Basic adapter kit for R1S and Model Y, 50A home receptacles

[ForeverOnTheWaitlist]

We have a Model Y and soon an R1S. What basic adapters should I have for road trips to maximize my charge options for both cars.

We have Nema (14-50's I believe) receptacles in our garage for charging (4 gauge romex connected to a 50A breaker). From reading a few threads, sounds like I can put a 60A breaker on 4g Romex and get moderately better charging speed without rewiring. Given our Tesla/Rivian combo, are Nema (14-50A) receptacles (vs some hard wired charger) a good solution ?

For home charging it's better to have hard wired stations. People sometimes have problems with overheating plugs. Especially at higher currents and with cheap sockets.

Thanks, I saw a photo in one thread which someone else believed was bad wiring. Must be chargers out there that will work on both cars.

I currently charge an Ioniq 5 and Model Y using a Grizzl-e Classic charger plugged into a NEMA 14-50. Just use the adapter when charging the Tesla, works perfectly for us. When we get our R1S, plan to still maintain the same set-up.

We have an R1T, Y and an R1S coming shortly. The Rivian charge rate is 1/2 of our Model Y, so we hardwired our Rivian Charger with a 60A breaker to get the full 48A. That is a must IMO if you have the power available. At 48 amps the Rivian charges about 22-24 miles per hour and at the same 48A the Model Y charges at 45 miles per hour.

We currently share the Rivian wall mounted charger and use the adapter that comes with the newer Model Y's. We'll add another charger soon. We also doubled the size of our solar system and Tesla Powerwalls, so we built a gas-station at home. Never on the grid to charge.....

For the road I have RV park adapters (small and large) NEMA dryer, 50 ft. welding cable extension and a few others. I'm sure people want the links, Tesla adapter for hotels that aren't J1772...

I have a Tesla Model S (2014 originally, currently a 2018). I used a tesla mobile charger at home for 9 years. But it was never unplugged so no worries on the NEMA 14-50 plug. But it was limited to 32A. For the Rivian I wanted the full 40a plus I wanted a smart charger I could set timed charging on, so I went with a Chargepoint Home flex charger. So that's J1772. For the Tesla I use the Tesla provided J1772->Tesla adapter, for the Rivian I just plug in the J1772. We drive a lot but I still dont see the need for more than one charger.

How do the Rivian and Tesla wall chargers compare ? I know both can be used with both cars (given adapters).

The rivian one is overpriced and constantly out of stock. The Tesla one is readily available and has a long history of working well.

I have a Tesla HPWC signed by Elon (referral award) unopened. I chose to buy the ChargePoint instead of calling an electrician etc to use the Tesla HPWC.

Too bad the charge port change won't happen sooner. Then I really could have just bought the Tesla charger with no adapter at all.

You can buy a Tesla->J1772 adapter now from Lectron and others. It wont work for SuperChargers but works for the destination, home and portable chargers.

We have a Model Y and an R1S on the way.

One big benefit to Tesla Level 2 chargers, is they support power sharing. So if you add 2..n Tesla chargers, in my case one NACS and one J1772, they can delivery full power if only one is plugged in, but reduce power output if both vehicles are charging. Tesla Gen 3 NACS EVSE has been rock solid for us, and it sits outside all year long.

Good to know. Still wish Rivian would swap it's port for NACS but not likely to happen. I guess the Tesla charger with that adapter is my best bet. I'll likely need that adapter anyway for charging at a Tesla charge station.

They said they would start putting NACS ports on vehicles in 2025. (I guess it takes time to change bodywork, wiring, etc.)

You could get the Tesla J1772 charger to avoid adapter when charging at home. Having adapter on road trips is definitely very helpful though.

For my use case, we have one Telsa NACS wall connector for Model Y, and one J1772 Tesla wall connector for R1S.

I have found NEMA 14-30 and 10-30 adapters to be “must have” along with a 50+ foot extension cord if you’re staying in Air-BnBs and want to charge. I prefer booking a unit with EV charging, but sometimes I can’t so I’ll scope out the listing and if I can determine there is an electric dryer in reasonable proximity to a parking spot then I can still book it.
