    Don't use the Lilliputs power regulator (hence forth known as the egg) because they are carp.

    Use a proper regulator.

    Mmmm carp. Tasty.


    I second that though, use the output from your PSU if you can.

    As already mentioned I can't use the regulated output from my Carnetix, not enough amps.

    i havee this hub and it is excelnt.
    since i am using a power inverter to power up my lappy, powering the hub was a pieve of cake, plug and play.
    ir works perfectly with hibernation, i have not yet had a device that i had to replug or didnt work after hibernation.
    i really recomment this hub ... keep in mind it BIG !
    even by taking it apart, you cant really make it smaller to fit to tight spaces. i have a truck and still had hard time finding a room for it.

    You won't need that much unless you're actually planning on using that much, but it wouldn't hurt to buy a higher output regulator.

    All 7 hubs are needed, whether or not they'll use that much who knows.

    But the point is there's no way the P1900 will power it let alone it and my Liliput.

    I don't understand. What's so special about this USB hub?
    I picked up one of these on sale for like 8 dollars. Wired to +12 on my M2-ATX. Have 5 devices running off of it without any problems - Wifi, Bluetooth dongle, USB webcam, GPS, I-BUS adapter and occasionally a USB flash drive. Why so excited about the 29.99 price for this one?

    If it is taking in 12 volts and outputting 5 volts, it has some sort of regulator inside of it. I bet that regulator accepts a range of volts and not just exactly 12 volts. The only way to know is to test it with a multimeter though.
    I agree. There is definitely a 5V regulator that can handle at least 3500mA with some degree of input tolerance. At least +/-1V minimum, and I'd expect the wall adapter to be at least 14V no-load. There could also be some parts using the 12V but I doubt it. Someone could always post up pics of the PCB and we could figure it out.

    Starting slow

    I am a certified newb, so please excuse the simplicity of my question and interest at this point. I am still researching a path on a carpc, but I would like to get a hub installed to power phone, Zune and etc sooner vs. later. That would allow me to poke around under the hood (literally) and get a better understanding of my options for wiring and placemet. It would also potentially limit the damage I could do to my car and wallet if I find I'm solder challenged.

    Sorry for the long intro, but it seems that most discussion around USB hubs assume you have a base PC or regulated power source to plug into. Considering I do not, would you recommend a hub like this perhaps with 2 x 7812 Regulators and a capacitor balancing the input and preventing spikes to the hub? Or am I missing the mark completely?

    Thanks in advance

    FYI - My car is a 2006 BMW X3.

    I think you're missing the mark. You don't need a hub for powering/charging. The normal lighter socket USB/zune/phone/etc. charger will do the trick for less.
