CalDigit TS4 Overview

From Manufacturer

Whether you are a business professional, photographer, or graphic designer, you can turn your desktop into a full-fledged workstation with the CalDigit TS4 Thunderbolt 4 18-in-1 Hub. When combined with a Thunderbolt 4 compatible notebook or PC, the TS4 expands the utility of your device with ample ports and enhanced data transfer speeds for a streamlined desktop setup.

A single Thunderbolt 4 host connection gives you two additional Thunderbolt 4 ports, offering data transfer speeds up to 40 Gb/s and daisy-chaining technology so you can connect multiple devices such as storage drive arrays, displays, and more. Support a wide range of peripherals with three USB-C and five USB-A ports, all sporting a USB 3.2 Gen 2 interface for enhanced data-transfer speeds and quick file migration. Photographers can easily upload files using the microSD and SD UHS-II ports built directly into the front of the device, alleviating the need for adapters. Additional multimedia functionality s provided via the DisplayPort 1.4 output, the 3.5mm front access combo audio jack, and two 3.5mm rear line-in and line-out jacks.

DisplayPort Output
The TB4 can support displays up to 8K resolution when only a single display is connected. Otherwise, the TB4 can support dual 4K 60 Hz displays on select devices such as Intel-based Macs, Windows operating systems, and Chrome OS. Original M1 based Macs do not support dual displays.
Power Delivery
  • Thunderbolt 4/USB4 Host Port: Up to 98W (5V, 9V, 15V/3A, 20V/4.9A)
  • Each Downstream Thunderbolt 4/USB4 Port: 15W (5V/3A)
  • Front 20W USB-C Port: 20W (5V/3A, 9V/2.22A)
  • Remaining USB-C Ports: 7.5W (5V/1.5A)
  • USB-A Ports: 7.5W (5V/1.5A)
Internet Connection
If you do not have access to your Wi-Fi connection or simply prefer a wired connection, a 2.5 Gigabit Ethernet port is available so you can quickly download documents, watch your favorite media, or even take part in conference calls with ease.
System Requirements
Thunderbolt 4 is compatible with a range of operating systems running macOS 11.4 (Big Sur) or above as well as Windows 10 (20H2) or later. While Thunderbolt 4 is the optimal choice for greater system efficiency, Thunderbolt 4 is also compatible with Thunderbolt 3 and USB 4.0 Type-C devices including select Chromebooks, iPad Pro, iPad Air, iPad Mini, and Windows Tablets with reduced performance.

CalDigit TS4 with linux

By Douglas
Rated 5 out of 5

My brand new TS4 is certainly living up to my expectations. I am connecting to very new System76 Pangolin Pro. Mine is an AMD powered laptop. I use 1 DisplayPort and 1 usb-c to hdmi to connect to my displays, a wired Ethernet connection and a couple Samsung external drives. Everything works better than I could have predicted. I should mention that I am using thr integrated AMD graphics to further simplify the environment. And it’s a single usb-c cable connection. It was a flawless connection

Necessary & Perfect

Game changer! Instantly turned my laptop into a full workstation. Love the 18 ports, 98W charging, dual display support, 2.5GbE, and insanely fast data throughput. If you have multiple devices to plug in all at once (teradrives, scanner, monitor, etc) and need each to operate simultaneously with accuracy and speed, BUY this! It has saved me so much time and greatly reduced tech issues I had prior.
