There is only one USB-C cable inside the Inspiroy Giano box. You can charge/connect the tablet to your computer/laptop simply by the one cable (the USB-C port is on the top left of the Giano tablet).
After connection, the smart LCD screen will show bright immediately, then you can check the battery status on the LCD screen.
Besides, you can also check the battery status in your driver (it’s on the bottom right corner of your driver).
