Charging Tesla from a dryer outlet

[ivolvo]

I plan a trip to the north part of Wisconsin where Tesla Superchargers are rare. I rent an Airbnb house and wanted to inquire the owner whether it is possible to charge from the house dryer outlet. To extend the reach I planned to buy a 50' extension. Before doing this I wanted to check:
1) is it legal to use the outlet for this purpose
2) what would charge rate I should expect for this setup

Is it a reasonable and recommended thing to do in general?

I did exactly that when I traveled to the UP of Michigan last year.
1) Yes of course it's legal. Just be sure you have permission to use it, as you say.
2) You can pull 24A on a dryer outlet. Easily sufficient for overnight charging.

You will need to know if the dryer outlet is 10-30 or 14-30, though probably best to just have both UMC adapters (though that makes your use of an extension cord more difficult).

Be careful, many houses in this area have gas dryers instead which just have a regular 120V 5-15 outlet, which won't really help you. So be sure what you're getting.

Also keep in mind that any house with an electric range is also just as usable, and who knows, maybe the kitchen is easier to access than the laundry room (which is often in the basement). Electric ranges use 10-50 or 14-50 outlets (and again, a gas range won't help you).

I assume you will be using your mobile adapter. Quite a long time ago I used my dryer outlet (240 vac at 30 amps), which means I was charging at 24 amps. I think I was getting at least 20 mph of charge on an X100. I hope you choose an extension with a big enough gauge to handle that amount of current. 50 feet is pretty long. And does your mobile unit come with the right adapter?

Be sure to test the adapter at your own house before you rely on it on the road...

Yep, first, find out if the dryer's electric, then get the right adapter. RV stores have those long extension cords that can carry the high amp loads

That’s how I charge at home
Seems like 2.5 - 3 hours per 20% of charge
I also have a 50’ extension lead and have had 0 issues

got the lead from amazon btw

 

[TyH2009]

That's how I charge at my house, 30A breaker, charges at 24A, roughly 22 mph.

Yeah, you just need to find what adapter you need or just get the whole package.

Charge rate is also listed there.

I use a dryer outlet at our camp and at my parent’s house. Tesla was out of the 14-30 pigtail for the mobile connector when I needed it so I did the unthinkable and made a 40ft extension cord out of 10/3 soow with a 14-30 male end and a 14-50 female end. Then I just used my 14-50 pigtail that I use at home. I reduced the charging rate in the Tesla to 24 amps. Now when I visit these places the car recognizes the location and uses the prior charging profile.

Your biggest issue will be if the dryer is electric and what plug does it use. Good luck.

I would use the thickest gauge extension cord you could get. That’s a lot of juice to push through a 50ft extension. . .

I use a Dryer Buddy, works great. 14-30 plug. I made up extension cord so I could go through a wall.

I typically use my 5-15 outlet (I don't drive much), but I did get a Y-cable for my dryer outlet (14-30) and use it when I need some extra juice after a trip. Works great and much cheaper than getting a new outlet installed.

Thanks to everyone. Your information really helps.
The extension I had in mind: https://www.amazon.com/gp/product/B07TCCFFZQ/ref=ox_sc_saved_title_1?smid=A15AM8MHT45F3Q&psc=1. Is this the right one?

That works, on "newer" dryers outlets. Lots of homes may have the older 10-30 dryer outlet. You need to find out which your homeowner has.

what he said. The male end will depend on how old the outlet is. I misspoke above I made my extension cord with a 10-30 male end.

 

[jrweiss98020]

No. That's a 14-50. Check your dryer outlet. it's probably a 10-30 like this:

Here's a nice resource for figuring out what a certain plug / socket is:

Before dropping money, find out from the owner what type of plug it has. He or she may not know by name (NEMA code), but a clear photo would allow you to look it up on a site such as the one RayK mentioned just above.

You may want to get a splitter so you don't have to keep swapping plugs. The dryer outlets are not usually robust enough for constant plugging/unplugging. Here is the one I use in my rental house https://www.amazon.com/gp/product/B07MW77WM2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

That’s the one I have, no issues and we use it daily
