- Long-Distance Without Signal Loss – True Coaxial Core Unlike ordinary twisted-pair extension cables that struggle at 10 feet, this coaxial USB C extension cable is engineered to maintain full 40Gbps bandwidth, 8K video integrity, and 240W power delivery even at 3 meters (10FT). The coaxial design dramatically reduces electromagnetic interference and signal reflection – so your extended connection feels exactly like a direct plug. Perfect for: extending a Thunderbolt 4/3 dock to your desk, connecting an eGPU in a remote corner, or setting up a VR play area with zero lag.
- 40Gbps Ultra‑Fast Data – Real World Speed for Thunderbolt & USB4 Designed to work seamlessly with Thunderbolt 4, Thunderbolt 3, and USB4 devices, this 3‑meter extender delivers 40Gbps bidirectional transfer. Move an 8K movie in seconds, edit RAW photos directly from an external SSD, or run a high‑resolution webcam without stutter. Fully backward compatible with USB 3.2 / 3.0 / 2.0 devices – plug and play. *Works as an extension for Thunderbolt 4/3 cables – keep your expensive Thunderbolt cable at full length while extending the USB‑C side.*
- True 8K Video – No Compression, No Flicker Supports single 8K@60Hz or dual 4K@60Hz displays. The triple‑shielded coaxial construction and gold‑plated contacts preserve every pixel. Perfect for color‑critical work (photo/video editing) or immersive sim racing / flight sim rigs – whether you're connected through a Thunderbolt dock or directly to a USB4 laptop. Note: 8K requires a source and display that both support 8K. For 4K setups, you get crisp, artifact‑free extension up to 10FT.
- 240W PD3.1 Charging – Fast & Safe Over 10 Feet Delivers 240W (48V/5A) to charge a gaming laptop, workstation, or high‑power tablet at full speed – even through a 3‑meter extension. The built‑in E‑Marker chip intelligently negotiates PD3.1 and QC4.0 protocols, preventing over‑current, over‑voltage, and short circuits. Your devices stay cool and safe. Pair with any 240W USB‑C charger or Thunderbolt 4 dock that supports power delivery to reach the full potential.
- Soft & Flexible – Coaxial That Bends Like a Rope Traditional coaxial extension cables are stiff and annoying. Not this one. We use a soft, highly flexible coaxial structure that easily routes behind desks, along floor edges, or inside cable trays. No kinking, no memory effect – it stays where you put it. Passed 15,000+ bend tests with reinforced zinc‑alloy stress relief.
- Why 10ft/3m Matters for Thunderbolt & USB4 Setups Thunderbolt 4/3 dock extension – keep your dock hidden under the desk while devices stay within reach. eGPU (external GPU) – place the eGPU on the floor or across the room without losing 40Gbps bandwidth. VR headset – enough slack to move around without pulling the base station. Conference room – connect a Thunderbolt laptop to a wall‑mounted display or hub. Bedside charging – reach from the wall outlet to your nightstand. Most USB‑C and even Thunderbolt cables lose signal or power beyond 6 feet when extended. This coaxial extender is purpose‑built for real 10‑foot reliability.
- Universal Compatibility – Thunderbolt 4/3, USB4, and All USB‑C Devices Works perfectly with: Thunderbol 4 and Thunderbol 3 devices (docks, eGPUs, SSDs, monitors) USB4 laptops and peripherals USB‑C laptops (PC, Chromebook, M_acBook, etc.) Tablets & smartphones USB‑C hubs / docking stations Portable monitors VR headsets (Oculus Quest / Pico with link cable) Steam Deck, ROG Ally, Nintendo Switch (via dock extension) Plug & play – no driver or adapter needed.
- Built to Last – Even at Full Length Coaxial + triple shielding – rejects RFI/EMI, essential for Thunderbolt’s high bandwidth 24K gold‑plated contacts – corrosion‑free, maximum conductivity Zinc‑alloy connector housing – resists crushing and bending Strain relief tail – prevents internal wire breakage 15,000+ bend cycle tested – outlasts ordinary extensions by years
- Important Note About Thunderbolt Compatibility This cable is not certified by Intel for Thunderbolt, but has been extensively tested to work with most Thunderbolt 4 and Thunderbolt 3 devices at full 40Gbps speeds. It functions as a passive extension for existing Thunderbolt cables – simply connect your Thunderbolt cable to the female end, and the male end to your device. For optimal performance, keep total cable length (Thunderbolt cable + this extender) under 10.3ft (3.15m) when running at 40Gbps. If you need to extend beyond 3.15m total, we recommend using an active Thunderbolt extension or reducing the data rate to 20Gbps.
- Why Choose This Coaxial Thunderbolt‑Ready Extension True coaxial design – no signal drop at 10 feet Full 40Gbps / 8K / 240W – no trade‑offs Works with Thunderbolt 4/3, USB4, and all USB‑C devices Soft and flexible – easy to route
