3.3ft USB4 Cable 40Gbps 240W
This 3.3ft USB C to USB C cable delivers USB4 Gen 3x2 performance at 40Gbps and supports 240W Power Delivery 3.1 Extended Power Range. It handles 8K@60Hz or dual 4K@60Hz display output and is backward compatible with Thunderbolt 4 and 3 devices. Bi-directional reversible connectors simplify every connection.
Upgrade from slower or lower-power cables
Replaces cables limited to 10Gbps or 100W that cannot drive high-resolution displays or charge large laptops at full speed. The jump is worth it when you need 40Gbps data throughput, 240W charging for a 16-inch MacBook Pro, or daisy-chaining up to six Thunderbolt 3 devices through a single port.
Suits creators and power users with USB4
Ideal for professionals connecting docking stations, external GPUs, or dual 4K monitors to a USB4 or Thunderbolt 4 host. Buyers whose devices only support USB 3.2 or lower will not reach the rated 40Gbps or 240W and should choose a cable matched to their hardware's capabilities.
