    God, you newbies, you have absolutely no idea how it works, do ya?


    The startup and shutdown timers are the most important thing, and hardest to do, for in car use.

    A few years ago, getting a DC-DC ATX psu with Startup and shutdown controllers was almost impossible.

    You could get a DC-DC one after a while, but we still waited on the one with shutdown controller.



    And when it did you were looking in excess of $250 when a simple ATX PSU could be picked up for $30.


    Now you can pick up DC-DC supplies with Start/Shut that are more powerful and better quality for $90


    It is because of the early innovators and adopters that prices have come down and quality has gone up.

    The same will happen with this product.


    Now quit ya b'tching.

    Enforcer, have you ever actually done microchip programming?

    The startup / shutdown has got to be the simplest part.

    Seconded. Writing a power controller for something like this with a $4 micro is a matter of a couple hours (at the most) of work. That includes testing and debugging.

    Thats it exactly for me, I don't know how to make them so I have to wait for someone else.
    I don't want to hack something together and hope it works, and to be completely honest I don't have the time.

    So yes its $85 and yes you could probably make your own cheaper.

    But for the layman, who doesn't have the time, knowledge or patience to make their own its well worth it, for a cleanly finished, simple to use device that can be hidden away behind a glove box.

    I paid a fortune to have this sent to the UK, and it hasn't even performed properly. I have no problems running my GPS and touchscreen off of it, but it doesn't seem to be able to power my WD USB powered hard drive properly.

    harddrives are never meant to be powered by usb. That's why some require 2 ports (1 for power 1 for power and data). And There are laptop drives that take more than 1A @5v so sometimes it just wont work well no matter what.

    Also USB is only allowed 100mA per port on startup and then more up to 500mA each if needed. Harddrives actually require the most on spinup. So it was never meant for a HD to be powered off of USB. Some will work, some wont.
