deleyCON MK7742 2 m USB-C Cable, 240W PD 3.1, 10 Gbps

Connect a USB-C laptop to a charger at your desk, then use the same cable to transfer files when needed. The deleyCON MK7742 combines charging and data transfer in a 2 m USB-C to USB-C cable, giving you room to set up compatible devices where they are convenient.

With Power Delivery 3.1 support up to 240W and USB 3.2 Gen 2 data speeds up to 10 Gbit/s, it brings high-power charging and quick synchronisation together. Actual charging depends on the connected device and charger.

If your priority is one charging connection, a basic charge-only lead may cover that need, this cable is suited to setups where charging and data access are both useful.

What matters most

The cable supports Power Delivery 3.1 up to 240W (48V / 5A), for use with compatible USB-C chargers and devices. An integrated E-Marker chip manages the power negotiation, helping the connected equipment use an appropriate charging profile. This makes the cable suitable for a range of USB-C devices, from phones and tablets to laptops, when their charging requirements are supported by the charger.

For file transfers, USB 3.2 Gen 2 supports speeds up to 10 Gbit/s. Connect a phone to a computer to synchronise data, or attach an external USB-C drive for access from a laptop. Charging and data transfer can take place at the same time, so one connection can handle both tasks.

The cable has USB-C male connectors at both ends, a nylon outer braid and aluminium connector housings. Reinforced strain relief at the joints is designed to help protect the cable where it flexes during everyday plugging and unplugging. Its black and charcoal grey finish suits a home or work setup.

Usage tips

Use the 2 m length to connect devices positioned a little further apart, such as a laptop on a desk and a nearby charger or external drive. Both the device and charger need USB-C connections for charging, for higher-power charging, they also need to support the relevant Power Delivery capability. The cable can also connect compatible USB-C devices to a car charger.

For a display connection, the product is listed for 4K at 60Hz. The connected devices and their USB-C ports must support the display mode for that setup to work. A USB-C port is also the key requirement for everyday charging and data connections, whether the device is a mobile phone, tablet, computer or external drive.

Everyday use

Keep it with a laptop for a practical two-purpose connection: charge from a suitable USB-C power source during the day, then connect a phone or storage device to transfer files. The 2 m reach can help when the charging point is not immediately beside the device, while the stated 10 Gbit/s data rate supports quick synchronisation of photos, videos and other large files when the connected equipment allows it.

It’s a good fit if you want one cable for compatible USB-C charging and data tasks rather than keeping separate leads for each. The combination is also useful for a shared home or office setup, where a cable may move between a phone, tablet, laptop and external drive. Check the connection type and charging needs of the devices you plan to use it with, both ends of this cable are USB-C.

Practical questions

Which devices can I connect? The cable is intended for devices with USB-C ports, including compatible phones, tablets, laptops, cameras and external drives. Charging and data functions depend on the capabilities of the connected devices.

Can it charge and transfer data at the same time? Yes. It supports simultaneous charging and data transfer, making it useful for connecting a device to a computer while keeping it powered.

What is the maximum charging support? It supports Power Delivery 3.1 up to 240W (48V / 5A). The charger and device must support the required power profile to use it.

Final verdict
