need an evaluation. Stop using equipment with visible damage or unusual heat. Tell the repair team which device, cable and adapter you tried and what happened.
