Green Jiss USB-C Extension Cable 10ft (20Gbps, 4K@60Hz, 240W PD) — Male to Female USB3.2 Gen2 Extender
Product description
The essentials
If you need more reach for a USB-C setup—while still expecting fast data, charging, and even video over the same cable—this Green Jiss USB-C extension is built for that kind of “do it all” job. On paper, it’s a USB3.2 Gen2 extension cable rated for up to 20Gbps, supports video up to 4K@60Hz (or 2K@120Hz), and claims power delivery up to 240W for compatible devices.
That combo is exactly why people look for a USB-C extender in the first place: your laptop/handheld is on one side of the desk, and the hub, monitor, or dock is across the room. A longer connection can help you place gear where it makes sense—without constantly reaching for shorter cables. It’s not perfect for every situation, though. With any USB-C extension, longer runs can affect signal and charging behavior depending on what you connect.
Key takeaways (what matters most)
Where this cable stands out is the “full function” positioning: it’s designed to extend USB-C connections for data transfer, video output, and high-power charging. The heavy-duty, nylon braided jacket is meant to handle daily bending and unplugging, and the connectors are described as corrosion-resistant with reinforced strain relief.
Still, the video and charging claims depend on compatibility. The listing explicitly notes that charging power and video output depend on the connected devices and cables, and that using a USB-C extension means you should pay attention to the cable’s power supply and how longer data lines can degrade performance. So you’re buying a capability set, not a guarantee for every device chain.
Also, there’s an important limitation: Thunderbolt 3/4/5 USB-C port devices are not supported.
What you’ll notice day to day
In real setups, the practical win is simple: you can route your cable neatly and keep your workspace usable. For example, you could plug your USB-C laptop into this extender, then connect a USB-C hub or monitor on the far side of your desk. If your monitor’s USB-C port supports video input/output, you should be able to mirror or extend displays up to the supported resolution.
For charging, the cable is listed as supporting up to 240W power delivery (with backward compatibility with 100W/65W/45W). In other words, if your device and charger support those power levels, this extender is meant to stay in the “fast charging” lane rather than forcing you down to a basic, low-power extension.
One caution: the faster you push data/video/power through an extension chain, the more you’ll notice when something in the chain isn’t fully aligned. The listing also warns that additional connection cables may affect signal/current/transmission speed.

Who it’s for (and who should skip it)
This cable makes sense if you’re trying to extend a USB-C connection for everyday desk use—especially when you want more than just charging. It’s a solid fit if you plan to connect a USB-C hub, dock, or a USB-C TV/monitor for video, and you’re dealing with limited cable length.
It’s also worth considering if you care about build and cable management. The nylon braid, reinforced connector tail, and strain relief are the kind of details that help with frequent unplugging and bending.
It might not be a great match if you’re relying on Thunderbolt 3/4/5 USB-C ports. And if your setup uses multiple extra adapters/cables in series, you may see reduced performance—this extender can’t completely override compatibility and signal loss realities.
Compatibility & requirements
The listing says it’s compatible with a wide range of USB-C devices and accessories, including USB-C hubs, certain wireless charger setups, Switch, PSVR2, iPad Pro, Surface Go, i-Mac Pro, MacBook, ChromeBook Pixel, Dell XPS 13/15, and Galaxy S24/S23/S22.
But for video, you’ll want to double-check your monitor or TV port specifically: it notes that you should make sure the “Port C” and Type C output monitors support video input/output functions.
For charging, don’t assume the 240W number automatically applies to every scenario. Charging power depends on the connected devices and cables, so if your device or charger isn’t capable, you won’t magically get higher wattage.
Is it worth it?
Buy the Green Jiss 10ft USB-C extension if you need extra reach for a USB-C setup and you want one extender that’s designed to carry data, video (up to 4K@60Hz), and high-power charging (up to 240W) for compatible devices. It’s especially compelling if you’re tired of juggling short cables and you want a sturdier connection that’s meant to survive everyday bending.
Skip it if you’re using a Thunderbolt 3/4/5 USB-C port, because the listing says those aren’t supported. Also be cautious if your chain includes multiple additional connectors—since the listing warns performance can drop with longer runs and extra cabling.
In short: it’s a “full function” extender geared toward people who actually use their USB-C ports for more than one job. If your setup aligns, it can save a lot of hassle, if your devices don’t support the needed video/charging behavior, you may end up with less than you hoped.
Mini FAQ
Does it support charging and video at the same time?
The listing presents it as a full-function USB-C extender for both high-power charging and video output, but it also states charging power and video output depend on the connected devices and cables.
Will it work with Thunderbolt 3/4/5 ports?
No. The listing explicitly notes that Thunderbolt 3/4/5 USB-C port devices are not supported.
What video resolution can I expect?
It’s listed as supporting up to 4K@60Hz (and also mentions 2K@120Hz). Actual results depend on your monitor/TV and whether its USB-C port supports video input/output.
How durable is the cable?
The listing claims it passes 400,000+ bending tests and includes molded strain relief, reinforced connector tail, and a braided nylon jacket intended to resist wear and tangling.
Will extra adapters reduce performance?
The listing warns that additional connection cables may affect signal/current/transmission speed, so a simpler chain usually helps.
