Description
This is a multifunctional, high-performance USB-C extension cable that combines audio and video output, data transfer, and fast charging functions, and offers a variety of size options to effectively solve problems such as desktop clutter, wear and tear on device USB-C ports, and insufficient length of original cables.
UHD 8K Video & Audio Output: Connect your laptop to a larger or portable display via a USB C extender cable with output resolutions up to 8K@30 Hz, 4K@144 Hz/60 Hz for a superior visual experience! (Note: Please make sure the paired input and output devices have Type-C DP-ALT-Mode)
20Gbps Data Transfer: The USBC extension cable uses the USB-C 3.2 Gen 2x2 standard, which is twice as fast as USB 3.1 for fast transfers of HD movies and more, with 10GB files backed up in less than 10 seconds.(Note: To ensure full-speed transfer, the total length when extended should not exceed 10 feet. If a longer cable is required, please purchase the 10-foot or 16-foot models.)
240W 48V/5A Fast Charging: The USB-C male to USB-C female cable adopts PD 3.1 charging protocol, and is also backward compatible with 180 W/140 W/60 W/45 W/36 W/27 W/15 W and so on, which allows you to enjoy no longer bound by the distance, and you can also charge fast while lying on the sofa.
Enhanced design: the core is filled with tensile steel wires to increase overall mechanical strength; the aluminium housing ensures efficient heat dissipation; the 24K gold-plated plug protects against oxidation; and the 48-strand nylon braid technology provides 3 times the protection against tangling and ensures superior strength and long-lasting durability.
Wide range of applications: compatible with Thunderbolt 5, Thunderbolt 4, USB4, USB 3.2, and USB 3.0. Suitable for USB Type-C interface monitors, portable displays, smartphones and laptops, USB-C hub docks, MagSafe chargers and other peripherals. Such as MacBook, iPad, Pixel tablets, iPhone 16/15, Galaxy S25, Switch, iMac Pro, Surface Go, PSVR2 accessories and more.
Note: 1. This type C extension cable does not work with any Thunderbolt 3 docking stations and hubs with active functions; 2. If you experience problems when connecting to USB 2.0 devices (such as a mouse or keyboard), flip the female connector on the extension cable.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $1 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for ZIKNYDO products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
