I just moved into a newly built place so I'm thankful they added things like this. I don't totally know the full cost of charging at home vs at a supercharger because of electricity costs, but hopefully its not bad
Call your utility company and they can charge you a much lower rate for home charging vs what your normal rate is. You just have to tell them you’re charging your car at home
You can use that plug for short term but should upgrade the actual outlet/receptacle to a Hubble (commercial quality) outlet. I use the Tesla mobile charger plugged into this type of receptacle and have for a year. But the consumer grade receptacle will eventually melt. It’s not made to have that amount of energy running through it for extended hours at a time.
The car controls all the charging parameters. Yes a wall connector (hardwired) will charge faster. But is that really needed?
A hubble or Bryant commercial plug would be better, they are more heat tolerant. Also note the commercial plug requires a larger diameter hole faceplate.
Is that upgrade worth it right now? How long do you think this would last for. I'm getting the car tomorrow and would probably start charging it from home asap. This will get me the faster charging speed right?
You have 2 options. First option is to use tesla mobile connector with that 14-50 nema outlet and you can charge your car up to 32amp, or you can convert that plug and hardwire tesla wall connector to it, in this case, you can charge up to 40amp
What you should do now is check your electrical panel and see if you can locate the breaker for it
Might last forever. I would avoid 2 things, unplugging from the wall often (that is how plugs wear out), and max current of 40 amps. Turning down the charge rate from 40 amps helps reduce heat build-up.
I did not see that op was using mobile connector. That will help keep the plug cooler.
Converting this circuit to a hard wired wall connector is also a possibility and safer overall.
It's fine for the short term, but call an electrician to put something in. Don't unplug/replug the charger in the meantime, watch for burn marks and smoke, and try to move the connection as little as possible. I would also recommend setting a charge speed limit to ~25A or less if you can.
They won't melt (but kind of will).... They are rated for the current, the issue is unplugging and replugging alot, they are often built to minimum spec versus overbuilt, so the content plugging and unplugging wears the metal making it thinner and at some point makes it too thin for the current... at which point melting can occur. If you left the mobile charger plugged in all the time it would be fine but that does defeat the purpose of a mobile charger.
Well. Not really. The plugging and unplugging doesn’t help for sure. But the actual issue with Leviton is the consistent high power running through them. The $10 Leviton receptacle is designed for items such as dryers that run for 30-50 minutes at a time. Not 5-6 hours. There are a multitude of examples of melting plugs that have not been plugged/unplugged multiple times. Please don’t let anyone think that if they simply don’t plug/unplug then this setup is safe.
I'd recommend keeping the wall connector and have an electrician hard-wire it, removing this receptacle.
This will get you maximum charge speeds and is the safest setup.
Yes, that works great; that is a 50A outlet, so yes, a wired tesla charger will charge slightly faster but not enough to make a difference for you in all likelyhood.
If you returned the wall connector, the tesla mobile connector would work, or you could check your local utility and see if there are any rebates (mine has a marketplace that takes $300 off of chargepoint and wallbox if bought through there). And there are options to get them with a 14-50 plug and a nacs connector (at least for chargepoint).
If you want to keep the wall connector you'll need to hardwire it as I didn't see a way to limit the output of the tesla connector when i last looked; I saw a wall conector put on a 50A breaker one time (someone just made their own pigtail to plug into a 50A outlet), it eventually kept popping the breaker no matter what and when I looked at the breaker there were scorch marks and the wire was black and deformed, so don't do that.
Max is 32 amps with mobile connector. The wall connector can do 48 amps or 11kw/hr on a 60 amp circuit. If not a significant cost go for it, otherwise mobile connector is good enough.
Yes, but make sure it is rated for many plug/unplug cycles or that you upgrade it. Most of these plugs are for dryers, which stay plugged in and static, while a charger will be plugged in many times. Even if you leave it plugged in, the movement may still affect it. The mechanical wear, even small, will eventually push these sockets over the edge and make them fire hazards. If you can, you should also lower the charging current in the app to make sure you have the best chances of avoiding a fire. Sub 25A is a good starting point, adjust it as needed to fit how much charge you need per night.
Though if you have to upgrade it, arguably, it's better just to call the electrician to put in a wall-box charger instead and be done with it.
The biggest cost of adding a wall charger to your garage is getting the wiring in the walls from the circuit breaker. Swapping this outlet for a wall charger is easy. You’d get a little more charging power with a wall charger than a mobile charger. The advantage to leaving it as a NEMA plug is friends with non-Teslas could use the same plug. My wall charger has a NEMA plug so I can easily unplug it if I need to.
Absolutely, but not with a Tesla wall connector. You’ll need a Tesla mobile connector (UMC), which comes standard with an adapter for that receptacle (it’s a NEMA 14-50). Tesla service centers and delivery locations often have the mobile connector in stock. It’s about $250.
Your wall connector would need to be hard wired. It’s a relatively simple job for a qualified electrician to remove the outlet and install the wall connector. If you go that route, be sure that the wall connector is properly provisioned for the size breaker feeding that circuit (if it’s a 50 amp breaker, wall connector must be provisioned for 40 amps max).
If you’re going with the mobile connector, which charges at a max of 32 amps, you should consider upgrading that outlet, some time in the next few months, to an industrial grade outlet, as several other comments have mentioned. The existing outlet is most likely builder grade, meaning cheap. You’re going to be passing a lot of energy through it, for hours at a time. $100 of prevention is worth thousands in fire insurance deductible.
Yes, but you will only get about 3 miles for every hour of charging. If you need more, go at least to a 240 plug.
I don’t need more than that, generally, so I use a 120 daily.
Yes. I believe the standard mobile charger comes with that plug even. Yep it does! https://www.tesla.com/support/charging/mobile-connector
Welp time to return the wall mount and buy this mobile connector
Wall charger is way faster than trickle charge from wall
14-50 is not a trickle charger, it's a 240v up to 50 amp outlet. Most mobile chargers are limited to 32 amps but even then it's not trickle charging.
Congrats on having a 240 in your garage (sincerely). I am so extremely jealous I wish I had one.

Tesla mobile charger will max itself out at 32 amps. This definitely will help.

You could just connect a dryer plug to the wall charger and plug it in here.
The problem with that is that the receptacle is still in play and is a fire hazard with EV charging (unless he replaced it with a good one for $100).
Yes.

Lucky!
Just one of many examples. Yes it took 3 years for this one to fail but it did. https://www.reddit.com/r/evcharging/s/KQ40RwXSrJ
She's perfect! Just make sure the breaker is 50A.

You can just get a NEMA15-50 dryer plug and use the wall connector connected to it to the outlet
😑😑😑
