Our new NEMA 5-20 Gen 2 adapter lets you charge your Tesla Model 3, Model S, or Model X with Gen 2 UMC at NEMA 5-20 outlets. The NEMA 5-20 is a higher amperage version of the standard 120V wall outlet, and typically has a T-shaped slot on one side to accommodate both NEMA 5-20 and the more common NEMA 5-15 plugs.
For your safety, this adapter has an internal circuit that monitors the plug temperature and communicates with the car to automatically set the appropriate 16 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 vehicle’s mobile connector. Made exclusively by EVSE Adapters.
