Can you leave the Khadas Tone Board constantly plugged into power?

I just got the Tone board and use the coax as the input instead of the USB C. I have the USB C plugged in with the iPhone power block and was wondering if I ever have to unplug it. If I do have to unplug it, would it be fine if I just unplug it at night and have it plugged in all day? Thanks in advance

My Khadas board is also hooked up to my PC and has been “on” 24/7 for nearly eight (8) months now and it runs “COOL”. I have detected virtually no heat build up at all from this DAC unit at max digital volume. The hottest it ever gets is maybe 60-62 C.
