One adjustable voltage output power jack, can choose output voltage from 9V、12V、15V、18V. The output current is 200mA. Three independent output power jacks, each line’s output voltage is 9V, and the output current is 200mA. Four parallel output power jacks, each line’s output voltage is 9V. And support the whole 400mA power needs that the four lines parallel into an independent output power jack
