Tesla now clips you for $45 for the NEMA 14-50 plug adapter. Before that it cost $35 and before that is was included at no additional charge with the early Model 3 vehicles.An electrician will be installing a 14-50 on 5/3. Overall I just plan on using the included mobile connector and I’ll have to purchase this piece as well to plug into the mobile connector which then plugs into the receptacle. Gen 2 NEMA Adapters
The mobile connector and Gen 2 Nema adapter will be permanently plugged into the 14-50 outlet. I know that I can purchase 3rd party chargers or a Tesla wall connector(which most Tesla owners don’t buy for the pure fact of price) , but for now until I see a reason to upgrade this should work just fine unless there’s a downside to it.
Another important accessory is the Tesla Cable Organizer for $35 on the Tesla Store (This item currently shows as being out of stock.) If you enter your email you will receive notification when this item is again available (probably just a couple of weeks). You can also assemble these parts separately, fashion your own or buy a similar cable organizer on Amazon, Etc.
First, not obvious, is the Cable Organizer includes a wall mount bracket (Tesla calls this the chassis holder) for the Mobile Connector electronics unit. You want to use this or something similar to relieve the strain from the weight of the Mobile Connector chassis from the power plug and the receptacle. The power plug is not designed to continuously support the weight of the Mobile Connector chassis. Over time when left unsupported the power plug can fail.
Second the Cable Organizer provides a hook to wrap the charging cord. You may also want to buy a retainer for the charging connector so it is not subject to dirt, damage etc. There are many examples of 3-D printed charging connector retainers on Amazon, Etsy and eBay.
