Our new NEMA 14-30 Gen 1 adapter lets you charge your Tesla Model S or X with Gen 1 UMC at 30 amp 4-wire outlets, commonly used for electric dryers in homes built after 1996. This adapter is also fully compatible with the JESLA charger for use with other EVs.

Just like Tesla’s OEM adapters, our adapter has an internal circuit that 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 18 inches.

As a bonus, we’ve made this adapter using our special 3-prong “universal” plug so you can also use it to plug in to NEMA 14-50 and 14-60 outlets at the same 24 amp rate. Tesla does not use the neutral wire, so by omitting the neutral prong our plug can fit 14-30, 14-50, and 14-60 outlets. The plug has a convenient handle making it easy to unplug, and safer by keeping your fingers away from the outlet.

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 2 UMC, it will not work with this adapter – choose one of the adapters in this category instead. If your vehicle has the Gen 1 UMC, you can use this adapter.
