Should I just keep my Tesla charger and use the adapter? Is it still necessary to own the Rivian charger? I know there are many unknowns, just curious on everyone’s thought.

I'd keep it if you already have it installed. There's no particular downsides to it.

A Rivian charger is a charger with Rivian's name on it. There's nothing about it that's specific to the vehicle.

With the changes recently I would keep the Tesla NACS charger. I have two Tesla power walls. One is the J1772 version and the other has the NACS (Tesla plug). My wife is getting her R1S soon and so I will be purchasing the 60 amp Tesla Tap Mini adapter.

I'm choosing the adapter because I can also use the adapter away from home if needed. Another option, because both versions use the same backing plate, would be to swap it with a J1772 Tesla wall connector but after selling the existing unit cost would be about the same and I wouldn't have the adapter to use away from home.

Add to this the fact that Rivian will be switching to NACS in 2025 and it's clear to me the adapter is the way to go.

NOTE: Rivian has a larger grounding pin and some folks have had problems with the Lectron branded adapters. TeslaTap has made a revision to theirs for the Rivian and so I would only recommend TeslaTap. The TeslaTap Mini 60amp is $259 direct from their website as of this writing.

Always good to have a backup L2 EVSE in case one of them breaks down.
We had an issue with our Tesla Wall Charger recently, so we used the J1772-to-Tesla adapter (the one that is included with Tesla vehicles) to charge the Tesla from our JuiceBox EVSE. If the JuiceBox broke down, I would have used the Tesla-Tap to charge the Rivian and i3 from the Tesla Wall Charger.
The EVSE equipment can fail, so a backup is really great to have, and in our case we have three EV's so at least one working L2 EVSE is a must.

I am super confused. I took delivery of my R1S last Friday. My house that I purchased in 2019 came with a Tesla wall charger. It’s wired to a 100 amp fuse.

i bought the Rivian charger when I ordered the R1S in 2021. Do I keep or sell?

Can I buy this TeslaTap mini and use existing Tesla wall charger? What amp adapter should I use?

The cable on Tesla charger is super short so I will need to back in to charge, or is there a longer cable that will adapt to existing 100 amp Tesla charger?

The Rivian only has an 11.5kW charger, so 48 amps is as high as you can go. The Rivian charger has a longer cable and a CCS connector, so you won't need an adaptor and should be able to park either way in your garage.

Extending the length of the charger cable with an extension may be a violation of the NEC as well...

I would either keep the Rivian charger or sell it and get the Tesla J1772 wall connector instead. I installed the Rivian charger last year, but if I were buying a charger for a Rivian today, the Tesla J1772 is the one I'd get. Like the Rivian charger, it has a 24-foot cable.

It sounds like you have an older Tesla wall connector. The older units had shorter cords and could charge up to 80 amps (hence the 100 amp breaker).

The Gen 3 Tesla wall connector has a longer cord and a max charge rate of 48 amps.

How far is it from the breaker panel? If they have an 80 amp load and a 100 amp circuit the wire is probably too large for the Rivian or gen 3 Tesla charger. They should have used #3 or #2 wire for this install if it was done to code. Tesla Gen 3 can't accept anything larger than #4 and most are installed with #6. If it's installed in conduit....which it should be in your case....it may not be too big a deal.

If you want to save some $$ just get the 60 amp TeslaTap and back in. Otherwise you need new wire, swap 100 amp for 60 amp breaker, and you can install either the Rivian or Tesla charger. I have the J1772 Tesla Wall connector. I also have a 3rd gen on the other wall with the Tesla NACS connector. They load share which is a big reason why I like the Tesla chargers.

I believe you are correct. The wire in the wall now is too big to even fit my Rivian wall charger or J1772. I went to an electrical supply house and explained my situation.

The counter guy was very helpful. I need to swap the breaker to a 60 amp.

He also suggested I just run new 6 AWG wire through 1” flexible conduit to the front of garage. The Rivian charger has a 25 foot cable so should reach either bay.

If you want to swap the charger post some pics of your current charger install and your breaker box with location in relation to the charger. We can give some general advice.

If your going to do it yourself you may be able to pull new wire through the existing conduit (assuming you already have conduit). Also with #6 wire make sure you get the right wire. I used THHN 90C which can go up to 75 amps. Wire needs to be rated at least 60 amps.

If you do the work yourself get a permit from your local permit office and have them inspect the work after you finish. Will give you peace of mind for the future.

I found the Tesla Owner's Manual for my wall charger. It is a 80A Single Phase charger, thus the 100A circuit breaker.

I have thought of using it and buying the TeslaTap Mini 60 Amp. I figure carrying it in the vehicle as an emergency back up can't be a bad idea. Thoughts? Or is this like throwing good money after bad ???

The wire in the wall from panel to charger is too big to fit the Rivian wall charger I purchased. Rivian uses #6 wire like you say. If I am going to run new wire, I might as well run new conduit to front of garage to facilitate charging of Rivian.

Lastly, I could try to sell the Tesla 80A Single Phase charger to recoup some of my investment.

My truck likes the distinct flavor of electrons my Rivian L2 provides
It only mildly tolerates the wife’s tesla charger electrons

You can pig tail the wire down to a #6 on the charger end - that will save you a LOT of money in copper and labor vs pulling out and throwing away hundreds of dollars of wire and re-threading it with hundreds of dollars of new wire. You will of course have to also swap the breaker to be 60A to ensure that no one can put 100A through that #6.

Or keep both on separate 50amp breakers or 60s if your load center has capacity. Future proof for 2nd ev
