Our NEMA 6-50 Gen 1 adapter lets you charge your Tesla Model S or Model X with Gen 1 UMC at 50 amp NEMA 6-50 outlets, commonly used for welders (not to be confused with the standard 120V NEMA 5-15 outlets which look similar but are much smaller in size).
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.
