Razer's Thunderbolt 4 dock connects over a single upstream Thunderbolt 4 (USB-C) cable that delivers up to 90W of laptop charging. Three downstream Thunderbolt 4 ports handle displays and high-speed peripherals, but there are no native HDMI or DisplayPort outputs — you drive monitors over USB-C/Thunderbolt or use an adapter. A UHS-II SD reader runs at up to 312MB/s, and three 10Gbps USB-A ports plus Gigabit Ethernet and a 3.5mm combo jack cover the rest. Underglow Chroma RGB lighting is the namesake flourish.
