  1. Extract the solar panel from the garden lights

    Take apart the garden lights to gain access to the solar panel. Extract the solar panel from the unit, and cut the wires connecting the panel to the lights. Do not cut the wires too short.

  2. Strip the wires of the solar panel, and solder a diode to the positive wire

    Strip the coating around the ends of the wires. Position the diode on the positive wire so that the stripe on the diode does not face the solar panel. Solder the diode to the wire.

  3. Remove the plug from the USB cord, and strip the wires

    Cut the USB cord near the plug. Strip the coating near the ends of the black and red wires.

  4. Solder the solar panel to the USB cooler

    Solder the positive wire on the solar panel to the red wire on the USB cooler, and do the same with the negative and black wires. Secure the solar panel to the cooler with the hot glue gun.

  5. Trace the device, and cut the lid

    Place the device atop the lid of the Styrofoam cooler so that the USB cooler is on the bottom. Trace the shape of the USB cooler on the lid, then use the knife to cut out the shape.

  6. Glue the device to the lid

    Seat the device halfway in the hole you cut out in the lid. Glue the device to the lid.
