Silkland S3402 USB4 Cable for Thunderbolt 5, 80Gbps, 240W, 1.6 ft

At 1.6 feet, the Silkland S3402 keeps a USB-C connection close to a laptop, dock, or drive, making it a practical fit for a compact desk setup. Its short format helps keep nearby connections together rather than leaving extra cable across the workspace.

With up to 80Gbps bidirectional data transfer and 120Gbps display bandwidth, this USB4 cable is designed for demanding data and display connections. Actual data speed depends on the connected device.

It also supports up to 240W charging with PD 3.1. An E-Marker chip, braided nylon exterior, aluminum shell, and triple shielding round out a cable built for charging, display, and storage setups.

Getting the most from it

Use the cable to connect a compatible laptop to an SSD, dock, or USB-C monitor, or to charge a compatible device. Its 80Gbps data capability suits setups where high-bandwidth transfers matter, while 120Gbps display bandwidth supports configurations such as dual 8K/6K displays or triple 4K displays at 144Hz. The listed display capabilities also include 16K resolution and 4K at 540Hz, the connected devices need to support the chosen display mode.

For a laptop connection that handles data, display bandwidth, and power, this brings several cable functions together in one compact run. Up to 240W charging supports power-hungry devices, and backward compatibility with 60W, 100W, and 140W charging levels adds flexibility for compatible equipment.

Pros

The combination of high-speed data, display bandwidth, and charging makes the S3402 useful for a dock-centered workstation or a direct connection to an external SSD. Thunderbolt 5, Thunderbolt 4, Thunderbolt 3, USB4, and USB 3.2 compatibility gives it a role across different USB-C setups. The slim shell is designed to fit around phone cases, while the 48-strand braided nylon exterior helps keep the cable manageable in regular use.

Buyers often highlight the cable’s build, data speed, and reliability, and some mention using it with external hard drives. Those comments make its short length especially relevant for a tidy connection between nearby equipment.

What to know

The connectors are male-to-male USB-C, and the cable is listed for indoor use. For display or charging setups, confirm that the connected devices support the mode and power level you intend to use, the cable’s capabilities work in conjunction with device support. The 240W rating is the maximum, with charging also supporting PD 3.1 and backward-compatible power levels.

Customer feedback on connectivity is mixed: while many buyers report good connections, some mention loose connections or compatibility concerns with 6K monitors. This is useful context when selecting a cable for a monitor-specific setup. Compared with choosing a cable focused on just one task, the S3402 combines data, display, and charging capabilities in one short USB-C cable.

Before you decide

What devices is the S3402 designed to connect? It is listed for Thunderbolt 5, Thunderbolt 4, Thunderbolt 3, USB4, and USB 3.2 connections, with compatible devices including laptops, SSDs, docks, monitors, smartphones, iPads, and VR headsets. The specific capabilities depend on the connected equipment.

Can it charge a laptop? Yes. It supports up to 240W with PD 3.1 and backward-compatible 60W, 100W, and 140W charging levels. The device and charger determine the power used.

What display setups does it support? Its listed display bandwidth is 120Gbps, with support described for dual 8K/6K or triple 4K at 144Hz, as well as 16K resolution and 4K at 540Hz. The display configuration must also be supported by the connected devices.

When it makes sense

Choose this cable when nearby USB-C equipment needs a compact connection for fast data, high-bandwidth display use, or charging. Its 1.6-foot length suits laptop-and-dock desks and connections to external drives, while the combination of up to 80Gbps data, 120Gbps display bandwidth, and 240W charging makes it a versatile cable for compatible setups.
