Our NEMA 14-50 Gen 1 adapter lets you charge your Tesla Model S or Model X with Gen 1 UMC at NEMA 14-50, 50 amp 4-wire outlets. These outlets are commonly found at RV parks/campgrounds, and are often used for electric ovens in homes. The plug has a convenient handle making it easy to unplug, and safer by keeping your fingers away from the outlet.
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.
