Tesla Will No Longer Include NEMA 14-50 Adapters With New Vehicles

KB Electric LLC received an email last week to notify us of a change being made with the purchase of new Tesla vehicles. We wanted to share this information for better assistance with electric vehicle charging installation options that KB Electric LLC can provide for its Tesla customers. 

The gist of the email: New Tesla cars will not include a NEMA 14-50 adapter as “standard” equipment with the purchase of a new Tesla. This means that a customer can purchase the adapter separately, or they can opt for different home electric vehicle charging equipment (Tesla recommends that their customers purchase their Wall Connector for home charging).

Tesla now is referring to the NEMA 14-50 adapter as a “backup” option for charging, just like their Mobile Connector.

Tesla will continue to provide the NEMA 5-15 adapter with the Mobile Connector that comes as “standard” equipment with a new Tesla vehicle purchase. According to Tesla’s website, this is best left “in the trunk of the car as a backup option while traveling.” This is because…

The Mobile Connector utilizes your regular 120v household outlet, but only provides you with 3 miles per hour of charge time (for Model 3 and Model S), and 2 miles per hour charge time (for Model X).


What is a NEMA 14-50 Tesla adapter?

Let’s explain a little bit of what a NEMA 14-50 adapter is first.

Up until this week, Tesla vehicles came standard with a NEMA 14-50 adapter for home charging. These adapters fit into a NEMA 14-50 outlet, providing 240v on a 50amp breaker, with a maximum output of 32amps. 

These NEMA 14-50 adapters have different charging speeds depending on the Tesla model:

  • Model 3 – 30 miles of charge per hour
  • Model S – 23 miles of charge per hour
  • Model X – 20 miles of charge per hour


What Does This Mean For New Tesla Customers?

So now you’ve got your new Tesla and are ready to call your licensed electrician for home electric vehicle charging installation to charge your car. Since your Tesla won’t come with a NEMA 14-50 adapter…

You can still buy a NEMA 14-50 adapter from Tesla if you still wanted to go this route. KB Electric LLC is more than happy to install a NEMA 14-50 outlet in your garage for you to charge your new Tesla. 

The other option (the one that Tesla recommends) is buying Tesla’s Wall Connector.

Tesla’s Wall Connector is recommended by Tesla to be installed on a 60amp breaker in most home circumstances, and has maximum charging rates compared to the NEMA 14-50 adapter and the Mobile Connector. The Wall Connector has the following charging rates for its Tesla vehicles on a 60amp circuit breaker:

  • Model 3 – 44 miles of charge per hour
  • Model S – 34 miles of charge per hour
  • Model X – 30 miles of charge per hour
