15 Ports of Extreme Connectivity

When it comes to port connectivity, more is definitely more! The Thunderbolt Station 3 Plus offers ultimate connectivity by adding a staggering 15 ports for any application. The options go beyond the conventional, helping Thunderbolt 3 users to not only expand their connectivity but also charge their laptops. The power of Thunderbolt 3 combined with CalDigit’s long history designing docking solutions has resulted in the most powerful Thunderbolt 3 dock available.

USB 3.1 Gen.2

Why would someone need USB 3.1 Gen.2? To put it simply, devices like high-performance SSDs require the full bandwidth of USB 3.1 Gen.2 in order to get full performance. While USB 3.1 Gen.1 ports can provide great performance, a Gen.2 port will get the maximum transfer speeds out of your high-speed storage devices.

SD Card Reader

With the advent of digital media, transferring data from SD cards to computers has become an integral part of any project, especially digital photography and 4K videography. TS3 Plus’ SD card reader supports SD 4.0 and UHS-II speeds with a maximum theoretical throughput of 312MB/s, which means that transferring data from SD, SDHC or SDXC cards will be done in no time. 

Digital Optical Audio (S/PDIF)

When it comes to high-quality audio playback, every audio enthusiast knows the benefits of using the best equipment to retain optimal audio signals in its purest state. The Digital Audio port allows users to connect directly to their amplifier, speakers, or home theatre receiver for a pure digital signal.

Laptop Charging

Thunderbolt™ 3 incorporates power delivery, allowing the TS3 Plus to charge Thunderbolt™ 3 laptops. Mac and PC users can put their laptop charger away and power their laptop through a single Thunderbolt™ 3 cable. The 87W power delivery will charge laptops in no time.

5K or Dual 4K Displays

The TS3 Plus’ extreme connectivity is not just confined to data as it can also achieve extreme visual fidelity. Users have the option to connect dual extended 4K 60Hz monitors or a single 5K 60Hz monitor. The versatile DisplayPort connector can be used to connect to any monitor through the use of an active DisplayPort cable/adapter.

If you needed to convert DisplayPort (DP) from the Dock to HDMI, DVI, or VGA output to your existing monitors without a DisplayPort Input, please make sure you are using an ACTIVE DisplayPort adapter. Regular Passive adapter will not work. An ACTIVE DisplayPort adapters has a chipset inside the adapter to properly convert to DP++ signal.

* Some Windows Thunderbolt 3 laptops only support one DisplayPort stream from Thunderbolt 3 port, as the result, such laptops can output up to a single 4K 60Hz or dual 4K 30Hz monitors. Please verify the Thunderbolt 3 port capability with your Windows laptop provider.
** Intel-based Macs can support up to 2 external monitors from each Thunderbolt 3 bus. Apple M1/M2 Macs, such as the MacBook Pro 13”, MacBook Air, and Mac mini, only support 1 external display though their Thunderbolt/USB4 bus. Apple M1 Pro & M1 Max Macs support dual displays though the TS3 Plus.


*Some Windows PC manufacturers have decided to restrict functionality on their Thunderbolt 3 and USB-C ports such as charging and monitor compatibility. Check to see if your PC supports external monitors.
**Some refresh rates require DP 1.4 HBR3 and DSC 1.2 support from host GPU and monitor.
Some Thunderbolt 3 hosts that only support DP 1.2 will be capped at a lower resolutions & refresh rates. The bit/color depth may vary in order to support higher refresh rates. The support of higher refresh rates may vary due to OS updates.

SuperDrive Compatible

Whilst most other docks on the market do not support Apple’s SuperDrive CD/DVD player, we went above and beyond to designed a driver that allows the SuperDrive to operate when connected to the TS3 Plus. It is these small details, in addition to our expertise of the macOS ecosystem, that sets CalDigit apart.

*SuperDrive support in macOS requires a one-time only driver installation. Please download driver here.
