Can you keep the 12V outlets on when the car is off?

    Looking for feedback on the dometic cf-025dc. Are people happy with it? Does it fit well in the MX?

    I have the euro CDF-25 version, works great for me in my S (with retrofitted 12V outlet) and in previous cars.

    Coolfreeze CF-35...love it. It fits in the rear, driver side corner, with the floor board at it's lowest level. Right next to the 12v outlet in the trunk.

    I'm curious, how loud are the Dometic coolers? When they're running, can you hear the compressor?

    Mine is very quiet, even when it was behind the driver's seat in the old car, I never heard it.

    Where is the relay box in the X? I pulled some of the carpet in the passenger foot well, but couldn't find it.

    Thanks for your report. It provides some clarity in this rather confusing thread. :)

    My 12v outlets stopped working yesterday. Have an appointment with the SC next Saturday. Kind of disappointing as I was shooting a video for with the tesla tire repair kit...

    Update on the Dometic cooler I purchased (described upthread).

    I've had it operating in my X for our cross country trip. Works flawlessly. Keeps items really cool/cold as selected by operator. At night when stopped at a hotel we would bring it inside and plug into into 120V outlet.

    Little to no noise.

    Hello,

    Which female receptacles should be connected? I googled about the relay and should they be 30 (12v Hot) and 87 (12v Out)?

    my 12v outlets stay on...

    i have an inverter plugged in so that i can charge my phone faster, and if i leave my phone plugged in when i go inside a friends house, i come back out to a fully charged phone or at least a phone with a much higher state of charge...

    Why don't you just use an appropriate cigarette adapter to charge your phone?

    I'd like to use a fridge and some astronomical devices when the car is off. Unfortunately both of my 12V outlet provide no continuous power and some tricks(current of OBD is small, find no relay to short) are not working for me. However, I find a way best suited to me.

    There is a main positive input line on top of the acceleration pedal fuse box, and the fastening bolt just has enough extra length allowing me to insert a spade lug and a M6 nut. Also, I use a mini fuse holder for the positive and use 14AWG silicone wire. The negative is from nearby bolt that fix a plastic to aluminium post.

    I run the cloth-tape-wrapped wires alongside the center storage and through a hole under the bar into the under side of the center console, and install a heavy duty 12V socket onto another pre-drilled hole.

    I've tested with an 180 watts portable electronic load that it will run 13.2A continuously without any difficulty.

    One disadvantage for this approach is that the opening is upward prone to dropping metal objects and short the circuit. I must be careful to place the build-in cover when not in use. I originally planned to install the socket alongside the existing 12V outlet but find out it take too much to remove stuffs that I'm not comfort with.

    Great idea and informative. I for see a weekend project in my future. Only thing different I'll do is disconnect the existing 12v wires on the two cigarette sockets and wire them in parallel to this 12v source.

    Add to the above post.
    I've also tested the original 12V which drop more for less current, 12.5V @10A.

    This probably because the wire is longer/thinner or there is additional socket and relay.

    By the way, the fuse for this Tesla 12V in the center console is 20A and it is F203 in the fuse box.

    I am pretty sure the rear and front 12v turns off a few minutes after you leave the vehicle. The rear doesn't seem to stay on full time
