Installation Video

Installation Instructions

In addition to viewing the video above, please carefully read instructions before you install the Rear Seat Dual USB Port.

Overview: Rear Seat Dual USB Port has been designed for those Model S owners who want to provide USB charging access for their rear seat passengers. Rear Seat Dual USB Port is a straightforward installation and requires no drilling or special tools. Note: All Rear Seat Dual USB Port components are shown in the figure below.


Step 1.  Position the Rear Seat Dual USB Port on the underside of the curved surface at the rear of the Model S center tower. Be sure to center the Rear Seat Dual USB Port using the center vertical strut of the air conditioning vent frame (see Figure below). Once you’re satisfied with positioning, remove the adhesive backing from the Rear Seat Dual USB Port and affix the unit by pressing upward firmly.


Step 2.  Position one or more adhesive cord clips (we provide 4) to route the power cable along the underside of the curved surface of the center tower toward the passenger side. Before removing the adhesive foam backing, plan the layout of the clips. The cord should be positioned to lie flat against the underside of the curved surface. Some users opt to use black permanent magic marker to color the edge of the adhesive foam backing before they are installed.

Step 3.  Remove the adhesive foam backing for the cord clips and press them into place. IMPORTANT: Be sure that the cord clip opening faces toward the center of the tower.

Step 4.  Route the power cable around the passenger side of the center tower below seat level. Plug in the 12V connector at the front of the center tower. If you choose, you can gather excess power connector cable and use a small cable strap or “twisty” to hold it together, then push the cable down next to the seat cushion.

Where does the power come from for the Rear Seat Dual USB Port?

The Rear Seat Dual USB Port taps the 12V power supply provided in the front of the Model S center tower. The Rear Seat Dual USB Port connector cable runs from the 12V power port using a standard 12V connector around the center toward below seat level and to the back curved surface of the center tower, where the Rear Seat Dual USB Port is attached. For more on this, please view video in 'Installation' tab.

Will the Rear Seat Dual USB Port get in the way of my Model S USB ports?

No. We recommend that you route the Rear Seat Dual USB Port connector cable around the passenger side of the center tower. That way, you’ll have unfettered access to the front Model S USB ports.

Will the Rear Seat Dual USB Port charge two mobile devices at once?

The Rear Seat Dual USB Port ties into the 12V port and accommodates the charging of two USB devices at once. 

Will use of the Rear Seat Dual USB Port draw down the battery and impact range?

Any battery drain will be trivially small; there should not be any noticeable impact on range. 

How do I attach the Rear Seat Dual USB Port so that it's not obvious to the rear seat passengers?

We provide a set of cord clips that are attached via peel-off adhesive to the curved underside of the center tower. Using these cord clips, the power connector cable rests against the curved underside so that the connector cable cord is placed in a more hidden position from rear seat passenger view. For more on this, please view video in 'Installation' tab.

I do not want the connector cord to be visible at all. Is this possible?

It is, although we don’t necessarily endorse it. If you are a more sophisticated DIYer (or you work with a professional installer), you can route the Rear Seat Dual USB Port connector cable under the rear panels of the center tower. This can be accomplished by removing those panels from the center tower. You will also need to disassemble the 12V power connector to free up the power cord for routing and then drill a hole in the curved panel to enable pass through of the power cord. We do NOT provide instructions for this approach because we believe that a simpler exterior approach is much easier, less error prone, and results in a compatible end result. In addition, we will not take any responsibility for any damage or malfunction caused by this (more advanced) approach. If you prefer this advanced approach, we advise you consult/hire a professional installer.

What if I need the Model S 12V port for some other purpose?

The Model S provides only one 12V port, so you’ll have two options: (1) acquire a dual outlet 12V adapter (available from many online resources); or (2) prioritize/alternate use of Rear Seat Dual USB Port and other accessories as demand for the 12V port warrants.

Will it be hard to find the Rear Seat Dual USB Port at night?

We've designed the Rear Seat Dual USB Port with a blue LED that illuminates with a gentle blue light when the connector is plugged into the 12V power source. The blue light makes the locating the Rear Seat Dual USB Port easier at night.

We are planning to spend our summer vacation in the Netherlands which includes a more than 10 hour drive. My kids will use their iPads to watch movies and I needed to find a way to provide continuous power to them during the long drive. I found a great dual USB port on

It comes with a cigarette lighter plug, a thin black cable and the actual USB hub. Installation was very easy. You can either use adhesive tape or crew the unit onto the underside of the center console. This is how it looks after installation [see images below]... -
