Tesla Refrigerator and Cooler Blog

If you're looking to power a fridge in the trunk (boot) of your Tesla Model 3 Highland, you'll notice there’s no built-in cigarette lighter plug or 12V outlet in the trunk area. However, there are workarounds that allow you to safely and effectively power a fridge for your road trips or everyday needs. This guide provides a step-by-step tutorial to help you achieve this.

1. Identify the Power Source in Your Model 3 Highland

Tesla Model 3 Highland offers a 12V power outlet located in the front console. This outlet can provide sufficient power for a small fridge, as most portable car fridges are designed to operate on a 12V supply. However, since the power outlet is located in the front of the car and not in the trunk, you’ll need a way to route power to the back.

2. Choose the Right Equipment

Before proceeding, you’ll need the following items:

• 12V Extension Cable: A long, heavy-duty 12V extension cable with the appropriate connectors for your fridge.
• Cable Organizer: Velcro straps or cable clips to secure the cable along the route.
• Optional Power Inverter (if needed): If your fridge requires AC power, you may need a 12V to AC power inverter.
• Optional Portable Power Station: If running a cable is inconvenient, a portable power station can provide power directly in the trunk.

3. Route the Extension Cable

To power the fridge using the 12V outlet in the front console, follow these steps:

1. Connect the Extension Cable: Plug one end of the 12V extension cable into the front console power outlet.
2. Route the Cable:
   1. Run the cable along the center console and under the seats toward the rear.
   2. Make sure the cable is tucked away neatly to avoid tangling or interfering with passengers.
   3. Use cable clips or Velcro straps to secure the cable along its path.
3. Reach the Trunk: Route the cable into the trunk area by passing it under the rear seats. You may need to fold the rear seats down temporarily to simplify the process.

4. Connect and Test the Fridge

Once the cable is in the trunk:

1. Connect the Fridge: Plug the fridge’s power cord into the extension cable.
2. Turn On the Fridge: Power on the fridge and ensure it’s operating correctly. Check for stable cooling and monitor for any issues with the power connection.

5. Portable Power Station Option (Alternative)

If you prefer not to route a cable through the car:

1. Choose a Power Station: Select a portable power station that supports 12V or AC power. Look for one with sufficient capacity to run your fridge for the desired duration.
2. Place in the Trunk: Position the power station next to the fridge in the trunk.
3. Connect the Fridge: Plug the fridge directly into the power station and operate it as needed.

6. Monitor Power Usage

Fridges can consume a significant amount of power, especially in high-temperature conditions. To avoid draining your Tesla’s battery:

• Use the fridge only when the car is in use, or monitor the power draw with a battery management app.
• Consider turning off the fridge when not needed for extended periods.

7. Safety Tips

• Avoid Overloading: Ensure the fridge and other devices do not exceed the 12V outlet’s power rating.
• Cable Management: Keep cables away from moving parts like seats or doors to prevent damage.
• Secure the Fridge: Use straps or anchors to secure the fridge in the trunk to prevent it from shifting during driving.

Conclusion

While Tesla Model 3 Highland doesn’t have a dedicated 12V outlet in the trunk, powering a fridge is entirely possible with a bit of preparation. Whether you choose to use an extension cable from the front console or opt for a portable power station, you can enjoy the convenience of chilled refreshments on the go. Follow these steps carefully to ensure safe and reliable operation of your fridge during your trips.
