ThunderSync16 is a high speed data transfer and charging product designed to allow 16 USB2.0 devices to connect to a Thunderbolt host computer without the bottleneck experienced when using traditional USB hubs.

  • Transfer data to multiple USB devices much quicker than using a standard USB hub. ThunderSync uses a 20Gbps Thunderbolt 2 host interface vs 480Mbps for USB2.0
  • Provides more USB Endpoints vs a standard USB hub meaning that USB endpoint limitations can be avoided in most applications
  • Application Programming Interface and 12 Watt per-port intelligent, universal charging as standard. 200 Watts total power across all ports



  • Mobile software QA automation systems.
  • Super high-speed iOS and Android device restore and imaging.
  • High-speed mobile device content transfer.
  • Mobile device programming and test.
  • Reverse-logistics charge/erase/restore stations.
  • VR Video capture.
  • Mobile device staging / provisioning.
  • Applications where data transfer speed to multiple USB devices is important.
  • Applications where standard data transfer methods are too slow.


  • Full 480Mbps bandwidth to each USB2.0 device simultaneously.
  • 20Gbps Thunderbolt 2 host interface.
  • High-current (2.4Amp / 12W) charging for mobile devices.
  • Supports SDP, CDP, DCP, BC1.x, SE1, Apple, Samsung, ACA-x, YD/T-1591, RIM etc.
  • Application Programming Interface (API) for control and monitoring of ports. Available for Mac / Windows / Linux (x86/Arm).
  • Dual Thunderbolt 2 ports for chaining multiple ThunderSync’s or Thunderbolt peripherals.
  • Compatible with Apple Configurator, iTunes and most MDM software packages as well as Mobile Heartbeat.
  • Live Viewer App.
  • The internal architecture of ThunderSync is such that it has 4 times more USB endpoints than a typical host computer. This is a clear benefit for applications which suffer from endpoint limitations when using standard USB hub architectures.
  • 2 Year RTB warranty.


ThunderSync16 is a high speed data transfer and charging product designed to allow 16 USB2.0 devices to connect to a Thunderbolt host computer without the bottleneck experienced when using traditional USB hubs.
To allow the 16 USB2.0 devices to connect to the host without any bottleneck, ThunderSync offers a 480Mbps data rate to each of the 16 USB2.0 devices and transfers this data (480Mbps x 16 = 7.68Gbps), over Thunderbolt (20Gbps) to the host computer. This means that you can transfer data to 16 USB devices in the same speed as transferring to a single USB device.
With an internal 320W power supply, and each port offering 2.4A, you have the power to charge your USB devices too. ThunderSync offers universal charging and its device charging profiles can be updated should new charging profiles appear on the market or if we add new features. Updating the firmware is quick (and free of charge) and we supply our FW Updater App for this purpose.
Internally, ThunderSync contains an Intel and Apple, Thunderbolt Certified, design which provides a robust interface between large numbers of USB devices and the Thunderbolt interface. We utilise a number of programmable components and microcontrollers in order to get the very best from the various internal interfaces within ThunderSync which ensures robust, high speed data transfer for the most demanding and mission-critical applications.
ThunderSync16 supports our application programming interface (API) which allows you to automate, monitor and control each port programatically. With the API you can monitor current consumption of each individual port, total connection time, charging time, control the 32x front panel LEDs, turn power on/off to individual ports, emulate different charging profiles, read USB VID/PID and much more.
The API is available as a free download and is updated regularly and well documented.
We also supply our Live Viewer App which allows you to monitor and control ports using a graphical user interface.
The API consists of a service module or daemon that is loaded on the host computer. The service module is accessed via JSON-RPC calls over a TCP/IP socket. Cambrionix provides sample Python code complete with the necessary JSON library code to be able to make the necessary calls for controlling Cambrionix products that are connected to the host computer.
It is of course possible to access the API from any programming environment that has support for making JSON-RPC calls over a TCP/IP socket.
To use ThunderSync16, simply connect to a Thunderbolt host and connect your USB devices and they will be seen by whatever software your host is using. Or, if you are a more advanced user, download our API for full control. If you need more than 16x downstream ports, simply daisy-chain another ThunderSync16 via the built-in additional Thunderbolt port.
