The bottom line: this cable combines very high display bandwidth and fast bidirectional data transfer with 240W PD 3.1 charging, so it replaces multiple specialized cords and reduces desktop clutter while delivering stable performance for demanding workflows.

Key Features

• 80Gbps data transfer: Bidirectional 80Gbps throughput moves large project files fast, allowing a 6GB file to transfer in roughly one second for quicker backups and edits.
• 120Gbps display bandwidth: USB4 Version 2.0 enables up to 120Gbps unidirectional video, supporting dual 8K@60Hz or triple 4K@144Hz configurations for multi-monitor editing.
• High-power PD charging: PD 3.1 support delivers up to 240W (48V/5A) with an E-Marker chip for smart current regulation and basic safety protections.
• Durable build: 48-strand braided nylon and an aluminum shell improve abrasion resistance and heat dissipation for long-term reliability.
• Shielded signal integrity: Triple shielding with tin-plated EMI foil, 28AWG oxygen-free copper and rhodium-plated connectors helps maintain stable connections under load.
• Wide compatibility: Works with Thunderbolt 5/4/3, USB4 and USB 3.2 devices so it can connect modern laptops, SSDs, docks and USB-C monitors.

Who It's For

The Silkland cable is aimed at photographers, video editors and designers who run multiple high-resolution displays and move large media files between external SSDs and workstations.
