I have a Tesla mobile connector and was wondering if I can use it - along with a J1772 adapter - as the fulltime option to charge my Lightning. I don't have an option to install a hard wired charger.
What others have said. The adapter will likely be the first point of failure. I charge my truck with a Tesla Wall Connector. Bought it before they released the Universal-style. For months I used a TeslaTap 80amp adapter (not the compact one) and eventually I started having issues with it.
I recently bought the A2Z adapter to replace the TeslaTap. Not only is it more compact and less expensive, but the quality also seems higher.
Lastly, if you have to charge outside like I do, buy a weather-resistant charge port cover. That way you’re less likely to have water get into the insides of the adapter. Happened to me before.
I use a 60A rated Lectron adapter to charge at 48A at home from our Tesla charger or at 40A from a Tesla Corded Mobile Connector at my shop. The Corded Mobile Connector is the same as their regular mobile connector, but hardwired with a NEMA 14-50 plug and it charges at 40A instead of the 32A of their gen-2 UMC.
