    I'm wondering what the likelihood is that I'll need an extension cord when I have my Tesla? These cords are at a one year low on Amazon and I was wondering if I should pull the trigger....

    50-foot extension - $150
    25-foot extension - $75

    Any thoughts from people who own a Tesla?

    Ordinarily, I would say no. You're going to charge at home every night. You're going to use superchargers on long trips.

    But I can imagine some scenarios where you'll actually want to plug into a NEMA 14-50 outlet.
    • You want to spend a week at a campsite, and will be using shore power to charge your car.
    • You're spending a week visiting a friend/relative. They're willing to let you plug in your car at their house. The dryer outlet location requires the use of an extension cord.
    The Tesla Mobile Connector comes with a 20 foot cord. For the first case, I would think you could park close enough to not need an extension cord. For the second case, whether you need a cord, and how long it should be will really depend on your friend's house.

    Same price at Home Depot:

    Amazon often tracks the major retailers and will lower their prices to match quite quickly.

    Matt,
    If you plan to take it on road trips I would strongly suggest a 25' cord such as the one you linked to from Amazon (that is the same one I bought about 2 years ago). I would also suggest investing in a CHAdeMO adapter, as I suspect that there will be times and places where a supercharger isn't available, but a level 3 from Chargepoint, eVgo, or Blink is on the route you want to take. I have used both items on road trips and am glad I had them along, as I either would have stayed overnight somewhere or taken a totally different route than the one I wanted to because those were the only options left.

    Seems like a really good idea actually.. got thinking that I could steal the dryer outlet at some friends' houses if the cord was long enough.

    So I traveled to pretty remote Lake Cumberland destination with an outdoor 110v plug about 21 feet from the driveway. I ended making it work by driving slightly into the flower beds. But in the future, I was hoping this would be a usable solution.

    Any thoughts whether this should work? It seems rated high enough.

    @slasher016 that looks perfect for a 25ft cord.

    I bought a 10 gauge 75ft cord which I will keep in the car when traveling. The extra gauge is with the overkill for the long length considering the constant power draw (and I may push 16A through it). Very nice quality cord and reasonable price. This is the one I bought:

    I know there are a lot of 120V 15 amp outlets with really crappy installs. At a minimum, I would babysit it for an hour or more and check for heat/smells. This is good advice even when charging at 12 amps on an unknown outlet.

    I should clarify I would only do 16A on a 5-20 outlet, but those are very common now.
