CalDigit 40Gb/s Type-C cables offer the best performance possible from such a small interface. Whether you're using high performance RAID storage or connecting the latest Thunderbolt devices, CalDigit Thunderbolt 4 / USB 4 cables are among the best available. A Thunderbolt 4 cable can provide fast transfer speeds, connect an 8K monitor and power devices. Our cables offer 20V 5A, up to 100W of Power Delivery. Some cables on the market can only provide up to 20V 3A, 60W or lower. The ability to provide full 100W power enabled device charging from Docking Stations or Monitors at the maximum rating instead of being limited by the cable's maximum load. If you have used Thunderbolt cables in the past you know that they can get a bit warm. CalDigit cables are specifically designed to improve thermal performance to withstanding higher wattage than other cables. That's why our cable is capable of delivering up to 100W of power.
