lalasis CY018-3 USB-C Cable, 3m, 20Gbps, 240W and 5K Video

Connect a USB-C laptop to a compatible monitor or keep a phone within reach of a charger with the 3m lalasis CY018-3 cable. Its extra length gives you more freedom to arrange your devices on a desk or in a home office.

The USB 3.2 Gen 2x2 connection supports data transfer rates of up to 20Gbps, making large file transfers and backups more convenient when both connected devices support the required standard.

It also supports charging up to 240W and USB-C video output up to 5K at 60Hz or 4K at 144Hz. One cable can therefore serve charging, data and display needs, with the right capabilities on the connected devices.

What matters most

This USB-C to USB-C cable brings together three useful functions: high-speed data, high-power charging and video output. For transferring files, it supports up to 20Gbps under the USB 3.2 Gen 2x2 standard. To reach that rate, both ends must connect to devices that support USB 3.2 or a higher standard, such as USB 4 or Thunderbolt 3/4.

For charging, PD 3.1 and QC 4.0+ support allow power delivery up to 240W (48V/5A), with an integrated e-marker chip managing current. The charging rate depends on the connected device and power source. For a desk setup, the cable can also carry video from a USB-C laptop to a USB-C monitor at up to 5K at 60Hz or 4K at 144Hz, both devices need to support video over USB-C, including DP Alt Mode.

How to use it

Connect the USB-C plugs to your devices, charger or display as needed. The reversible USB-C connectors make plugging in straightforward, while the 3m length helps when sockets, screens and devices are not right beside one another. For the advertised data rate or display modes, check that the relevant connected devices support those functions. The cable is listed for use with laptops, monitors, PCs and smartphones, including USB-C iPhone 15, 16 and 17 models.

Everyday use

At a workstation, use the cable to connect a compatible laptop to a USB-C monitor, transfer files between supported devices or charge equipment from a suitable power source. At home, its length can make it easier to place a phone or tablet where you want it while charging. You can choose it as a multi-purpose USB-C cable rather than a shorter cable intended mainly for charging or a data-only lead.

A braided nylon covering is designed to help resist tangling, and the cable has a stated 20,000-cycle bending test. Its aluminium-alloy housing adds a sturdy finish at the connectors. These details suit regular handling at a desk or when moving between work and home setups.

Practical questions

Will it transfer data at 20Gbps with any USB-C device? Both connected devices need to support USB 3.2 or a higher standard, such as USB 4 or Thunderbolt 3/4, to achieve the stated rate. The cable is also backward compatible with USB 3.1, 3.0 and 2.0.

Can it connect a laptop to a USB-C monitor? Yes, for video output the connected USB-C device must support DP Alt Mode. The stated output is up to 5K at 60Hz or 4K at 144Hz.

What is needed for 240W charging? The cable supports charging up to 240W with PD 3.1 or QC 4.0+, but the charger and device must also support the relevant charging capability.

Should you buy it?

The lalasis CY018-3 is suited to anyone looking for one 3m USB-C cable for compatible charging, fast file transfers and USB-C display connections. Its combination of up to 240W charging, 20Gbps data and high-resolution video support makes it a practical fit for a desk setup where a single cable needs to handle more than one task.
