All the ports you need
Connect & Charge
In addition to all this, the TS3 Plus is the best option for both Mac and PC laptop charging. While other Thunderbolt™ 3 docks on the market can only charge one platform, CalDigit’s Thunderbolt™ 3 docks will provide up to 87W power delivery for both Mac and PC users.
Thunderbolt™ 3 Workflow Solution
With the TS3 Plus, a single Thunderbolt™ 3 port from your laptop expands to 15 ports! Power users need as many ports as they can get hold of and the TS3 Plus delivers on this promise. Whether you need multiple USB ports, dual 4K display connectivity, Digital Optical Audio out, or an SD Card Reader, the TS3 Plus packs everything into an incredibly compact unit. Don’t compromise on connectivity with the TS3 Plus!
7 USB Ports
With five USB-A 3.0 ** ports and two USB-C ports, users have a total of seven ports to connect multiple USB devices to their ultra slim laptops. Featuring both front and rear USB ports, the TS3 Plus packs a large amount of connectivity into such a compact device. The rear USB-C port features USB 3.1 Gen. 2 (10Gb/s) which allows users to connect their ultra-fast SSD drives for incredible performance.
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.
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.
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.

Yes, the Element Hub works on Thunderbolt 3 computers.
Thunderbolt 4 and Thunderbolt 3 are both 40Gb/s, and the Element Hub works great on both.
Some Windows PC manufacturers have limited the performance of their Thunderbolt 3 ports in order to restrict the number of external monitors that can be attached, and in some cases they have also removed laptop charging. Check to see if your PC supports two displays, and charging through the Thunderbolt 3 ports.
Apple M1 based computers only support one external monitor in total from their Thunderbolt/USB4 ports. Intel based Macs can support two displays through the Element Hub.
All Macs are required to update to macOS 11.0 Big Sur or above in order to be compatible with the Element Hub.
The TS3 should be used with a 40Gb/s Thunderbolt 3 cable, or a Thunderbolt 4 40Gb/s cable.
Make sure to either use the included Thunderbolt 3 cable or a certified 40Gb/s Thunderbolt 3 cable. Not all Thunderbolt 3 cables are 40Gb/s and some only offer 20Gb/s. Check your cable manufacturer’s specifications.
