Are there any real advantages in wall chargers?

Depends on how much you drive, in our case one mobile charger (230 V) is plenty for a 3 and a Y (both LFP).

My wall connector can handle more power but mostly it's just for convenience.

Wall connector is one fewer point of failure, and it’s a big one. I had a plug in EVSE nearly burn down my house, it melted the plug. You can get slightly faster charging with a wall connector on a 60 amp circuit (48 amp charging).

So if you are renter, just use the mobile charger. If you own your home, get an electrician to check the wire and breaker capacity, and a new receptical for the mobile charger. If your power goes out often, maybe a wall charger on the hope that Model Y has some ability unlocked to power your home.

Wall charger has a few extra "features" (you can do scheduling for EV's that can't schedule on their own) and they do metering so you can see exactly how much power is being used over a month/year. (which is not the same as what your Tesla will report as being used for charging). And of course faster charging. BUT for most people that park at home each night for at least 6 to 8 hours the mobile charger is good enough. I have both, My son's model 3 uses a mobile charger and really the only time it makes a difference is when he stays over at a friends in the winter and he comes home in the middle of the next day and then he needs to charge during the day and then leave again. He drives a TON though much more than I do. Other than that both cars are full the next morning anyways regardless of the charger.

Wall chargers is faster. Mobil limited to 24amps

I leave the mobile charger in my car for when I travel away from home. Superchargers are great. But they’re not ubiquitous. So having your own mobile charger (that you don’t have to remember each time, is one way to ensure that you can at least charge slowly almost anywhere at 120V.

Having collected a 26 Model Y Prem AWD today I found out in UK we don’t get the mobile charger with the car anymore. Just a CCS cable to plug in to whatever you have available public/home/work.

For Teslas, the TWC has a higher max charge rate, but the mobile connector is well mobile and works with both 120v/240v. I went with TWC to take advantage of tax and local electricity credits. However I'm fortunate to have free charging at work and around home. Used the charger less than 10 times close to 3 years. Mostly just before long rainy days or when we got heads up about blackouts. In retrospect a 240v plug with the mobile connector is all I need and cost less. Only tip for 240v outlets is to not plug and unplug constantly. Leave it plugged it until you get a different charger.

Why do you recommend not unplugging from the 240V?

Yes, you can set the fucking app to maximum amps and it will stay. Was using the mobile charger with a nema 14-50, 40amp circuit and in the morning the app set itself to 48 amps and melted my panel. Granted, I also had a wiring problem too, the breaker should have just tripped, but I had it all redone with a wall charger and 50amp circuit and set 50amps during the wall charger setup and now the app cannot be set any higher than 40amps (safety difference). I'm sleeping better.

Not true, it depends on the model. There's a table on the Tesla site with max amps for each model.

I have a Mobile Connector that lives in my car and Wall Connector in my garage for convenience and safety. I rarely use the MC, it’s there just in case.

The wall charger charges faster, is less messy as it can store the charging cable, and since it’s directly wired, you don’t have the issues that some have with their low quality outlets catching fire.

Mine says 32

Weird. I plug mine into my 50 amp welder circuit and I only get 24amp max out of the Mobil charger?

if you own your home you should get the wall connector. keep the mobile in your car for emergencies.

Convenience in which terms?

This is my conclussion so far. Anything you can do on the Wall Charger can be done in the Model Y itself (scheduling - reporting). So i kinda want to buy the Wall Charger but really havent been able to find a real advantage.

It's because the outlets themselves are typically not designed for many insertion cycles. The are expected to just be plugged in and left like dryers or ovens.

I've used a mobile charger on a 50A/240V circuit at home since 2019. I do have another mobile charger I carry around in the car, but hardly ever use. I haven't had any problems with the mobile charger as a home charging solution.

Guess it does give you more peace of mind havind a more "solid" system.

How is the WC more convenient and safer?

If you mess with the circuit isnt it also possible with the WC? Trying to understand if there is some real implicit extra safety on the WC.

Any specific reasons?

No, there is absolutely no real world benefit. Level 2 charges fast a few extra amperage isn't going to matter. You'll get a lot of replies saying it does - it's just people justifying their purchase. The car can schedule charging itself no real need.

If you buy an outlet designed for an ev you're fine

This is what i was thinking, havent been able to find a specific function or case that really justifies the purchase. I kinda want to, but havent found one.

go visit r/evcharging that is a better sub for electrical stuff than here but the primary reason is safety. The second would be more advanced controls if you need it for TOU, power limitations in your home electrical service, sharing power between multiple chargers, etc. It is just a way more robust solution.

If you do end up going with a regular outlet then I would recommend buying one specifically made for an EV The rumor going around in the one made for dryers aren't meant to have a bunch of plug and unplugs because they're static whereas an EV charger can be unplugged and replugged constantly

Thanks, ill check on this.

Ill check on it, thx.

The only caveat is that a lot of people on that sub are anti tesla and will suggest other chargers but the wall connector is actually a really solid option. I have 2 of them myself.

Just posted there, ill have this in mind.

This makes no sense. A dryer isn't used 24/7. It turns on and off depending on usage. Just like a car.

Your power company may have a special cheaper rate (per kWh) that you can get for EV charging. This usually requires a hard-wired wall charger. They usually don't allow this special rate for a 240-volt outlet as you could use that power for anything (not just EV charging). Other than that there isn't really an advantage to a wall charger versus using a portable charger.

