    • Pry space between ground contact and plastic casing, using a large flat blade screwdriver. Alternate prying on both ground contacts on either side of the case. The case should begin separating at the USB side of the adapter.

    • Use a smaller flat blade screwdriver to pry on the gap created between the side and the USB "front" of the adapter. Eventually you can use your hands to pull the two casing halves apart.

    • Identify where the four pins of the USB socket connect to the circuit board. They are the largest connections on the board, are all aligned in a row, and are located on the other side of the board from the back of the USB socket.

    • Prepare a 200 ohm 1/4 watt resistor that will connect between the two center pins of the 4 pin USB connector. Make a loop of one lead of the resistor, as shown in the photo. Use heat shrink or other insulated tubing to keep the longer, looped side of the resistor from shorting to the board. In the photo this is the black shape to the right of the resistor.

    • Solder the resistor to the two center pins of the four USB pins. Use a small soldering iron and a modest amount of solder. Be careful not to bridge to the outer USB pins, or the nearby, large solder point that attached the ground contact.

    • Reassemble the components into the case. Make sure the 12V pin and the ground contacts are all pushed in enough as you close the case, or the case will not close.

    • Apply a small dab of epoxy or cyanoacrylate glue to four spots where the two halves come together, and hold or clamp until dry. You could also just use a rubber band near the USB side of the case. I would not use electrical tape to hold the halves together, as it eventually would leak adhesive and make a sticky mess of things.

    • Before using with a device, test the unit in a cigarette lighter, and make sure its green LED is still lighting correctly. You can also measure between the two outer USB pins with a voltmeter, and make sure there is from 4.75 to 5.25 volts there.
