RIIEYOCA 14cm USB C to C 40Gbps Cable: 8K60, PD 240W, 90° Short Reach
Product description
Introduction
The RIIEYOCA USB C to C cable is a compact, 14 cm (5.5 in) USB Type‑C to USB Type‑C lead designed for high‑speed data transfer and fast charging. On the paper spec, it supports USB4 with up to 40Gbps, 8K60Hz video output and 4K120Hz screen mirroring, along with PD charging up to 240W. The built‑in E‑Marker chip helps identify the charger’s power needs, which is useful for safety and efficiency when paired with phones, power banks or external SSDs.
What it’s for
This cable is aimed at users who want a short, reliable link for high‑performance devices in mobility scenarios. If you regularly connect a laptop or tablet to an external display, or you need rapid data transfer to an external SSD while on the go, the 14 cm form factor can reduce cable clutter in bags or work setups. It is particularly handy when you use a mobile power bank or compact dock where a longer lead would get in the way.
How it performs
On paper, the cable trades length for capability. Data throughput up to 40Gbps suggests very fast transfers—think moving several gigabytes in seconds rather than minutes. The 8K60Hz and 4K120Hz capabilities imply strong video pass‑through for external displays, though actual performance depends on the host device, display, and driver support. The PD 240W support indicates it can handle substantial charging power when compatible devices are involved, with the E‑Marker chip adding a layer of smart power negotiation. Note that real‑world results depend on the devices you pair it with and the PD profiles they support.
What stands out
- Ultra‑high data rate on a short, portable cable. The 14 cm length reduces cable clutter while preserving performance.
- 90° USB‑C to USB‑C design helps in tight spaces and when devices are flush against a surface.
- Built‑in E‑Marker for power negotiation, aligning charging power with device needs for safer charging.
- Broad compatibility with phones, power banks and SSDs that use USB‑C.
Where it may fall short
- The short length, while convenient, limits use cases that require longer reach or greater flexibility with large setups.
- Real‑world video output at 8K60Hz and high data throughput will depend on the source device’s capabilities and USB‑C implementation, not all devices will achieve peak 40Gbps or 8K60Hz consistently.
- The kit description does not specify additional features such as braided jacket or reinforced strain relief beyond the “bend resistant” claim, so durability under heavy daily wear should be considered in context.
Who it’s for
- Users who need a compact, high‑speed USB‑C to USB‑C cable for on‑the‑go data transfer and charging between compatible devices.
- People using external SSDs or mobile power banks where a longer lead would be inconvenient.
- Those who value smart power negotiation (E‑Marker) to support safe charging at higher wattage when available.
Who it isn’t for
- If you require a longer reach for a desk‑based workstation or want to run multiple peripherals from a single hub, a longer cable or a different layout might be more practical.
- If your devices do not support high‑speed USB4/PD profiles, you won’t reap the full benefit of the claimed performance.
Before you buy: what to check
- Confirm your devices support USB4 and 8K60Hz/4K120Hz output to get close to the referenced video capabilities.
- Check the PD profile your charger and device negotiate, ensure your charger can supply up to 240W if you intend to use high wattage charging.
- Consider the 14 cm length in your setup: does it help reduce clutter or does it limit placement options?
Practical usage example
Imagine you’re at a coffee shop with a compact ultrabook and an external SSD. You connect the RIIEYOCA cable to the SSD for rapid file transfers and to a display for a presentation via HDMI/DisplayPort route, while the same short lead keeps the power bank tucked away in a bag pocket. It’s small enough to carry without snagging on zippers and still supports quick PD charging when your device needs it.
Tech specs (Summary)
- Cable type: USB C to C, 14 cm length
- Data speed: up to 40Gbps (USB4)
- Video output: supports 8K@60Hz and 4K@120Hz
- Power: PD up to 240W (E‑Marker chip integrated)
- Construction: flexible FPC wire, bend resistant, short and portable
Final verdict
Final verdict: Worth considering if you prioritise a very short, high‑speed USB‑C link for mobile setups, where reducing cable bulk is important and your devices support the high end of USB4/PD specs. It may not be the best option if you need a longer cable for a fixed workstation or if you rely on devices that don’t support the full USB4/PD capabilities described.
FAQ
- What does the E‑Marker do? It helps negotiate charging power between the charger and the device for safe, efficient charging.
- Can I use this with a laptop dock? If the dock and laptop support USB4 with high wattage PD and the required video modes, yes, but real‑world results depend on the devices.
- Is 14 cm enough for daily use? For portable scenarios and compact desks, yes, for more spread‑out setups, a longer cable might be more versatile.
Is it worth it?
It makes sense if you value a compact, high‑speed link for on‑the‑go use and you know your devices can exploit USB4 speeds and PD up to 240W.
