I purchased the NEMA 14-50 plug adapter online, received it within 2 weeks. Sometimes the Tesla power plug adapters, Wall Connector and Wired Mobile Connector are out of stock. In that case you can enter your email and the Tesla Store will send you an email when the item is in stock. Best bet; figure out what your needs are and order at least a month in advance of when you expect to receive your Tesla vehicle. This is good advice for ordering any Tesla or 3rd part accessories.
