USB C Cable 6FT 3Pack - 4K@60Hz, 20Gbps Data, 100W PD Charging

In this review the LDLrui USB C Cable 6ft 3-pack is evaluated for users who need a longer, durable USB-C solution for charging, data and display. The biggest reason to consider these cables is their combination of 20Gbps data transfer potential and 100W PD charging in a braided 6 ft length, making them useful for mobile professionals who move between desks and monitors. Performance will depend on connected devices, but for compatible laptops, phones and monitors these cables offer noticeably faster transfers and more flexibility than typical short charger cords.

Key Features

• 20Gbps Super Speed Transfer: Moves large photo and video files faster than a 10Gbps cable for quicker backups and SSD transfers when both ends support the higher rate.
• 4K@60Hz Video & Audio: Supports DP Alt Mode on compatible USB-C ports to drive an external display up to 4K UHD at 60Hz for clear video and smoother motion.
• 100W PD Fast Charge: E-marker support enables up to 5A and 100 watts so it can charge laptops and tablets at full speed while providing extra reach with a 6 ft length.
• Durable Braided Construction: Nylon braid, gold-plated plugs and reinforced connectors improve longevity and withstand frequent plugging and flexing.
• Wide Compatibility: Works with many current phones, tablets and laptops that use USB-C, including supported MacBook and Galaxy models when ports provide required features.

Who It's For

The LDLrui 6 ft USB C cable pack is best for users who need longer reach than a typical short charger provides and want a cable that can handle both fast charging and high-speed file transfers. Photographers, content creators and laptop users who move between desks and external monitors will appreciate the braided durability and 100W PD support.

It is not ideal for users whose devices do not support DP Alt Mode for video output or for anyone expecting the full 20Gbps at 6 ft with devices or ports that cannot deliver Thunderbolt-level throughput; in those cases shorter or certified Thunderbolt cables or device-specific adapters may be a better choice.

Pros & Cons

Pros

• High theoretical 20Gbps transfer rate for compatible device pairs, improving large file moves.
• Supports 4K@60Hz on devices with DP Alt Mode, useful for external monitor setups.
• Robust build with braided jacket and reinforced connectors for long-term use.
• Includes three 6 ft cables, offering value and spare cables for multiple locations.

Cons

• Actual data speeds drop with length and depend on device ports, so 6 ft may not reach full 20Gbps in many setups.
• Video output only works when the device USB-C port supports DP Alt Mode; some tablets and phones lack that feature.

Our Verdict

The LDLrui USB C 6 ft 3-pack is a strong value for users who need longer cables that combine fast data, high-watt charging and occasional 4K display support.

Frequently Asked Questions

Will these cables charge a laptop at full speed?
Yes, they support up to 100W PD (5A) when used with a compatible charger and device that accept that power level.

Can I use these for 4K monitor output?
Yes, but only if the host device USB-C port supports DP Alt Mode; some tablets and phones do not provide video over USB-C.

Do these cables always reach 20Gbps?
No, the 20Gbps rate is possible with compatible Thunderbolt 3 ports and devices; longer cable length and non-Thunderbolt ports will reduce achievable speeds.
