Thank you Sir. I just purchased my Model Y and I live in an apartment. I have been researching a short term over night solution for charging. Your video has helped me understand the correct gauge of extension cord to purchase…. Thank you, you are appreciated… God bless…
This is a good experiment, thank you for posting the video. I'll make sure and bring a 12 gauge extension cord with me when I visit my Dad's house. He has no external accessible outlets, so I'll have to run an extension to an outlet inside his shop. This test makes me feel good about wiring my own NEMA 14-50 outlet only 3 feet away from my 200amp breaker box.
Good info! I went and got a 10 gauge 25 foot cable, to enable me to charge 240V using a NEMA 14-50, at a camp site. I won't carry it with me everywhere, as minimizing weight is the key when driving. I debated 12 or 10 gauge, but I like to be extra careful and not let a cord get hot. The key is to get as close as possible, to reduce resistance.
12 gauge is good for 120 volt, but 10 gauge is needed for 240 volt. The weakest link is actually the electric socket you're plugging into, rather than the extension cord.
great job showing power loss in cable. my contracting cords all all 10 ga . there is times i run 200 ft to generator and run power tools. love how tesla shows voltage at car .charge a friends bolt on 120V . wish you had IR camera to show heating on 14 Ga cord . also you are paying for lost power on cord. and the heating on cord will shorten the life of the cord. with EV I tell everyone 12Ga or better . shorter better . never take ground off cord. . same with all brands of EV. if you are stuck at old house 14ga with fuse best to force slower charging . like 9 amp . try to keep volts at car 115 or better . this in continuous load you don't want a fire or damaged wiring . anyone not sure just ask electrician to be safe.
Thanks for the amazing video man! If I were to ever get a Tesla I would definitely need to charge through an extension cable so it's good to know of what to expect 🤘🏾
I used rv extension cord for 6 months because i couldnt easily reach the car eith mobile connector cord. It worked but there were overheating problems and eventually charging became failure prone with errors and cancelled charging. There were errors of gfci breakers. I replaced mobile connector and errors went away. Ill save extension cord for emergency
Dave if you looking for video suggestions, I was wondering if you could test the efficiency of AC charging from 15 amps up to 48 amps to see which one is the most efficient. I am curious if there is a sweet spot.
One question, if I use the 50amp nema 6-50 extension 75ft from the third floor to the first floor there is a 25ft drop from top to bottom will there be any problems? I set the charger to 32amp, it will only use 70%, the extension is a 6 cable that can withstand 50amp.
very nice video! I live in Switzerland where standard outlet is 230v. Would it be possible to charge my tesla with a 100m (300ft) cable? I know, weird request, but I live in an apartment with indoor parking and the cable has to be that long... It would be one cable with no plugs in between.
Hi. Is the tesla 110v charger plug waterproof for when it rains and snows? Would the extension cord be ok in rain and snow? I use the supercharger network and level 2 at work, but for home i would just like the 110v setup to keep the battery warm and no % drop over night. I'm not worried about adding %
You should keep the plug and sockets dry always. There is a product now I’ve seen at Home Depot and Lowe’s ( hardware stores in the USA) that is a rain cover for extension plugs found in the Christmas stuff.
Never use an extension or adapter. Never. It can be rally bad and you will heavily increase the risk of a fire, either in the cord connectors or in the wall outlet or in your house. Do a proper installation by an electrician and use a proper permanent charger. That cable charger is ONLY to be used in rare occasions where there are no real other alternative - emergency like. That, and the wall outlet, is not made for regular use.
Sorry but you provide no evidence of why it is "rally bad". An extension cord that is in good shape is not dissimilar to the wiring in your wall. Both are 14/2 copper with ground. Wall outlets are definitely made for "regular use". Nothing will last forever, sure. Are extension cords a trip hazard? Sure. But so is the charging cord itself, even a nice permanent wall mounted one.
@@ewicky There are several reasons: * Every extra connection is an added fault point. Connections will be worn, oxidize and more. That is a potential hazard. * The longer the cord, the higher the risk of overload without circuit tripping. So let's say you have a breaker for 10A, but you could end up using 15A without tripping the breaker and thus providing huge stress on cords, connection points and such. * Wall outlets are NOT made for high currents for long periods of time (hours and more). They are made for low current use for longer times or high current use for short time, like water boilers and micro wave ovens. * Wall outlets are NOT made for pulling and putting in a plug over and over again. * When testing for instance Schuko, they use a brand new socket and load it for an hour. Some more tests are done but in general, that's about it. Not an outlet several years old with oxide and wear. * The cables from the socket is for most people old or very old, and you have no idea of the shape of connection points between socket and breaker. www.elinstallatoren.se/2020/09/allmanbruksuttag-av-schuko-typ-ar-for-nodfallsladdning/ www.elinstallatoren.se/2019/02/den-farliga-laddningen/ chargingshop.eu/blog/is-it-safe-to-charge-your-ev-from-regular-16a-outlet/
If you had a 10 gauge cable, would you be able to charge 120V @ 16A with a 5-20 outlet? I have a 5-20 in my back yard but we'd be looking at a 50 foot run to the driveway area...
There are some online wire gauge voltage drop calculator you can use. Your case seems fine to me. I'm not responsible of your installation of course :)
Your plug probably needs work, try another plug on a different circuit breaker. Can you plug the mobile connector into the offending outlet and does it work?
@@evdave528 I got it fixed. Who is the cable itself even though it was brand new and heavy duty but I end up buying yellow jacket cable and it works like a charm
I know but this was a regular house current test, most homes in North America use 120 volts AC as standard. When traveling you are more likely to find 120 vac
What kind of MPH were you getting Kw is a nice technical number but MPH actually tells most owners more useful info. And I hope you didn’t buy all those cords. But thanks for the tutorial. I’m lucky at our SIL/Dau home the found and unused 5-20 outlet in their garage and it’s 5 feet from the garage door. But that means the garage door can’t be fully closed and he’s worried about critters getting in since he live in a rural area. Any suggestions on how to handle that scenario when charging away from home?

