Ubluker USB C to USB C Cable (USB4 / Thunderbolt 4) 40Gbps 1m, up to 240W PD 3.1

Quick overview

If you’ve ended up with multiple cables for charging, data transfer, and “will it drive my monitor?” moments, this Ubluker USB C to USB C cable is built to cover a lot of those bases from one lead. On paper it targets USB4 with Thunderbolt 4 compatibility, with high bandwidth (40Gbps) and support for DisplayPort alternate mode, alongside USB-C Power Delivery (PD 3.1) for fast charging.

That combination is exactly why people look for a single, higher-spec USB-C cable: one cable you can keep on your desk, in your bag, or connected to a docking setup—without constantly swapping between a charge-only cable and a thicker “video/data” one. That said, it’s still a cable: performance depends heavily on the host device and the way your setup negotiates power and display modes.

The essentials

The standout features listed for this cable are the headline transfer rate (40Gbps), a 24PIN design, and the inclusion of an eMarker. It’s also described as nylon braided, which usually means it’s aimed at everyday handling rather than treating the lead like something you only unbox once.

For video and audio, it references DisplayPort alternate mode and “Thunderbolt alternate mode”, plus “USB C alternate modes”. For data, it mentions broad USB performance support (ranging from older USB speeds up through higher SuperSpeed+ / USB 3.2 and beyond). For charging, it’s specified for PD 3.1, with up to 48V 5A (and a wider set of voltage/current combinations listed up to 240W).

There’s also some extra detail that matters for certain connectivity setups: it references PCIe tunnelling and host-to-host communication. That’s the kind of wording you’ll see when a cable is intended to work in the “dock / eGPU / storage / hub” world, not just charging a phone.

What stands out in everyday use

Where this cable looks strongest is in scenarios that mix needs: charging a laptop while moving files, connecting to a dock for displays, or using it between a device and a hub/monitor where a plain charge lead just wouldn’t cut it.

A practical example: imagine you’re working at a desk with a USB-C dock that also needs video output and power. Using a cable that supports DisplayPort alternate mode and PD (rather than a basic USB-C cable limited to charging) can reduce the usual faff of “charge cable here, display cable there”. In the same way, if you’re transferring large files (the listing calls out large file transfers), the higher stated bandwidth is the sort of thing you’d be buying for—provided your devices negotiate the same capability.

Tech specs (worth checking before you buy)

• Type: USB C to USB C cable
• Name: Ubluker USB4 / Thunderbolt 4 style cable
• Format: 24PIN
• Size: 1m length
• Refresh rate: Not specified (video support is described via alternate mode)
• Processor: Not applicable
• Memory: Not applicable
• Power delivery: PD 3.1
• Max power: up to 240W (listing also includes multiple voltage/current profiles)
• Stated data speed: 40Gbps
• eMarker: Included
• Braiding/material: Nylon braided

It also states “Video, Picture, Audio, Data Sync” and “DisplayPort Alternate Mode” support, plus Thunderbolt alternate mode support for compatible devices.

One limitation to keep in mind: the listing includes lots of “supported” USB speeds and voltage profiles, but the actual result you get will depend on what your specific phone/laptop/dock/monitor can request and negotiate over USB-C.

Key takeaways on compatibility

This cable is clearly aimed at people who want USB-C versatility across devices—phones, tablets, laptops, hubs/docks, and setups that require display output and power delivery. The listing also explicitly calls out a Thunderbolt 4/3 compatibility angle and mentions iPhone/iPad and Galaxy and MacBook/Mac mini/Mac Studio contexts.

Still, compatibility isn’t automatic just because the cable is labelled for a broad set of standards. If your device or your dock doesn’t support the relevant alternate modes (especially for display), you may only get charging and basic data. It’s not a deal-breaker, but it’s worth sanity-checking your exact device ports and what they support.

It makes sense if you already use (or plan to use) USB-C docks/hubs/monitors and you’d like one cable to do power + video + data, rather than maintaining a small “cable kit”.

Pros

• High stated bandwidth (40Gbps) and USB4/Thunderbolt 4 positioning
• PD 3.1 support, with multiple voltage/current combinations listed and up to 240W claimed
• Nylon braided build and eMarker included
• Designed for more than charging: video/audio/data sync, DisplayPort alternate mode, and tunnelling language for advanced setups

When it may not be a great match

This might feel like overkill if you only need a simple replacement charge lead for a phone or you don’t use docks/monitors. Also, if you expect every USB-C connection to “just work” for video, be cautious—alternate modes require support on both ends (device and any connected accessory).

Is it worth it?

Buying it is a sensible move if you want a single USB-C cable that’s built for mixed duties: charging via PD 3.1, plus higher-speed data and the possibility of display output through DisplayPort alternate mode, ideally in dock/hub setups where Thunderbolt-style connectivity matters.

You may want to skip it if your use is strictly charging, or if you’re only ever connecting to accessories that don’t rely on video/data negotiation over USB-C. It’s not that it can’t be used in simple setups—it’s just that the feature set here is aimed at people who will actually make use of it.

Finally, double-check what your devices and dock/monitor support for USB4/Thunderbolt alternate modes and DisplayPort alternate mode, because that’s where the real-world experience will be decided.

FAQ

Will this cable charge my devices?

It’s specified for USB-C Power Delivery (PD 3.1) and lists multiple voltage/current profiles up to a maximum stated power of 240W, so it’s intended for fast charging—though the exact wattage you get depends on your device.

Can it output video to a monitor?

The listing mentions DisplayPort alternate mode and Thunderbolt alternate mode support. If your device and monitor/dock support the same negotiation, video output is the intended use.

Does it work for data transfer and large file moves?

It’s described as supporting data sync and large file transfers, and it lists very high stated bandwidth (40Gbps). Real throughput will still depend on the devices in the chain.

Is the 1m length enough?

For desk use and typical hub/dock setups, 1m is often practical. If you need more reach, you’d generally look for a longer lead, but the listing you provided only specifies 1m.
