Am so glad I found this tutorial, we will be taking our first road trip to visit our grandkids in Maryland and they have an unused 5-20 outlet in their garage. So I bought the Tesla pigtail. The outlet is in on the back wall of their garage and after seeing this video I asked my SIL to measure the distance to about where I could park my car and turns out I need another 10 feet or so, so I will buy a 5-20 extension. But your best tip was to increase the charge limit. I assumed the car would just see the plug and adjust it automatically. I would have lost 2 mph of charging speed. Thanks so much.
Thanks for the kinds words. I'm glad it worked out for you!
Yes like everyone else in the comments are saying, thanks a bunch for this.
Thank you for the video. It helped me.
well doe. Thanks for the info..cheers from NYC!
Thank you for this. I've ordered a Tesla and looking at home charging. Just last week I noticed that I had this socket in my garage. I had to look it up. Oh, and thanks for showing how to increase charging current.
Good luck with the new car!
Did you get your car yet?
I’m getting mine also, and I also have this Nema 5-20 in my garage. I’m so excited. Did it work out for you at 6 mph?
@@chezchezchezchez Getting the Model 3 on Wednesday. I decided to go ahead and get the 14/50 installed. That's because I've also ordered a Model Y that is supposed to deliver in December. I figured that two cars would be tough to keep properly charged on the 5/20
Thank you!
I charge with the 16 amp plug like you are showing in this video and was having issues with my battery not lasting long on my model 3 performance. I talked to a tech at Tesla and he said always charge to 90% when using this slow of a charger which I now do and it has made battery last longer. My concern is when I set the car to charge to 90% and unplug it, it jumps up to 93% by itself while sitting there unplugged EVERY SINGLE TIME! I don't understand and I get worried leaving it at 93%
When you set it for 90 and it ends up higher is not a problem. It’s just that the BMS (battery management system) is adjusting the results of the cell voltage readings. Regarding what the tech, I have never heard of this before. L1 and L2 charging are both trickle charging compared to DC charging and don’t need a 90% max. You could charge anywhere you like between 50-90% for NMC battery packs for daily driving.
@@MTNRanger I was thinking that but you know how it goes from tech to tech, one thinks they know more than the other and gives different info but it seemed to work for me. Here in Henderson, NV we have a Tesla Remote Technical Center and I am thinking of working there, I think it would be a fun job! I talked to the supervisor and he said he would hire me in a heartbeat so I think I am going to try it! Just thought I would throw that in there! Thanks for the response though! You are great!
@@Magnus_Magnusson_702 Interesting! Let me know how it turns out.
Nice Video. I was looking for the same. BTW if we use 15 amp male to 20 amp female still we can get power of 16 amp or 12 amp. Also I bought Lectron level 1 charger which comes with 6-20 plug. So can I use any extension with 12 AMG which outputs upto 250 volts?
Q1. You need the all the connections/equipment to support 20 A for it to use 20 A safely. If there is a mix of 15 and 20 A, 15 is the max you can use. Q2. My video is focused on 120V charging. In your situation, the EVSE's 6-20 plug will require an extension cord as well as outlet and breaker that support 240 V. If you do have a proper NEMA 6-20 outlet/breaker combo, this extension cord looks good: amzn.to/3Ws7z4g
Is that safe enough to do if it the UMC/extension female connection are in the rain?
I used an extension cord with my UMC outside for about a year while my garage was being built. If there is a chance it may get submerged, place the MC in a plastic box to keep water out. You could put a weather proof cover where the wires connect. amzn.to/2UohlbY
Does using the 15 amp male to 20 amp female adapter slow down the charging rate or can you still possibly get 6 miles/hr?
There needs to be a NEMA 6-20 connection all the way to the outlet to the car. If you convert it to 6-15 at any point, it will go slower.
@@MTNRanger Do you have to set the "Charge Current" setting back down to 12 amps when you use this set up with a 15 amp to 20 amp male/female adapter with the Tesla mobile connector using the 5-20 adapter?
@@delaware137 Yes, you need to manually turn the amp level down to 12 if you use a 5-20->5-15 adapter on a NEMA 5-20 outlet.
@@MTNRanger Thanks for the rapid rely, but don't you mean a NEMA 5-15 outlet. I have NEMA 5-15 and 5-20 outlets in the parking lot at work. I don't want to switch out between the two Tesla adaptors all the time and was thinking of using the 5-20 Tesla adaptor with the cheap 5-20->5-15 adapter when only a 5-15 outlet is available.
@@delaware137 I just tried it using the NEMA 5-20->5-15 adapter attached to a 5-15 outlet. The mobile connector will use the amp setting of the NEMA 5-20 attachment and not the 5-20->5-15 adapter. So be careful, you need to reduce the amp setting to a max of 12 on the charging screen.
