Indicators
There are two LED indicators located on the back side of the camera. The red one lights up when the battery is charging, the blue one is permanently on when the camera is powered up. Another LED is on the top, it starts blinking after switching on the WiFi connection.
Connectors
All connectors are located on the left side. Of these, there are microUSB and microHDMI sockets and a microSD card slot.
Power
Removable battery compartment is located on the bottom of the case. Its door is not very easy to open, but it seats safely when closed. Battery dimensions are 33 x 30 x 11 mm, the weight is 17 g. Battery is compatible with the most common “SJ” form-factor. The battery capacity is marked as '900mAh', this will be checked below in the Teardown section of this review. Another thing to mention here is that Excelvan Q8 keeps its full functionality being connected to external power source. You can record videos and shoot stills with this cam while charging. The Q8 has a dashcam mode, which powers up and starts recording when a power source is connected and stops recording and shuts the camera down when it’s off.
Fully charged battery lets 60 minutes of continious shooting (4K30 mode, LCD on).

Almost all menu items available are pretty obvious to use from their names and options, so I put some ♦ notes only for a few of them.

After connecting the cam to a PC with a microUSB cable a mode selection prompt appears. Where you can choose between USB Mode, PC Camera and Charging Mode. The first mode is used for file transfer. The camera in this mode is recognized by PC as a standard USB storage device.
