DC adapter?

What is a reliable DC power adapter for the LattePanda Alpha? I have an issue where I have a display connection that runs off USB-C power/input but there is only one USB-C port on the LP Alpha which is being used for the power. I haven't been able to find the correct kind of USB-C splitter that can send power to the LP Alpha and send power/data out to my display from the same port. So I'm looking for a good DC adapter that I can plug into the connection on the board to free up the USB-C for my power/Data out.
