The details for setting the output voltage of MP3450

You can optimize the use of MP3450 with your laptop or portable DVD player by setting the voltage on

MP3450 less than the required voltage shown on the power adapter of laptops to avoid charging internal

battery. It can extend the working time of your laptop. Therefore, it is recommended that you set the MP3450

output voltage to 14V first, and then test to see if it powers your laptops. If not, increase MP3450 output

voltage to 16V, and retest it. Repeat this process until you reach the MP3450 voltage that will only offer the

power to your laptops but not charge internal battery. .

NOTE: If your portable device displays a low voltage/low capacity or double-beep warning while MP3450 is

connected, Please adjust the voltage setting to a higher level.

Please refer to the table when you set the voltage.
