Only one USB-C port on this tablet. With this adapter I can turn it into an Android computer and media center. I output to a 4k monitor and watch video over HDMI (the real reason I bought it). The Samsung tablet screen won't turn off, so charging was important. I used the USB-C port for charging (but I'm sure USB-3 ports work just as well). I used Bluetooth headphones for audio, but my old computer speakers work just as well through the headphone jack. Also doubles as a USB hub for my computer when needed. Very satisfied and would buy again.
