Wall Charger vs Mobile Connector

[aswa]

Wall Connector works better, but how much does it cost/ I am getting quotes from $869-$1900. Is it worth it than mobile connector?

The wall charger is about $400, the wiring is quite simple, however if your electrical box is full, where you need to add extra capacity, that’s where the expense adds up quickly. You will need a 50-60 amp service.

I have just the mobile connector on 110v. you get like max 10% overnight.

There are plenty of YouTube videos out there to learn a self install. Totally worth it, in my opinion. And it took me 5 years of EV ownership to want to install. Tesla's pedestal is super nice too.

Give it a go. We can walk you through it.

You can use your mobile charger with 240v. Dryer outlets come in different NEMA configurations (e.g., 10-30, 14-30). Determine which one you have, as this will dictate the adapter you need. Tesla offers various adapters for their Mobile Connector, including one for 3-prong (NEMA 10-30) and 4-prong (NEMA 14-30) dryer outlets. You may also find adapters from third-party manufacturers. If you want to use the dryer and charge your Tesla simultaneously, a splitter can be used. These devices automatically switch power between the dryer and the charger, preventing overloads and prevent you from having to keep switching plugs from dyer to mobile charger. You might be lucky and find that your dryer outlet is on a wall that backs up to the garage. If this is the case you can very easily cut a pass through to get to the dyer outlet. There are several YouTube videos that describe this. "Disclaimer" For long-term or complex setups, it's always recommended to consult with a qualified electrician to ensure your setup is safe, code-compliant, and properly installed.

Thank you for the info for all. My house does not have 240v, we'd need to hire a contractor to get permits and coordinate with the city to pull another wire from the pole. That's why I specified 110, but yeah for all who are reading go for 240v for sure.

What about solar?

We’ve used the mobile charger for 7 years, but we did find a dedicated line to the garage and changed it to 240v/20A since the wire could handle it. Running a new line to the detached garage was going to be expensive and complicated.

The key difference between the mobile connector and the Wall Connector is: Mobile Connector maxes out at 32amps. Wall Connector can do 60a. It all depends on how fast you want/need to charge your vehicle + how many miles you drive daily.

If it helps, the first 4 years I owned a Tesla, I used the mobile connector on a 20a/240 circuit. That was fast enough for us because we don't drive that many miles per day (plus we were in a condo and it would've cost a fortune to run new wires from the garage up into our unit). When we moved to a single family 2 years ago, we installed the Wall Connectors. We drive a little more on a daily basis but not much compared to the average US car owner, and having the ability to charge quickly at home is really nice for those times when you need it. That said, because it charges so fast, we only plug our vehicles in a 1-3 times per week (and mostly only to use Charge on Solar with our Tesla Solar system).

I installed our 2 Wall Connectors myself (with help from a buddy) and it was very straight forward. The cool part of having 2 on the same circuit is they can split the load when our 2 Teslas are charging at the same time.

Checking my understanding: you have two wall connectors running from one double-pole 60 amp breaker? Does "split the load" mean both vehicles charge more slowly than a single vehicle charging alone?

Yeah, Gen 3 wall connectors support Group Power Management which allows powering a set of WC from one breaker. If only one vehicle is connected, it gets full charging current.
"Power is distributed across multiple Wall Connectors to minimize charge time for each vehicle while making sure total power being drawn from your panel or a single circuit is within safe limits."

Note: WC uses a 60A max breaker and charge current is 48A max.

If you use the Tesla mobile connector at 120V, charging is super slow—think a handful of miles per hour of range, so it could take days to fill a Cybertruck from empty. With the mobile connector on a 240V NEMA 14-50 outlet (approx 8 kw), you’ll get a big bump—up to about 30 miles of range per hour. It’s decent for overnight charging but still slower than what the truck can really handle.

The Wall Connector, hardwired at 240V, taps into your house with thicker wiring and can deliver way more amps, charging much faster—about 1/3 faster than even the NEMA 14-50 plug based Mobile Connector) if set up for 60A. It’s also permanently mounted and a lot more convenient for daily use, especially if you care about charging reliability or need more juice overnight.

So: mobile connector at 120V = turtle, mobile at 240V = much better, Wall Connector at 240V = fastest and most hassle-free for home charging.

You can set the Wall Connector to whatever amperage your service will fit, but it does require 240v wiring. So it can be hardwired to less, like the Mobile Connector, if you have less available in the box or from how far you need to run the wire.

12a @ 240v will give you 2x what you can get from 120v, for instance, 24a will give you 4x, etc.

It goes up fast and don't knock something in-between; you really only need as much as you use on an average day to refill during your off-peak electricity price - because that average will get you back to full eventually.

Being able to get home with 0% and get up in the morning to 100% is nice, though ^-^

However, it's not the only way to do things! Lots of people use a lower amperage to deal with installation costs or their grid limits.

Even the Gen II Wall Connectors can powershare one circuit (up to a 100 amp breaker) with up to 8 Wall Connectors. Just make sure all the Wall Connectors are of the same generation.

This is one of the best features of the Tesla Wall Connectors over other brands, the units can talk to one another so the circuit can be fully utilized by multiple wall units without ever risking over-loading the circuit.

Is it 8? Manual calls out 4. https://www.tesla.com/sites/default/files/downloads/wall_connector_installation_manual_80A_en_US.pdf
Comparisons:

Gen 2: 4 units
Gen 3: 6 units

Gen 2: wired connections
Gen 3: wifi

Gen 2: 100A breaker max (80A max charge power) shared across all units
Gen 3: With individual breakers, can have any total power level and each can have a different breaker rating

Operation during loss of communication is different also.
