RIIEYOCA 100W USB-C Extension Cable (Short) – 40Gbps data, PD fast charging and 8K@60Hz video support
Product description
What it’s for
A short USB-C extension cable sounds like a small thing until you actually need it. When your USB‑C charger, dock or device port is just a bit too far away, a proper extension saves you from awkward cable stretching or moving gear around.
This RIIEYOCA 100W USB‑C extension is built for both everyday charging and higher-speed connection needs, with the added promise of fast data transfer and video output support. That makes it the kind of cable you pick when you want one “fix” that covers more than just charging.
Key features that matter in day-to-day use
On paper, the standout items are charging power (up to 100W with USB Power Delivery / PD), a quoted high-speed data figure (40Gbps), and support for high-resolution display output (up to 8K@60Hz UHD, with compatibility mentioned for 4K@120Hz and other common modes).
For many people, the practical impact is fairly straightforward: - With PD support and an included E-marker chip, the cable is designed to identify the charging requirements of the connected device rather than relying on a “one size fits all” approach. - The flexible FPC cable design is there for comfort and handling—less fuss when you’re routing cables behind a desk, in a small bag, or around a setup.
It’s also positioned as a short extension rather than a long run, so it’s aimed at closing that small distance gap.
What stands out (and what to be a bit cautious about)
The strong selling points are exactly what you’d want from an extension that’s meant to do more than basic charging: PD up to 100W, high transfer speed, and support for 8K video output.
That said, a quick limitation to keep in mind: video and very high charging/data performance depend quite a lot on what you plug it into. Even if the cable is rated for 8K@60Hz and high transfer speeds, the source device and display/dock also need to support those modes. If your goal is reliable daily video at the highest setting, it’s worth checking device compatibility before assuming you’ll always hit the top numbers.
Everyday use examples
Picture a common setup: your laptop charger sits on a shelf or wall socket, but your laptop is on a desk at an angle. Instead of pushing the laptop cable connection awkwardly to one side, the extension gives you a bit more reach and cleaner routing.
Or, think about a workstation with a USB‑C hub/dock where the dock port sits at the back of your desk. A short extension can reduce strain on the hub’s USB‑C port and make it easier to connect and disconnect without fighting tight cable runs.
For charging, the PD and E-marker approach is relevant if you’re using higher-power chargers—rather than the cable just passively passing power, it’s designed to help align with the device’s needs.
Who it suits (and who should look elsewhere)
It makes sense if you: - need a short USB‑C extension to solve insufficient distance between a device and charger/dock - want one cable that can cover fast charging (PD up to 100W) rather than treating charging and data as separate problems - care about maintaining support for higher-end video output rather than downgrading to “charging-only” style extensions
It may not be the best match if you: - only need charging at low power and you’re happy with a simpler, cheaper extension (you might not be using the cable’s strengths) - plan to rely on the cable alone for top-end 8K/very-high refresh behaviour without checking whether your specific laptop/dock/display can actually deliver those modes through a chain

Mini FAQ
Does a USB‑C extension affect charging speed?
It can, depending on the devices involved and the cable’s ability to support the power profile you’re using. This one is designed for PD fast charging up to 100W and includes an E‑marker chip for identifying charging power needs.
Will I get 8K video through this cable?
The cable is described as supporting 8K UHD display output up to 8K@60Hz, but actual performance depends on the connected source and display/dock supporting those modes.
Is it suitable for office desks and cable routing?
Yes—because it’s a short extension and the cable is described as flexible and bendable, it’s aimed at everyday routing where you want less strain and less awkward movement.
The cable’s speed rating sounds high—do I need it?
If you’re mainly charging, you probably won’t notice the difference. If you transfer large files or you’re using a USB‑C setup where data speed matters, the 40Gbps claim is the point.
Should you buy it?
A solid pick if you need a short USB‑C extension to bridge a small distance gap and you want to keep support for higher-power charging (PD up to 100W), fast data transfer (rated 40Gbps), and high-resolution video output.
However, if your setup is basic or you’re not using higher charging/video/data features, you might be paying for headroom you won’t use. And if your main priority is top-end 8K behaviour, it’s worth double-checking that your devices (source + display/dock) can actually make use of those supported modes through an extension.
