This review focuses on the intricacies of different Tesla chargers. How to quickly charge a Tesla in your own garage will be discussed below. The manufacturer has included a proprietary charger as part of the basic package, but there are other interesting options.

The Tesla Mobile Connector (slow- and medium-speed charging) and the Tesla Wall Connector (charges fast) are differentiated for residential use. Other charging stations are also compatible with Tesla using an adapter. 

Tesla Mobile Connector vs. Tesla Wall Connector

The Tesla Mobile Connector (TMC or UMC) is a Level-1 charger that comes with the kit. However, you should understand that the regular charger will charge the battery very slowly. Only about 3 miles of travel after 1 hour of charging, which is usually not enough.

Note: Level-1 devices are those that plug into 120-volt outlets. Level-2 devices are those that plug into 240-volt outlets.

Tesla Wall Connector (TWC) — refers to Level-2 chargers and charges the electric car much faster. The units of power measurement are kilowatts. You can also see the amperes in the device specifications. A kilowatt is equal to the product of amperes over volts. 

How to speed up Tesla charging? Increase the number of kilowatts in the charging station.

To begin with, it is worth distinguishing that Wall Connector and Mobile Connector are both Level-2 type chargers, nevertheless they are different devices. Due to the operation from a 240-volt outlet, the Level-2 equipment is able to deliver more power, respectively much faster to charge an electric car, sometimes up to 9 times faster, compared to the slowest chargers. It is also called HPWC (high power wall connector).

The Gen 3 Wall Connector is a stationary charging station. It should be installed by a professional. The equipment is connected directly the power grid and not to a socket.

Wall Connector equipment is suitable for indoor as well as outdoor installations. It can be used to reliably recharge Tesla Model 3, Model S, Model Y and X models.

Different Tesla models have different batteries, so the range after a 1-hour charge will vary, about 25 miles and sometimes more on some models.

The current 3rd-generation TWC was released in early 2020 and has a lower 48-amp capacity than the previous generation (80 amp). However, don’t be too upset, because most Tesla’s released today have a 48-amp AC input power limit. This means that by using the TWC, you are providing your electric car with maximum power.

TWC gen 2 vs. TWC gen 3

There are two versions of the Tesla Wall Charger on the market—Gen 2 and Gen 3 . The main difference between the two is the Power Delivery (PD) feature. The Tesla Wall Charger Gen 3 has PD, which means it can charge your car faster.

The other difference is the faceplate. The Tesla Wall Charger Gen 2 has a white faceplate, while the Tesla Wall Charger Gen 3 has a black faceplate.

Both versions of the Tesla Wall Charger come with a power cord and a cable holster. The gen 2 power cord is about 6 feet long, and the cable holster attaches to the wall charger and holds the power cord in place.

The Tesla Wall Charger Gen 3 also comes with a 24-inch connector cable—longer than the 18-inch connector cable that comes with the Tesla Wall Charger Gen 2. The connector cable is flexible, so it’s easy to move around.

Alternatives to the Tesla Wall Connector

Customers of note some of the disadvantages of the TWC Gen 3 (thin cable, short length of 18ft.) and therefore choose alternative models that deserve respect. 

How does a charger with a J1772 connector charge a Tesla? Easy. In the trunk of every Tesla, you’ll see a J1772 adapter, which solves the compatibility issue perfectly.

Quite often electric car owners choose something else instead of Tesla Wall Connector equipment. There are several simple explanations for this – a longer cable to connect, built-in wireless interfaces provide faster connection speeds, the ability to work from a more powerful outlet, etc. There may be other nuances as well, such as price or warranty period.

Best EV Charger for Tesla

Tesla owners have a number of choices when it comes to EV chargers. The best one for you will depend on your needs and budget.

The Tesla Mobile Connector with NEMA 5-15 Adapter is the simplest option. It plugs into a standard 120-volt outlet and provides 12 amps of power, which is enough for most charging needs.  If you need more power, the Tesla Mobile Connector with NEMA 14-50 Adapter is a better choice. It has a higher amperage rating and can be used with 240-volt outlets (up to 32 amp for the TMC).

The Tesla Wall Connector gen 3 is the most powerful option, providing up to 48 amps of power (or 80 amps for gen 2). 

If you don’t have a Tesla, there are a number of other great options for EV chargers. The JuiceBox EV Charger is our top pick. It has the highest power output of any non-Tesla charger, providing up to 40 amps.

If you’re looking for a smart charger, the ChargePoint Home Flex EV Charger is a great option. It has a built-in timer and WiFi connection, so you can control charging remotely.

The Wallbox Pulsar Plus Level-2 EV Charger is another great choice, with a high power output and a compact design.

Finally, the Grizzl-E Duo EV Charger is an affordable option that’s perfect for basic charging needs for 2 cars. It’s perfect for high-power charging needs or when multiple vehicles need to be charged at the same time. It doesn’t have any advanced features, but it’s very reliable and durable. 

Whichever charger you choose, make sure it meets your needs and budget. With the right EV charger, you can enjoy a convenient, reliable charging experience.

EV chargers are an essential part of any electric vehicle owner’s life. Whether you have a Tesla or another electric car, it’s important to have a charger that meets your needs.
