Indicator light prompt: When charging the built-in battery, there is a power display, which is completed by 4 LED lights. When charging, the 4 lights are on in a cycle, and the 4 lights are always on after the battery is fully charged. After unplugging the adapter, the 4 lights flash at the same time and then go out. , 75% are 3 lights, when not in use, all go out.

Discharge state: When the USB Type-C1 port of the hub is connected to the adapter or the USB Type-C2 port is connected to the MACBOOK or both devices are connected at the same time, the USB 3.0 port will charge other devices; when the hub is not connected to the adapter or MACBOOK, press the hardware Switch, switch to mobile power to discharge, USB 3.0 port to charge other devices, automatically disconnect when the device is fully charged, and there is a mobile power reminder light when charging.

After adopting the above-mentioned structure, the beneficial effects of the present invention are as follows: the present invention can expand more data interfaces at first, and solve the problem that users use the single Type-C port of the computer to upload and download data; the HDMI video output interface is added, and the computer video The screen is output to other devices; the built-in large-capacity mobile power supply can charge other mobile devices; it adopts an ultra-thin appearance design and is easy to carry.
