Our new NEMA L21-30 Gen 2 adapter lets you charge your Tesla Model 3, Model S, Model Y or Model X (with Gen 2 UMC) at NEMA L21-30 twist-locking outlets.
For your safety, this adapter has an internal circuit that monitors the plug temperature and communicates with the car to automatically set the appropriate 24 amp charging current. No need to manually set the current – simply plug it in! Cable length is 12 inches. We use a thicker cable for maximum efficiency and it also is more comfortable to grip onto when connecting and disconnecting it from your Tesla’s mobile connector. Made exclusively by EVSE Adapters.
