    12V USB Hub, Help!

    I've been looking, but I'm having a hell of a time finding a USB hub that accepts 12V DC input.

    I'm more than willing to chop off the end of an AC adapter, but so far all that i'm seeing are hubs with an AC adapter that changes the current to 5V DC.

    Much love to anybody who can find me a USB Hub that takes 12V DC input, regardless of whether or not I have to modify an AC adapter.

    I have everything finally done I just need more USB ports but I don't want to run a 5V line from the PSU all the way to the front of the car when I have an easily accessible 12v source already available.

    Or...

    Is there some kind of really easy way to step down 12v to 5v?

    I already know there are many options for powering a hub, however the only available option I have is a 12V line, hence why I am simply looking for a hub that accepts 12V input.

    It is NOT your only option, it is just the option you prefer.

    Now, there probably are not any 12v hubs, since USB standard dictates 5 volts. No point in converting 110 to 12 and then doing it again inside the hub. Manufacturers use the cheapest method, and since they need to include a wall wart to power the hub, they include a 5 volt wall wart, to avoid needing additional regulation inside the hub.

    Your second question was how to convert 12 volts to 5 volts. THAT HAS BEEN COVERED, search for the answer. THERE ARE SEVERAL PRODUCTS THAT CAN DO THIS.

    Agreed. You are very unlikely to find a 12v USB hub. As said there are other alternative methods.

    Not really. Most logic circuits in computers run at 5v. Everything USB is 5v. Just because a car runs on 12v doesn't mean there'd be something readily available as far as USB hubs go, for cars.

    12v hubs are available, but they are not cheap.

    I have a 12v 4 port hub and they are excellent (different manufacturer though).

    Here is an example

    Hope it helps,

    Wow for 120 euro for a 12VDC 4 ports hub?
    I would buy a 5VDC hub for about 10-15 bucks and go t wally world and get an auto adapter that can do 1-2 AMP for another 25 bucks or one of the 5V POL in the store.

    Or a 5 volt 2 amp voltage regulator (7805) for one dollar My external USB DVD drive needs 7.5 volts and I use a simple $1 regulator (7808) on a small heatsink to produce 8V (close enough). Worked great for 2 years now.
