240W Thunderbolt 4 Cable 15 ft - 20Gbps 5K/4K@60Hz PD Fast Charging

Our review of the 240W Thunderbolt 4 Cable 15 ft looks at who benefits most from a long, high-power USB-C link and why the cable stands out for charging and video. This cable is aimed at users who need a single, durable 15 ft connection that can carry high-wattage power delivery and display output, such as laptop owners connecting docks, external drives, eGPUs or 4K/5K monitors. The biggest reason to consider it is the combination of up to 240W PD fast charging and support for 5K / 4K@60Hz video over a single cable, which simplifies multi-device setups where distance and power matter.

It may not be the best choice for users who do not need 15 ft length or who require the absolute maximum Thunderbolt 4 bandwidth in every scenario, since real-world compatibility can vary by peripheral. Buyers should verify that their devices and chargers support the stated PD and video modes to achieve peak performance.
