    I'm going to pull out the 323 center console I installed in the wagon and am going to install the stock armrest and center console back into the wagon.

    I want to install new ports but instead of using the unreliable dash mount units I'm thinking of using a central power supply and running dumb ports which would make it easier to install them as there isn't much room on the stock console for USB ports. This is the power supply I'm thinking of using:

    These are the parameters of the unit:

    1>.Module Name:6-USB 5V/8A Step Down module;

    2>.Input Voltage DC 8V-40V;

    3>.Output Power: 5V/8A(8A is total output current);

    4>.Efficiency: 95% (MAX);

    5>.Module size: 68mm*62mm*34mm;

    6>.Working temperature: -40°C-+85°C;

    7>.Reverse connection protection:Yes;

    8>.Over current protection:Yes;

    9>.Over temperature protection:Yes;

    10>.Load capacity: 8A(Max);

    11>.Input interfaceDC5.5*2.1cm Socket or Terminal;

    I want the capability of being able to charge QC3.0 phones and tablets quickly at the same time. The unit maxes at 8a which would mean if each port were utilized it would charge at 1.25A(8a÷6 inputs = 1.25A). If so this won't be enough amperage to actually quick charge all the units at the same time in fast charge mode. Is my math correct?

    Or would I need to go with a higher voltage step down transformer like this:

    Your math is correct at 1.25A but it's not likely that you'll get more than that from any port at any given time unless the circuit specifies it. There are units specifically designed for vehicles, looks this one: https://www.google.com/search?q=12v...T0Aw&start=20&sa=N#mhpiv=15&spf=1534568645096

    I bought 4 of those for the wagon. I already had to replace two of them. My guess is I burned them out because I have them wired as constant on.

    I think a central power supply that regulates the power will lengthen the life of the ports but maybe I'm wrong.

    that may be this issue. all the ones i installed were on a properly wired stand alone fuse panel from the factory systems, integrated relay, and wired to an accessory source.

    So in my case where I want them constantly on would a module like the one I posted have any effect on the longevity and reliability of the ports?
