10. When using as a DAC with computer, does Q1MKII discharge?

A: When using as a DAC for computer, Q1MKII would not discharge and use the power supply from USB port. Meanwhile the computer will charge the Q1MKII. So the red and blue light would light up together which looks like purple. Red light would go off once it's fully charged.

Note: when connected with computer, the charging time will depend on the current output. It's recommended to use >1A charger if you want to charge the Q1MKII.
