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.

Which adapter do you need?

Tesla vehicles delivered prior to December 15th 2017 came with the Gen 1 UMC. All new Tesla vehicles come with the Gen 2 UMC. If you’re not sure, take a look at the charger cord that came with your car, and compare to the pictures below:

Visual comparison of Gen 1 vs Gen 2 UMC

If your Tesla came with the Gen 1 UMC, it will not work with this adapter – choose one of the adapters in this category instead. All 2018 and later Tesla vehicles use the Gen 2 UMC and can use this adapter.
