    Sure, if you want to blow it.

    P.S. It can be done, but it will require additional components, and aint really worth it when you can power the laptop from the cars 12 volt power source, the battery.

    My original thought was "Not for very long..."
    Have you looked in the FAQ yet?
    How about the Wiki?

    The other thing I thought of though, is that it is possible that your laptop actually needs 19 volts (I know the 2 I have do), and therefore you can power the laptop directly from the p1900, assuming that the p1900 can output enough AMPs for the laptop.

    one of my problems, i think, is that i'm using a dell latitude d600. i've read that dell builds their power structure a little different, ie, i cannot simply cut some wires and go from the p1900 to the back of the notebook.

    damnit. this was the only reason i purchased the p1900. how on earth do i get power to this thing? i've got a dell branded auto/air adapter but it looks like it needs more amps than i can give from the p1900 secondary output. here's the lable from the adapter:

    dc power adapter
    input: 11-16vdc, 8a max
    output: 19.5v - 3.34a
    max output power: 65w

    if i go back to my original plan of using the auto adapter directly to the battery, i'm back to the original problem of power drain in standby. any thoughts?
    (sorry bout the double post)

    isn't the power connector to the dell just a barrell connector on this laptop? If so, you should probably be able to connect the p1900 to the laptop with a matching barrell connector from RS. Check it & check polarity.

    If you're not comfortable doing this you can sell the p1900 and get a 12 notebook power supply like this.

    There is a very simply solution to this problem. All you will need is the Dell in-car power brick and a relay of reasonable size. Just wire the coil of the relay to your ignition-switched power source (tapping into the cigarette lighter plug typically works just fine) and wire the output switch of the relay in-line with the fat cable that goes to your battery. Save the P1900 to power any external devices like disks and USB hubs.

    Doesn't dell power brick come with the cig adapter? And in most car, cig lighter socket is OFF when the key is out.
