What this cable does

The SMUGDESK USB4 cable is a 3.3 ft USB-C to USB-C lead built to the USB4 Gen 3x2 standard. It carries up to 40 Gbps of bi-directional data, delivers up to 240 W of power at 48 V, and drives a single 8K display at 60 Hz or dual 4K displays at 60 Hz when the host and monitor support DP Alternate Mode.

Who it suits and who it doesn't

It suits users who need the full 40 Gbps link between USB4 or Thunderbolt 3 and 4 ports, and who want 240 W charging for high-draw laptops or power banks. It is not for buyers who only have USB 2.0 or 3.0 ports and will not benefit from the higher throughput, nor for setups that require a USB-A connector or a longer reach than 3.3 ft.

The spec that decides fit

The decisive figure is the 40 Gbps USB4 Gen 3x2 data rate combined with 240 W Extended Power Range delivery; if your devices and charger both support that profile you get the maximum speed and power, otherwise the cable simply falls back to the lower standard the port allows.
