Tesla Wall Charger Vs. NEMA 14-50 (In-Depth Comparison)

Last updated on April 18th, 2023 at 11:18 pm

One common burden with EVs is when it comes to charging the automobile. Just as there are different models of electric vehicles, there are also various models of car chargers.

Often, it is better to make a vivid comparison between two suitable electric car chargers to get the best charging solution. 

This article contains everything you need to know about the Tesla wall charger, the NEMA 14-50, and the most suitable for charging.

The Tesla wall charger is far better because it finds applications in various Tesla models. The expensive cost of the Tesla wall charger is already a pointer to the fact that it holds more value and quality. However, in any case, the NEMA 14-50 is an equally fantastic alternative.

Should I Use a Tesla Wall Connector Or a Nema 14-50?

Tesla Wall Charger vs. NEMA 14-50

For the best charging experience, the Tesla wall connector is a better choice than the NEMA 14-50 electric car charger. 

The above statement is only absolute because the Tesla wall connector is a better recommendation than the Nema 14-50. 

The Tesla wall connector is a very powerful and fast charger guaranteed to gain up to 32 mph per charge.

The aesthetic and clean look it provides to your home is a view to behold. 

Not only are you assured of a faster charge, but you can also be sure to go a long mile with the Tesla wall connector.

If you drive more than 100 miles daily, I’d rather you use a Tesla wall connector. 

Therefore, for a faster charge with assured charge power, you should opt for the Tesla wall connector instead of the NEMA 14-50. 

In addition, the Tesla wall connector is recommendable for virtually every Tesla model. Nevertheless, it is worth noting that each Tesla model varies in how fast it will charge. 

However, since the Tesla wall Connector is a better option, you cannot ignore the fact that it is more expensive. You will have to pay over $500 for the Tesla wall connector. 

Note that the NEMA 14-50 is not a bad option for charging your Tesla vehicle. The NEMA 14-50 electric car charger is a better option for the Tesla Model 3 standard range.

In conclusion, the Tesla wall connector is a better option for charging as per recommendation.

However, many factors can change the narrative making NEMA 14-50 a better choice.

Tesla Wall Charger vs. Nema 14-50; Which Is Faster?

The Tesla wall charger is slightly faster than the NEMA 14-50 electric car charger. Tesla wall chargers will give a minimum standard charge rate of 50 amps which is truly remarkable.

It will amaze you that previous models of Tesla wall chargers could charge at 80 amps which is a high rate for NEMA 14-50.

It is possible to have such a high charge rate as Tesla models vary. The NEMA 14-50 electric car charger comes with your vehicle on purchase, but you.

In fact, on charging, the NEMA 14-50 electric car charger will charge your vehicle 20 percent slower than the Tesla wall connector.

Since the NEMA 14-50 charger charges slower than the Tesla wall charger, it is best used for an overnight charge.

Note that, aside from charging fast, the Tesla wall charger will yield a better amount of charge to the car battery.

It is the common advantage that comes with fast chargers. The NEMA 14-50 can only muscle up a charge of 40 amps of current for charging your vehicle.

Although the charging rates are comparable, the difference is obvious in their charging speed. 

So, while the NEMA 14-50 charge can move the car at 25 mph per charge, the Tesla wall charger power will offer more charge. 

The Tesla wall charger on a full charge can move the vehicle at 32 mph per charge with all things equal. A preferable charge for traveling above 100 miles per day.

So, no matter how comparable their charging speed is, the resultant outcome of the individual charger is quite obvious.

Can a Nema 14-50 Connect To a Tesla Wall Connector?

Connecting the NEMA 14-50 to a Tesla wall connector using certain accessories is possible. However, such a connection is entirely at your own risk.

Usually, the connection of the Tesla wall connector is such that it is connected directly to the electrical wiring of the house.  

This way, you can easily connect the NEMA 14-50 outlet to a 50A circuit wire connected to the Tesla wall connector terminals. 

Also, you can get a short cord equipped with the capacity to handle current from the wall connector. The cord should have a plug for NEMA 14-50 with which they can be connected.

From the description, the whole connection is more or less similar to the connection of an adapter charger. In simple terms, using a recommendable adapter will do the trick.

However, the combination of the NEMA 14-50 to the Tesla wall connector doesn’t give any supercharging.

Contrarily, it may become the foundation of the charging issue for your car. In any case, using a single model-type charger is professionally advisable, better, and safer.

Usually, Tesla models have a preferable charger recommendation that suits the model best.

The use of a different charger may be the cause of an emergence of a particular problem for that model.

If that is the case, how much more of a combination of two different modeled chargers? 

So, if you are to use the Tesla wall connector, an excellent choice; suppose it is the NEMA 14-50, good and fine. A combination may not necessarily be harmful, but it is not professional. 

Tesla Wall Charger vs. Nema 14-50; Cost And Durability Comparison

The Tesla charge is more expensive than the Nema 14-50 charger on the normal note. Tesla costs over $500 to the price of a Nema 14-50 corded automobile charger.

On the other hand, the overall cost of installation is another cost to bear when talking about the Tesla wall charger. 

Due to other required accessories, you could be counting about $2500 and above for installing the Tesla charger.  

Note that you may likely suffer other costs during installation depending on how few factors. 

The installation cost will vary depending on your car’s power source and outlet distance. 

However, it is not the case with the NEMA 14-50 EV charger, which is much cheaper than the Tesla wall charger.

The cost of installation, as well as the accessories, are a lot cheaper. The cost of purchasing and installing a Tesla wall charger far outweighs getting a NEMA 14-50.

The table below compares the Tesla charger and the NEMA 14-50 EV charger in terms of installation cost.  

Note that the individual cost of the below accessories is more expensive in terms of the Tesla charger.

In terms of durability, the Tesla wall charger and the NEMA 14-50 charger are durable. They are both built to last the test of time during use. 

However, just like other normal types of chargers, certain factors can temper the durability of the chargers.

Few factors can temper the durability of EV chargers.

  • The electrical power source.
  •  Nature of the wiring system. 
  • And the supply of current.


Nothing is more important than using the right charger model for your Tesla whenever it goes low on charge. 

The Tesla wall charger and the NEMA 14-50 EV charger are two comparable good chargers that can serve the changing needs of your vehicle.

However, as per speed, quality, and professional recommendations, the Tesla wall charger is a better choice.
