Silkland 80Gbps USB4 cable 3m with 240W PD for laptops

This 3 metre Thunderbolt 5-capable cable from Silkland connects high-performance laptops and peripherals while handling demanding video and power needs. It delivers very fast bidirectional data transfers and high single-direction video bandwidth, useful for video editing rigs, docking setups and external SSD workflows.

Key Points

The cable supports bidirectional transfer up to 80Gbps at 6200 MB/s, which helps move large media files and project folders more quickly, according to the manufacturer. For one-way video streams the Bandwidth Boost raises throughput to 120Gbps, enabling multi‑display setups such as dual 8K or dual 6K at 60Hz and triple 4K at 144Hz. 📷

A high‑power PD3.1 profile allows up to 240W charging, which makes it suitable for power-hungry laptops and mobile workstations. The integrated E‑Marker chip negotiates current with connected devices to help protect batteries and manage thermal behaviour. 🔋

Build quality focuses on durability and signal integrity. The jacket uses a 48‑strand braid with tin plating for EMI resistance, and the aluminium shell improves heat dissipation. The rounded, slim connector shells are designed to fit with cases and avoid blockages.

Usage Recommendations

For desktop editing suites and docking stations, use this cable to link a MacBook M4 Pro or Pro Max, Mac mini M4, or high-speed PSSD to a monitor array or eGPU. When pushing dual 8K displays or high refresh single-panel setups, confirm that the host and displays support the corresponding DisplayPort 2.1 profiles to get the rated resolutions and refresh rates. 🎬

Consider that maximum rates for video and data may depend on the capabilities of the connected devices and their ports, and real-world speeds can vary according to configuration, according to the manufacturer. Also be aware that while the cable is backwards compatible with Thunderbolt 4 and earlier USB-C standards, not all legacy ports will allow the highest bandwidth or full 240W charging.
