Campsite experiences: is 14-50 or TT-30 more common?
- Thread starter neutrino
- Start date
Older parks are much more likely to be TT-30. Newer parks usually have 14-50.
In the RV world, they call the TT-30 "30 amp service" and 14-50 "50 amp service."
You can usually find listings for any given campground that will show one or both of those.

So the 14-50 adapter is like $35 from Tesla, it used to be standard and you really should make sure you have one.
So the real question is for the probably $60-75 for the third party TT-30 that will cost, are you willing to risk not having it when you could need it? It will probably get you about 10miles per hour maybe more which is certainly worthwhile.

Here is a $20 adapter TT-30 -> 14-50.

Set the charging amps in the car to 24A and it will work fine. Better than $40/$60/$80.
Have you actually tried that particular adapter?
It looks like an RV adapter, which generally works by connecting both L1 and L2 to the single line in of the TT-30, and the TT-30 neutral to the 14-50 neutral.
That’s great for two 120V banks both running to neutral in an RV. For an EV that’s connecting across L1 to L2 to get 240 V for charging, not so much. With both sides connected to the single line in, there’s no charging power.
The EVSEadapters custom pigtail has advantages over a correct EV charging adapter because it has the thermal monitoring at the plug of the UMC intact and functional, and also passes the correct charge current limit to the car.

This right here is the key. Small travel trailers are OK with 30A service, but if you come in a 40' diesel pusher with multiple A/C units and lots of appliances, you're going to need 50A, which means a 14-50 plug. Most campgrounds will charge more for a bigger spot with 50A service (which is also more likely to have full water/sewer/cable hookups). Some places won't rent you a big site unless you're driving something that requires it, though I don't know if they would ever enforce that.
And if you want to check for this, sites like www.allstays.com or www.rvparky.com have maps of the campground sites state by state where you can filter by amenities like 30A or 50A service.
Just because the plug type fits, it doesn't mean it will charge your Tesla. Don't buy those cheap TT-30 to 14-50 adapters on Amazon like the one User212 posted, they don't work.
I use this one and it’s a well made molded plug adapter.

This is the one required for TT-30 sites.

You keep spamming that into tons of different threads. It's not relevant here. That is for adapting to 14-30 outlets for electric clothes dryers. That has nothing to do with the outlets at campgrounds.
I bought one of these and was glad I had it.
I stayed in a State Park electric site with both 50 amp and 30 amp service, but the 50 amp service I had planned to use wasn't working.
“Tons” sounds like a lot... like you exaggerate. It does plug into a campground 30A, 50A, and your house if you install a 60A. Not a difficult concept.
Not a 30A campground connection. That would be a TT-30, which it won't fit. It'll plug in to a campground 14-50 and work just fine - but you could plug your native 14-50 pigtail into that without the adapter, too.
Please explain what you are talking about. The 30A outlets at campgrounds are TT-30, which are 120V 30A, and they look like this:

Your cord does not fit that.
As @Saghost points out, you may have been talking about plugging into the larger 240V 50A outlet that most campgrounds have. But that is a 14-50, which is what your Tesla plug already is. You're just adding an unnecessary 1 foot extension cord for the same plug type.
There are some other really strange places that make 14-30 electric clothes dryer outlets available for various reasons. When people were trying to travel I-84 through Oregon and Idaho several years ago before Superchargers, someone found that the Baker City Truck Corral had pay-per-use pedestals with 14-30 outlets in them for some reason. I hadn't thought that semi trailers used those, but that got added to Plugshare for Tesla drivers to use. But those are almost never found at any campgrounds, and it's confusing people to say that is the 30A outlet at campgrounds.
