I have the standard Tesla Wall Connector for my Model Y LR to get the max 48 amps out to get roughly 43-45 mph on charging.

I wonder if Tesla will sell a faster more capable updated Wall Connector to speed up home charging for the upcoming Cybertruck if it truly has a much large battery pack, any thoughts or are we limited by our home circuit?

I never got a special charger since I work from home. I only get 5 mph on a stage outlet on my Y. Does anyone with an electrical background know if it will still be 5 mph with the Cybertruck?

It has a bigger battery so can hold more juice, but it also weighs more so the miles per kilowatt is probably lower?

If you had the Gen II Wall Connector, it would charge up to 72 amps if placed on a 90 to 100 amp circuit, if some earlier Model S/X's were using it because they actually took advantage of that.

I don't know why they reduced the capacity in the Gen III Wall Connector, but it was likely to save costs on cable and wire size since the likely over 95% of the owners used it for a Model 3 or Y. Later, even the Model S/X charging current draw was reduced if I'm not mistaken, so again very little usage of the full capacity of the Gen II unit.

But with the Cybertruck's range and speculated battery sizes, I too have wondered the same thing and would be surprised if they did not increase the AC Wall Connector charging throughput.

However, given that a Model 3/Y can charge from 10 to 90 percent in a little over 5 hours using the 48 amp capacity (on a 60 amp circuit), one could be fairly in the 'ballpark' estimating that the Cybertruck battery size will be typically double the Model 3/Y or slightly more. So, if they did nothing to the wall connector and put the same AC charging throughput in the Cybertruck as what the Model 3/Y has, it would recharge from 10 to 90 percent in roughly 10 to 14 hours maximum, depending on the battery size.

For some people this may be fast enough, because overnight every few days would get it done. But I personally hope they put faster AC charging throughput in the Cybertruck, and I hope that the Cybertruck will take advantage of the Gen II wall connector's max charging speed/current. Or, as you point out, they could also come up with a more robust new Wall Connector altogether, for Cybertruck owners. I would be totally interested in that as well.

The Supercharging throughput of the CT could be different, and that is measured with just power of the charging throughput instead of current (i.e. 250 Kilowatts or 250 kW). It will also be interesting to see what CT supercharging speeds are experienced. I think with 250 kW the Cybertruck will still charge fairly quickly, because while the larger battery intuitively would take longer, the full 250 kW max rate can be applied for a greater portion of the charging cycle curve, in such a larger battery. I've been discussing V3 superchargers, but of course with V4 I understand we'll get even more throughput. So we'll just have to wait and see.

Not sure if you were aware that CT's will be using V4.

If I were to place a bet I’d expect 80 amps for 19.2 kw draw with a new version of the wall connector. Cadillac Lyriq is the only one I know off the top of my head that offers that as an option and that’s for a 102 kw battery. Guessing a 400 wh/mi usage that puts it at a charge speed of 48 mph which is in line with the same mph charge rate as the 48 amp charging for 3/Y.

I'm hoping a new "Cyber Wall Connector" includes V2H.

Same, I was always hoping to see that and planned for it. That’s why I’ve used mobile connector 100% of the time since I got my M3 and didn’t buy the wall connector. Reading so many people say that V2H would eat into power wall sales that would keep Tesla from doing it has put a damper on the excitement. Until Tesla says one way or another we will just see!

If they do release an updated Wall Connector I’ll keep the current one for my wife and her Model Y and have the newer one installed on the side of the garage since the Cybertruck won’t fit in the garage.

Most likely any V2H through the charging port would require a Powerwall installation.

72 amps output would require an 86 amp breaker. So probably a 100-amp breaker.

The wall connector is not a charger. The charger is in the car, and it is Tesla that reduced what the wall connector can deliver. All cars are limited to 48 amps right now.

it is true that the number of miles gained per hour is dependent on the efficiency of the vehicle so the CT is like to get 1/2 to 2/3 what a Model Y gets, maybe 22-30 miles per hour at 48 amps.

no one knows anything else except that the CT will have a higher voltage architecture.

Makes sense, maybe they will unveil their Gen 3 Powerwall and they should qualify for the Tax credit as well.

I have the Gen II Wall Connector on a 100amp circuit - bring it on! :)
