USB Extenders: Power and Data Speed Rarely Both Max Out on Same Cable

USB extenders and long cables can technically move both power and data, but rarely deliver top performance in both categories at once. For example, Anker's 10-foot 240W USB-C cable transfers data at just 480Mbps, while Icron's 328-foot extender hits 5Gbps but only supplies 6W per port. USB-IF's compliance rules also don't cover generic male-to-female USB-C extension cables, even though such cables aren't illegal to sell or use.
