The WenStorm Tesla\/NACS Extension Cord does exactly that: 21 to 50 feet of vehicle-side reach, 50A across all lengths, 8 AWG pure copper conductors — without extending the wall-outlet side of the charger.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNot a wall-outlet extension.\u003c\/strong\u003e This is a vehicle-side cable — it goes between the EV charger's built-in NACS connector and the car's charging inlet, never between the wall outlet and the charger. If your problem is the wall outlet being too far from the parking spot, install a properly rated dedicated circuit closer to the vehicle instead; household and NEMA extension cords are generally not appropriate for continuous EV charging.
