Back when I first got my R1S several years ago, I installed a third party Sirius/XM satellite antenna and FM modulator to listen to it via the car’s radio system. Works fine. I finally tried the now built in streaming version of Sirius/XM and found that the Fox News station (channel 114), at...

No advantage going with the Rivian wall charger other than looks maybe. It also costs $800 vs $580 for the Tesla. You'd want to get the Tesla Universal Wall Connector for the Rivian (https://shop.tesla.com/product/universal-wall-connector). The thing I like about the Tesla is that when if you...

Yes, that’ll work fine with the Rivian included portable charger. Wouldn’t be a bad idea to replace that receptacle with a Hubble or Bryant one just to be on the safe side. Although the Rivian portable charger will draw 32A out of that 50A rated circuit, so it isn’t pushing it too hard.

Ideally you want 48A/60A circuit charging for each handle type (NACS/J1772) if your goal is to provide useful power for a couple of hours charging.

Sure, if you want a gold plated commercial solution that’ll set you back thousands of dollars per port.

The problem with installing just 14-50 receptacles is that will generally limit charge rates to 32A (most portable EVSEs limit out at 32A). Whereas hard wired EVSEs can do 48A. Does the campground have an anti-Tesla bias? Sounds really weird.

So of course the Tesla Universal Wall Connector (https://shop.tesla.com/product/universal-wall-connector) is the one to get since it has both a J1772 and a NACS handle. $580. Otherwise, get a J1772 one (which will be obsolete in a few years as new cars will come with NACS ports, but whatever)...

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.

Reply to my DM. Seems I have others waiting. Thanks.

$160 including shipping. Used once, works. I'll accept Paypal, Venmo, Zelle. Shipping from San Diego, CA.

Fun fact, EV chargers do not use the neutral pin when charging from 240V sources, which is the bent blade or the straight blade opposite the round ground on the 50A plug. So that means you can take a hack saw or dremel to the neutral blade of your Rivian 50A plug to remove it and it’ll plug in...

I'm an early R1S customer, and I finally got my email asking for a shipping address. So R1S customers should start to see those emails.

You can make or buy your own 5-20 to 14-50 adapter, use the Rivian mobile charger with the 14-50 plug, dial down the amps to 16A and you’re good to go. More info: https://carcharging.us/home-made.php

Look, this is still a lab based battery technology that needs to be scaled into volume production. Tesla has been trying to do this with their dry electrode 4680 form factor battery cells for five years, and while they are finally ramping into meaningful volume production numbers, they still...

If the two 30A receptacles are on different phases, then this might work. I say might because there are fault conditions, or the use of a GFCI, which would make this not work. If you are charging overnight, chances are you don’t need to do this, just get an adapter for a single TT-30 to a 14-50.
