Summary
WhatCable is a practical tool that helps users identify USB-C cable capabilities in plain English. It diagnoses whether the cable, charger, device, or Mac port is causing issues like slow charging, slow SSDs, dock problems, or display failures by showing cable speed, charging power, and e-marker data.
Key quotes
· 3 pulledEvery USB-C cable looks the same, but some charge fast, some are slow, some handle displays, and some quietly break your setup.
WhatCable makes that visible in plain English.
It basically tells you whether the cable, charger, device, or Mac port is the problem, so you don't have to guess why your SSD is slow, your dock is acting weird, or your display refuses to work.
