Stupid question, I have an electronic device I use in my office that connects to the serial port of my desktop. The 9vDC 200ma power supply went out and I found another 9v 600ma supply in a drawer. Would the difference hurt the device or would it just allow for more current if needed? Also when I tested the voltage of the larger supply it read 12v even though the lable shows 9v. Is that normal?
