Is there a maximum length extension cable for use with the Tesla granny charger? I’m taking a trip to France later this year and one charging option at my destination is to run a cable from the apartment to the car and use Tesla’s granny charger to top up the battery overnight. I’m not quite sure how long an extension cable I’d need, so wondering if there is a recommended maximum length I need to consider. If I go for this option I’d get the cable from a retailer who offers good quality EV cables.
