Yes, the length of a USB-C cable can affect charging and data transfer speeds, depending on several factors. Higher quality cables with thicker wires and better shielding will perform better over longer distances. For example, USB 2.0 cables have a recommended maximum length of 5 metres (16.4 feet), while USB 3.0/3.1 cables are best kept to around 3 metres (9.8 feet). Longer cables can cause voltage drops that reduce charging speeds, and signal degradation can affect data transfer rates.
To maintain optimum performance, it's important to use high quality, certified cables, especially for longer distances, such as the Cabletime USB 3.2 Gen 2 Type C to USB Type C cable, which can deliver up to 20Gbps at a maximum length of 5m.
