    Is there a limitation on this?

    Reason I ask is that I am in a Townhouse and the distance from my nearest plug to my parking space is about 40 feet. I am hoping that I will not have to install a plug closer to the car. :confused:

    I believe the charge is built into the car, so the question is more how long can the cord be. IIRC it requires a certain guage cable, which may be pricy, but the distance should be fairly unlimited given a large enough cord.

    I saw that DaveD has a heavy gauge extension cord for his 110 MC. I don't know about 220 volt MC extension cords.

    Extension Cords for the NEMA 14-50 are readily available but are quite heavy. Just google "50 amp RV extension cord".

    Yes, all Tesla models have the charger built into the car.
    But they have special connectors so you can't just use "any old cable". You need an extension cord connected to one of their special cables.

    OK I did know that the actual charger was in the car. What I am wondering is if there is a maximum distance that you can run an extention cord to the car ? I thought I heard something like 20-25 feet for the Roadster. Also, it would have to be something that is rated for OUTDOOR use.

    A high quality 12/3 extension cord of 25' or probably even 50' would be fine. The issue will be that the MC120 plug-in head and also the charging cable connector to the car are likely not weather proof.

    For one data point... I charge the Rav4EV on the end of 70' of 10/3 regularly. The charger draws 28A (220V). Certainly there is some voltage drop over that length, and the cord does get very mildly warm - and I've never had a problem after doing it for six years.
