I just bought a USB hub that I want to put in the glovebox. It comes with an AC adapter that says its 5v. And I'm going to buy a DVD drive that I want to mount up front that apparantly operates on 5v (http://www.pcalchemy.com/product_inf...products_id/44). Whats the best way to power these devices in the car. The power wires in the car are 12-14v, do I have to run a 5v wire all the way from the computer power supply in the trunk to the front of the car???
