Description of Power

This Type-C docking has 2 external power sources (Type-C and DC port). If the docking
is connected to host PC, without being connected to any external power adapter, the
five USB ports (4 USB-A port and 1 USB-C port) will not work. However, the rest of the
ports will get power from host PC and will work normally. To ensure the proper
functioning of USB ports, please connect it to at least one external power adapter.

Only one power port is connected

About DC Port

Power Adapter with below specifications is suggested to be connected:
5V (15W or above)
20V (75W or above)

 When a 5V (15W or above) power adapter is connected to DC port, it only supplies

power to the docking. In this case, the host PC will not get any external power.

3

 When a 20V (75W or above) power adapter is connected to DC port, It supplies

power to charge the host PC first (max 60W, 5V/2A, 9V/3A, 15V/3A, 20V/3A),
the rest of the power (max 15W) will be supplied to the docking.

About Type-C Charging port

 It supports max 100W (20V/5A) PD Charging. When PD power Adapter is

connected, 15W of the total power will be reserved first to guarantee the
functioning of this product, the rest of the power will be used to charge the
host PC (the power that the host PC can get depends on the result of PD
protocol negotiation).

e.g.: If this product is connected to 2015 Macbook model, and then connected to a
100W Power Adapter to Type-C female. Of the 100w, 15w is reserved for functioning
of the docking, 85W is available for Macbook. However, after PD protocol negotiation,
the host PC needs 30W, then 30W will be used to charge for the Macbook.

Two power ports are connected

1) When DC port is connected (with 75W or above Power Adapter) prior to
Type-C port, the docking and host PC are powered from DC port with Type-C
port which like an alternative power source.

2) When DC port is connected (with 15W Power Adapter) prior to Type-C port,
the power source will be switched on from DC port to Type-C port.

3) When Type-C port is connected (with PD power Adapter) prior to DC port, the
docking and host PC are powered from Type-C port, with DC port as an
alternative power source.

4) If the two power sources are connected first and then the docking is connected
to the host PC

① If DC port is connected with 75W or above power adapter, the docking and

the host PC will be powered from DC port, with Type-C port as an
alternative power source.

② If DC port is connected with 15W Power Adapter, the docking and the host

PC will be powered from Type-C port, with DC port as alternated power
source.

③ If the active power source (power source that is supplying power) is

unplugged, the alternative power port will be switched on automatically to
be the active power source. In this case, the connected devices will get
disconnected for a few seconds and then reconnect automatically. However,
unplugging the alternative power source has no effect on the connected
devices.

Note:

Though a 75W or above power adapter is suggested to be connected to the DC port
of this product, our standard optional power adapter is 72W (20V/3.6A). The reasons
for choosing a 72W power adapter are listed below:

1) The price of a 75W power adapter is as twice as that of a 72W power adapter

2) The optional 72W power adapter is testified to be able to guarantee normal

functioning of this product when it is full loaded

1. Mini DisplayPort and HDMI can work simultaneously; Mini DisplayPort and VGA can

work simultaneously, but HDMI and VGA cannot work at the same time.

2. When connecting Mini DisplayPort and HDMI on Mac OS, the computer can read only

one EDID (Extended Display Interface Data). It is recommended using two monitors
which have the same highest resolution. If the resolutions are different for these two
monitors, please adjust manually. On Windows OS the computer can read two
different EDID´s at the same time.

3. When connecting Mini DisplayPort and VGA on Mac OS, the computer can read only

one EDID. Please connect the Mini DisplayPort port before the VGA port; otherwise
there might be no sound from the device. Please adjust the resolution for both
monitors manually. This issue will not happen on Windows OS.

4. While using Mac OS on the Dual Monitor Mode, the computer can read only one EDID.

If you are using two monitors which do not using the same resolution, there won´t be
an image. Please properly reset the resolution and adjust it manually.
