This article covers Plugable Thunderbolt 3 ケーブル 40Gpbs 100W 充電対応（80cm.

Overview

The Plugable Thunderbolt 3 Cable (80cm) brings certified 40Gbps performance and 100W power delivery in a compact, everyday-friendly length. It carries official Thunderbolt 3 certification, ensuring reliable high-speed connections for external GPUs, docks, and high-resolution displays. Because it's also a fully functional USB 3.1 Gen2 cable, you can use it with any USB-C device, from smartphones to laptops. The 80cm length is particularly well-suited for desktop setups, offering just enough reach from a laptop to a dock or monitor without creating a mess of excess cable.

Connectivity & Compatibility

This cable works at full Thunderbolt 3 speed with any Thunderbolt 3 host (Mac 2016+ and Windows). It also functions as a USB 3.1 Gen2 cable (up to 10Gbps) on non-Thunderbolt USB-C ports. DisplayPort Alt Mode is supported, enabling direct video output to compatible monitors. Daisy-chaining of up to six Thunderbolt 3 devices is possible, allowing dual 4K @60Hz or single 5K display configurations. Note: non-USB-IF charging protocols such as Qualcomm Quick Charge 3.0 are not supported.

Product Info

Plugable has been selling this cable since around 2019, positioning it in the mid-to-high end of the cable market. The build quality is solid, and the 2-year warranty provides peace of mind. Pricing hovers around $35–$40 (¥5,000–¥6,000 in Japan), making it a more affordable alternative to brand-name Thunderbolt 3 cables from Apple or other OEMs. The package contains only the cable, with no additional adapters or cases.

Best Use Cases

Creative Professionals: If you use a Thunderbolt 3 laptop for video editing or 3D rendering, this cable can connect an eGPU or fast external storage while simultaneously charging the laptop at 100W. One cable does it all. Multi-Monitor Workers: For dual 4K display setups, daisy-chaining monitors via this cable keeps your desk clean and reduces clutter. The 80cm length is ideal for short runs between a laptop and a monitor stand. Future-Proof Buyers: If you currently own only USB-C devices but plan to adopt Thunderbolt 3 peripherals later, this cable works with both. No need to buy a separate cable when you upgrade. Not for Quick Charge 3.0 Users: If your device relies on QC3.0 fast charging, this cable will not provide the fast charging speeds; it only supports USB PD.