Thanks! Outstanding concise video! First one I’ve seen on this topic. I’m getting that extension AND the adapter for 5-15 outlets.
Thanks, I hope it works out well.
Max Amp is going to be the weakest link. 5-15 80% max Amp 12 the circuit is 15amp 5-20 80% 16amp be careful.
Is it okay to charge regularly with extension chord I doing at home my car cannot get in my tiny garage so 110 is far from my driveway I charged last 2 days no issues so far got 12awg/20amps max from HD.
I used mine for a year until my garage was built. As long as the extension is good gauge (10 or 12) and well made, I don't see a problem. Check for any excessive heat at the ends after about 30 minutes of charging at the highest rate. Also check it every month or so to make sure it's working well.
@@MTNRanger mine is 12 awg/3 15 amp, 125 volt dont see any super hot at the receptacle it's slightly warm though I have been checking intermittently since yesterday did not feel any hotness around receptacle or male/ female connector that connects to mobile charger
@@goodyoneloves That's good. Almost all failures will occur at the plugs (unless something cuts the cable itself!)
Do you protect the charger from rain, if so how do you do it ?
When I charged outside for a year, I just made sure the mobile connector and wire connections were elevated a bit - you don’t want it soak in water. If you are charging outside for a long period of time, a weatherproof connector cover for the cord may be a good idea. amzn.to/3jyEkKl
Good video-I too got the cord and adapter for my new S Model Plaid👍
I use an adapter that allows me to combine two NEMA 5-15 outlets on different breaker poles to make a 12a 240v NEMA 14-50 receptacle and carry a 50ft heavy duty low gauge extension cable to make sure I can reach 2 outlets on separate poles. I also have a NEMA 5-15 to NEMA 5-15/5-20/6-15/6-20 with a switch on it for safety to prevent back flow of electricity. Super handy!
I also carry adapters to change all common dryer sockets to NEMA 14-50. 10-30, 6-50, and just today purchased a 14-30 adapter. I have a 30ft 14-50 extension cord, but it's too heavy and inconvenient to bring around though, so I just use the 5-15 combiner in the cases where the 14-50 or other dryer outlet are too far.
I never got a combiner adapter for testing since all my exterior outlets are on the same pole. Carrying adapters is handy for trips. I try to choose hotels with destination charging when possible.
@MTNRanger yeah, I usually combine 2 and have it go under the garage door.
Thanks for making this video. I learned something new today.
A nema 5-15 plug will fit into a nema 5-20 outlet, so can you use the 5-15 and raise the amperage to 16 amps? I don't see the need to get the adapter, since the plug fits both outlets.
No, you need a NEMA 5-20 to get 16 amps. For example, if you have a NEMA 5-15 dongle on a mobile connector, it will go up to 12 amps on a NEMA 5-20 outlet, no higher. On the car's screen, you adjust it, the max it will show is 12.
So I see you’ve suggested buying a weatherproof cover for the place where the 2 cables connect but what about where it connects to the car is there anything we need to do/worry about with rainy weather?
Where the Mobile connector attaches to the car? Yes, that is water tight. I’ve done supercharging in a storm before.
great video. This is exact what I need. Thanks. Do I need to worry about using this during rainy days?
Technically the mobile connector is not water proof. But I keep mine outside on an extension cord for over a year with no issues. For a semi-permanent setup, I would get one of these: amzn.to/3Y1mfar
Perfect, thanks.
why do i keep getting fault not charging
It can be for a number of reasons. For example: Incorrect outlet wiring, voltage drop, breaker issue, other appliances on circuit, etc. Is the charging unit the only thing connected on the circuit? Have you tested charging at a low amp level like 6? An outlet tester is also good to see if it is wired correctly. amzn.to/3PaJx8U
when I use with extension cord of 110v outlet in my screen it shows that 'Charge rate reduced/ remove extension cord or check wiring' warning also over period of time the charge rate slowing down from 12 a to 6 a. Is this normal or any issue with my outlet?
It could mean the extension cord is defective or not a thick gauge (10 or 12 AWG is best). Or it could be the outlet itself. If other outlets/devices are on the circuit, that could cause this problem.
@@MTNRanger it’s 12 AWG 12/3 gauge. What I observe is It’s happening when weather is hot
@@suryachu1 I would have the outlet checked for loose wiring.
I have had this problem on and off for over a year. I have a Southwire 50' 10 gauge cable and upgraded to a Hubble 20 amp GFCI receptacle to no avail. I still get "reduced" throughput due to supposed overheating.
