    i use HPWC to charge my X and model3. Noticing hey connector getting quite hot when charging the X (used to be just warm). The model 3 (charges at lower amp) now gets warm. The connector appears clean. Anybody with similar experience?

    Without specific numbers, impossible to tell. But at 72 amps, the wand does get quite warm. At home I charge at 50 amps. My car has been charging for 30 minutes or so, and the wand temp is 102º F Ambient temperature in my garage today is approx 93º F, so roughly a 10º change from ambient. If I was charging at 72 amps, it would probably be around 140 (that's a guess). I don't have a model 3 (yet) but at 32 amps, I would expect something below 102º

    If the wand ever overheats, the car will complain and reduce the rate.

    Even though they look clean, just in case you may want to use a Q-tip and gentle cleaner on both the connector's contacts and your charge ports. Be sure to also dry the connections with a new Q-tip.

    It may be good to reduce the charge amperage from the screen by several amps since this should also extend the life of your Wall Connector (generating less heat both in the wall unit and connector). If you still have trouble, consider contacting [email protected].

    I have one of the original wall chargers from my Model S and I charged at 80amp. I use it now on our Model X 72amp. That handle does get hot... like almost to burning hot. This is normal as far as I know.

    Yeah, as Electric700 says, try lowering the amperage to on the X to 32 (to match the 3) and see how the handle feels (carefully).

    I had the same issue. It wasn't the cable getting hot. It was the HPWC itself. Charging was also tripping the breaker occasionally. It ended up being one of the connections at the breaker was loose.
