  • Would a USB OBDII reader provide power to my device?

    I've embedded an Androit tablet in my dash. However, the unit has a single USB port which is used to keep the device charged. The tablet does not have Bluetooth so I'm looking at USB-based OBDII readers. My biggest concern is that I couldn't charge the unit while using the reader, unless it provided power.

    Any ideas?

    i would try to connect a y-power-usb cable(like them with ext. 2,5" hdd) between the devices. i think, it could work.

      That's a very interesting idea. I didn't even know these things existed. It would at least solve my problem of having the port inaccessible so I can update software/transfer files. I think the hard part would be finding a cable with a 90-degree head so it can fit in the enclosure.

        you don't know something about these usb cables? you need it, because one usb2.0-port don't have enough power to start the hdd.

        90 of which side?

          The 90 degree angle would be needed on the tablet's end. The tablet is sandwiched into an enclosure and unfortunately, the USB port is on the side. Here'a a photo of the enclosure.

              So I would have to go:

              USB-DC charger & ODBII reader > Y splitter > adapter to mini-A USB > mini-A USB 90 degree cable

                    I believe it is Mini-A. It's the same as most GPS devices.

                        most tablets will not charge when using an OTG cable. they expect to be providing power to the accessory, not the other way around.
