I'm currently leasing a Volt that will expire at the end of the year, and have a Tesla 3 coming within a few months. The charger I installed for the Volt connects to a 14-50 circuit and is capable of outputting 40 amps using the standard J1772 port (It's a Juicebox). At first, I thought about replacing this with either the mobile charging cable directly connected to the 14-50 circuit, or purchasing Tesla's wall charger. However, I later learned that a Tesla manufactured J1772 port adapter exist for Tesla's vehicles and that it isn't restricted to 32 amps like the v2 mobile charging cable is. The adapter is also $95 vs the $500 Tesla wall charger and still leaves the option to quickly charge non-tesla vehicles. With an ever-growing number of friends and family purchasing electronically chargeable vehicles, some of which aren't made by Tesla, I'm curious what other people are doing to prepare their homes for a future where we could be "gas stations" for our friends and family when they visit, or for when is it common to own more than one electronically charged vehicle. I know that in the past, there have been long lines for public charging stations at times such as the holidays where a large number of people travel at the same time and it would be nice to have a backup power supply available to them if they want to visit. With the recent influx of Model 3s hitting the roads, I'm going to assume this Christmas is going to be especially awful this year.
