I installed a 14-50R, 50 amp 240 receptacle in the shed at our vacation cabin and permanently leave the Nissan EVSE plugged in there. I’ve used it to charge my friends Tesla Y a few times with his adaptor. At home I have a Eaton hard wired EVSE that I installed in 2015 that is used as the primary charger source.
I bought a second Nissan EVSE 120/240v on eBay for only $225 and keep it in the truck in the bag. In 5+ years of leaf ownership I’ve never used the one in the trunk but I keep it there in case. The ability to plug it into either 120 or 240 is an advantage.
