Best Extension Cord for Tesla Charging – [Safe Charging Picks]

If you know how long is the Tesla charging cord, you can probably admit that it is pretty short. But fortunately, you can eliminate charging inconvenience with the best extension cord for Tesla charging.

However, what makes an extension cord good?

A good extension cord for Tesla would be one that perfectly increases the Tesla charging cable length, is durable, boasts safety features, and has correct amperage and voltage ratings.

So, which extension cords meet all these critical criteria?

Well, there are not that many. And if you want to know which ones excel in these factors, you should keep reading.

Is It Ok to Use an Extension Cord to Charge Tesla?

So, can you use an extension cord for Tesla charging?

You can safely use an extension cord to charge your Tesla at home. However, that statement is only valid for the extension cables directly compatible with Teslas.

The thing is, charger cables are not as simple as you might have thought. Many crucial factors determine whether they are safe to use.

For example, you have the wire gauge, safety mechanisms, and proper amperage and voltage ratings.

If one extension cord satisfies all the crucial factors, you can safely use it to charge your Tesla. In fact, you can even use it for Tesla level 3 charging.

What Kind of Extension Cord Do I Need to Charge a Tesla?

You must keep some crucial factors when choosing a Tesla extension cord for charging. Want to know what they are?

Let’s take a closer look at each of them.

Length of the Cord

First and foremost, you need to consider the length of the cord. Remember, you are getting an extension charging cable to increase the distance between the Tesla and the charger.

So, it would not really make sense to get a short cord.

However, you would not want to get an extra-long charging cord. Why so?

A super-long charging extension will be a tripping hazard. In short, the line needs to be long enough to let you easily connect the Tesla to the charging station.

Amperage and Voltage Ratings

Another critical factor you need to consider is the amperage and voltage ratings of the charging cord. These two will dictate the power of power you can safely get from the extension cord.

Most Tesla has a minimum requirement of 40 amps. And typically, the voltage rating of the charging stations, unless it is a Supercharger, will be 240 volts.

So, the safest option would be a Tesla extension cord 240V with a 40A rating.

Build Quality and Weather Resistance

The durability and weather resistance of the cords play a crucial role. Usually, you will keep the extension cable exposed as it will be longer than the original charging line.

So, it will wear out quickly if it cannot withstand extreme weather conditions.

Regarding durability, you must consider that the charging process will generate heat. The cable will not last long if it is of low-quality materials.

Therefore, keep the build quality in mind before making a purchase.

Built-in Safety Features

Safety features should be the number one priority for all electrical equipment and accessories. Some of the safety features are overcurrent protection, grounded plugs, and surge protection.

In fact, some of the cables will even have additional safety features to pair up with a portable charger for Tesla.

If you use a Tesla extension cord without these features, you will be putting yourself and the EV at risk.

An accident can happen at any time! And when it does, the internal circuitry and the charging station can get damaged permanently.