This was a lot more satisfying than I expected! Thanks Dave!

First of all. It is so important to have a great microphone while recording, you sure have checked that box. Secondly great video.
We keep a 40' 12/3 in the car, too. We haven't needed it yet, but it's there in case we do. Good video, Dave.
Thank you for this information
Great information and things to consider. Thanks Dave
I use a 10 gauge cord, and it works just fine.

Try driving closer to the plug.
Great Video!
Thanks for also using international units, not just US local units.
with higher load, the voltage will drop proportionally
Tesla tells you not to use extension cords when using 110v.
Tesla isn't unique in this warning. My Honda Clarity has the same warning about using extension cords with the OEM evse.
One question, if I use the 50amp nema 6-50 extension 75ft from the third floor to the first floor there is a 25ft drop from top to bottom will there be any problems? I set the charger to 32amp, it will only use 70%, the extension is a 6 cable that can withstand 50amp.
What is your voltage at the outlet with no extension cord? I know you said you have 124 at the breaker.
Same at the outlet, it’s feed with 12/2 Romex from the circuit breaker
very nice video! I live in Switzerland where standard outlet is 230v. Would it be possible to charge my tesla with a 100m (300ft) cable? I know, weird request, but I live in an apartment with indoor parking and the cable has to be that long... It would be one cable with no plugs in between.
Tesla states in the manual not to use extension cords or splitters. I know some situations are a challenge but do you want to void the warranty?
It was a test, to see how far a wire can be
Thanks Dave. Do you have any recommendations for an extension cord for 110v emergency use when on road trips?
I would keep a 100’ 12 ga extension in the Frunk because it’s better to have it and not need it than to need it and not have it
Does the grounding of an outlet make any difference? If an outlet is not grounded, will the Tesla charge?
The relation between neutral and ground is checked by the mobile it wall connector before allowing power to flow
It’s the connectors which cause problems
Hi. Is the tesla 110v charger plug waterproof for when it rains and snows? Would the extension cord be ok in rain and snow?

Xanthopteryx yes I needed to see one of these comments because it’s clear that people didn’t do their research
Proper installation by an electrician might set you back $1,500 - $2,000 depending on how far the wiring needs to be run from the breaker box.

I'm getting 12/16A 111V from a 5-20 with a 20ft extension, about 1.33kw
The mobile connector limits 120 volt AC circuit to 12 amps max. Continuous duty cycle is usually derated by 20 percent. Check with an electrician
Dave great, usable information as always. Do you think it’s safe to run 125’ of Romex 6/3 wire from a 200 Amp panel using a 50 Amp breaker?
There are some online wire gauge voltage drop calculator you can use. Your case seems fine to me. I'm not responsible of your installation of course :)
@@motofan16 Thanks for the reply. Won't hold you to anything!😊
Depends on the job, best to consult electrician as he can evaluate your setup to best operation
First like and comment 👍
For some reason I can’t charge using a 25 ft heavy duty cable. The letter T on the charger is red. The cable is 12 gauge. Any reason why?
Your plug probably needs work, try another plug on a different circuit breaker. Can you plug the mobile connector into the offending outlet and does it work?
@@evdave528 I got it fixed. Who is the cable itself even though it was brand new and heavy duty but I end up buying yellow jacket cable and it works like a charm
OmG I can't see you dave🤓
Why not feed the car with 230V? The los would be lower. The current 1/2
I know but this was a regular house current test, most homes in North America use 120 volts AC as standard. When traveling you are more likely to find 120 vac

The Tesla shows it in Miles per hour of charge. At 120 vac it’s 4-5 miles per hour and 48 amps at 240 vac is 43-46 miles per hour
10 and a half minutes to answer a yes or no question.
How much money does this old man have 😂😂
👍🏽
Plug losses.
Watch this at x2 speed
That won't help Dave charge any faster. :-)
Love tesla, but hydrogen is the future.
On what planet? It’s inefficient, costly and virtually no place to get it. A battery electric car is way superior. It used the energy directly.
Just post the answer, don’t need a 10 minute video.
If you do not understand the process you can not understand the result.
