Compatibility Guide
This cable works with any device featuring a USB-C port. It delivers full performance with USB4 PCs, Macs, Thunderbolt 4 laptops, and USB 3.2 Gen 2x2 external drives. It is also compatible with USB 3.2 Gen 1 and USB 2.0 devices, though speeds will be limited by the slower device. Thunderbolt 3 ports are supported and operate at the same 40Gbps maximum.
Ideal Use Cases
- Connecting a USB4 laptop to an external SSD for high-speed data transfer.
- Driving a USB-C monitor at 8K resolution.
- Combining laptop charging and data transfer through a single cable.
- Future-proofing your setup for upcoming USB4 devices.
Upgrade Considerations
USB4 cables are highly backward compatible, so you don't need to replace existing USB-C devices. However, to achieve 40Gbps speeds, both the host and device must support USB4 or Thunderbolt 4. Older USB 3.0 or USB 2.0 devices will bottleneck performance; consider upgrading those devices if speed is critical. For 240W charging, ensure your charger and device support USB PD 3.1.
