Help w/ Adapter for 50-amp RV outlet

[DKM_R1S]

Hi, we’ll be visiting a private campground that has a new 50-amp outlet for people with RVs to hookup. I would assume this is a 220V circuit. We want to use it to charge/power the R1S. We aren’t having any luck getting the owner to send a photo or describe the type of outlet in more detail. As of now, I just have the NEMA 14-50 plug that comes with the Rivian mobile adapter. Is a 50-amp outlet likely going to have a NEMA-14-50 socket or could it be something else? Yes, the owner is okay with us using the outlet to charge the Rivian.

RVs that need 50 amps most likely use a 14-50 outlet and plug. Other 50-amp outlets are much more rare.

The Rivian Portable Charger kit's 14-50 pigtail will work just fine in this case.

I have run into some 10-30 and fought an adapter similar to this throw it in the frunk 30 amp is great for camping

I grabbed this one on Amazon as well to adapt NEMA 6-50P to 14-50R as they had an outdoor plug at a national chain hotel I was staying at. 16 Miles per hour, charged overnight just like at home. It's a fringe plug, but for $25 with 5% off, worth throwing it in the adapter case.

Every 50 amp pedestal I’ve used at dozens of campgrounds used the standard 14-50 that the Rivian charger comes with.

30 amp pedestals use the TT-30 which you would then need a TT-30P to 14-50R specifically designed for EV chargers so you can use your Rivian charger at any campsite with electric hookups. Either 15 amp using the standard household plug, 30 amp using the dogbone adapter and the 14-50 plug, or 50 amp using just the 14-50 plug.

That 30 amp adapter mentioned above is also what you need to charge using the dryer outlet at some people’s house. During Hurricane Beryl I did that using my daughter’s dryer outlet when I had no power at my house. The adapter gives you more charging options.

I will echo what everyone else has said. 14-50 is the standard and your mobile charger has that connection. a 6-50 is another possibility but I haven't run into a 6-50 at an RV park recently.

When we take the TT out we ask for 50/30/20 sites. Those will have all the outlets needed. Most of them will have a TT-30 as well which I recommend you get an adapter for.

This way, if your RV/TT uses a 50 amp service you can still plug in the Rivian to the TT-30 and charge at 24 amps @120v. You will need to set this in the truck to avoid overloading the circuit. This will be slower but still allows you to power your RV. Our TT uses 30 amp service so we use the 50 amp to charge the truck and the TT-30 powers our TT.

Lastly, be sure to ask because some campgrounds (like KOA) do not allow EV charging on their camp sites. Most others I know of though don't say anything. I always make sure there is no voltage drop though because if there is and you pull a lot of amperage that could cause a brown out and make others around you angry.

Something like a killawatt meter will measure on one leg which is good enough IMO to tell you about the quality of the power there. Anything less than 115v I would limit the amount of amperage I am pulling. If its approaching 110v then I wouldn't pull any more than 8-12 amps.

Last but not least, you can get one of these Watchdog units. We have them and love them for camping. They have a 50 amp and 30 amp version. They will tell you all the vitals, provide surge protection, and will pop before the breaker pops and you can reset remotely via bluetooth. Highly recomend if you go out with an RV/TT often.

Got my first EV in November 2014 - at that time there was exactly 1 Supercharger in the state of Georgia. So I became very learned about plugs. I have never run into a 50 amp RV service that was not NEMA 14-50. That said, I would never plan on arriving at a Campground/RV location without a plan B. Campgrounds do give priority to RV folks renting for whole for a week. Some campground employees do turn off power when they leave for the night at unoccupied sites and other events happen. Charging 30 or 40 miles from a 110v 12 amp service is not something you want to do -- but it has been done by more than a few of the early Tesla folks.

Definitely do not ask, just use it. Some people are complete morons about electricity and then will start a hassle. Just plug in and don't stir them up.

All RVs have either a TT-30 or 14-50 cable. Some may have an input plug using boat shore power (NEMA L5-30) but the cable will be TT-30. So those are the cables/adapters you need. The TT-30 is 120v and has to be specially wired for the EVSE, you cannot use a normal RV type adapter.

I also carry a 14-50 dual splitter so that two things can be plugged in. Of course, you have to load manage this.

Where 30a adapters go TT30EV <> TT30RV <> 10-30 dryer. As others have said, the only 50a RV plug you'll encounter will be a 14-50 so you are good to go. As a smart person noted elsewhere, the Rivian 14-50 plug can fit a 14-30 receptacle if the unused neutral lug is removed.

Wow, OP asks a simple question and people gives lots of confusing answers.

A campground 50 amp connection IS EVERYWHERE a NEMA 14-50 receptacle which is what your Rivian charger comes with as standard, so you are set.

Recommend you set your power draw to 40 amps max on that 50 amp outlet to avoid overheating it or tripping the breaker. EVs draw lots of power continuously, unlike most RVs.

If using the included portable charger it defaults to and maxes out at 32 amps.

It's not going to be 220 volts, almost certainly nominal 240 volts. I can't remember the last time I encountered 220 volts.
