Wall mount vs 220v

[Dvldogg05]

What would be the difference l? Do I need a wall charger unit if I have a 240v? Will it charge any faster or no

I don’t have my CT yet. So this is based on my 2023 MY performance.
Both chargers and their speed of charging depend on the amperage.
I’ve used both as I have a few buildings on my property.
The mobile charger, when plugged into a 30 amp, 220 (dryer plug), charges at 25 (8-9%) miles per hour on average. A 40 amp, gets it closer to 32-33 (11-12%) miles per hour of charging. My wall charger, on a 50 amp, is getting 45-48 (15-16%) miles per hour of charging. I looked into swapping the 50 amp to a 60 amp, but it gains just about 3-5 miles per hour of charging, or about 16-18% max per hour of charging.

The CT battery is larger. I haven’t crunched the numbers to compare.

No, you don’t need the wall mount. But most 15-50 outlets are the cheap Leviton brand and they’re made for light duty use and have proven to wear out/ get hot and melt or start on fire.

Make sure your 15-50 is in good condition, or just replace it with a Hubbel or better with properly torqued lugs. And don’t unplug your charger often, which wears out the outlet pins.

I mean i have to unplug everyday right lol. Or.you mean from the wall

And just to point out that the Cybertruck is about half as efficient as a Model 3 or Model Y. So for a given number of miles driven, it will take about twice as long on a given L2 charger.

I've charged my Model 3 the last couple of years on a 240v/20-amp circuit. That was adequate, barely. But would have been a struggle on the CT.

With that in mind, I recently upgraded that circuit to 40-amps. Which means my Model 3 is now charging in about half the time it used to; and the CT will charge at about the same speed as the Model 3 spent the last couple of years charging at.

The Tesla Wall Connector is the more robust solution for a whole host of reasons. If you already have a wall outlet, it's typically a simple matter to replace it with a Wall Connector and eliminate the most common point of failure/problems, the plug and outlet. If you reuse the wire you will have to de-rate the Wall Connector to whatever amperage the existing wire can handle (probably 40 amps).

NACS is the continent wide EV charging standard and EVs are on a path to becoming the norm, not the exception. So it makes a lot of sense to have EV charging where you park. If you sell the house down the road, the Wall Connector will distinguish your house from all the others that don't have EV charging. I also like the built-in cable management of just putting three loops over the top of the Wall Connector vs. the Mobile Connector hanging from a wall outlet, that's just not as tidy.

The Wall Connector on a 60 amp breaker can charge 50% faster than the Mobile Connector (48 amps vs. 32 amps). If you decide to use an existing wall outlet, check it for heat buildup after charging for a couple of hours, the Mobile Connector does have built-in thermocouples to detect excess heat at the plugs themselves, but it can't detect excess heat at the outlets wire terminal connections very well.

With quality hardware and best-practices installation, either will work fine (assuming you generally don't need the 50% faster charging), but the Wall Connector is superior in every way that matters.

From the wall. The Tesla connector to your car is designed and tested for a large number of cycles.

Most standalone residential wiring in the US is 240/120V. Apartments or condos may be using commercial solutions and they can be 220V.

Power is the voltage times the current. If using the mobile connector, the difference between 220V and 240V is 1,000W or about 2 miles per hour charging.


I've used a NEMA 14-50 (240V 50A)socket for 6 years and it works great with the Mobile Connector. I got an extra Mobile Connector, so one stays in the vehicle and the other stays in the socket. With 3 Teslas and 2 plugs, I've now get 5 Mobile Connectors. I'm always charged overnight.

The Wall Connectors, if fed by a 60A breaker and capable circuit will allow charging to increase from 32A with the Mobile Connector to 48A with a Wall Connector. It may sound like a significant increase, but there are seldom times that you need that much.

I'm currently charging on a 240V 30A circuit and I'm full by the morning.


Even if for some reason that you don't get full overnight, it nominally doesn't matter, it's really uncommon to have two 300 mile days in a row, so you start out the second day a little low.
And you can always augment at Superchargers.
