We used this connector in our garage to charge our cars at 40 amps but have recently installed our new signature wall connectors so we no longer need it. This is a great option to leave plugged into your 14-50 outlet all the time and allows you to store your Mobile Connector in your car. The Corded Mobile Connector has an integrated 240 volt 50 amp rated plug for high power output. A seamless design provides a low profile connection, allowing for use with covered outdoor outlets. Includes: 1 x NEMA-14-50 corded mobile connector (with 20 ft cable) 1 x storage bag Tesla sells these for $520 but you can get this one for $410 shipped anywhere in the US. We'll also ship to Canada for an additional fee. PM if you have any questions.
