Kensington USB-C Universal Dock with Power Delivery Review - SD4600P

Buy it on Amazon - http://lon.tv/kenusb (affiliate link) - The Kensington USB-C dock with power delivery appears to do what it says it can do - a single USB-C cable connection that provides power for charging (up to 60 watts) along with two video outputs, gigabit ethernet, audio, and a number of USB 3.0 connectors including one USB type C connector.

Apple Macbook (2015 version) 2. Dell XPS 15 (2016 version) 3. Lenovo Yoga 900s (2016 version) 4. A more generic Chuwi Windows tablet that charges via USB-C. On the surface, at least with the Macbook, everything appears to work as advertised. Once connected the computer starts charging, ports light up, the displays come to life, and it all seems to work once the very small ethernet driver is installed. Very cool to have a single cable driving all of it. The Mac can only support 2 displays (built in display + the external) but it can mirror the output of the HDMI to the Displayport or vice versa. So you get three displays but two are mirrored. Performance is an issue here unfortunately. Sometimes everything works great with true USB 3.0 speeds on connected devices. The ethernet transmits at 800-900 megabits per second (consistent with other ethernet adapters I've used), and the USB 3.0 ports as well as the USB-C port deliver the full performance of my portable USB 3 SSDs transferring several hundred megabytes per second. Other times (and this is more often the case than not) the dock limits performance on all ports to roughly USB 2.0 speeds. It's almost as though it's not negotiating the main USB connection properly each time I plug it in. The reason is that if there's no keyboard or other simple USB device plugged into the dock when it first powers on it will immediately redirect its cable bandwidth to the two display outputs and dramatically reduce the performance of the USB ports and ethernet connection. If that simple device is connected and power is cycled on the dock all is good again. I've found the dock can maintain full USB 3 speeds with a single 1080p display. But if two 1080p sources are running (or a 4k source) the other ports will power down to USB 2.0 performance. The reason is that there is not enough bandwidth on the cable to support the dual displays + USB 3 data performance. Kensington should be more clear with this performance issue in their marketing. There are also some power considerations to make with this. While the dock does provide ample power for ultrabook class PCs like the Macbook and other power sipping devices, larger laptops will need more juice. For example my Dell XPS 15 uses a 130W power adapter and the dock only provides 60. So while the dock can power the laptop under normal workloads, games and other strenuous activities that require more power will be problematic. The laptop will either run slower than its full potential to compensate or it will draw off the battery to get the power it needs. In the case of the Lenovo Yoga 900s, the USB-C port is not configured to power the laptop. So while it gets the USB, ethernet, and video benefits the 900s does not get the charge while connected to the dock. The Chuwi tablet didn't do anything - no charging and no USB power either. I've also found the display output to not always work on the Dell XPS 15, requiring a number of disconnects and reconnects to get working. So to sum it all up: You'll need to do the research ahead of time on your particular device to ensure the following: 1. The USB-C port is configured to provide power to the device 2. The USB-C port is not just a power port but also is able to pass data back and forth. 3. The USB-C port can run at the full USB 3.0/3.1 speeds (some laptops have them only at 2.0 speeds) 4. The USB-C port is configured to pass video through the port as well.
