This cable makes connecting devices simple and fast, whether it's for charging, transferring large content, or connecting to a monitor. USB4 Gen 3x2 enables speeds of up to 40 Gbit/s, which in practice means almost instant transfer of videos, photos, or other large files - useful for work, school, or entertainment.

Key product features

⚖️ Compare features with other products of your choice

In addition to the transfer speed, it also stands out in practice for its robust video transmission with built-in support for DisplayPort 2.1, which allows you to connect to monitors and TVs with a USB-C connector without the need for additional adapters. With support for Power Delivery up to 100 W, the cable is suitable for charging modern laptops or other devices that require more power. This means that you can easily manage both data transfer and charging and image transfer with one cable.

A cable less than 1m long is much more convenient for portable solutions – less tangles and easier to use in limited spaces, such as in meetings, in the classroom or while working on the go. Since only one cable is included in the package, it is simple to use and does not require the hassle of searching for additional cables. USB-C connectors on both ends allow direct connection to the latest equipment without the need for converters.

It is important to know

Before purchasing this data cable, it is worth considering whether its features meet your needs in terms of transfer speed, cable length and supported standard. The key to choosing is always the right connection and confirming that the cable actually provides all the functions you expect from a modern USB-C cable. Pay special attention to when a shorter cable is an advantage and when it might be a limitation.

• The 0.5 m cable is very practical for use with portable batteries (power banks), on a work desk or in a car where you don't want excess length.
• The advanced USB4 Gen 3x2 standard and support for very fast data transfer (up to 40 Gbit/s) means it is suitable for the latest devices, but the real usability of this speed also depends on the capabilities of your device or charger.
• The cable supports USB-C to USB-C, which is compatible with most modern devices, but will not be suitable for older devices with Micro USB, Mini USB, or Lightning connectors.
• When charging and transferring images via the DisplayPort standard, it is worth checking in advance whether your device supports this function.

In practice

🟢 Fast charging of modern devices

The cable supports Power Delivery up to 100 W and a USB-C connection, which is very suitable for fast charging of phones, tablets, or even some laptops with a USB-C port.

🟢 Fast data transfer between devices

Thanks to USB4 support and speeds of up to 40 Gbit/s, it is a great choice for transferring larger files, backing up, or connecting to external drives and devices that support such speeds.

🟡 Connection over longer distances (remote sockets)

Due to its shorter length (0.5 m), it is practical for mobile use, but less suitable if you need a longer range - for example, for charging a device at a greater distance from a socket.

🔴 Connection to older devices with Micro USB or Lightning

The cable is not intended to connect devices that do not have a USB-C port, so it is not suitable for older phones, music players, or accessories without a USB-C port.
