Our new NEMA 6-20 Gen 2 adapter lets you charge your Tesla Model 3, Model S, or Model X (with Gen 2 UMC) at NEMA 6-20 outlets. These types of outlets are commonly found in motels, used for the room air conditioner.

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.

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:

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.

    I keep getting an error code when I use this adapter. And it charges slower than my wall outlet.

    Slightly more expensive than the Tesla adapter, but not a huge amount. Also, the Tesla one was backordered, so I went with this one. I’m not an electrician but product looks very sturdy and well built. Very happy.
