- Supports Thunderbolt™ 3 20Gbps of bandwidth with compatible systems and accessories and all USB generations; USB 1.1, 2.0, 3.0 and USB 3.1 (Gen 1 only) over USB Type-C
- Single 4K@60Hz video output or dual 1080P@60Hz outputs
- Daisy chain up to 6 Thunderbolt devices including docking stations, external graphics cards, and displays
- Wire gauge and electronic marking support up to 5A charging via USB-IF Power Delivery charging standard (5V-20V, 100W max)
- Thunderbolt 3 peer-to-peer 10Gbit networking
Note1: This cable is incompatible with Qualcomm Quick Charge and other (non USB-IF Power Delivery) “Fast Charge” technologies.
Note2: 20Gbps speed cables are NOT suitable for eGPU and dual 4K display scenarios. If you wanted to connect eGPU, we would recommend using a 40Gbps speed cable instead.
Thunderbolt™ 3 brings data transfers at speeds up to 20Gbps over USB-C, enabling a superset of standard USB-C to truly enable one compact port that does it all – delivering the fastest, most versatile connection to any dock, display, or data device. For the first time, one port can connect numerous Thunderbolt devices, any display, and billions of USB devices (additional adapters may be required). Thunderbolt 3 cables are primarily used for connecting docking stations, high performance data storage solutions, peer-to-peer networking, and more.
The Plugable TBT3-20G2M cable is first and foremost designed as a Thunderbolt 3 cable but it is also a universal USB-C cable for use with USB-C computers, phones, tablets, chargers, docking stations, accessories, and more. It supports all USB-C cable features, including USB 3.0 and USB 2.0 data lines, wire gauge supporting up to 3A charging via USB-IF Power Delivery charging standard (5V-20V, 100W max), and support for reporting its capabilities as an electronically marked cable. Please note for USB-C usage this cable is limited to USB 3.1 Gen 1.
Because the cable is designed for Thunderbolt 3, it is also capable of supporting data transfer speeds twice as fast as standard USB-C cables. The available 20Gbps bandwidth allows for dual 1080P@60Hz video outputs (or a single 4K@60Hz output) and up to 5A/100W charging capabilities when used with compatible systems and Thunderbolt 3 accessories.
Q: What are some common uses for this cable?
A: Thunderbolt 3 cables are primarily used for connecting Thunderbolt 3 docking stations, high performance data storage solutions, peer-to-peer networking, and more. Other common scenarios are connecting a standard USB-C device to a USB-C Power Delivery charger or connecting a USB-C host to a USB-C peripheral.
Q: Can I use this cable for charging my cell phone or tablet?
A: Yes! We’ve test with our Google/LG Nexus 5X and Nokia Lumia 950 and have had good results. A note to users with the Nexus 5X, if your phone does not charge using our cable in combination with your stock Nexus 5X LG charger, the charger may be defective and you should contact LG Support.
Q: Why does the listing state that this cable is incompatible with Qualcomm Quick Charge?
A: Proprietary charging techniques such as Qualcomm Quick Charge work outside of the USB-IF Power Delivery specification (by utilizing the USB data lines rather than the CC line), and therefor are not supported nor recommended for use with e-marked cables.
Q: The cable feels loose when connected to my device. Either movement side to side, or when plugging in or unplugging.
A: The TBT3-20G2M cable is designed to meet the requirements of Thunderbolt 3 and as such it’s connector should be universal for nearly any USB-C device. However, not all USB devices are manufactured to the same standards. Normally one should expect when connecting the cable to have a defined “click” when plugging the cable in. The cable should only require medium (“normal”) force to unplug, and the side to side movement should only be a few degrees.
