External USB Drive Power Tags: Peripherals USB Power External USB Last response: August 2, 2013 10:07 AM in Computer Peripherals Share audioee August 2, 2013 10:01:02 AM For external drives that need 2 USB ports to run, can I plug one port into the computer for the data connection and one into one of the AC to USB wall warts for additional power? More about : external usb drive power photonboy August 2, 2013 10:07:25 AM I believe so. I see no danger in testing this. I'm not certain how it is configured though. One of the USB connections may be for DATA + POWER whereas the 2nd one may be POWER ONLY. If it doesn't work, try switching them. Can't find your answer ? Ask !
