Our new NEMA 10-50 Gen 1 adapter lets you charge your Tesla™ Model S™ or Model X™ with Gen 1 UMC at 50 amp 3-wire outlets, commonly used for electric cooking ranges in homes built prior to 1996. This adapter is also fully compatible with the JESLA™ charger for use with other EVs.
Just like Tesla™'s OEM adapters, our adapter has an internal circuit that communicates with the car to automatically set the appropriate 40 amp charging current. No need to manually set the current - simply plug it in! Cable length is 18 inches.
