Note: at home, I plug my Tesla mobile connector into a dedicated 240V NEMA 14-50 outlet. If you could have a NEMA 14-50 outlet (or Tesla wall connector) installed within 25' of your car outside, that would be ideal. I will add that an extension cord is not a permanent solution. Tip: if you know how many watts an electronic uses, just divide by 120 to find amps.įinally, treat your cords carefully and always inspect for exposed wire or damage to the cable and you should be fine. I recommend getting a Kill-a-Watt for this purpose to check how much power your other electronics are using. If other electronics are plugged into that circuit and you have no other options, estimate how many amps those electronics are using and then manually dial down the amperage on the screen of the car to stay under a total (car + other electronics) of 12 amps. Familiarize yourself with the the breaker box where you are charging so that you can be sure nothing else is pkugged in on that circuit. If you have anything else on that circuit, you are likely to trip the breaker, and you never want to rely on breakers if you don't have to. Therefore, on a standard 15 amp household outlet, it will pull a max of 12 amps. A Tesla will pull a max of 80% of the amperage allowed by the type of outlet. Make sure nothing else is plugged into the circuit that you are using. In rare cases, I combine the plugs to give me 75' of extension. If I am away from home at a friend or family memer's house, the 25' or 50' cord gets the job done 90% of the time. Personally, I leave a 25' and 50' 10 gauge extension cord in my car. Use a thick gauge cord: ideally 10 gauge, and nothing thinner than a 12 gauge (smaller number is thicker). Every manual for electronics, including Tesla's, will tell you not to use an extension cord, but if you utilize safe practices, you can minimize your risk of issues: However, if you are plugging in outside, chances are, you will need to use an extension cord to reach an outlet. I'm not saying they never die, but if it was me I would like to know if it was the Wall Connector or the wiring that died.The universal mobile connector that comes with all Teslas is rated to be used outdoors. I have three Gen2 HPWC's, all running 80A (had 80A charger in one of my Teslas, also 80A charger in Taycan and eTron at home today) and they've been working fine for years. That said, I'd be curious why it stopped working. If it's a Gen1 or Gen2, there is a bit more work to replace it with the Universal Wall Connector (or any other third party EVSE), but any electrician should be able to do it. If you have a Gen3 Tesla Wall Connector, your quickest, cheapest, easiest option is to pick up the Tesla Universal Wall Connector and swap it into the same base (shut off the breaker, undo two screws IIRC, unplug the old one, plug in the new one, screw on new screws to secure it, power up the breaker, connect via WiFi to set your breaker size - 10 to maybe 20 minute job). There are a number of 3rd party options available out there, honestly, every one of them is better than Porsche (or Audi, same mobile EVSE, just different branding). Not even if it was the cheapest option (which it is not, it's the most expensive one).
