Yes, I know. Why with NEMA 14-50 Outlet. Well: The 'Wall Connector' was FREE with EVSE Rebates. Update: Received rebates check within 3 weeks ;-) Cost Efficiency. Special rates on EV charging by the utility provider. Convenience. Extra charging unit. Mobile Connector can stay in the Frunk. Safety. The equipment detects any potential faults and prevents damage to the 'actual' charger - in the car. It is easy to hook/unhook the Wall Connector when we move to our new house. By the way, I am not too fascinated by improved charging speed. I drive more than 100 miles daily, and the Mobile Connector with NEMA 14-50 is sufficient for my need at the moment. I do not charge daily either. Skip a day. Followed the manual, and the installation was straightforward. Hopefully, this video would be helpful. Thank you.