It's just handy to have it right there on the wall whenever you need it. Mine in hardwired so it can deliver more power than the mobile charger. I can keep my mobile charger in my car and not forget it at home or anything like that, even though that has really never happened. Other than that there isn't much of a difference between the two.

Well if you're a really digging for excuses let me try to help you out.. The faster charging time it offers does mean that your car will be awake less and so that does end up saving you a little bit of energy overall. But it would probably take many years to be significant. The reporting the wall charger gives you is a little different than what the car reports. The car will only report what energy it used for charging, It will not include any energy used for preconditioning while you are plugged in, the wall charger will include everything. Technically you can install a wall charger using only three wires from your breaker box and if you install a NEMA 14-50 outlet you have to run four wires. But considering those three wires have to be a larger gauge you usually end up spending more anyways for the wall charger installation.

Yes this is true. There are some now specific to EVs. Some dryer plugs can melt. They are not all created equal. Also if you change out the plug yourself, go ahead and be prepared to use a (big) torque wrench. It is stout!

People can screw anything up. With the mobile charger, you add both a plug and outlet to the circuit, versus the wall charger which is directly wired. I’ve seen multiple issues where people have burned outlets and plugs, especially if they don’t get commercial grade ones rated for high capacity continuous use. It’s rare to see issues like that with wall chargers, at least when properly installed. It’s really just up to what you are comfortable with, and what works best for your situation. Neither option is bad. For me, I keep my mobile charger in the frunk, in case I need to charge on the road at camp sites when traveling, and use a wall charger at home.

I’ll check on this. Thx.

Mine is 48A

Load balancing. Charge multiple cars off one circuit.

I find it justifiable in the case of flex savings with our local utility company in which the costs goes from $.15 down to $.06 per KWH if used during certain times. I can then schedule it to come during that 3-4 hour window and charge only when it is at its cheapest. For the amount of miles I drive it made perfect sense, especially paired with the local rebates of free installation for me

The max the mobile charger does is 32. Or are you talking about the wall charger

I've had others tell me that used the mobile cable that they've had melting outlet or possible fire problems. There's someone that replied to your thread that it happened to as well. Wall connector is safer.

A dryer stays plugged in 24 /7. You're not constantly plugging / unplugging it wearing down the socket. The theory is they aren't made for that so can't handle the cycles an ev charger would

Ah, so it's the physical connection, not the actual electric cycles.

Thing is I don’t see how it’s safer. I guess people that install just the outlet tend to do that with cheap parts or contractors. Not sure how a well installed outlet is less safe.

Hehe that does help.

Safety from being a single connection to my electric panel and no question of the outlet for something that I will never need to remove. Convenience of it always being available and it being integrated with my Tesla Energy system (even though there’s currently a firmware issue!).

I tend to leave the 240V plug into the outlet but remove the mobile charger, so I think I am fine but thanks!

Since I got mine for cheap, from marketplace, I went for it. Super convenient for me to go home, plug in and rinse repeat.

I said the same thing and went cheap. Ended up with a melted electrical panel.

Do you know where you went wrong? Any component?

The fire was because of the wiring, but it wouldn't have happened if I had been able to set the maximum amps in the app and it had stayed. The wall charger allows you to set the max and the app will not go above it.

Can’t this be done from the car?

Probably fine

> If you buy an outlet designed for an ev you're fine If you plug and unplug it every day, you're likely to find it failing in a matter of a short number of years. The good ones are rated for a number of plug/unplug cycles in the hundreds. With 365 days in a year, you can burn through that pretty quick unplugging it every day.

The plug between those two isn't magic. It's contacts will wear out with repeated plug/unplug cycles, too.

> Level 2 charges fast a few extra amperage isn't going to matter. Makes a difference preconditioning the car in sub-0° F temps. The MY will use every last bit of 48A to heat up and if your charger isn't providing it you'll eat some of the battery capacity. It can be several % when it's cold soaked.

> But considering those three wires have to be a larger gauge you usually end up spending more anyways for the wall charger installation. When I looked, it was pretty close to a wash between the prices of a good EV rated outlet and outdoor box, and the difference between 8ga and 6ga XHHW-2 for a 75' run. Difference was in the neighborhood of $100. Granted, that's buying my own wire, not paying an electrician that adds whatever random markup they feel like. But also buying small quantity by-the-foot amount of wire and not a 500' or 1000' spool.

Except you generally leave you car plugged in for hours and once it's heated it's heated. The extra amperage will save you some time... Just not a lot. And think about it in terms of how long you're charging. Over night? Doesn't matter.

Yea and I should clarify to anyone reading that really only 2 of the 3 wires have to be the larger gauge for a wall charger. The 3rd wire (which is the ground wire) does not have to be the 6ga it can be the bare 10ga. The other big question is can you use 6/2 NM-B romex for this since most are rated for up to 60C temperature rating (and actually rated to 90C)? I know a lot of people do.

> The other big question is can you use 6/2 NM-B romex for this I'm no sparky but I don't think so. I certainly wouldn't. It's only rated to 55A at 60°. Putting a 48A continuous load on that is dicey imho, and as far as I understand it does not meet code. My run was a lot easier to run a conduit around part of my structure on the outside. Can't use the 6/2 NM in conduit for this. I also went with 8ga for my ground as my run is a bit long.
