72 amp charging?

I am curious also, as I have run into destination chargers where being able to charge at 72A instead of 48A was helpful and a time saver.

I wouldn't say they cheapened at all... It was an option that the majority of owners didn't order.
As for adding them, we've talked about it for years with our 90s and the costs aren't worth it (thinking $4k+), nor are the service centers enabling them any longer.

They are physically different parts, so it’s not a matter of adding an additional piece of hardware like in the older cars. The old one comes out and a new one goes in.
For awhile it was not an “option” My 2018 MS100D came with 72amp charging standard. My new MS100PD (equivalent, I realize it’s now LR) not only didn’t come with it, but I couldn’t order it as an option. Hence why I said they cheapened out on it.
As I understand it, the charging consists of 24amp chargers with the cars getting two installed for 48amps, you used to be able to get a third installed (or standard) for a total of 72amps. I’m trying to find out if I can install a third 24amp charger...

There used to be either two or three 24A charging boards as you suggest, but they were contained within a single physical housing. That said, the 48A and 72A onboard chargers were different part numbers and there’s no way a Tesla service center is going to crack one open for you and install a third internal board.
I’ve seen suggestions that the current 48A S/X onboard charger uses 3x 16A boards like the Model 3/Y does, perhaps for supply chain simplification/standardization, but I haven’t come across any confirmation of that.

Between when Tesla introduced S/X with 100 KWh battery packs and when they decided to standardize on 48A charging, there was an option to purchase a 72A charging upgrade.
And Tesla actually installed the 72A chargers in at least some of the S/X models built in that period, and then software limited to charging to 48A.
When I checked with Tesla, they verified our 2017 S has a 72A charger onboard, but to do the upgrade from 48A to 72A, we'd have to pay the same price to do the upgrade as if we only had the 48A charger on board.
Our 2018 X has a 72 charger, and we charge it on a wall connector set to 48A (on a 60A circuit), and that charges fast enough overnight.
So far, we haven't used the 72A charging capability on the X, since we charge at home at 48A, use superchargers on road trips, and use a 30A dryer outlet when staying with family.
And this is why Tesla likely decided to standardize on 48A and reduce the cost of the onboard chargers and the mobile connectors.

Sorry late to the party here, but I just called my SC for my 2018 Model S 75D (late Feb build) and I was told that my car already has an onboard 72A charger which is software limited to 48A and to get the "upgrade" it owuld be a software upgrade only with a cost of $1000! WTF!!!!

Tesla has an options page? Can’t wait to see it. Let’s see.. where is the real steering wheel?

I love my dual chargers and my Gen2 HPWC. As / when I look for a newer Model S, the 72A charger will definitely be on my list of wants. It’s an error (IMHO) for Tesla to no longer offer it.
Why? We have limited parking so I often pull the S around the back of the house to charge and then move it when it’s done. Being able to charge in a few hours makes a real difference in convenience. Plus our service is only 208V, not 240, so at 40A I’d only be charging at just over 8kw.

My 2016 S90D charges at up to 80 amps in my garage. The car has two 40 amp chargers. I have an HPWC connected to a 100 amp circuit.

My 2013 S85 had dual chargers and I loved getting 60 miles of range per hour. When I changed up to a 2015 S85D it came with the 48 amp single charger and the additional charger was no longer offered as an upgrade. I have learned to live with getting only 28 miles of range per hour. I still use the HPWC that I purchased in 2015 which is rated for 80 amps.

My pre-refresh 2016 from January 2016 came with a single 40 amp charger. I forget when I added the second 40 amp charger but it may have been as late as 2017. I tried a CHADeMo adapter first but that turned out to be a waste of money and I sold the adapter after the second 40 amp charger was installed.
