The LMP USB-C mini Dock can be seen as the digital version of a “Swiss Army Knife” when it comes to versatility and ease of use. There are 8 ports with which you can share or transfer data, reach to the internet or a network at high speed, make use of an external monitor with up to 4K resolution or charge a smartphone or tablet while you power up the laptop at the same time. All these ports have been combined in a sleak dock made out of aluminum.
The HDMI port allows the use of an external monitor or TV with a maximum resolution of 4K @ 30 Hz. The USB 3.0 ports transfer data from and to the laptop and are ideal for attaching multiple USB devices such as an external USB HDD/SSD enclosure, a USB mouse or a USB printer. The marked USB port (1.5A/BC1.2) can charge a smartphone or tablet with up to 1.5A. Over the Gigabit Ethernet port, a speedy connection to the internet or network can be established (no driver needed). The card reader supports SD (including SDHC/XC formats) as well as microSD memory cards and transfers photos and videos quickly to the computer. The USB-C port can be used to charge the laptop through a USB-C power adapter (Power Delivery) or as a data port.
Easy to use, easy to carry, not wanting to miss it!
Note: Not compatible with Apple USB SuperDrive. May evolve heat when in use. For highest possible resolution of 4K @ 30 Hz over HDMI, attached display or TV must support the resolution and refresh rate.
Basically, you can use only iMac (27-inch, Late 2009) and iMac (27-inch, Mid 2010) with a Mini-DisplayPort connection with current Mac with Thunderbolt 3 (USB-C) ports. You need a USB-C to Mini-DisplayPort adapter (e.g. 16134/16138, LMP USB-C to Mini-DisplayPort adapter) or a USB-C dock with Mini-DisplayPort port (e.g. 18641/18645/19009, LMP USB-C Travel Dock 4K 9 Port or 17113/17278/18954, LMP USB-C Compact Dock 4K 8 Port or 17116, LMP USB-C Display Dock 4K 10 Port). Then a Mini-DisplayPort to Mini-DisplayPort cable (8305, LMP Mini-DisplayPort to Mini-DisplayPort cable) must be attached to the dock and the iMac.
With iMac (Mid 2011 to Mid 2014), it is possible to use the iMac as monitor with a Thunderbolt connection only. With newer iMac, a Target Mode with an iMac is not possible anymore.

It is normal that any USB-C hub or dock becomes hot when attached to the laptop. The aluminum housing is meant to dissipate the heat from the inside to the environment. There is a number of chipsets working on the inside which are producing heat since they are constantly in a stand-by position to react quickly should any port be used. The surface temperature is well within the allowed limits and reaches a maximum of 46° C when all ports are in full use. The heat does neither pose a danger to the laptop or any attached device, nor does it influence the USB-C hub’s/dock’s performance or even shorten the life-span.
Furthermore, the surface appears to be hotter than it actually is since it is touched with the very senstive fingertips. We suggest to remove the USB-C hub/dock when not needed in order not to emitt unnecessary heat to the environment and not to use any energy.
