Tesla Gen 3 Wall Connector: Vs Gen 2 Specs, Walk-though, Opinion and More

Tesla's new Wall Connector is so up to date with current EV (Tesla) charging. In this video we are going to go through the specs of Gen 3, comparing Gen 3 to the older Gen 2, and a walkthrough of charging my model 3 on each.

Tesla Gen 3 Vs Gen 2 Specs, Walk-though, Opinion and More

You're missing some very important points:
1. On a high current device (like this charger), a heavier gauge cable is ALWAYS preferable. For the same amperage carried, the ENERGY LOST due to heat will always be less with a heavier cable. A heavier cable is also more durable. On that count, the generation 2 cable is superior to the generation 3 cable.

2. The generation 2 cable is six feet longer than the generation 3 (24' vs. 18') the extra length is useful if you have to park the car outside the garage..

3. The size of the wire used to connect the wall connector to your home electrical supply determines the maximum capacity of the charger: the heavier the wire, the greater the capacity. Once that is set, the car determines the maximum charging rate, not the charger. With the car in control, I see no point for having wi-fi on the charger. It's just something unnecessary to break and cause trouble.

4. The maximum charging capacity of the generation 3 is 48 amp. The maximum charging capacity of the generation 2 (when wired appropriately) is 80 amp. Charging at 80 amp is faster than 48 amp.

To me, the generation 3 wall connector is a gigantic step DOWN from the generation 2. I see absolutely no point in preferring a generation 3 to a generation 2. The "upgrade" is definitely not worthwhile.

Great video man! I want a Tesla model 3, I'm going to a special program that teach people with disability how to drive, in one mouth, after that I'm gonna start saving up for my Tesla! I have cerebral palsy I use a walker and wheelchair

[Greggory]

Great video! I have a Model X 2020 and I charge with a Gen 2 wall far it is so awesome.

just got my gen 3 connector up and running.. now all I need is my car!!!! delivery in 2 weeks. I am so ready.

Thanks...i have a Gen 2 charger but have been advise to upgrade to Gen 3 as it has a built in Earth breaker vs Gen 2 which you need to add an additional one.

The reason they cut the 3rd gen to 48 amps is simple, it's because they don't make cars that can charge at 80 amps anymore. The dual charger option on the Model S and X are long gone so there really isn't any reason to support it anymore since anyone who has a car that can support 80 amps prob already has a wall charger.

Fixing the 2 car, low cable length issue: Mount the charger on the wall adjacent to the charge points on the cars. eg, if you usually drive head first into the garage, mount the charger on the wall near to the garage doors.

If you want to mount the charger on the wall at the back of the garage, just reverse into the garage.

In these 2 cases, the cable will reach both cars.

Can get into the wall charger using a phone that's on the same wifi network of you know the ip address of it. It's helpful to have some IT skills for reserving an address for the charger

I like the Gen 2 units because one of my Teslas can charge at up to 70 amps. Also, if you have two units configured in a load-sharing setup, two Gen 2 wall chargers can deliver 40 amps each if both cars are charging, since they can split 80 amps between them. With Gen 3, they can only split 48 amps between them, so two cars charging simultaneously would each get only 24 amps.

Any chance cyber truck will be able to charge at 80 amps and then a Gen2 is better?

Well I ordered a Model Y and look forward to getting it this summer. I also decided to jump the gun and buy the wall charger now. It's sitting next to me here still unboxed and I got it a week ago. (Jan 27th, 2020) I did not know about the Gen 3 unit and wonder why Tesla didn't tell me about it. Don't know enough about electricity to figure all this out. I have a 60 Amp feed from my panel to my garage, and bought a 60 amp breaker for the garage. My cable is the 6 gauge 3 wire cable, so plenty enough. Should or could I swap out my 60 amp breaker for a 100 amp one for both my house panel and the garage? Won't that allow for faster charging? I seem to read you don't want to charge more than 80% of the battery capacity? I am confused.

So what do you think of the Nema 14-50 receptacle charging??

Taylor, Love this (I'm on the fence on which to buy) I have Tesla Solar and running on the power of the sun. THANK YOU!

[ItsFrankyD]

Thanks for the amazing video. I just bought my tesla I was wondering If I should buy a Wall Connector the newest one or buy a corded mobile connector. Any recommendations

[cominbaklife]

Does the gen 2 charger come with built wifi?

[mitchellbarnow]

Awesome comparison video! Supposedly you can connect several of the new chargers together wirelessly, while the old one requires hard wiring. I would love to be able to setup real start and stop charging schedules, but who knows is that will ever see the light of day.

[linklin]

Tesla’s software only lets the amps go to 48 amps any way

[Newalify]

1:10 please stop controlling my mind like this!!! I smiled and smashed the like button 😅

[yashc]

interesting... break out that scale! I suppose I can look up the weight diff. lol. I can't imagine buying a second charger unless I gor a second car

How do you not mention that the gen 2 and gen 3 wall connectors are not compatible? Whoever set their house up with one of each has made a questionable decision. You cannot load share between the two generations. So in effect, they're taking up nearly 140 Amps of their total 200 Amp service (if it's a newer house). I'm surprised an electrician would do this without putting a smaller breaker on the gen 2 charger. Even then it's still going to be 120 Amps.

When you install multiple wall connectors they should really be wired to load share so you don't overload your service maximum. The only advantage of the gen 3 is that you can load share without hard wiring the two connectors together. The gen 2 requires the use of a signal wire between the two units, which can be annoying to retrofit.

The gen 3 also supports load sharing for 16 units, the gen 2 supports only 4. Probably a non-issue for most buyers though.

My main concern with the gen 3 unit is that the cable is thinner gauge and owners have complained that it gets hot. At worst that's potentially dangerous. At best that heat is lost charging efficiency.

Finally, the gen 2 comes in a 24 ft variant that is much more versatile for spanning an entire garage than an 18 ft cable is.
